Scattered periods of moderate to heavy rain and an isolated gusty thunderstorm will be possible into early Thursday morning. Plan ahead for a wet start to Thursday morning.

Before 7 a.m., there is going to be rounds of scattered rain. This can slow down travel and lower visibility if you are getting an early start to the day. An isolated thunderstorm will be possible, too.

After 7 a.m., a spotty shower or isolated downpour chance will linger through mid-morning. From mid-morning through much of the afternoon, it will be dry with clouds and breaks of sun along with a warm and humid feel.

Thursday evening, another brief pop-up shower or isolated downpour cannot be ruled out, but much of the day after mid-morning will be dry.
