775 FXUS64 KSHV 272334 CCA AFDSHV Area Forecast Discussion...CORRECTED National Weather Service Shreveport LA 634 PM CDT Thu Mar 27 2025 ...New AVIATION... .SHORT TERM... (This evening through Friday Night) Issued at 150 PM CDT Thu Mar 27 2025 A mid-level disturbance located over the mid-TX coast continues to push north this afternoon. Radar reflectivities from KHGX, KPOE and KSHV showcase bands of light precip working north across South and Deep East Texas as dense overcast overspreads the local area. Local observations suggest that not all of this may be reaching the ground, something that will change over the next 12 hours. Convective hi-res modeling suggests that precip will continue to spread across the region as the shortwave negatively tilts overnight. Marginal forcing support is expected through the afternoon tomorrow, as modest destabilization at the surface, along with veering wind profiles may support some rotation within thunderstorms that can quickly mature. This severe threat remains rather conditional given the local parameters in play. However, it is important to remember that though the threat may be low, the wind, hail and tornado threat is non-zero. Overnight Friday into Saturday morning, the shortwave will continue pushing east, with the associated showers and stray thunderstorms following with it. The good news is that given the progressive nature of the flow, we should start to dry out through the afternoon, potentially even allowing for some sun to mix in through the mid to late afternoon. Temperatures through the period will be heavily influenced by passing precip, with highs Friday scattered through the 70`s. Lows tonight, and Friday will appear similar, ranging in the low to mid 60`s. KNAPP && .LONG TERM... (Saturday through next Wednesday) Issued at 150 PM CDT Thu Mar 27 2025 Southerly surface winds will prevail into Saturday afternoon, so high temperatures will recover for the western and central zones as the precip departs to the east. As a result, a mix of upper 70`s and low 80`s will spread across the region. Come Sunday, a broad and impressive warm sector will materialize, as gusty south- southwesterly winds between 10-15 mph look to be in place. Gusts up to 25-30 mph will be possible through the afternoon as all of this sits in advance of a robust cold front that will quickly catch up to a developing dry line across central TX. It is possible that a Wind Advisory will be needed for this time period given the potential for gusty winds through the afternoon. Ahead of the front, localized destabilization within a moisture rich environment of dew points > 60 deg F, and steepening lapse rates, will set the stage for strong to severe storms where all modes of severe weather will be possible. As the front works into the Ark- La-Tex vicinity, convective initiation along and ahead of the boundary would support the probs of severe storms. Though timing and the west and southwest extent of the severe threat remain in question, confidence is increasing in a possible mid to late afternoon event that will continue into the evening. Come sunrise Monday, the aforementioned precip should be east of the local area with some degree of weak upper level ridging working across the Plains. The post FROPA effect looks to be minimal when compared to previous passages. That being said, aside from any precip related cooling to the local temperatures, Monday for now is the "coolest" afternoon of the extended long term period. There is a signal for another frontal passage by mid-week, with the prospects for more rain in the future. KNAPP && .AVIATION... (00Z TAFS) Issued at 630 PM CDT Thu Mar 27 2025 Conditions to deteriorate across area terminals this evening as moisture translate northeast across the region. VFR ceilings to gradually lower with VCSH conditions possible areawide by daybreak Friday morning, continuing through the end of the forecast period. Otherwise, mainly southeast winds up to 6 knots expected tonight, increasing to 10 to 15 knots and gusty on Friday. /05/ && .SPOTTER INFORMATION STATEMENT...
