Sunday: Heat, humidity, and afternoon storms

/ August 15, 2026 at 11:21 PM

Extreme Heat Warnings look to take a break on Sunday, but that is little solace with heat indices expected to continue to peak into the lower 110s in the afternoon, well into Heat Advisory criteria. Scattered showers and thunderstorms should develop again in the afternoon along the seabreeze, and a few of those could be on the strong side given plenty of instability once again. We’ll also see a risk for flooding, especially where storms train in the same areas, courtesy of a well-saturated atmosphere. Be ready for conditions to change quickly, particularly after 3-4 PM.
