Upper 80s to low 90s. | Sunday: Partly cloudy, humid. Scattered showers and storms. 89-94. | A Look Ahead | Get Express Forecast by E-mail


Today (Friday): Despite haze and clouds, we still get warm and feel somewhat sticky. Most of our region should hit the mid-80s, with readings in the upper 80s pretty likely. A couple spots, mainly south of town, may get to the 90 degree mark if sun shows up for longer than expected. Breezes shouldn’t be much of a factor, remaining light and variable, along with low (10%) chances of thunder or a shower. Confidence: Medium

Tonight: Showers or isolated storms have a better chance of popping after dinner (15-25% chance) but they shouldn’t be cause for much concern. Otherwise, skies remain fairly cloudy and dewpoints rise into that muggy-feeling zone. Pre-sunrise low temperatures end up in the upper 60s in any lucky rain-cooled spots to the low-and-mid 70s elsewhere. Confidence: Medium

Tomorrow (Saturday): It may not be fully sunny, again, with a touch of that familiar—seemingly constant?—summertime haze. Temperatures head higher, into the upper 80s, if not lower 90s. I may go ahead and declare the air “tropical” and “oppressive” once again, as dewpoints likely head toward the Floridian 70-degree mark. This heightens the chance of a shower or storm to about 30%, especially in the afternoon. Slow movers may drench you, as we have seen this past week in D.C.! Anything that forms could produce a quick inch or more of rain. Confidence: Medium

Tomorrow night: Evening showers and storms could (40% chance) continue for a little while after dinner, as temperature readings ever-so-slowly fall toward near-dawn minima in the low-or-mid 70s. Confidence: Medium

Sunday: This one looks like a bit warmer than. The three-Hs: hazy, hot, humid, should once again show their faces with high temperatures getting into upper 80s and low 90s degree range. By mid-afternoon, we may want to keep an eye on the sky as thundershowers begin developing (40-50% chance). Try to tote along a small umbrella for outdoor afternoon plans. Remember to be safe! If thunder roars, head indoors. Confidence: Medium


Sunday night: Showers and storms should die out early in the evening. Region-wide, overnight low temperatures should end up in the 70s but evening plans may require undershirts or other sweat-mitigation plans, because of the humid-feeling air. Sky conditions remain somewhat murky and hazy, because of all the water vapor in the air. Confidence: Low-Medium

Monday is a continuance of our shower/storm threat along with moderate heat. High temperatures should get into the low-and-mid 90s with a 30-40% chance of a storm, especially in the afternoon and evening. It should be nice and muggy for those visiting from the Deep South … Feels like home, yes? Confidence: Low-Medium

Tuesday is a broken record, with the same storm and humidity threat. We have a good chance at getting warmer and muggier as high pressure builds more strongly into our region with highs in the 90s. Hopefully not upper 90s, but that remains on the table. Strong storms could result from the boiling atmosphere in all this heat and humidity, so we’ll have to keep a wary eye on things. Stay tuned to CWG! Confidence: Low
