898 FXUS64 KSHV 030024 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 624 PM CST Tue Dec 2 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1117 AM CST Tue Dec 2 2025 - Closely watching cloud coverage overnight as this will dictate the extent of the low forecast. - Brief warm-up for Wednesday, before rain cooled air drops temperatures through the end of the week. - High confidence rain prospects return Thursday, into early Friday. && .DISCUSSION... Issued at 1117 AM CST Tue Dec 2 2025 Temperatures across the region are slowly recovering from the range of 30`s early this morning. Though overnight temperatures did not fall to the cold values that guidance had suggested due to stubborn cloud coverage negating any robust radiational cooling, temperatures this afternoon remain on the cooler side in areas where those same SCT/BKN clouds remain along a sfc ridge axis. RAP 925mb RH has modeled this well as the 09z and 12z output suggest that the low level moisture supporting the low clouds, that have settled around 2kft, will continue to do so through the late afternoon. Questions arise with how the clouds impact the forecast overnight as this will determine just how cold lows are by morning. While some guidance suggests that the cloud coverage will dissipate for a few hours overnight, others remain confident that low level return flow will be strong enough to support a layer of ceilings that will inhibit any stronger radiational cooling. For now, weighing on the side of the cloud coverage locally, with an overnight forecast that has low temperatures bumped up by 2-3 deg F from the base guidance to account for the clouds overnight. While still cold, and with many near or below freezing still, these values are slightly different from the base NBM output. By Wednesday afternoon, a noticeable temperature transition will be in full swing as the aforementioned southerly wind shift, combined with some warm air advection from the west, will help temperatures rebound into the mid and upper 50`s to near 60 deg F, especially around some ETX communities. Where temperatures continue to trend on the cooler side will be across the northeast zones of the region that are still under the remaining influence of the departing surface high. By late Wed PM/Thu AM, moisture advection from the the S/SW, along with a weak surface low embedded within the mid flow of a shortwave kicking east across TX, will support high confidence in rain prospects across the region through the day on Thursday, extending into early Friday AM before the feature departs. For now, the forecast calls for a mild, and dry weekend that looks to carry into early next week. One feature that is somewhat new this afternoon is a more pronounced trough across the region for the second half of the weekend. This is an outlier in the guidance when compared to other guidance, but something to watch as this would deviate the weekend forecast from where it currently stands. KNAPP && .AVIATION... (00Z TAFS) Issued at 620 PM CST Tue Dec 2 2025 For the 03/00z TAF period...VFR conditions remain at all sites, except KELD/KMLU, where low cigs have hung around all day. There may be some brief clearing at KELD over the next few hours, but eventually low cigs will return across all sites by tomorrow morning. There is also some hint of fog development areawide around daybreak, then lifting by mid-morning. Reduced flight categories are expected to hang around through the remainder of the period, as low cigs remain in place. /20/ && .SPOTTER INFORMATION STATEMENT...
