Saturday will have a high of 83 degrees, and there is a chance of rain Saturday morning. Saturday will also start to be more humid and muggy by Saturday night, according to the current forecast.

The heat and humidity really make a return starting Sunday, which has a high of 92 degrees. Peak heat index values will be around 105 degrees.
