We start off mostly clear, outside of a little patchy fog around daybreak, for our Wednesday morning. Temperatures begin in the low to mid 70s. By the afternoon, with daytime heating, we look to see a few scattered showers and thunderstorms. There may be a slightly better chance of them over southern middle Tennessee versus north Alabama, but there’s the chance of a few afternoon storms areawide. By early evening, we lose daytime heating, and any thunderstorm development fades away. Partly cloudy skies are expected Wednesday night with temperatures getting down to the mid 70s.
Temperatures will be a bit on the “pay attention” side of hot for Wednesday as daytime highs reach the mid 90s. Combined with dewpoints up into the 70s, that will lead to heat index values by the afternoon of 103 to 108 degrees, and a Heat Advisory is in place for Wednesday over north Alabama, but heat index values may end up being just as high over southern Tennessee as well.
Scattered showers and thunderstorms continue for our Thursday and Friday, before becoming more numerous on Saturday as a deeper plume of moisture comes north into the Southeast. Some of that rainfall looks to be locally heavy at times, but it won’t be an all day washout. Scattered showers and storms will still be around by Sunday before becoming more isolated going into next week as an upper-level ridge of high pressure intensifies with time across the area.
In the tropics, we are watching the disturbance moving across the northern Florida peninsula toward the northeastern Gulf. The National Hurricane Center currently gives this a 40% chance of becoming a tropical depression. However, it is looking more like the center of circulation is likely going to track too close to shore for any chance of significant development. The main issues along the Gulf Coast will be off and on rounds of heavy rain and storms through the rest of the week and into the weekend, along with an increased risk of rip currents across the northern Gulf Coast.
