As of this afternoon, there is an upper level off moving into West Virginia and a coastal low off the Delmarva Peninsula.The upper level low is going to transfer it’s some of its energy off the coast causing the coastal low to intensify. The upper level low with continue to pass through the region but not nearly as intense bringing some light snow showers/flurries through the afternoon. As it moves through, a few more light snow showers are expected in DC and west of I-95. East of I-95, areas could pick up another 0.50” – 1.00” of snow accumulation before this all said and done during the afternoon/early evening with the intensification of the coastal low. Our snow to liquid equivalent was 4:1 during this storm which means there was a lot of water in the snow—for example with a 4:1 ratio—if we had 4” of snow on the ground, then all of it melted, we would be left with 1.00” of water—a very gross wet snow which is typical in March—and pretty difficult to get good totals—but we did.
Temperatures will drop down to the freezing mark tonight so there will be some refreezing during the overnight hours and definitely some slick spots. With the exception of a few flurries floating around tomorrow, temperatures will rise into the upper 40s. The region should even experience some sunshine during the afternoon. A lot of the accumulation that was received today will melt off with the angle of the March sun.
Some breezy winds will roll through during the afternoon Tuesday. Full sunshine on Wednesday as high pressure takes charge with temperatures right around 50 degrees.
