Most days will be dry, but with the high humidity, showers and thunderstorms will be possible starting on Tuesday. The threat of thunderstorms will increase through the week and there could even be some strong storms by Friday.
As far as when the heat will break – by next weekend.
Once the cold front moves through, temperatures and dew points will drop. High temperatures will climb into the low 80s on both Saturday and Sunday. Currently, it looks like a nice weekend.
Heat and humidity may return as early as next Monday. Shower and storm chances will also go up.
