Weekend forecast: Stormy Saturday, quieter Sunday

/ April 25, 2025 at 9:56 PM

A front slowly approaches the area during the day Saturday, and ahead of it we’ll see scattered showers and thunderstorms begin to develop during the afternoon as the inland-moving seabreeze combines with some mid-level energy aloft. Some brief heavy rain is possible but shouldn’t ultimately amount to a ton of rain in any one location. Temperatures will continue to run above normal for late April; expect lows in the mid-60s to warm to the mid-80s in the afternoon before storms kick in.

The front gets by on Sunday, and winds shift a little more northeasterly as a result. We’ll start in the mid-60s once again, but temperatures should peak a touch cooler than they did on Saturday, with highs in the low 80s under partly cloudy to mostly sunny skies. Quiet weather continues for a few more days, with temperatures warming back into the mid-to-upper 80s by the middle of next week.

Thursday: A couple storms possible, otherwise partly cloudy

/ at 6:09 PM

A few more storms will be possible Thursday as the lingering stalled front hangs around a bit longer. This, combined with the seabreeze, keeps a slight chance for storms in the metro in play for a good bit of the day, though the rain chance should diminish as the seabreeze pushes further inland. Temperatures will still be on the warm side of normal, but cloud cover, storms, and onshore flow should keep highs suppressed to the low 80s.
