Isolated severe storms are possible on Saturday afternoon along with very hot temps. The hot temps, and potentially additional severe storm threat will continue into Sunday before a backdoor front comes through.

This front will push through overnight into Monday bringing a stiff east breeze and significantly cooler weather by Labor Day Monday. Highs on Monday will likely only reach the low-80s with clouds and some spotty showers.
This airmass will be short-lived as we'll clear out and start to heat up again on Tuesday, but remain below 90º. Dewpoints will remain lower so the returning heat will feel a bit better.
