Rest of the work week: Periods of more thunderstorms

/ June 10, 2025 at 6:11 PM

Thunderstorms will continue to feature prominently in the forecast as we head into the second half of the work week as warm and humid conditions continue. Temperatures will generally run pretty steady-state, right around normal for this point in the year with lows in the low 70s warming to the upper 80s each afternoon, with some moderation in temperatures expected at times thanks to thunderstorms. It won’t rain all the time as the best chances for storms will arrive each afternoon, though a stray storm or two can’t be ruled out at any point.

The risk for organized severe weather will decrease heading into the second half of the work week as high pressure ridges in aloft. Still, colliding outflow boundaries and storms interacting with the seabreeze can help produce short-lived, localized severe weather. Be sure you’re listening for weather warnings as you head out and about, just in case.
