Spring begins for most, but
Winter stays strong out West

1:10 PM EDT 3/20/12 (Advisor/Meteorologist Justin Berk) While 2011-12 may have been "a winter without winter" for much of the East, a deep trough of cold air has recently produced heavy snow in the West from Washington state to northern Arizona. The enclosed graphic shows the extent of a heavy snowpack out west which has led to an extended ski season for some resorts in that region, including Lake Tahoe. 


Mt. Rainier, WA has been showing off it's heavy snowfall, as indicated by the  images comparing last summer to this week. That's incredibly deep snow! Look closely at the car height and smaller trees on the left and compare to the snow wall on the left. I estimate that is 10-15 feet in snow depth. Wow!


Even Flagstaff, AZ's recent "snowbowl" had a 7-day new snow total of 57". The colder than normal air made it all the way to Phoenix where Monday's high temperature of 58 F was 20 degrees BELOW normal. Contrast that with Baltimore's high of 75 F which was 20 degrees ABOVE normal and you have the extremes more or less balance out.

A warm Winter means 
a hot Spring or Summer?

The quick answer is, no! Back in the east, the end of a long regime of above-normal temperatures has been dangled out like a carrot all winter. It does look more likely that just as Spring begins, a temporary end of the warmth will become a reality. The current upper level pocket of cold air that brought Arizona snow and chill, is currently spawning severe weather in Texas and the deep South, is slowly moving east. That unstable weather should reach Maryland and the mid-Atlantic this weekend. Temperatures in that region should get closer to normal, in the mid 50s, with rain. This may be the first sign of a pattern change for April.

Looking at past years, the first comparison that jumps out is 1990. That year, Baltimore set record highs between March 12-15 with four days in a row in the 80s. The end of the following week, record snow fell on March 24th. Another comparison was the year 1946. The average high temperature was 10 degrees above normal (this current March is +7F). That year was followed by a return to a cooler spring and the pattern did flip in the summer. The three month period of June-August ended up 0.5F below normal. Not much, but a distinct swing from the end of winter. 

While pattern of each year varies, there is good indication that many regions under a drier than normal pattern may not swelter as like last summer. Keep in mind the past two winters were followed by more 100F+ days than many states have ever experienced in a two-year period. Not surprisingly, this extreme heat was followed by below-normal winters in terms of snowfall for those same regions.  

A reversal of fortunes this year? After all in 2011-12, many places accustomed to cold winters saved money on their heating bill, while others in the mid-South saw above-normal snowfall such as the early December 2011 event. Perhaps if this trend continues, the pattern can finally balance out with the majority of places having suffered under extreme conditions can equal out. A cooler and wetter summer might just do the trick, reducing need for air conditioning just as gas prices are beginning a record climb. 

At least we can dream, and hope it will turn out that way.

Welcoming Spring


7:30 AM EDT 3/20/12 (Forecasters Mike N. and Mr. Foot) For some, we have formally bid goodbye to the winter that wasn’t, and can now look back at the season to compare.. which would we have preferred? The frequent breaks of mild air that marked 2011-12, or the storminess and relative cold of 2009-2010? The graphic above from the National Climate Data Center shows in stark contrast how two "winters in extreme" compared.  


A COMPARISON It is interesting to note the third least snowy winter on record (2011-12) followed the snowiest season on record (2009-2010) by only two years. This could be the sharpest two-year difference in snowfall iin the history of climate records. 

A LOCAL REPORT Our Maryland Team reports that Spring was welcomed by thunderstorms and gusty winds across portions of Central Maryland. Quite a number of readers reported observations to the Facebook page of Meteorologist Justin Berk early this morning. 

For that region and across the Mid-Atlantic, the first few hours of spring are opening with milder temperatures what has been seen recentlu. Dewpoints are still fairly high around the region, so we may have more areas of fog as we head out for our Tuesday morning commute. Scattered "Spring showers" moving through those area are kicking off the season right on cue. 

Only problem is... the flowers already showed up before the showers did!

Winter in the West
Stormy in the middle
 Summer in the East? 








Left:  5 feet of snow over 5 days in Tahoe; Right: High of 75 F in the northern Chesapeake Bay on St. Patrick's Day.

