As the air turns more tropical overnight, temperatures will not be able to cool off as much. After a few nights with lows in the 50s and low 60s, tonight we'll only fall to the low 70s. Skies will remain clear, with no storms for the time being.

Heat turns more dangerous on Thursday ahead of an approaching cold front. Mostly sunny skies in the morning will help to rapidly push temperatures to around 90 degrees by lunchtime, and into the mid 90s in the afternoon. Factoring in the humidity, heat indices will climb above 100 degrees for a few hours, making for dangerous conditions. Limit time outdoors as much as possible. If you have to be outside, take frequent breaks in shady areas, and seek air conditioning if possible. Make sure to stay hydrated with water, as well.
