Thursday-Friday: Thursday’s storm chances before 5pm are relatively low for now, the trend in the timing is either evening or perhaps not until after Midnight. So check back with us on the timing details as they become clear. More rounds of storms will be possible on Friday and these rounds of storms could produce strong winds. The confidence in any severe weather is low for now, but watch for an upgrade to a First Alert Weather Day.

This Weekend: Another round or two of storms is possible this weekend and more likely on Saturday with a lower 20% chance Sunday. These storms should help suppress the temperature a little bit, but the humidity actually increases Friday into the weekend. So, it will be near normal hit and very humid with storms at times, especially Saturday.
