FORECAST

TODAY

Sunday will be noticeably quieter than Saturday, with only a 20% chance of an isolated afternoon shower or thunderstorm. Most locations will stay dry as temperatures climb into the lower 90s with high humidity. Weak upper-level flow will limit storm development, resulting in much lower rain coverage than the previous day.

The best chance of rain arrives Monday night through Wednesday, when deep tropical moisture will support periods of locally heavy rainfall. Some storms could produce intense downpours capable of causing minor flooding, especially in low-lying and poor drainage areas. While it’s still too early to determine exactly where the heaviest rain will fall, Tuesday and Wednesday currently appear to have the best potential for widespread coverage.

REST OF THE WEEK

Cloud cover and frequent rain will also keep temperatures below seasonal averages through the middle of the week, with some communities remaining below 90 degrees Tuesday through Thursday. Rain chances begin to decrease late Thursday, with drier weather expected to return by the end of the week.
