More heat and humidity is on tap for Wednesday. Afternoon temperatures will climb to 85 on the beaches and 90 inland. With high humidity in place, a few showers or storms will be possible but rain chances are only 20%.

Thursday will see a similar weather pattern with a 20% chance of a stray shower or storm and temperatures in the 80s to near 90. The heat index will climb into the upper 90s by the afternoon.

A much more active weather pattern develops by Friday as very high humidity meets up with a slow moving cold front. The result will be a good chance of storms through the late afternoon and evening. With plenty of heat and humidity in place along with the front to add a spark, some of the storms could be strong with locally heavy rain and dangerous lightning at times. Before the storms arrive, temperatures will return to the middle and upper 80s.

The front will still be in the area on Saturday and keep a 40% chance of pop up showers and storms through the day.

By the 4th of July, the front will push off shore allowing lower humidity to push into the area and result in lower rain chances. Right now the forecast for Sunday indicates increasing sunshine and temperatures in the middle 80s with just a 20% chance of a stray shower or storm.
