The subtropical ridge/areas of high pressure are holding on to the region today keeping things a bit warmer and drier; however, the upper-level trough in the Northeast has made room for more disturbances/storm systems to make their way southward into the forecast region. Come Thursday and Friday things become more active as upper-level energy swings through and brings thunderstorms and heavy rainfall.

Significantly high PWAT values ranging from 2″-2.25″ will have arrived by Thursday and will remain in the area into Friday as the front stalls just north of the region. This abundant moisture will allow for intense downpours as the upper-level swings through the region causing widespread showers and thunderstorms. Surface moisture will also remain high with dewpoints ranging from 70F-to-75F; however, temperatures will be slightly cooler both Thursday and Friday, giving us a break from heat.

Overall, parts of the Southeast (including SE MS/SW AL) will see plenty of rainfall and below-average temperatures this week. Widespread totals ranging from 2″-4″ will be seen across the forecast region, with some of this rainfall occurring in quick and intense downpours leading to flash flooding, so be sure to avoid flooded roadways. I hope you get to enjoy your week and if you hear thunder outdoors, seek shelter indoors!
