662 FXUS64 KSHV 252154 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 354 PM CST Tue Nov 25 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1201 PM CST Tue Nov 25 2025 - Following above normal temperatures this afternoon, a period of near to below normal temps will return Wednesday through at least early next week. - Dry conditions and low humidities are expected today through Friday, before additional soaking rains return for the upcoming holiday weekend. && .DISCUSSION... Issued at 1201 PM CST Tue Nov 25 2025 The late morning sfc analysis indicates that our weak cool front has shifted SE to along the SW LA coast into SE LA/Cntrl and Ern MS and Wrn TN. The latest visible satellite imagery indicates that the post-frontal stratocu field has begun to scatter out over much of E TX, with the drier air expected to continue mixing E into N LA this afternoon. Meanwhile, the stratocu within and along the base of the H925 trough extending from the Great Lakes into the Red River Valley of SE OK/SW AR should persist through a better part of the day today into the evening, before the closed low drifting ESE into the Midwest helps to reinforce a stronger cold front SE into the region later this evening. This secondary front will scour out the stratocu cigs that will linger, while also ushering in a much cooler and drier air mass in place Wednesday and in time for the Thanksgiving holiday. Thus, temps will return to near or slightly below the daily norms, as strong sfc ridging builds SSE from the Plains into the MS Valley. In fact, temps should fall to near or below freezing across SE OK/portions of SW AR Thanksgiving morning, and should bridge farther SE into NE LA by Friday morning as the center of the sfc ridge settles into the MS Valley. The NW flow aloft in wake of the midweek longwave trough passage remains progged to become zonal by Friday, as we await the next progressive shortwave trough that will traverse the Srn Plains Saturday. A SSWrly LLJ will develop in wake of the departing ridge and ahead of this approaching shortwave over the Srn Plains Saturday, with low level moisture quickly returning/deepening through the day. Isentropic forcing should be more than sufficient for an increase in elevated convection across the region Saturday morning, with additional forcing aloft ahead of this shortwave contributing to renewed development through the afternoon/overnight hours ahead of the attendant cold front progged to quickly shift SE through the area Saturday night. This next front should help to usher in a more prolonged period of below normal temps Sunday and into at least the first half of the new work week. There remains considerable spread amongst the various 00Z ensemble clusters in regards to the timing of another upper trough ejection early next week (at the end of the extended period), although a slower timing would result in the potential for additional soaking rains Monday and Tuesday while providing for additional drought relief. /15/ && .AVIATION... (00Z TAFS) Issued at 351 PM CST Tue Nov 25 2025 Seeing a descent cu field near and north of the I-20 Corridor late this afternoon but this should begin dissipating after sunset. WNW winds currently prevailing across most terminals with speeds at or below 10kts. A secondary cold front will push through our airspace later tonight that will allow for winds to become more NW or N with speeds increasing to near 10kts. By mid to late morning on Wed, we should begin to see some gusts upwards of 18kts or so but the pressure gradient will begin decoupling by late afternoon on Wed with northerly wind gusts subsiding. 13 && .SPOTTER INFORMATION STATEMENT... Issued at 1201 PM CST Tue Nov 25 2025 Spotter activation is not expected at this time. /15/ && .PRELIMINARY POINT TEMPS/POPS...
