Through Tonight: Skies remain partly cloudy into the evening, but we should trend cloudier into the night. There could be a shower or even a rumble in the predawn period. For now, it seems that activity should want to focus to the south of our area. Humidity levels are up, and air that’s moist has trouble cooling off. As such, lows are mainly in the 62-to-68-degree range.
Tomorrow (Friday): Behind a weak cold front, the morning features clearing skies and lower humidity. It doesn’t last long, though. Winds turn back to the south as the day progresses, and it’s much like today in the end. Highs reach the low and mid-80s. Winds are variable, but switching to the south around 5 to 10 mph.
Pollen update: Tree pollen is HIGH at 182.43 grains/cubic meter. Mold spores are low/moderate. Other pollen types are low.
Weekend heat: It’s still looking like we get our first real taste of summer this weekend. Whether it lasts both days is another question. While there’s some indication that it could, there are also hints that Sunday will be only above normal instead of way above normal. The NWS forecast calls for 91 in D.C. on Saturday. If we make it to 90, it’ll be the earliest since 2013, when we got there April 10.
Perhaps more impressive are the possible overnight lows. Both Saturday morning and Sunday morning could threaten to feature lows of 70 or higher in the city. Should that happen, it would be the earliest on record for a low of 70 or above, besting 2010’s first on May 2.
