309 FXUS64 KJAN 300807 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 307 AM CDT Mon Jun 30 2025 ...New DISCUSSION... .DISCUSSION... Issued at 307 AM CDT Mon Jun 30 2025 Through Tuesday: The hot and humid pattern will persist through the early portion of the week. With PW remaining near 2 inches, daily diurnal convection will continue to be more prevalent than typical of a generic summertime day. Additionally, added forcing from a passing upper trough and approaching front may help to elevate rain chances today and tomorrow. Given the moisture-rich environment and more erratic storm motions, localized flooding can`t be ruled out each day. A few stronger storms will also be possible, especially tomorrow when there is perhaps greater potential for convective clusters to form composite outflows. Ahead of the rain each day, heat stress will be a concern as heat indices soar into the triple digits. A Heat Advisory continues today for the Delta area where heat index readings above 105F are more likely. Wednesday through the Independence Day weekend: Guidance continues to trend drier and warmer over the back half of the week as a summertime front pushes the deeper moisture south and east of the area, at least temporarily. The decrease in convection and relatively drier conditions (dewpoints will still be into the 70s most days) will allow for an upward trend in high temps, possibly pushing the upper 90s by Saturday and Sunday. As moisture begins to creep back in through the end of the forecast period, heat stress will be an increasing concern with additional advisories possible by the end of the week. /DL/ && .AVIATION... (06Z TAFS) Issued at 1254 AM CDT Mon Jun 30 2025 Brief patchy fog or low clouds will be possible through around daybreak, though confidence is not high enough to prevail at any TAF site. Scattered mainly afternoon and evening TS are expected, with brief categorical reductions and gusty wind possible. Greatest coverage is expected to be east of I-55. Otherwise, VFR conditions will prevail through the remainder of the TAF period. /DL/ && .PRELIMINARY POINT TEMPS/POPS...
