Following the record cold start, temperatures today made a commendable recovery, but failed to top the freezing mark (highs 29-32). They crash back down tonight into the teens most areas, but make a run at 40 Wednesday as sunshine makes a stronger showing and arctic air loosens its grip.

Through Tonight: Scattered clouds this evening try to clear out as the night wears on. Temperatures this evening gradually drop through the 20s in most areas. By just before dawn, low temperatures range from near 20 downtown to the high single digits in some of our cold spots. The majority of the region sees lows in the teens. There’s an outside chance Dulles Airport flirts with its record low of 7 degrees from 1978, and BWI with its record of 10 from 1873. Winds are light.

Watch out for slick spots overnight into the morning hours as any melting snow and ice will refreeze on streets and sidewalks.

Tomorrow (Wednesday): We should have more sunshine compared to today and arctic air retreats a bit. The result is a modest warm-up, with highs reaching towards 40, perhaps even into the low 40s around the District and points south and east. Calm winds become from the north late in the day at around 10 mph as a subtle cold front slips south.

SchoolCast for Wednesday (updated from 1.5 apples to two apples at 6:30 p.m.)


2 apples: Good chance of a delay outside of the District (many systems have already announced delays), some outlying areas may close (or have already closed).

1.5 apples: Slight chance of a delay in outlying school systems west and southwest of the District. Elsewhere, expect school to open on time.

Late week storm chances erode: For several days we’ve been keeping an eye on the possibility of low pressure from the south coming up the coast bringing another round of wintry weather (snow, sleet, and/or rain). Most models had just been grazing us with a little precipitation while the Canadian model suggested a bigger hit. Today’s Canadian model backed off and has joined the consensus of models pushing the storm out to sea with little to no impact. We’ll continue to watch this storm just in case it decides to make an inland move.
