Tomorrow (Monday): The ridiculously hot conditions move off and we’re left with more normal summertime heat wave conditions.

Confidence: Medium-High

With no strong front coming through to give us a nice refreshing air mass behind it, we’re in a pretty stagnant pattern for the time being.

On Tuesday and the 4th of July (Wednesday), we’re looking at more of the same hot and steamy conditions with sunny skies and highs up into the mid-90s. Both days include the chances for storms to fire during the afternoon or evening, with Wednesday’s odds being slightly higher. Overnights remain mild and muggy, with lows in the low-to-mid 70s. Confidence: Medium-High
