It’s hard to believe that this past Friday we had cold, rainy 40s and even nearby reports of sleet. Out of nowhere, summer has seized control of our weather regime. Are your air conditioners ready? For the next several days we have humid 80s not without the outside chance of late day thunderstorm. But a potent cold front rips through the region Thursday (when will be watching a possible severe storm threat) , bringing back more seasonal 60s and 70s Friday into the weekend.
Today (Monday): Variably cloudy skies in the morning (along with an outside chance of an isolated shower), and some patchy fog in spots give way to partly sunny skies for the late morning into the afternoon. Winds from the south and southwest at 10-15 mph boost temps well into the 80s (mid-80s most spots). You’ll also notice some humidity, with dewpoints in the low 60s. Late in the day, an isolated storm is possible (20-30% chance), especially toward the mountains and in the northern suburbs. Confidence: Medium
Tonight: Any isolated storms die off, and the rest of the night is more like late June than late April. It’s partly cloudy and a bit muggy, with lows near 60 in the cooler suburbs to the upper 60s downtown. Confidence: Medium-High

Tomorrow (Tuesday): It’s a lot like Monday but with less in the way of clouds early. In fact, skies are partly to mostly sunny for much of the day. Temperatures should have little trouble reaching the mid-80s, perhaps upper 80s in some spots. Late day thunderstorm chances are bordering on the remote at 10-20%. Confidence: Medium-High
Tomorrow night: Another night with a summer-like feel. Someone, somewhere could see an evening storm but otherwise it’s partly cloudy and warm, with lows 60-67 (suburbs-city). Confidence: Medium-High
Wednesday is this week’s last day of truly summer-like weather. Before the powerful cold front arrives from the Midwest, we get one last good push of warm, humid air from the south. Highs reach the mid-to-upper 80s. We could (30% chance) see some afternoon and evening thunderstorms develop late in the afternoon, but they shouldn’t be widespead. Wednesday night, showers and thunderstorm chances increase to at least 60% west of the District and 40% or less for the District and points east. These probabilities are dependent on the timing of the front. Overnight lows are in the 60s. Confidence: Medium
Shower and thunderstorms are likely everywhere Thursday (70-80% chance), some of which may be strong or even severe. The most likely timing is from morning to mid-afternoon, but we’ll have to see how fast (or slow) the front gets here. Highs are from 70-80, but fall or remain steady behind the front. Clearing and cooler Thursday night, with lows in the 50s. Confidence: Medium
Friday through Sunday look excellent and more springlike. Cooler high pressure builds in and we should experience mainly dry, pleasant weather. Highs in the upper 60s Friday warm slightly to 75-80 by Sunday. Confidence: Medium
