Temperatures took a nose dive today, with highs temperatures over 30 degrees colder than yesterday. The wind, which gusted at 30 mph or higher for 21 straight hours at Dulles, is finally easing some. After a very cold overnight period, temperatures mount a solid recovery Friday, heading up to near 60 degrees. What a weather see-saw!
Through Tonight: Mostly clear and very cold. Lows range from the upper teens in the colder suburbs to mid-20s downtown. Winds at 10-20 mph this evening drop to 5-10 mph towards morning. Wind chills are in the teens and low 20s for the balance of the night.
Tomorrow (Friday): It’s cold when you get up and head out and even into midday. But you’ll notice the sun taking an edge of the chill in the afternoon, with highs in the mid-50s to near 60. Unfortunately, a wind from the south kicks up at 10-20 mph, with some gusts in the 20-30 mph range, taking a bit of the enjoyment away from the moderating temperatures.
Pollen: Writes Susan Kosisky, director of the U.S. Army Centralized Allergen Extract Lab: “Some rain yesterday probably diminished the count somewhat, as did the colder weather that moved in overnight. Our tree count was still HIGH however, at 206.71 grains/cubic meter.”