6:45 AM EDT 3/19/12  As we move into the second half of March, the weather has kicked into high gear in the central U.S. once again. Energy from the storm which dumped 5 feet of snow in Tahoe has begun tapping warm, moist air from the Gulf of Mexico. This interaction is likely to spin up severe weather noted in the NOAA Storm Prediction Center's Moderate Risk graphic noted below. 


INCREASING TORNADO RISK IN MUCH OF TEXAS 

Meanwhile, many Eastern states will remain quite warm for much of the week ahead with highs of 10 to 20 degree above average. As far as wet weather in this region, showers and storms are possible over the Ohio Valley. For official watches and warnings the affected regions, please consult the National Weather Service. Forecast and Affiliate zones to be impacted by today's weather include our Severe Weather Zone for the Ohio Valley and ConvectiveWeather for the Southern Plains.

IRISH-LIKE STORMINESS IN THE WEST
WARM AND SHOWERY IN THE MIDDLE
FOG THEN SUN IN THE MID-ATLANTIC

8:30 AM EDT 3/16/12  On this commemoration of Ireland's Patron Saint, we hope you and your family will show your Irish colors and be granted good weather for your local parade. Scroll below for our roundup of featured events & forecasts around the country. 


For the U.S. weather outlook, the image above is a composite precipitation forecast map showing areas expected to receive rain or snow in the 24 hour period from 8 AM today to 8 AM Sunday. Are green or blue areas where levels of luck are highest? Not exactly.  These are regions which expect light to moderate rain or heavy inter-mountain snow, but not where needed in those states under Red Flag Warnings.


 Our Parade Forecast Roundup

Much of the Eastern U.S. will escape rain on their parades thanks to persistent High Pressure along the coast, producing some AM fog before events get underway. Featured festivities include:
The Southeast  may see scattered showers or an isolated thunderstorm by mid-day, but not enough to washout celebrations. Featured events:   
The Western States will face the toughest time weather-wise for parades, managing impacts of the coastal system working into the northern Rockies, with heavy rain and snow trailing back to central California. In Salt Lake City, this year's theme of "St. Patrick, Bless The American Worker" will fight back against rainy skies and flood the downtown with a wearing of the green like you've never seen!

    Reality check time. 
    Has our luck run out?

    The Washington DC Cherry Blossoms nearing full bloom 
    Photo by the Thompson family on a recent visit to DC

    11:55 AM EDT 3/16/12 
    (Meteorologist Mogil, Forecasters Natoli and Foot) Sunshine, blue skies, warm temperatures... but not for everyone. While the western U.S. coast receives a strong storm system today, and severe weather broke wide open in the Great Lakes last night, folks in the East get to rest on their laurels and will avoid the perils afflicting other part of the country, right? Not so fast.

    Upper level wind flow map in Mike Mogil's Examiner.com article

    READY FOR THE TRUTH? The Washington Cherry Blossom Festival may actually be the next target for some significant weather heading that way at the tail end of next week's pre-Spring lull. For the eyebrow-raising details on what fate may befall the lovely DC blossoms, you'd better take a look at this special article in Examiner.com by Meteorologist / Advisor Mike Mogil. 

    IN THE WEST The main story in the western U.S. continues to be in the Foot's Forecast | Pacific Northwest as a slow moving storm dumps in more precipitation in that region. Heavy wet snow in the Cascades and the Sierra Nevadas will accumulate several feet as coastal areas receive a strong lashing of wind-swept rain to start festivities for St. Patrick's Day.

    ALONG THE CENTER The tornado outbreak in the Great Lakes and Michigan overnight Thursday into Friday was a reminder that this fluctuating pattern continues to deliver high impact weather with little advance notice. Today, an increased risk of thunderstorms is observed in the southern Plains and the Southeast, which may become severe over Texas, Oklahoma, and Kansas. In the northern Plains, a large portion of counties have Red Flag Warnings in place because of dry and windy conditions increasing the chances for fire. 



    IN THE EAST While folks in eastern states have been enjoying the unusual warmth the past week, repercussions are coming for this area sooner than later. The remnants of the Great Lakes and Ohio Valley storm system have moved to the East, bringing some scattered thunderstorms.

    A summer-like preview, 
    before winter has ended!


