Can't Hardly Wait?

Preliminary snowfall for the Central Mid-Atlantic until 6 PM Wednesday

5:00 AM EST 3/5/12 Are you one of those who "Can't Hardly Wait?" for the next update or for every snippet of storm news, good or bad? For powderhounds, this upcoming storm will be a dream few can envision right now. But if you're in public safety, facilities or transportation or the health care industry, it's a slow-moving nightmare. 

Either way, we know you can't hardly wait to learn there are some BIG changes to the forecast, including: 



STORM TIMING: Snowfall being observed today in our Winter Stormcast Zones from the  Western Great Lakes to the Ohio Valley will move to the Mid-Atlantic late tonight. Snow will taper to the west of PA andWV by midnight and overspread to the East by daybreak. 
  • Along I-95: A mix of rain and snow is possible before turning to all snow.
  • North & West of major cities: All snow for duration of the event
WED MORNING: Heavy precipitation rates are likely as the storm's dynamics will bring colder air in down from the upper atmosphere, while easterly winds bring in warm air off the Bay. This alignment of forces above will create a rain/snow line battle over the I-95 corridor from Philadelphia to Washington, including Baltimore City throughout the day on Wednesday. 

WED PM & EVENING: As the storm begins to transition into a more amplified coastal version,  cold air wrapping around the backside may win over warm air, and push the rain/snow line across the Chesapeake Bay. By nightfall, snow is overspreading the eastern Shore, and is heavy at times once again overnight. 
THU MORNING: Precipitation will start to pull away from the region, decreasing from west to east. Winds will remain strong from the north and northwest, exceeding 30 mph at times. 


ACCUMULATIONS: For the period 8 PM Tue to 6 PM Wed. See the map above 
Frederick County and westward: 8-14+”  NW Suburbs of Baltimore / DC: 5-10”
I-95 Corridor: 4-8” (Starting as mix)  
Southern MD/Upper Eastern Shore: 2-4” (Starting as rain) 
Mid-Eastern Shore: Coating – 2” (Mostly rain, quick burst of snow at the end) 
Lower Eastern Shore: Mainly rain
**It should be noted that it remains possible for these accumulations to be increased if short range computer model projections continue indicating heavy snow bands develop across region on Wednesday**  The latest NWS watches and warnings for the Eastern US:




IMPACTS: This is a very dynamic storm, and will have a variety of impacts. 

  • Snowfall will be of a lower ratio, around 8:1 at onset, thus heavy and wet snow is likely. 
  • There is a concern for power outages from the low ratios combined the gusty winds of 25-35 mph. 
  • Visibilities may be quite low through the event. 
  • For fans of wild weather, there may even be a chance for some thundersnow as snowfall rates could approach 2-3” per hour at times! 


This is a going to be a wild multi-day event, so buckle up and stay with your hometown weather team for authentic reports.

Is it possible for Kent and Sussex counties, in Delaware, to get more snow accumulations? Could the store get stronger?

Unknown said...

Cant wait for this one!! Been way too long since ive gotten to go out plowing.

Unknown said...

Chris wood. Everything ive seen has the potential to get stronger and is very unlikely to weaken. so there is certainly a chance for more snow.

I agree. Need an update. My son's birthday is tomorrow so we don't know if we are taking cupcakes to school or not. :)

I'm going to go out on a limb and say no. Not much has changed. Storm does appear to moving up the coast AFTER it dumps on us. So if anything, storm totals will be increased, especially if it stalls for a while as some models are indicating.

Bob Abe said...

Yes, Foots Forecast....Many of us really do want to go to this website and NOT to the Facebook page for information.

PLEASE try to update this site prior to making posts on Facebook.

..an update would be great about now. Last one we've all seen was 5AM. Then at 9am it was 'Things are still approaching and in flux.'

Thanks,
Bob

Storm said...

Frank Columbo said...

NOAA is backing off the high accumulations because there is going to be an easterly wind flow, bringing in warm ocean air.

I concur - FB is blocked at the office.
