The week ahead: Unsettled to start, but summer-ish this weekend

/ May 10, 2026 at 10:19 PM

I hope all of you out there who celebrated Mother’s Day today had a wonderful day. It ended up being a pretty good weekend weather-wise, with much of the moisture staying suppressed to the south. Monday, however, will bring more substantial rain chances as a cold front pushes south and eastward. We should stay quiet through the morning, though by early afternoon we should start to see showers and a few thunderstorms develop, first along the seabreeze and then becoming more widespread as the front moves by later in the day into the evening. There’s a risk for one or two thunderstorms to become severe, with damaging wind gusts the main concern, though widespread severe weather is not expected. We could see some brief periods of heavy rain, but with relatively quick storm motions expected, they won’t be hanging around long enough to cause any flooding issues. Temperatures will run on the warm side of normal for mid-May, with highs potentially reaching the upper 80s before thunderstorms kick in.