    7:35 AM EDT 3/15/12 (Forecaster Mike N.) Did you know yesterday was "PI Day" ? Whether you celebrated with a slice of pie, or a very long number, much of the country with the exception of the west coast experienced quite a hot slice themselves. Temperatures in the 70s and 80s will be common once again around the nation today, as we continue in this summer-like preview before winter has even ended! 

    Today's prime areas for significant weather: Our Pacific Northwest zone -http://www.facebook.com/FFPacificNorthwest 

    A few showers and thunderstorms will be possible near the Ohio Valley, but with the Jet Stream so far north, the primary areas of storminess have shifted into Canada. The U.S. west coast is the only area not seeing the warm conditions as elsewhere, with a major winter storm impacting the coastline today. This storm has brought high winds and wintry weather to the higher elevations of California and the Cascades. 

    In the east, a sprawling high pressure just off the coast will hold the western storm system back for the next few days. Showers and some thunderstorms will slowly build along the Deep South as moisture transport from the Gulf increases, but no significant severe weather is expected. 

    We hope you enjoy this wonderful day along the East and Midwest, and hold on to your hats if you're in Cali!

    9:15 PM EDT 3/14/12 (Forecaster Foot) Star-gazers and sky watchers alike have been enjoying quite an astronomically pleasant show the past few weeks. Jupiter and Venus are slowly reaching "conjunction" in an early evening dance found within your Northwestern sky. For the sake of brevity and celestial enjoyment, we shall defer to this informative and well-done article on the event by Meteorologist and Advisor Mike Mogil in the National Education Examiner. It's a great piece on many aspects of this event.

    If you have a moment, please go take a look at the stunning alignment, and see if you can spot the moons of Jupiter to be found around the "left" star. Many thanks to Forecaster Jason in Newton Falls, Ohio for capturing this image on behalf of our team. You can see the original photo on his forecast page in Facebook for that region.

    2012: Sunshine and Blue Skies
    1993: Superstorm of the Century


     What do you remember about March 1993? 




    9:00 PM EDT 3/11/12 Nineteen years ago this week, if you were anywhere between central Alabama and northern Maine, you would soon be digging out from the most ferocious winter storm to strike the Eastern US in over a century. Heck, if you were anywhere East of the Mississippi, this storm impacted your life. For a scientific retrospective, view this 15-year report published in 2008 by Risk Management Solutions on the storm that changed how we view storms. 


    In the city of Pittsburgh, PA the event became know as the "St. Patrick's Day Blizzard Parade" as discussed in a special Fusion Forecast story and featured on our Three Rivers Zone in southwest Pennsylvania.




    The unofficial title, 'Storm of the Century' seems perfectly fitting for a blizzard that was at times more tropical in nature even though it began as a snowstorm. As an example of it's study in contrasts for just one state: Florida. 
    While northern Florida experienced sustained wind gusts equivalent to a Category 3 hurricane (111 mph), the Panhandle received 4" of snow while storm surges of 9-12 feet pounded the western shore.

    SERIOUS MARCH MADNESS
    • From March 12 to 15, nearly 12 inches of snow fell in every major city from Atlanta, GA to Augusta, ME shutting every airport down between them for over a day. 
    • A central pressure of 960 mb was recorded in White Plains, NY, on par with a Category 1 hurricane. 47" of snow was reported in Grantsville, MD
    • Temperatures in Birmingham, Alabama dropped to 2 deg F...in March! 
    Every adult resident of the East coast today has a "storm story" about this one, and though many of us enjoy big storms, we can count ourselves as lucky that this history did not repeat itself. Powderhounds, we yield the floor to share your tales of this lifetime event.

      What a "Solar Storm" means to you 
      (Example story our team prepared in March 2012 on the largest solar flare in six years)

      "Could jolt everything from GPS to airline travel and power grids"
      -London's UK Daily Mail



      10:20 AM EST 03/08/12 (Meteorologist Alex Davies / Forecaster Foot) Have you noticed any interruptions or problems with your GPS or satellite TV signal today? If so, it was affected by a significant Solar Storm, the largest in six years, which ejected from the Sun on Tuesday and begin arriving at Earth late Wednesday. The video above from the NOAA Visualization Laboratory shows how a Coronal Mass Ejection, known as a "Solar Flare" or "Solar Storm" departs the sun and impacts the Earth. Read more in this TIME.com article.

