684 FXUS64 KLUB 262007 AFDLUB Area Forecast Discussion National Weather Service Lubbock TX 207 PM CST Tue Nov 26 2024 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 201 PM CST Tue Nov 26 2024 - Low-end windy conditions are expected on Wednesday across the Caprock, with a cold front moving through during the afternoon. - Snow flurries and sprinkles are forecast across portions of the far southern Texas Panhandle and South Plains on Thursday morning. && .SHORT TERM... (This evening through Wednesday) Issued at 201 PM CST Tue Nov 26 2024 Breezy southwesterly winds will continue through this afternoon but will taper off this evening. Winds this evening will veer to the west as a surface trough moves to the east. Low temperatures tonight will be well above seasonal normals in the upper 40s to lower 50s as an approaching upper level shortwave brings breezy winds and high clouds overnight. The shortwave will move east over the Central Plains before deamplifying and absorbing into a broad upper trough bringing zonal flow aloft again. Day time heating will bring above seasonal normal high temperatures tomorrow in the 60s to 70s and breezy west winds tomorrow afternoon. An upper level low sitting over western Canada will push a strong cold front through our region late in the afternoon veering the winds to the north. && .LONG TERM... (Wednesday night through next Monday) Issued at 201 PM CST Tue Nov 26 2024 The cold front will continue to plow through the rest of the area on Wednesday evening. Strong pressure rises behind the front will persist through the overnight hours keeping winds elevated. Despite the stronger winds, temperatures will be much colder due to the cold air advection in the wake of the front. Surface ridging will settle over the area after sunrise leading to a decrease in winds. The other issue will be the potential for very light wintry precipitation Wednesday night through Thursday morning. The column will saturate from the top down with the lower level moisture arriving behind the cold front. Frontogenesis around the 750-650mb layer will bring weak lift within the lower level saturated layer. However, towards Thursday morning, mid levels of the atmosphere will begin to dry out leaving a cloud layer mostly warmer than -8C or so. Air near the surface is expected to wet bulb down close to 0C or even slightly below 0C for areas on the caprock, especially across the western South Plains and extreme southwestern Texas Panhandle. Although this activity is primarily expected to be sprinkles and flurries, some drizzle/freezing drizzle may mix in given the relatively warm cloud layer. Cold air advection will continue through the day on Thursday allowing temperatures to struggle to get out of the 40s area wide. Temperatures will warm on Friday and Saturday as surface lee troughing develops swinging winds around to a downsloping component to the southwest. Another weaker cold front is expected on Saturday which will stunt the brief warmup after Thanksgiving. && .AVIATION... (18Z TAFS) Issued at 1131 AM CST Tue Nov 26 2024 VFR conditions to prevail at all TAF sites. Winds will become breezy this afternoon around 15 to 20 knots with gusts up to 25 to 30 knots before diminishing this evening as they veer to the west. Winds aloft will increase tonight with LLWS occurring around 500 feet up to 40 knots at all sites through tomorrow morning. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...10 LONG TERM....01 AVIATION...10
