Destructive Late April Snow for the Appalachians
Remember the October 2011 heavy, wet snowstorm that caused millions in the Northeast to go without power for weeks? This time, locations from Jamestown New York to Bradford PA to Elkins, West Virginia could be digging out from 6 to 14″ of heavy, wet snow by Tuesday morning. I fear that elevations at or above 1500 feet will be most susceptible for a damaging, heavy, wet snow that will bring down trees and power lines.
One to two inches of steady, soaking rain will fall by late tonight across the Washington Metropolitan Area.
As the upper level low swings overhead on Monday morning, temperatures aloft will cool rapidly causing the rain showers to mix with snow, even across the far western suburbs of Washington and Baltimore. The North American Model shifted the rain-snow much further east into the Shenandoah Valley on Monday morning.
Winter Weather Advisories may be needed for the higher elevations of: The Shenandoah Valley, Skyline Drive, Loudoun County VA and Frederick County Maryland (elevations above 1500 feet) where 2 to 4″ of snow could accumulate on trees causing scattered power outages.
Highs on Monday will range from the mid 30s out west to the lower to mid 40s in DC and Baltimore. Winds will gust out of the northwest at 30 mph lowering wind chills into the 20s!
Snow Accumulation Timeline:
High temperatures in the Nation’s Capital will gradually moderate into the middle 60s by mid to late week.
