016 FXUS64 KLUB 200706 AFDLUB Area Forecast Discussion National Weather Service Lubbock TX 206 AM CDT Thu Jun 20 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today and tonight) Issued at 203 AM CDT Thu Jun 20 2024 Mid level ridging extends from New Mexico to the Ohio Valley early this morning with the ridge axis lying over the forecast area with little movement expected to it. However, low to mid level moisture is high with progged soundings reflecting a nearly saturated profile up to around 400 mb before drying out above that while the temperature profile is moist adiabatic. Farther to our south T.S. Alberto will come ashore on the Mexican coast south of Brownsville and will move quickly inland with an extension of its trough and moisture working northward through southwest Texas. Models continue to show scattered showers and isolated thunder moving across mainly the southwestern third to half of the forecast area late morning through afternoon while lingering low to mid level moisture weakly capped aloft potentially leading to additional scattered showers and isolated thunder in a somewhat typical West Texas nocturnal and tropical setup. Progged soundings show PWATs upwards of 1.67 inches across the southwestern zones, but modest CAPE values of less than 500 J/kg suggest most of that precipitation potential will be limited. Temperatures will be relatively cool again today due to low to mid cloud cover and persistent moist southeasterly low level flow. && .LONG TERM... (Friday through Wednesday) Issued at 203 AM CDT Thu Jun 20 2024 Isolated showers and thunderstorms will end across the far southeastern Panhandle Friday morning. Some minimal PoPs have been retained in this same area for Sunday evening near a weak upper wave, however hot and dry conditions are expected to prevail across much of the area as a ridge strengthens to the west. High temperatures will gradually increase from the low 90s on Saturday to near 100 by early next week. NBM PoPs rise to chances of showers and storms next Wednesday and Thursday. Although they have been unchanged in the current forecast given the inherent uncertainty this far out, they may be a bit optimistic as upper heights would indicate a strongly capped environment. && .AVIATION... (06Z TAFS) Issued at 1216 AM CDT Thu Jun 20 2024 Low level moisture remains in place across the forecast area with increasing mid level moisture moving into the area as a tropical inverted trough moves eastward across northern Mexico. Showers, possibly a TS, and perhaps some MVFR ceilings will primarily affect areas to the south and southwest of the terminals today. May insert a SH and MVFR ceilings into the TAFs later once confidence in areal coverage and timing increases. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...07 LONG TERM....19 AVIATION...07
