While our leading economic indicators have been pointing way down lately, I can happily report our leading weather indicators are pointing up. After the meltdown of the past month, this is welcome news. Yes, you’ll feel more heat and humidity today, but don’t sell tonight’s cold front short. In addition to triggering afternoon and evening storms with needed rainfall revenue, the healthy dividend for the balance of the week includes lower temperatures and much lower humidity.

Today (Tuesday): Mostly cloudy and muggy, with highs in the upper 80s to low 90s. As today is my birthday (39!), this meteorologist is hoping for some lively thunderstorm fireworks this afternoon and evening to celebrate. However, the latest trends appear to be shifting the heaviest activity well to our north and east. We still have a healthy 40% chance of storms this afternoon though with winds from the southwest at 5 to 10 mph. Confidence: Medium-High

Probability: 40%
Coverage: Scattered
Most Likely Timing: 3-8 p.m.

Tonight: Evening thunderstorms could linger around the area until about 10 p.m. (40% chance), but we should get some clearing skies overnight. Lows in the upper 60s in the ‘burbs to low-to-mid 70s in the city (due to lingering mugginess yet). Confidence: Medium-High

Tomorrow (Wednesday): Change doesn’t always happen overnight, and the cold front from the night before only starts the process of scouring out our hot and humid air mass. Partly to mostly sunny skies are expected with highs still in the mid-to-upper 80s or around 90 (I worry a few spots could spike higher). However, the humidity tumbles in the afternoon, so the heat is much more tolerable. Confidence: Medium-High

Tomorrow night: Here we go. The lower dew points will allow temperatures to really start to dive under partly cloudy skies. We should see cool low 60s outside the Beltway toward upper 60s in the city under light winds. Confidence: Medium-High


Thursday is probably our best day of the week as sunny skies and cool/dry high pressure bathe our area. Highs aim for the low-to-mid 80s. Thursday night is looking quite nice with lows (get this) in the upper 50s in the suburbs to the low-to-mid 60s in the city. Confidence: Medium-High

Friday favors slightly warmer temperatures, but still in the 80s (mid-to-upper) along with partly to mostly sunny skies. Some additional clouds inch into the area Friday night with lows ranging through the 60s. And well, you might feel the humidity sneaking back into the area too. Confidence: Medium

The weekend brings back the mugginess, but not too much heat at this point. Thunderstorm chances increase by later Saturday (maybe around 40%) into especially Sunday (approaching 60%). Highs range from the mid-to-upper 80s on Saturday with higher humidity to the low-to-mid 80s on Sunday with more clouds and storms around. Saturday night could also feature some storms (40% chance) with clouds and a more humid low temperature in the upper 60s to middle 70s. Confidence: Low-Medium.
