Area forecast discussion, Jul 1, 12:20 PM CDT, 5 hours 38 minutes before
Area Forecast Discussion National Weather Service Jackson MS 1220 PM CDT Tue Jul 1 2025 ...New DISCUSSION... .DISCUSSION... Issued at 1219 PM CDT Tue Jul 1 2025 Rest of the Afternoon into Tonight...A trough passing to our north will continue pushing a frontal boundary south and into the forecast area through Wednesday morning. This will continue to aid in sparking showers and storms across the forecast area through the remainder of this afternoon into the overnight hours. With the unstable airmass over the CWA, coupled with some extra forcing along the front and deep-layer shear around 30 knots, the potential for isolated severe storms will continue into this evening. Damaging wind gusts will be the primary concern with such storms, with frequent lightning and heavy downpours likely. With the loss of daytime heating, convection is forecast to wane in both coverage and intensity as we approach midnight, but some isolated showers and storms can't be ruled out overnight as the front continues its southward trek. Otherwise, look for another mild night, despite some slightly drier air beginning to advect into the region in the wake of the front, as lows fall into the low and middle 70s. /19/ Wednesday through next Tuesday... The passage of a frontal boundary tonight will usher in a period of persistent dry weather through the end of the week. A drier airmass will settle over the region as northwesterly flow aloft prevails, allowing temperatures to reach the mid 90s by Friday. Rain chances will remain extremely low, with only isolated precip possible, primarily across the southern portions of the CWA, where probabilities remain less than 10%. By Saturday, moisture looks to begin to increase again, increasing the possibility for heat stress conditions. Additionally, chances for diurnal convection will gradually increase heading into early next workweek./KP/ && .AVIATION... (18Z TAFS) Issued at 1216 PM CDT Tue Jul 1 2025 Away from convection, VFR flight categories will prevail at area TAF sites through much of this forecast period. At sites where convection is observed, flight categories will fall to MVFR/IFR status due to degraded ceilings and visibilities for a brief 1-2 hour period of time. Towards day break Wednesday, some low stratus and/or patchy ground fog could again reduce categories to MVFR status briefly. West winds today will gradually become more northwesterly and northerly overnight into Wednesday in the wake of a frontal boundary sinking through the region. /19/ && .PRELIMINARY POINT TEMPS/POPS...
