Memorial Day: Isolated to scattered storms, otherwise partly cloudy and warm

Jared Smith / May 25, 2026 at 12:41 AM

A few more showers and thunderstorms will be possible on Memorial Day, but overall it will be a fairly decent representation of summertime. We’ll start the day in the low 70s, warming to the mid-to-upper 80s in the afternoon. Showers and thunderstorms will be most likely in the morning, propagating inland during the day. Coverage will be less than Sunday, but you’ll still want to keep an ear out for thunder, which will be your signal to head indoors as at that point, you are at risk of getting struck by lightning. However, this is no reason to cancel any outdoor plans — just make sure you’ve got a good secondary, indoor plan.
