PM Update: Arctic air eases in, refreeze tonight?

Temperature Map

Temperatures: Latest D.C. area temperature map. See interactive map on our Weather Wall.

After an exciting, active 72 hours, we catch our breath with the onset of a quieter weather pattern (at least through Friday).  But this quiet weather pattern is a cold one, with temperatures well below normal.

Through Tonight: After sunset, temperatures rapidly drop towards freezing.  In our northern and western suburbs, any snow on untreated roads will re-freeze, so lookout for that and use caution. By morning, it’s very cold, with lows ranging from the low-to-mid teens in our snow-covered colder suburbs to the low-to-mid 20s in the more or less snowless downtown. Winds are from the west around 5-10 mph.

Tomorrow (Wedneday): Mostly sunny, and cold.  Highs range from near 30 in the colder north and west suburbs to the low-to-mid 30s elsewhere. Winds are from the west at around 10 mph.

SchoolCast for Wednesday (everywhere):

(1 out of 4 apples) Do your homework. You’re probably having school. Maybe a delay in Loudoun and/or Frederick County, but I doubt it.

Snowfall this season to date: With Sunday’s 0.6″ at Reagan National, and today’s 0.9″, we have 1.5″ for the month of December. Ian Livingston tells me it took until February 2 last winter to get this much snow and we’re over half way to 2.3″, the normal snowfall during the month of December.
