A Pattern For The Powderhound In You?

PART ONE: WEATHER SUMMARY NEXT 7 DAYS
As of 2:00 PM EST THU 1/28
  • No significant winter precipitation expected in the Mid-Atlantic or Southeast through Wednesday 2/3.  A passing frontal boundary on Friday may bring occasional snow showers from central Virginia northward to central Pennsylvania;
  • A vigorous Low off the Pacific coast will move to the Four Corners on Saturday, toward the central Plains by Monday and into the Great Lakes Tuesday. See map below for 7 PM EST Sunday 1/31. View short range loop here.
  • 5 day NOAA liquid forecasts show the potential for 0.50" to 1.25" of rain is possible throughout the eastern third of the U.S. next Tue to Wed. If in areas where snow has blocked storm drains, if safely possible, it would be wise to clear the drains.



PART TWO: GHOSTS OF WINTERS PAST?

Long range indications show the next 30 days may be the 
most interesting many of us have seen in a long, long time.


Now let's compare to snowcover on January 24, 2010 as shown below.
What differences do you see? How might this affect the pattern going forward?

A Sight You Seldom See
ALTHOUGH NOT ALL ROADS LOOK THIS GOOD, 
MUCH PROGRESS IS UNDERWAY BY AN ARMY OF CREWS.

9:30 AM 1/25 - In midst of the snow recovery, we wish to take a moment and recognize road those AWESOME and HEROIC road crews: At the state level, in counties, cities, municipalities and the many many contractors large and small. They are the "stabilizer" in the recovery fuel of our region.  Need evidence? View Maryland Traffic Cameras here
FROM ALABAMA TO ALLENTOWN, thousands of snow removal workers and managers have been up 36-48 hours straight or more, with just an hour or two of sleep in between. The proof is in the powder, or lack of it, on major roadways. This storm dumped snow from Alabama to Maine! Take a look at the latest NOAA Storm Summary Report with snowfall totals. The scope, intensity and duration of this event is why it's east to call this a Historic Event. 
WHAT ABOUT MY STREET?!? Agreed. No doubt that many secondaries and many side streets still have a lot more to be cleared. But when you have 30" of snow in 24 hours, that's not a surprise. We all are human, and unless Optimus Prime and his crew are available, equipment does break occasionally. If you have the chance to safely bring a snack or drink to a road crew worker, they sure would appreciate it.
OFFICIAL NEWS: It was the snow of this life for BWI Airport, officially 29.2" as presented in this article by Baltimore Sun Reporter Scott Dance, to whom we send our thanks for including FF in the interviews. How much fell elsehwhere? Below is a preliminary estimate from NOAA:


For Maryland & Mid-Atlantic Readers
TODAY: Temps in most areas with snowcover not rising above 30 F until around 1 PM, but dropping after 5 PM. Your last good chance to get the kiddos out for sledding if you have the good fortune to be home with them. 
TONIGHT Temps hold in mid to upper 20s on south winds.
TUE 1/26 AM temps near 30 F will rise to 40 F by early afternoon. Light rain is expected from mid AM onward. We can't rule out rain arriving earlier and if so, it could easily become light freezing rain due to snowpack. We'll keep watch on it for you.
WED & BEYOND Rain from Tue is likely to refreeze in colder areas, making the AM commute still icy at times. Wednesday looks to be the most "normal" day of the week temp wise, highs in the mid to upper 30s, light NW winds and no daytime precip.
NEXT STORM? There remains some concern for a coastal system on Thursday, but updated indications as of 2 PM today show a more offshore solution. In our previous report from earlier today, we noted these points:
  • The trend with many East coast systems this winter has been for some computer models to show the storms "just offshore" a few days out. The result was a tad more onshore than originally thought. 
  • That is atmospheric variability for you, it is inexact and Earth has yet to produce a human being who can nail down exactly where a storm will be down to the mile even at 1 day out, let alone 4.
  • Snow on Thursday in the Mid-Atlantic is not a lock by far, but it is not ruled out either. The most probable call we can make at this stage is a 20-40% chance of some light snow in the eastern Mid-Atlantic to southern New England. Need some indication from others? Here is the NOAA Day 4-7 Experimental Winter Weather Outlook.
RESOURCES: You can explore this insightful suite of winter weather resources at the NOAA Weather Prediction Center in College Park, MD.
Finally, here's a sight mostly seen by those with snow.

Sunday Snowfall Rollcall!

Photo from Ms. Rochel Schnur in central MD.
5:30 AM EST 1/24 - Ready for some good news? The Blizzard Warning for many areas of the 95 corridor has been canceled! The map is no longer red, now it's down to only your toes and finger tips!  
While the adrenaline coffee is brewing, let's start the Sunday Snowfall Rollcall! Let us know: 

1)   How much; 
2)   Location; 
3) How long you think it will take to clear that walkway/driveway/lot?

