PM Update: Autumn makes a comeback; today’s rain totals

Temperature Map

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

The cold front responsible for today’s weather excitement is pushing off the coast, leaving much cooler and more seasonable air in its wake. Instead of an umbrella, you may want to grab a layer or two heading out this evening. Early evening temperatures are a good 20-25+ degrees cooler than yesterday!

Through Tonight: After the last few sprinkles depart shortly, clearing works through the area through the rest of the evening, and we end up mostly clear overnight. It’s a much cooler evening than we’ve seen lately, no doubt! Lows eventually reach the mid-40s to lower 50s, suburbs to city. Winds are from the northwest around 5-10 mph with higher gusts.

Tomorrow (Tuesday): Following all those warm and muggy days the first week of the month, tomorrow’s one we’ve been hoping for. Mostly sunny skies and a breeze from the north/northwest combine to create a spectacular day. Highs reach the upper 60s to low 70s.

Today’s rain: As of 5 p.m., rainfall totals at the main reporting stations are all near 1″ from today’s rainfall. Reagan National and Dulles both received 1.13″ of rain, while BWI picked up 0.84″. Radar estimates more or less match up with these readings, indicating that between 0.5″ and 1.5″ was most common across the area. Heaviest totals generally aligned themselves over western suburbs and along I-95.

Pollen update: Before rain washed the air clean today, tree and weed pollen was low, and grass pollen moderate. Mold spores have been running moderate/high.
