10:10 a.m. update: Given the blanket of clouds and scattered showers, temperatures are probably going to be on the low end of our forecast today, with highs in the low to maybe mid-80s. The clouds are a stabilizing influence, so strong to severe thunderstorms are not likely. However, radar indicates on and off showers are likely into the mid-afternoon hours, perhaps tapering off after that.

Folks headed to the Mall for the March on Washington should have rain gear (no umbrellas-they are prohibited). Also, it’s very humid, so those of you spending hours outdoors should be sure to hydrate.

Summer came roaring back to life in recent days after sleeping through much of August. As the March on Washington 50th Anniversary culminates today, it’s going to be another summery one with high humidity at the least. Temps may be held back a bit compared to yesterday, but partly due to a storm risk. Other than that, there’s no serious cooling on tap, at least through the weekend.

Today (Wednesday): A batch of showers and storms to the northwest may move into the area during the morning, and the risk for at least periodic activity becomes likely by the midday into afternoon (60-70% chance at peak). It’s not a given there will be storms everywhere, but any that form could contain strong winds. Heavy rain and lightning is also a risk more generally. Coverage may end up hit or miss, but many locations should get at least a bit of rain.

Under the rainiest scenarios, highs may not get much past the 80 to mid-80s range, but should storms be less numerous, mid-80s to near 90 would do it. Winds are 5 to 10 mph from the south and southwest outside storminess. Confidence: Medium

Tonight: The shower and storm risk may totally wane prior to evening, but if not, it will as we head into the overnight — stay tuned! It remains humid and partly cloudy, with lows reaching the upper 60s to lower 70s most spots. Confidence: Medium-High

Tomorrow (Thursday): Another warm and muggy one is upon us. Skies are partly cloudy, though perhaps cloudier than not on the whole. It doesn’t look like there’s any organized storm threat, but some isolated to activity is possible (30% chance) by afternoon. Highs range from the mid-80s to near 90. Confidence: Medium-High

Tomorrow night: Our pattern is pretty stagnant, so the forecast doesn’t change too much from night-to-night or day-to-day! Partly cloudy, as lows only dip to the mid-60s or around 70 from suburbs to city center. Confidence: Medium-High


Friday should feature more partly cloudy skies and warm/hot temperatures ranging from the upper 80s to near 90. For now, it looks like any risk of storms is rather minimal, though an isolated one or two is certainly possible given the soupy air mass. Confidence: Medium

The same general story continues into the weekend, with both Saturday and Sunday facing a potential scattered shower or storm threat late in the day. Right now, it seems Sunday has the highest risk as a cold front approaches, and neither should be a wash out or anything. Both days should have highs again in the mid-80s to near 90 and overnight lows in the upper 60s and lower 70s. Confidence: Medium