Remember the road crews and lot workers. Some have been on this straight since Friday afternoon with a few hours sleep if any at all. Consider offering them something-- cocoa, bottled water, a snack, or the most meaningful thing right now: Appreciation.

The Snow of your Life


4:30 AM EST 1/23 Winter Hurricane? Snow-nado? What's your one or two words to describe the scene outside?

One of the wildest radar reflectivities we've ever seen from earlier this morning shows the incredible intensity of this Big... er, ULTRA Kahuna now ripping across the region.

Believe it or not, snow rates and wind speeds may continue INCREASING the next few hours by daybreak, making 2010 seem Iike a flurry compared to the amazing strength of this storm. After sunrise, get ready to cue the thundersnow if you live anywhere east of I-81.


Tell us about the monster at work at your house, or you can share your pics to our Facebook page where there are a "few' readers. Just take it that photo safely from the window of course!)

THE COLORS ABOVE? The red/green in that top image shows how high a velocity the energy is moving toward and away from the Sterling NWS radar site, simultaneously. It's also something you normally see in tornadic radars, not snowstorms! There is no such thing as a snow-nado but in Hollywood that's what they would call it. Here in Maryland, they just call it normal-- about every 6 years or so.

"Where you stand depends on where you sit."
  • CHANGES COMING: First of several fast-moving cold fronts sweep in Sunday then Tuesday, ushering in a sharp temperature drop for the Mid-Atlantic into next Friday.
  • NEXT STORM? Computer models beginning to show a potentially significant coastal event for Friday 1/22 into Saturday 1/23. The map below pertains to a southern coastal on Sunday 1/17 to remain south of the Mid-Atlantic. 



7:00 AM EST 1/17 - Big Changes On The Way This Week:

1) The first of several fast-moving cold fronts sweep through on Sunday then Tuesday, ushering in sharp temperature drop for the entire region through next Thursday.

2) Sunday night may feature passing snow squalls that could douse us with a dusting, especially for areas bordering the Chesapeake Bay and the Eastern Shore.

3) Overnight into Monday, Arctic High pressure takes control. Highs by Monday don't break 25 F, with AM lows in the teens through Wednesday. Toss in winds of 25 mph for a day and a half, it'll feel like a real-life version of a Shakespearean quote about the ilk of a nasty winter's vengeance.

4) The Next Storm? Computer models project rising potential for a coastal winter weather event starting next Friday 1/22.  What we can say thus far is guided by current long range indicators, depending on where you sit - may be a bonus or a bane. Details below:

A Promise of Future Powder?

Improving Opportunity For Accumulating Snow Late Next Week

Fluffs of cloud-like snow on a wood grained "sky"
Photo by central Maryland reader Jeff Perkins
6:24 AM 1/14 - If you managed to capture falling fractals Tuesday night (or any other time), we welcome your photos for future posts. 

What's interesting to note in the photo is how the snowflakes have a fair amount of fluff and substance, not tiny ice crystals. 

It's an indication that despite dry air and marginal moisture, the right ingredients assembled in this brief time period to produce a snow type that can clump together, aiding in accumulation.


Photos may be submitted via a post on the Facebook forecast page for central Maryland or by email to team@footsforecast.org.

  • TODAY - Sunrise temps in the mid 20s across the area will be cooled by winds of 10 mph at times, but at least highs will climb to the low and mid 40s across the region. 
  • FRIDAY into SUNDAY - The pattern that can't win for losing looks to score another win for someone else. A cold rain arrives late Friday and continues into Sunday. Some areas of northwest Maryland and central PA could see gloppy wet snow, but us metro dwellers will have to contend with just cold and damp.

  • NEXT WEEK - Passage of the weekend system will usher in below normal temperatures once again. An Arctic front arrives on Sunday, bringing very cold conditions for Monday through Thursday. The next best opportunity for accumulating snow in the Mid-Atlantic comes Thursday night 1/21 into Friday 1/22. Updated details on this rising potential will be issued in today's Weekly Insider. To become a subscriber and be in the know before the snow, preview the advantages at our Insider's registry page. 


Hope ahead for wintry wonderers. Take note that each passing event has been bringing the long range pattern into closer alignment for a significant coastal event. This may just have to be a case of "good things come to those who can wait."

The winds of Winter hasten their return.


4:30 PM MON 1/11 - Surely you felt the vengeance of that wicked wind from Sunday night. By the time you read this, those sword-freezing wisps of cold will be hastening their return to the land on Tuesday. 
This front of cold heralds arrival of another major turning point in our seasonal plot toward a stormy pattern ahead.

