Today, and the next several days, will be warm and wet with air temperatures consistently heating to 90F and heat indices peaking at or slightly above 100F. There could be relief with each day as spotty thunderstorms are projected to form nearly every day which could deliver upwards of 4″ of rain in local coastal communities.
As shown by the Weather Prediction Center, there is a large stationary front stretching from the Great Plains to the Atlantic Coast. This front is providing lift which, when combined with hot surface temperatures, can form convective thunderstorms. As a result, most of the Southeast will see several inches of rain over the next week. Along the Northern Gulf Coast, most residents will see 1.5″-to-3″ of rain but some communities could see upwards of 4″ of rain.
These repetitive afternoon showers will be a great way to find some heat relief for Northern Gulf residents. As shown in the temperature anomaly video, temperatures will wildly oscillate between above and below average for the next week. Whether or not you see heat indices higher than 100F will be determined based on local cloud coverage and the location of thunderstorms. Because the atmosphere is volatile, heat indices will be kept away from the 110s that we saw earlier in the summer. However, it will still be hot and the majority of relief that will come are those breezes that form from nearby storms.
As for the second week of August, the Midwest will likely bake in above average temperatures while residents along the Northern Gulf Coast have a 40-to-50-percent chance of above average temperatures. This pattern is predicted to unfold due to a dominate high pressure system that is slowly move from the Northwest to the Midwest. Though the system is moving eastward, it is too far north highly impact the area.
