Seasonable Late November Weather for Mid Week
Snow Lover's Crystal Ball Makes Winter Season Debut
Matt Ross @ 9:00 AM
Last night's frontal passage only brought 0.11" of rain, but some more seasonable air will follow. Mid week will feature seasonable temperatures that will seesaw a bit, but trend colder towards the weekend - which may be a bit wintry.
Windy, Clearing. After some morning clouds, skies will clear and the sun will shine in the afternoon. It will be quite windy with gusts of 25mph+. Afternoon temperatures will hover in the mid 50s, falling to low 50s by sunset. Overnight, winds will diminish and temperatures will fall to the low to mid 30s.
Sunny, Cool. Wednesday will be sunny and seasonably cool. Expect afternoon high temperatures to be slightly below normal around 50 degrees. Wednesday night clouds will be on the increase with temperatures only falling to the mid to upper 30s.
Cloudy, Mild. Thursday will be mostly overcast and seasonably warm. Afternoon highs will be in the mid to upper 50s. A stray shower cannot be ruled out with the passage of a cold front in the afternoon. Overnight it will be much cooler with lows in the low 30s.

Snow Lover's Crystal Ball 
Next Chance of Accumulating Snow: Saturday, December 1st - Monday, December 3rd.
Probability: 20%
Potential Impact:
Commentary: Late on Saturday a potent storm system will approach from the west while cold high pressure sits to our north. Current guidance suggests a period of accumulating snow (<2") late Saturday night into Sunday before a changeover to sleet and rain for Sunday afternoon and night. As we are 5 days out, the track of the storm is still very uncertain. The storm could cut well to our west and bring us just a cool rainstorm. Also possible is a more southerly solution with a transfer of the low to the coast and thus a more wintry result. Keep in mind that despite early events in December 2002, 2003, and 2005, it is hard to get a snowstorm in early December in DC. Climatology favors a mix or rain solution. Snow Lovers should remain cautiously optimistic with the emphasis on caution. Stay tuned.
