Welcome to cwg.live, updated around-the-clock by Capital Weather Gang meteorologists.
Happening now: The morning is pleasant with temperatures climbing through the 70s. Afternoon highs in the mid-80s to low 90s work up a sweat.
What's next? The heat plaguing the South reaches our area Friday with highs well into the 90s for most. Weekend highs are only incrementally less hot with scattered storms possible each afternoon and evening.
Today's daily digit — 5/10: Heat and humidity are on the rise under sunny skies. | 🤚 Your call?
The digit is a somewhat subjective rating of the day's weather, on a 0-to-10 scale.
Forecast in detail
Today (Thursday): Temperatures rise steadily under sunny skies. The pop-up clouds are not rain producers but offer occasional shade as highs creep up to the mid-80s to lower 90s. Moderately high humidity (dew points in the upper 60s) is more noticeable than previous days but could be worse. The light breeze from the south is welcome. Confidence: High
Tonight: The evening is still warm with 80s not giving way until dark. Skies remain mostly clear with lows in the upper 60s to mid-70s. Confidence: High
Tomorrow (Friday): Heat peaks under sunny skies with highs mainly in the mid- to upper 90s with a possible 100-degree reading or two in hot spots. A lack of breeze and dew points creeping into the lower 70s add to the misery, with peak heat indexes of 100 to 105. A dying cool front to the north only offers a slight chance of an isolated late-day storm. Confidence: Medium-High
Tomorrow night: The heat hangs on through the evening, but lows do eventually range through the 70s. Any storms should remain isolated. Confidence: Medium-High
A look ahead
Saturday and Sunday hold more potential to set off afternoon and evening storms with locally heavy downpours possible. Highs in the upper 80s to mid-90s feel about 4 to 8 degrees warmer given the return of high humidity. Overnight readings slip into the 70s. Confidence: Medium
Sunshine is a bit more abundant on Monday and Tuesday, and showers and storms are generally isolated in nature. This allows highs to creep back into the low to mid-90s with upper 90s in the hotter spots. Enough humidity lingers to make it feel like the upper 90s to lower 100s. Confidence: Medium
Not to get hopes up too much, but the latter half of next week has fairly good model support for a more notable cooldown. Fingers crossed! Confidence: Medium