      See the storm yourself Monitor current data output and even see the Solar energy reaching Earth in this link.

      Is this going to be a problem? "Space Weather" events such as this can have serious impacts on a wide aspects of society. This NOAA video describes how the Space Weather Prediction Center monitors these potentially disruptive events, which include: Space Weather Forecasters to monitor the data and impacts of these events, which include: 
      • Interrupting satellite communications, GPS devices, ground relay stations and cell phone service;
      • Disrupting or terminating power transmission across older inter-state electrical grid systems;
      • Diverting intercontinental air travel away from polar crossings  

      This moderate-to-strong Solar Storm, the arrival of which was is evidenced in this data graph of a "Corona mass cloud" observed by the Space Weather Prediction Center in Boulder, CO.  A storm of this type is not uncommon in the Earth's history as it is associated with normal solar cycles. NOAA's report on this event stated:
      "Geomagnetic storms from these kinds of space weather events can affect the power grid, navigation systems and other technologies. NOAA provides space weather forecasting for the nation, and forecasters at NOAA's Space Weather Prediction Center are issuing updates regularly. The impressive flare from Tuesday evening and a corresponding radiation storm are already triggering high-frequency radio outages at Earth's poles, which could last a day or more, and possible temporary outages on parts of the day-lit Earth."
      You may not have heard of this phenomena before because over the past decade, the Sun's solar activity has been minimal in accordance with an 11 year solar cycle. However over roughly the next decade, the Sun is forecasted to be more active, as we approach a period of increase solar storms and increased electromagnetic discharge associated with the same 11 year cycle.

      For more information about Climate and Space Weather, and what NOAA Scientists do to monitor these potentially disruptive events, please visit this overview page by the Space Weather Prediction Center.

      Action in Pacific points to next pattern

      Water vapor loop of the Northeast Pacific. What patterns  do you see?

      7:00 AM EST 3/7/12 Anxiously looking ahead into the weather pattern for March, we are mindful of the tragedies inflicted on many of our colleagues and communities in the Ohio Valley and Southeast. Heavy wet snow blanketed parts of the Midwest and Mid-South recently ravaged by Friday's tornado outbreak.  Residents trying to recover from 100 twisters in just 24 hours struggled through sub-freezing temperatures and snow earlier this week. We encourage all readers to lend a hand to the recovery effort. Visit the Red Cross website on how you can help affected communities and volunteers. 

      Thankfully, high pressure has settled across these areas for remainder of the week, while the next weather makers will arrive along the Pacific Northwest.  The image above is from the current water vapor loop of the Northeast Pacific. The onshore flow of moist sub-tropical air into Mexico and the Southern Plains is fueling a new upper level wind flow pattern across the U.S. 


      This could be a contributing factor behind the Climate Prediction Center's 6-10 day temperature outlook projecting high probability of above average temperatures across a large portion of the U.S. in the week ahead. The unfortunate long range reality is that unseasonable warmth early in March more often than not gets shot back down again with another barreling cold front. With that front would come more tornadoes. And it's only March.


      Check back later today for additional analyses from our  team of meteorologists and forecasters on the long range potential of a possible pre-Spring "heat wave," and the dangers which may lurk in a persisnently warm and out-of-season pattern. (Forecaster Foot and Meteorologist Randy Thompson)

      8:25 AM EST 3/6/12 (By Advisor/Meteorologist Justin Berk) After Monday's snow showers and clouds dispersed along the East coast, a clear evening sky revealed the perfect venue for a falling meteor! Yes, dozens of reports from Maryland to New England came in around 8 pm with a blue/green streak low in the sky moving from east to west.

      2:10 PM EST 3/5/12 (Forecaster Jason M.) The clipper system moving across the Mid-Atlantic is tracking a bit further northward according to latest observations. Flurries and light snow are being reported by our readers in Facebook as far north as the PA/MD line, The latest NWS advisories for the Mid-Atlantic & Northeast
      • Portions of central Virginia will likely receive several inches of snow by early afternoon. View the latest NWS Sterling snowfall graphic.
      • Winter Storm Warnings were recently raised for Albemarle, Orange, and Spotsylvania Counties in Virginia. Snowfall amounts in these areas may reach 4-6 inches. 
      • Winter Weather Advisories have been extended northward and eastward to the Virginia Tidewater (Facebook) in the past hour.
      • A dusting to less than an inch is expected further towards the Washington, D.C. area. 



