Howdy!
Looking out the window (NOAA), we can see (at around 12:00 CST) there is not much of anything going on currently. Based on the NWS radar, a heat advisory is in effect for most of the region, some in effect until Thursday evening. No rain on radar for now.
The main message for today is that it is going to be hot! Very hot and humid conditions, causing heat index values to reach up to 110 for some areas. As seen below, a majority to all of the region is expected to experience above 100 degree experienced temperatures. Take care of yourself when outside!
The upper-level ridge has shifted northward, keeping the region under hot and humid conditions. This ridge will bring a shortwave over the region today as easterly flow moves in from the southern portion of the ridge, triggering a cluster of showers and thunderstorms in southern/eastern Alabama in the early afternoon, then moving westward.
This pattern will continue to trigger afternoon showers and thunderstorms for the remainder of the week. Strong mid-level flow and destabilization could support the development of strong to severe thunderstorms, main threats being strong winds and lightning.
For today, the SPC has put a good portion of the region under marginal risk for severe weather, and the rest of the region under the general thunderstorm risk. Central/southern Alabama, southern Mississippi, and parts of southeastern Louisiana have the greatest chance to see severe storms.
Tomorrow, the SPC has marked the region under the general thunderstorm risk, but these storms could still be strong. Isolated to scattered showers and thunderstorm chances continue for the rest of the week, portions of north Mississippi, Alabama, and Georgia under marginal risk for severe weather on Thursday.
