Our work week finale has been pleasant enough, with falling humidity and afternoon highs in the mid-to-upper 80s. The weekend, generally, looks good, though I worry about the possibility of showers Saturday. Of the two days, Sunday – for sure – is the safe pick for outdoor plans.
Through Tonight: It’s very, very nice this evening. Temperatures fall back through the 80s and into the 70s with low-to-moderate humidity levels (dew points near 60). Skies are mostly clear, though high clouds may arrive around morning, with lows in the low 60s in the cooler suburbs to the upper 60s downtown. Light winds.
Tomorrow (Saturday): The morning hours are mostly dry, as temperatures climb through the 70s. But we’ll see an increase in clouds as a cold front sinks south from the north. Areas west and northwest of the District have a 20-30 percent chance of showers by noon. During the afternoon, as temperatures rise into the low and mid-80s, there’s roughly a 50-50 chance of showers throughout the region. If you have plans to be outdoors you might be fine, you might not… so keep an eye on radar. Showers that develop should be scattered and intermittent. Winds are from the west around 5-10 mph.
Saturday night: There’s a good chance of showers (maybe a rumble too) Saturday evening (60 percent) but they’ll tend to be episodic and scattered – so not a washout. They should begin to clear by dark, with overnight lows mostly in the 60s to near 70 (downtown). Light winds.
Sunday: Becoming mostly sunny, breezy, less humid and delightful. Highs reach the low-to-mid 80s with winds from the northwest at 10-20 mph.
Pollen: Grasses, trees and weeds are LOW; mold spores are HIGH
Bit by bit, D.C.’s losing daylight: It’s a somewhat depressing thought: over the course of August, Washington, D.C. loses 1 hour and 7 minutes of daylight. By August 31, the sun rises at 6:36 a.m. and sets at 7:39, compared to 6:09 a.m. and 8:19 p.m. for sunrise and sunset on August 1.
