D.C.’s getting well into its warmest period, with the average high at 89 degrees from July 7th through the 22nd. We should not expect much in the way of cooling, even behind a cold front like the one that passed through yesterday. Instead, with the return of sunshine, today is probably warmer for most folks and that’s a trend we continue with into early week. But as has been the story this summer, at least compared to last, the 90+ heat doesn’t like to stay too long before a break, and another front looks to usher one in after Tuesday.

Today (Saturday): There could still be some clouds around in the morning as the front that doused many yesterday continues to head south and east away from the area. Still, this might be categorized a mostly sunny day given the likely lack of clouds during the afternoon and evening. Highs reach the upper 80s to near 90, and unfortunately, it’s still pretty sticky, but perhaps a bit less so than recently thanks to a light north or northwest wind. Confidence: Medium-High

Tonight: It’s mostly clear and fairly pleasant. Evening temperatures falling toward the 70s eventually reach the mid-to-upper 60s in the suburbs to about the low 70s downtown. It may not be widespread, but watch for a touch of fog in the usual spots late at night or early in the a.m. as winds go near calm with temperatures nearing the dew point. Confidence: High

Tomorrow (Sunday): Another mostly sunny day is ahead, this time with a bit more heat. Highs should have little trouble heading toward the 90 and into the low 90s — perhaps a touch higher in the urban centers or southern parts of the area. There could be a late-day storm tantalizingly close in the hills to the west, but the odds of us getting in on the action are not great (10%?). Winds are light, but probably flip back to coming from the south late. Confidence: High

Tomorrow night: Under the influence of a strong high pressure over the south-central U.S., we’re still largely clear. It’s also pretty warm, which should be expected in mid-July. The return of the south wind also sends humidity back up. Lows dip to near 70 in the suburbs to about the mid-70s downtown. Confidence: Medium-High


On Monday the high pressure system is still in pretty solid control. However, we may see a bit more in the way of cloudiness, so let’s call it partly to mostly sunny. Highs should reach the low-to-mid 90s. Odds are still not that good for a late-day thunderstorm, but better than Sunday – about 20-30%. Confidence: Medium-High

By Tuesday it seems a weak cold front will make a run at us. Depending on its timing, this could end up the hottest day of the stretch thanks to pre-frontal warming. Right now I’d lean toward highs in the mid-90s or maybe even higher, but if clouds come in early that could be held back closer to 90 or the low 90s. The front runs into plenty of heat and humidity, so showers and storms look to threaten late day. Since it’s still pretty far out there, I’ll say about a 50% chance. Confidence: Medium
