Area Forecast Discussion National Weather Service Jackson MS 1233 PM CDT Fri Jun 27 2025 ...New DISCUSSION, AVIATION... .DISCUSSION... Issued at 1231 PM CDT Fri Jun 27 2025 Rest of Today through next Thursday...Another rinse and repeat day as a potent upper-lvl ridge continues to provide hot and humid weather to the region. Heat indices aren't expected to be greater than 105 degrees so a heat advisory isn't needed today. Diurnal showers/t-storms are expected into the evening hours. Some organized convection will be possible across southeast/eastern MS. As a result, a "Marginal" (1 out of 5) risk for severe storms will be possible across southeast and eastern MS with damaging winds being the primary hazard of concern. Over the weekend, the ridge is expected to start flatten over the southeast CONUS and a longwave trough will settle across the northern CONUS. Afternoon showers/t-storm chances will continue through the extended period as a frontal boundary is expected to stall north of the area and the airmass remains unstable. In addition to the stalled boundary, northwest flow may usher in some shortwave disturbances throughout the week. Widespread rain chances are expected (40-75% PoPs with best PoP chances east of I-55). Temperatures aren't expected to be as oppressive as dewpoint ranges in the lower 70s and highs reaching the lower 90s. Depending on cloud cover/rainfall received, heat indices could reach 105 degrees or greater and may warrant a heat advisory but that decision will be on a day by day bases. /SW/ && .AVIATION... (18Z TAFS) Issued at 1231 PM CDT Fri Jun 27 2025 Flight categories will predominately remain at VFR status through the forecast period. The potential for scattered convection is again present across the area this afternoon and early evening, along with the potential for low stratus developing at a few area TAF sites toward day break Saturday morning. If either of these are observed on station, flight categories could be reduced to MVFR/IFR status for a short duration. An isolated severe storm is also possible this afternoon, particularly across East Central and Southeast Mississippi. Damaging wind gusts will be the primary concern with the most intense storms, with frequent lightning and heavy downpours likely. Winds this afternoon will generally be from the south around 5 knots. These will subside to light to calm tonight, and will become southwesterly around 5 knots by late morning on Saturday. /19/ && .PRELIMINARY POINT TEMPS/POPS...