                    Not quiet on the western front





      8:00 AM EST 3/5/12  In the east, a fast-moving clipper is dropping an expanding area of unwelcome light to moderate snow on residents of the Ohio Valley and southern Mid-Atlantic in recovery from the tornado outbreak. 

      East of the Rockies, Downsloping winds moving TO the east from the southern Rockies have increased fire risk in the Pandhandle area of Colorado, Kansas, Oklahoma and northern Texas. 

      In the southwest, the combination of an upper level low and a surface high has fueled High Wind Warnings to take effect on Tuesday from the southern Sierras to much of central and southern Nevada.  

      The trajectory and speed of these winds up to 55 mph tomorrow will produce blowing dust and downed power lines for that region, including Las Vegas. Based on these conditions, it could be said this is one time where what happens in Vegas may not "stay in Vegas."

      "Just another manic Monday..."
      - The Bangles


      3:45 PM EST 3/4/12 (Forecasters Foot and Jason M.) The weirdest winter in memory just keeping weirder. Winter Weather Advisories are now posted for eastern Tennessee, eastern Kentucky and into West Virginia/Central Virginia. Some of these areas just experienced EF-3 tornadoes and have only barely begun to clean up. Earlier today, Meteorologist Justin Berk observed that many towns in the Ohio Valley, such as devastated Henryville, Indiana, will have seen severe weather, tornado damage followed by and now snow, in one week. For weather-weary residents of those states, tomorrow looks to be an unpleasant manic Monday.


      OUR LATEST ANALYSIS    
      A clipper-type system diving southeast from the Upper Plains is likely to bring  accumulating snow to the southern Appalachians into Virginia by Monday. The system can be observed on the current Water Vapor loop as a small dark area in the Plains states moving southeast. 


      • This will not be a significant snowstorm and should not cause any major disruptions to the region.
      • The best chance for any accumulation will be in central and south central Virginia (NWS snow graphic). 1 to 3 inches is possible in these areas as noted in the Winter Weather advisories.
      • A light dusting is also possible as far north as a line from Washington to Annapolis. A rain/snow mix is possible along the Maryland/Delaware eastern shore. Visit our Bayshore and Capital Region sites on Facebook for local details for weather in these areas.
      • Uncertainty remains with regard to the exact track of the system. That will make the difference between readers reporting flurries as far north as the MD/PA line or flurries remaining across Southern MD, with the more notable accumulations in central Virginia to eastern Kentucky. 
      (Forecaster Jason M., Advisors Berk, Foot and the Winter Stormcast Team)


      POSTED AT 7:50 AM TODAY: This internal report from our Winter Stormcast Team shows the on-going variability in our pattern this season shows no sign of stopping:
      "Some of the newest model guidance is showing a minor snow event for portions of the Mid Atlantic Monday. The Global Forecast System (GFS) is further northward than the North American Mesoscale (NAM) and has snow as far the leading shield of precip up to the MD/PA line. Verbatim both models show this being the biggest snow event of the season for different portions of the affected areas [noted here]."  - Forecaster Jason M., Winter Stormcast Team
      Compared to this early morning analysis by NOAA winter weather meteorologists:
      MANY OF THE OPERATIONAL MODELS (INCLUDING SREF MEAN) BRING A RATHER ELONGATED SWATH OF QUARTER INCH-PLUS LIQUID EQUIVALENT AMOUNTS ACROSS THE LOWER OHIO VALLEY EASTWARD INTO CENTRAL /SOUTHERN  VIRGINIA." 
      The Surface Low Track map below shows the likely progress of this clipper as it charges east the next 24-36 hours. You can follow our team's regional reports posted later today in the Winter Stormcast | Mid-Atlantic Zone on Facebook, as well as in local zones for the affected areas, including Central Virginia and the Virginia Tidewater. To sum it up, or some, tomorrow may be "just another manic Monday" in this long winter of extremes.
