 Serious heat builds back for your Sunday afternoon. A high today of 100 with mostly clear skies. At least we have a nice southwest breeze. Tonight's low down to 79. Heat advisories likely extended into our Monday and Tuesday with highs back over 100 again both afternoons. Mostly clear through Tuesday. That night into Wednesday, though, a chance of showers and storms. That comes with a cold front and a drop in highs to the 90s on Wednesday, upper 80s by Thursday.
