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.

The next seven days: A chilly and wet Saturday gives way to increasingly warm days; next front Thursday

/ at 6:54 PM

We’re taking a look at the next seven days tonight as I’ll be taking a bit of a break over the next few days. A more regular posting schedule resumes Friday!

A rain-cooled day is on tap for Saturday — not quite peak air show weather, that’s for sure — as we may challenge a record cool high temperature. The coolest high temperature on record for May 2 is 63°, set in 1978; the NWS forecast for the airport currently calls for highs to reach about 64°. It’s gonna be close! As mentioned, some much needed rain will be falling throughout the day, with some rumbles of thunder possible with some elevated instability. No severe weather is anticipated, though. It’ll be generally on and off through late afternoon before tapering off in the evening. Many of us should see an additional inch to inch and a half of rain before it’s over — quite a nice sight given the ongoing severe drought.
