FORECAST IN DETAIL


For those tired of this tropical air mass that’s taken up residence here in the D.C. area, there is light at the end of the tunnel - in the form of drier and cooler air next week. Until then, we’re stuck with moderate to high humidity, highs approaching and above 90, and a daily risk of showers and storms. Sure they may be hit or miss, but when they hit they can really hit. So have the umbrella handy whether you end up needing it or not.

Today (Wednesday): The tropical air mass stays in place and so does the risk for scattered showers and thunderstorms. As we’ve seen the past few days, it’s a difficult pattern to say if or when showers or storms will form. But if they do they can be real soakers. Odds today of getting wet in any given location look to be around 60%. Highs should reach the upper 80s with partly sunny skies and, yes, plenty of humidity. Confidence: Medium

Tonight: Rain chances should drop to around 30% or lower by mid-evening as a bit drier air tries to work in. It’s still pretty muggy though with partly cloudy skies and lows mainly in the upper 60s to low 70s. Confidence: Medium-High

Tomorrow (Thursday): We should stay dry much of the day, and with mostly to partly sunny skies highs warm up to the low 90s, but with more tolerable humidity. A cold front approaches later in the day, bringing increasing mid-to-late afternoon clouds and a 30% chance of late afternoon or evening showers and storms. Confidence: Medium-High

Tomorrow night: As the cold front comes through, shower/storm chances stay up around 30% before dropping off later in the evening or overnight. Lows are still very much on the mild side - from near 70 to the mid-70s (suburbs to city). Confidence: Medium

A LOOK AHEAD

The front never really clears the area on Friday, at least that’s the way it looks now. So we’ll hold on to a 30% chance of showers and storms Friday into Friday night. The heat doesn’t want to go away either as partly sunny skies help daytime highs to near 90 to the low 90s with humidity in the moderate to high range, before overnight lows settle back to near 70 to the mid-70s. Confidence: Medium

Another cold front, this one likely accompanied by an area of low pressure, keeps the shower and storm chances going through the weekend, with the best rain chances targeting the Saturday afternoon through midday Sunday timeframe. Highs top out in the 80s with humidity holding strong until possibly decreasing later Sunday. Saturday night lows dip to the upper 60s to low 70s. Confidence: Medium
