FORECAST IN DETAIL

Our early summer heat wave peaks today and tomorrow, with high temperatures flirting with record levels. By Wednesday, a cool front slips into the area, taking an edge off the heat and igniting some storms. Temperatures are closer to normal for the second half of the week, but we’ll have frequent shower and storm chances.

Today (Monday): The sun beats down, the air is thick, and it’s simply uncomfortable out there. Highs surge into the low-to-mid 90s, putting Reagan National’s record high of 95 degrees in jeopardy. It’s moderately humid too (dew points mid-to-upper 60s), making it feel a few degrees hotter. There’s not much of a breeze to take an edge off the heat, unfortunately. Confidence: Medium-High

Tonight: It’s a muggy evening with temperatures only slowly falling back into the 80s. Overnight lows struggle to drop below 70 in the suburbs and 75 downtown. Lights winds. Confidence: Medium-High

Tomorrow (Tuesday): Just like Monday, it’s hazy, hot and humid. This may be the hottest day of the week, with many locations soaring into the mid-90s. Reagan National’s record high for the date of 96 is reachable. Late in the day, we could see an isolated storm — best odds in our western areas. Confidence: Medium-High

Tomorrow night: Partly cloudy and continuing warm and muggy, with lows 70-75. Confidence: Medium-High

A LOOK AHEAD

A cold front slips into the region from the north on Wednesday, bringing in increasing clouds and a pretty good chance of showers and storms in the afternoon. Before storms break out, it’s still quite warm and humid, with highs in the 85-90 range. Storms end in the evening, with partly to mostly cloudy skies overnight and lows in the 60s. Confidence: Medium

It’s noticeably cooler on Thursday as winds come in from the northeast. While I can’t totally rule out a shower, most of the area is dry most of the day — despite considerable clouds. Highs are in the 70s to near 80. Overnight, skies are mostly cloudy with lows in the 60s. Confidence: Medium

A warm front may try to push north through the region on Friday, helping temperatures pop back into the 80s, although there’s some question how far north the front reaches. If it remains to our south, we’ll remain in the cooler, cloudier air, with highs in the 70s. With this front nearby, some showers and storms are possible, mainly in the afternoon-evening. Confidence: Low-Medium

Over the weekend, we should be squarely back into a warm and humid weather regime. Both days should have partly sunny skies, but the chance of late day showers and storms. Highs are in the 80s (maybe near/above 90 Sunday) and lows are mostly in the 60s to near 70. Confidence: Low-Medium
