Clouds have been building this afternoon and a few showers and storms have already developed in portions of Wayne, Choctaw, and Marengo counties. We will see the rain continue to overspread the area today, remaining isolated to scattered in nature, as highs climb again into the lower to middle 90s for those where the rain stays away until later in the afternoon. Heat index values are already pushing 100 degrees and will continue to climb in the afternoon.
Rain chances drop off tomorrow as most of the rain stays to our north and west associated with a very slow moving front. As we reach Sunday and Monday, rain chances will slowly increase as the front approaches and we will see rain in earnest arriving on Tuesday and lingering potentially into the first part of Thursday. As rain picks up, temperatures will be more limited in how high we reach before rain begins, so I expect that after Monday, we will remain in the 80s for highs.
Once the front clears the area late Thursday into Friday, drier and cooler air looks to filter in from the north. Now, it is too early to say how long this reprieve from the heat and humidity will last, but this cool down will no doubt be welcomed as we haven't had highs remain in the 80s in two weeks.
