Happening now: We get a breather today from our daily storm threat of late, and enjoy lower heat and humidity. Still, lots of sun, with highs in the mid-80s to near 90.

What’s next? This break in peak summer is only for today. 90s return with a strong to severe storm threat Sunday. Then a longer stretch of cooler conditions early next week.

Today’s daily digit — 8/10: Still warmer than it should be, but not 100 degrees like yesterday. | 🤚 Your call?
The digit is a somewhat subjective rating of the day’s weather, on a 0-to-10 scale.

Forecast in detail

Today (Saturday): Mid-80s to around 90 for highs is a good deal cooler than the last couple of days. Lowish humidity (dew points in the 50s) helps make it feel like a comparable treat. More sun than not, with light wind from the northwest. Confidence: Medium-High

Tonight: It's a pleasant evening and decent overnight as mostly clear skies persist. Humidity is sloshing back into the area, which helps keep temperatures from falling too far. Lows range across the 60s. Confidence: Medium-High

Tomorrow (Sunday): Right back to a hot and soupy air mass as low pressure passes to our northwest. Highs are near 90 or into the low 90s for most. Feeling as hot as 100 or so. Heat and humidity mixing with an approaching front means another chance of late-day storms, especially after 3 p.m., with at least an isolated threat for strong winds, hail, and even a tornado. Confidence: Medium-High

Tomorrow night: A shower or storm threat may last through late evening, with a front moving through. Humidity falls off, especially after midnight, with lows ranging from near 60 to the mid-60s. Confidence: Medium

A look ahead

Monday and Tuesday are the kind of days you might wish for on a weekend. Mostly sunny to start the workweek. Plenty of sun Tuesday, but with a small shower chance late. Highs both days look to target 80, give or take a few. Confidence: Medium

Back into the 80s on Wednesday — they don't stay away long in June. The sometimes-standard June storm chance may also make an appearance. Confidence: Medium

Hotter and more humid for Thursday. It could be the next bigger chance of storms after Sunday, with another front approaching the region. Before that, highs near 90. Confidence: Medium
