D.C. area forecast: Cool with a few showers today; Heading back toward summer after

11:45 a.m. update: It’s been a cool morning with scattered showers. Mist has been fairly widespread as well. While showers have generally been waning, they’re still somewhat numerous, particularly over northern portions of the area. It appears we’ll stick with a bit higher rain odds (50%) into the afternoon than earlier thought, though most of it should be on the light side. With extra cooling from rain, highs are likely to struggle much past the low-and-mid 70s. Daily record low maximums might be in play. As far as the Nats doubleheader, it’s not clear cut there won’t be any issues, especially in game 1, but it will be refreshingly cool!

EXPRESS FORECAST

Today: Variably cloudy, showers. Upper 70s to low 80s. | Tonight: Mostly to partly cloudy. Isolated showers. Mid-60s to low 70s. | Tomorrow: Clouds generally decreasing. Shower/storm late? Mid-to-upper 80s. | A Look Ahead | Get Express Forecast by E-mail

FORECAST IN DETAIL


Yesterday was the coolest day in D.C. since the 26th of June, and it’s even possible we could end up with a high in the 70s today. Quite a turnaround compared to the scorchers of recent weeks! As long as you don’t mind a lack of pure sunshine, today’s looking like a fairly good one to spend at least some time outside. Warmth begins to return tomorrow, and when we get into the workweek, it’s going to certainly feel like summer again as heat and storm threats build.

Today (Saturday): Not the prettiest weekend day ever, but I think many will end up enjoying the break from the heat. Mostly cloudy skies and a 50%-60% chance of showers during the morning (some heavy) may try to clear a bit by afternoon, though I think the day is mainly ruled by clouds. Additional showers or t’showers are possible late day, but that looks like a pretty isolated threat, or about a 30%-40% chance. Clouds and a northeast wind around 5-10 mph help keep highs in the upper 70s and low 80s. Still pretty humid though. Confidence: Medium-High

Tonight: We’re mostly cloudy with maybe some partly cloudy intervals. Any showers (a slight chance) should focus on the early evening, with most or all of the night dry for many spots. Lows settle into the mid-60s in cooler spots to the low 70s in warm. Confidence: Medium-High

Tomorrow (Sunday): If summer days are ever “normal” this one ends up pretty close. More abundant sunshine returns, and that helps temperatures rise back into the mid-and-upper 80s. I’d lean toward the high side of that, too. There may be some p.m. storms that fire up to the northwest late, so we’ll have to watch to see if those work this way should that happen. Confidence: Medium-High

Tomorrow night: Another partly to mostly cloudy night is ahead, and the return of the south wind helps low temperatures range from the upper 60s to mid-70s. Dew points back up near 70 as well! Confidence: Medium

A LOOK AHEAD

Summer’s back on Monday, and that means heat plus humidity for all! Under partly sunny skies, it looks like we get another 90-degree plus streak going, with highs in the low-and-mid 90s. It’s pretty far out but there could be a decent rain opportunity by afternoon, the type that can produce strong or severe storms, if it stays as it looks now. Confidence: Low-Medium

We start off in the muggy 70s Tuesday morning and only go up from there. Like Monday, skies are partly cloudy and highs should reach the low-and-mid 90s. We’re still likely to be in “northwest flow” regime between high pressure south and low pressure north, so we’ll have to watch for storm chances -- timing a specific event is difficult from range. Confidence: Low-Medium
