Through Tonight: It should be a toasty but otherwise manageable evening. Clear skies will help temperatures dip off into the low 80s and below near or after sunset. As clear conditions continue, temperatures will range across the 70s for the low. With minimal wind, from the south, some patchy fog could develop late and toward morning.

Tomorrow (Tuesday): Skies should be mainly sunny through the heart of the day. We could see some notable cloud increase by midafternoon, as showers and storms build to the west. Temperatures are expected to reach the low to mid-90s for highs. Heat indexes of 100 to 105 are possible at peak. Winds will be out of the south and southwest around 10 mph, with higher gusts.
The storm threat appears to be focused in about the 5 to 10 p.m. range, but timing could shift somewhat in closing. Given well-established heat and humidity in the region clashing with an approaching cold front, some storms seem likely. How widespread is the question. The Storm Prediction Center has the area under a Level 1 of 5 marginal risk for the region. It’s possible it could be elevated to a Level 2 of 5 on Tuesday. The main threat from storms would be isolated damaging wind, in addition to heavy rain and lightning.
