FORECAST IN DETAIL
It’s another hot one, but maybe a little less hot than recently thanks to more clouds. Those clouds bring a risk of showers and storms, some of which may be strong to severe. Heat’s still oven-like tomorrow, though. Not until perhaps Sunday do we get closer to typical heat and humidity levels. Next week starts “okay,” but July heat and humidity (and shower/storm chances) are attempting to reload by midweek.
Today (Friday): A few showers could be around early this morning. Otherwise, take it slow and hydrate today with high temperatures in the near and above 90 zone, and heat indices likely to approach 100. Increased cloudiness may offer a slight break from that sun beating down. West-southwest breezes around 5 to 10 mph attempt very brief relief, but nothing super helpful. Scattered thunderstorms, some could be strong to severe with isolated damaging wind the main risk other than heavy rain and lightning, may erupt as we get deeper into the midday and afternoon. This activity should tend to be more scattered (50 percent chance overall) than super widespread, but don’t rule out the latter just yet. Confidence: Medium
Tonight: Early showers/storms remain possible (40 percent chance) but should die down relatively quickly after dark. Eastern areas could still have a couple nighttime rumbles past evening into the overnight. Most rain just wets the ground, and only a couple localized areas may see some downpours. West-southwest breezes around 5 mph may last the night. Low temperatures may hover near 80 downtown, with low-to-mid 70s probable outside of the Beltway. Confidence: Medium

Tomorrow (Saturday): We see slowly dropping humidity levels. From truly “muggy” to simply “moist” or thereabouts. A more classic summertime feeling to the air, let’s say. Not that we’ll feel refreshed or anything. High temperatures still get into the low-to-mid 90s. Perhaps near 100 if we get a perfect, perpendicular downsloping wind direction off of the Blue Ridge. West-northwest winds pick up during the day from 5 mph to around 15 mph by late morning. As the front passes in the afternoon, we have an outside (20-30 percent chance) of a shower or thunderstorm. Any could be strong given the heat and humidity, but this doesn’t look like a big severe weather set-up. Confidence: Medium
Tomorrow night: A slight 15 percent chance of a shower or storm continues through perhaps late evening. We should have slightly clearer skies than recent overnight experiences. Enjoy lower humidity riding into the region on northwesterly breezes around 5 to 10 mph. Low temperatures may not beg for open windows, but upper 60s to mid-70s (downtown) do feel a bit better. Confidence: Medium-High
A LOOK AHEAD
Sunday: It’s feeling better, but still summery with mid-80s to near 90 for highs. Skies should be mostly sunny (wear that sunscreen!). And we only have a 10 percent chance of an isolated shower or storm popping up. No need to carry that umbrella, since you should be able to dodge anything that randomly develops — it’d be brief. Confidence: Medium-High
Sunday night: Mid-60s to low 70s (downtown) looks like our likely temperature regime. Mugginess should stay under control for the most part, but it isn’t dry, crisp air by any means. Overnight A/C usage probable. Skies should have periodic clouds but some stars probably still visible. Confidence: Medium-High
Mainly sunny skies and very warm Monday and into Tuesday. High temperatures in the upper 80s to low 90s appear likely, and mugginess remains somewhat in check. Monday may end up being a bit more “comfortable summertime” weather when compared with Tuesday. Shower and thunderstorm chances Monday (25 percent chance) slowly increase into Tuesday (35 percent chance). Confidence: Medium
