What about Wednesday?

What about Wednesday?

• A CLIPPER WITH MOISTURE FROM THE PACIFIC NORTHWEST REGION WILL CROSS THE OHIO VALLEY AND MID-ATLANTIC TUESDAY NIGHT INTO WEDNESDAY - NOAA WPC LOOP
• UPPER LEVEL DYNAMICS AND SURFACE CONDITIONS SUGGEST LESS IMPACT IN THE SOUTHERN I-95 CORRIDOR, BUT SNOW LIKELY FOR AREAS NORTH AND WEST OF THE COASTAL CITIES
• INTERIOR SECTIONS ALONG THE I-81 AND I-76 CORRIDORS MORE PROBABLE TO SEE ACCUMULATING SNOW. ADDITIONAL SNOW POSSIBLE FOR NORTHEASTERN STATES FOLLOWING COASTAL RE-INTENSIFICATION. 

6:30 PM EST 1/20 - Our Winter Stormcast Team has been tracking the approach of a fast-moving Alberta Clipper now entering the northern Great Lakes area today. This system is expected to impact the upper Ohio Valley tonight and cross the Mid-Atlantic on Wednesday. A timeline of effects in the eastern states:

• Overnight into Wednesday, snow will move into western Maryland and southern Pennsylvania.
• By daybreak Wednesday, expect snow showers in the I-81 to I-95 corridors, reaching the Eastern shore toward end of the morning commute. 

Forecaster Joe of our Northern West Virginia Team noted in an updated statement,  "The quick nature of this system will LIMIT snowfall totals to less than 2" for most areas in Maryland, but ANY brief heavy bursts of snow could create some slick roadways!"

SNOWFALL PROJECTIONS: Areas we expect to see the highest snow totals may be from the southern Allegheny front of southwestern PA to central PA down to the Laurel Highlands and Blue Ridge regions. Another zone of 2" or so straddling the PA/MD line is also probable. However, with the bulk of this snow falling between 8 AM and 1 PM, accumulations are more likely for grassy, untreated and shaded surfaces than main roads. 

SURPRISE POTENTIAL? If the center of Low pressure associated with this clipper tracks a few miles farther south, such as across DC instead of across northern Maryland or southern PA, snowfall rates and totals may slightly rise. Secondly, if the system travels slightly faster, bringing snowfall to the major cities before dawn, this would adversely affect the AM commute for a few hours between 5 AM and 8 AM. We'll continue monitoring the situation and report changes here and on our Facebook pages as conditions warrant.

Is winter done, or is there more?

Seasoned powderhounds frequenting this page know that despite January's usual back-and-forth weather, climate records point to an undeniable truth about what lies ahead for the Eastern U.S.

Some of our highest impact winter storms come during just one month: February.
