The subtropical ridge over the Southeast is considerably weaker than it has been compared to the majority of this summer and is allowing for near or below average temperatures for the next several days. This has also allowed for a frontal boundary to move in place over the forecast region and explains the wetter weather we’ve been experiencing the last few days. This frontal boundary is expected to remain close enough to the region that it was induce wetter weather throughout this weekend and into next week.

The amount of rainfall forecasted for the southern half of the U.S. is nothing short of incredible considering how it’s expected to fall on some of the most drought-stricken states. Thankfully SE MS/SW AL isn’t currently experiencing any significant drought conditions, with only a small portion of the region experiencing abnormally dry conditions; regardless, rainfall amounts ranging from 2″-3″ can be expected throughout the next 7 days with locally higher amounts exceeding 5″ possible.

Relatively high PWAT values of 2″-2.5″ have moved into the region providing ample moisture for this morning’s showers and thunderstorms and will allow for heavy rainfall rates in the storms later this evening. These storms will generally move west to east but may cause flash flooding problems beneath any slow-moving storms. This tropical moisture is forecasted to continue allowing for heavy rainfall and higher chances of precipitation the next 7 days, keeping things cooler than normal (hooray!) but very muggy (aww).