TUESDAY into WEDNESDAY 
A clipper crosses through on Tuesday in daytime, granting the Night Watch a reprieve. Rumors of snow on this day to befall the region may come true, albeit not enough to satisfy eager young lads and lasses seeking a respite from the books (or we gather, their masters.) 
  • Still, squalls of snow are expected before twilight on Tuesday, which may confound evening travelers from central Pennsylvania on south to the DC metro region.
  • Winds expected to gust above 30 mph at times Tuesday night into Wednesday

BEYOND THE WALL - Chill continues to grip the land for nights ahead, and before long the spectre of new storms brewing from afar may challenge the plans of many. Fear not, fellow Powderhounds, we are certain this winter will bring more than dry harsh weather and trees without leaves. If you are not afraid of what lies beyond the Wall, we will relay the foreknowledge in due time.

"I can be as contrary as I want..."
-Lady Violet Crawley, Countess Dowager of Grantham in Downton Abbey
(clean Video highlights of Lady Violet's linguistic moments)


6:00 AM 1/7 - For Downton Abbey watchers, we cannot help but see a bit of Lady Grantham in the recent doings of Mother Nature. Surely you would not jest.

Consider how stoic and uncooperative she has been of late: In two weeks, those of us in the Mid-Atlantic will have seen a temperature transference from the 70s on Christmas Day, with occasional tropical deluges at times, to recent readings in the New Year uncomfortably close to the calendar date (such as near 10 F in parts of Frederick County Tue AM). 

If you seek temperature consistency to avoid the colds and flus that follow such Yo-Yo weather, we agree it is quite the horrid and contrarian pattern in present times. Is there any hope for stability? 

THE WEEKEND & AFTER
  • Temperatures Thursday into Sunday climb from the 40s for most into the mid 50s and perhaps 60 F along the coast. This mild surge will of course be accompanied by rain, and lots of it, arriving Friday afternoon continuing into Sunday.

  • The roller ride resumes early next week, with an Arctic front crossing Sunday afternoon, dropping temperatures 25 degrees or more to the low 30s by Monday morning. Then overnight lows return to their proper place in the 20s. 

ALAS, DEAR POWDERHOUNDS, we know your heart pumps more than just blood.
If snow is what you seek, the truth of the matter is you will have to remain patient a scant longer for it, unfortunately. 

Soon follow is a report for outlining the types of storm and conditions required to deliver the powder of your pleasure. We call it "the Four C's of Real Snow" for the Mid-Atlantic. 
Do check back today for the next part, it will be an important guide to resolving uncertainty on when the pattern can make good on it's winter promise.

Winter's Chill Strikes Back
  • Northwest flow today of 10 mph will keep conditions feeling much colder;
  • AM lows Tue-Thu in the teens region-wide, daytime highs 30-35 F most areas;
  • Rain approaching the DC-Baltimore-northern Virginia region Friday may start as light freezing precip early Friday morning, before turning to all rain. 
  • A pattern change toward more stormy conditions is in the offing after this weekend, with factors becoming more favorable for snow next week.

"Oh the times, they are a-changing." - Bob Dylan

8:00 AM EST 1/1 - As we ring in the New Year, eastern U.S. weather watchers know big changes in the pattern are looming on the horizon. A new change this month will be the option to access our reports through custom apps for clients, Insiders and readers alike.

For now, if you enjoyed the BBQ-like weather featured at Thanksgiving and Christmas in the east, but are ready for a return to cold, your wish is about to be granted. 

Although snow cover in Canada and across the northern U.S. has severely hampered winter-dependent industries, long range indications show a series of Arctic Highs will begin moving southward in the next 2 weeks. These initial Highs will usher in seasonal temperatures, and for those yearning to see snow on slopes or streets, reintroduce one of several critical pre-requisites for accumulation: Frozen ground surfaces. 

Want Snow? First, Freeze The Surface. Given the long period of above-normal temperatures, this process will take many overnights of sub-32 F conditions to refreeze the ground. 
  • However, the U.S. Hazards Map from the NOAA Climate Prediction Center as shown above indicate the pattern is reaching a crucial turning point for winter.
  • Once snow cover can appreciably build in traditional regions such as the Great Lakes regions, southern Ontario, Pennsylvania, New York and New England.
  • Consistent snow cover increases capacity of Arctic Highs to position for longer periods of time in "storm-favorable" locations. 
As the old-school meteorologist saying goes, "Predict the High and you predict the storm." Yet, some need more details than that, and it's time for new options.

This Year, Advance Your Access To Our Reports: 
Become an Insider

As technology increases the pace of life, we know readers wish to retain authentic connections to reliable, uncomplicated information.

Ever notice when automated apps couldn't portray rapid weather changes? Many times, the careful analysis you need only trained human eyes can deliver. 

If you have trusted us all these years to do just that, we recommend gently advancing your access to the next level. 


New World Problem, Authentic Solution. We offer a resource that retains your connection to real forecasters seeing the same weather you are. Automated data is a useful resource, but programs that operate your apps don't permit the level of customization that's central to our approach. As an Insider, you're being advised by real people who can interpret what's coming in a way computers were not designed to do.

We cordially invite you to join the many readers who are Insiders with us. Read further to see if this service would be of value to you.
