DISCUSSION
Issued at 1204 AM CDT Wed Jul 9 2025

Moist boundary layer advection from the Gulf will continue across the southeast CONUS tomorrow morning. This will allow for widespread coverage of scattered showers and storms through tomorrow afternoon.
Similar to yesterday, a few strong thunderstorms cannot be ruled out. Humid conditions will persist, but highs will be a touch lower as they range from the upper 80s to the middle 90s. This is due to a better coverage of convection in the afternoon. Therefore, heat index values will be held more in-check, but toasty nonetheless.

Thursday through Friday will see higher coverage in showers and storms. This will allow for daytime highs to remain near seasonable levels. Dewpoints will still remain high in the mid to upper 70s with the hottest timeframe being mid morning to mid afternoon each day before isolated showers/storms begin.

Global guidance is still showing a trough axis over the Mid Tennessee Valley dropping southward across northern MS heading into the late week. This combined with daily diurnal convection, favorable lapse rates and westerly flow could allow for some strong to isolated severe storms to occur. Forecast confidence is still low at this time regarding the timing and intensity of this system given the inconsistency between model guidance. More information will become available as we get closer to the late week. Storm chances will continue across our CWA through the weekend. Heat will make a return across the area Friday through Sunday. With dewpoints forecasted to peak in mid to high 70s and highs in the 90s, areas along and west of I-55 will have the potential to reach heat index readings between 105-109. Heat headlines and advisories may be needed as we get closer to the weekend.

The GFS guidance is continuing to highlight a 1016-1020mb sfc high over the eastern Gulf. To the west of this high, southerly moist boundary layer advection is expected to continue across our CWA looking ahead into early next week Monday. This should allow for scattered showers/t-storms to persist across the area with slightly higher rain chances across the Pine Belt. Rain chances will continue across the area heading into Tuesday.

Looking beyond the extended period, future guidance is showing afternoon highs peaking in the mid 90s areawide. This combined with dewpoints in the low/mid 70s along with humid conditions will likely result in heat indices between 105-110 degrees. Heat trends will continue be monitored as we get closer to the early to middle of next week and heat headlines may eventually be needed as well.

It appears some merging outflow boundaries will help convective activity linger a bit longer this evening over the JAN/HKS area, but confidence in impact is low. Otherwise, persistence will be a good forecast with VFR conditions and light surface wind overall, along with the potential for brief impacts from diurnally driven isolated TSRA and shallow early morning fog. /EC/
