Sunshine is nice, but this strong heat feels like too much too soon, especially when most of us trudge back to the office.

A monstrous dome of high pressure has enveloped the eastern 2/3 of the nation in a hot and humid air mass. For most of the Midwest and East, this is the hottest of the season so far, and we’re unfortunately not an exception. However, fortunately, this first-of-season heat wave is short-lived as a cold front rescues us tomorrow evening. Some heat and humidity could sneak back into the area this weekend, but at this time, it doesn’t look to rival our current super-steamy levels.

Today (Tuesday): Solid sunshine continues today as high pressure dominates, but it’s a bit like a pressure cooker as temperatures soar once more into the 90s. The persistent, stagnant air mass should outperform Monday’s levels with some areas, including DC itself seeing mid-to-upper 90s (93-98 range mainly), but humidity makes it feel like 100-105. As noted by Jason Monday, we could see some local records fall (Dulles’ 94 and BWI’s 96 could be matched or exceeded). Light breezes won’t be strong enough to offer a significant cooling effect. Confidence: High

Tonight: This hot and humid air mass is slow to cool down each evening and most spots around the area see temperatures only drop to the low-to-mid 70s. Out near Dulles and the far northwest suburbs, we could yet see some upper 60s. Mostly clear skies. Confidence: High

Tomorrow (Wednesday): Another hot day anticipated to kick off June (the start of the meteorological summer!), but we are not poised to reach the same peak temperatures due to afternoon clouds and scattered late day thunderstorms (40% chance). Highs in the low-to-mid 90s with light breezes except around thunderstorms. With all the heat and humidity around, some of these storms could be on the strong-to-severe side. Confidence: Medium-High

Tomorrow night: A 30% chance of evening thunderstorms, but then partly cloudy skies with dropping dew points. That lower humidity feels much better as low temperatures drop into the 60s (lower for outer suburbs and mid-to-upper 60s probably in the city yet). Confidence: Medium-High


Thursday and Friday are much nicer, lower-humidity days with partly to mostly sunny skies and highs mainly in the 80s. We could touch 90 in spots on Thursday, but it won’t feel like our current 90-degree weather as dew points are much more comfortable. Lows in the 60s both Thursday and Friday night with mostly clear skies. Confidence: Medium-High

Saturday and Sunday could introduce a bit more heat and humidity back into the area, but we should not get the full heat furnace effect this time as the main hot ridge resides farther south and west of Washington, DC. Upper 80s to low 90s are favored, with partly to mostly sunny skies, and a chance for a scattered thunderstorm (20% chance for now). Lows Saturday night in the 60s to low 70s due to that higher humidity. Confidence: Medium
