623 FXUS64 KLUB 271703 AFDLUB Area Forecast Discussion National Weather Service Lubbock TX 1203 PM CDT Wed Mar 27 2024 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 214 AM CDT Wed Mar 27 2024 Water vapor imagery showed the base of a broad upper trough was shifting slowly across West Texas early this morning with one embedded impulse noted over the central TX Panhandle. A few showers accompanied this impulse, although this activity is expected to wane through daybreak. Surface obs at 2 AM revealed a weak low near Clovis with a stationary front draped southeast to near Big Spring. The low is forecast to redevelop southeast into the southern Rolling Plains later this afternoon all the while the stationary front creeps to near the Highway 84 corridor while dividing milder and occasionally breezy NW winds from cooler E-NE flow. Despite weak subsidence aloft on the heels of this morning's impulse, broad cyclonic NW flow aloft will maintain anomalously cold mid-level temps and favorable lapse rates. With sufficient heating, soundings look supportive for a few showers or even a brief thunderstorm later this afternoon, mainly N-NE of Lubbock, until this activity dwindles around sunset. Very spotty coverage warrants keeping PoPs below 20% for now. Strong height rises take hold overnight ahead of ridging for tomorrow. The stationary front meanwhile will become a cold front tonight while settling into the Permian Basin and eastern NM before ultimately washing out tomorrow morning. Mostly clear skies and light winds should garner one more night of below normal lows region wide. && .LONG TERM... (Thursday through Tuesday) Issued at 214 AM CDT Wed Mar 27 2024 An upper ridge will move into the area on Thursday brining warmer temperatures through the rest of the week. Highs on Friday will climb into the mid 80s across much of the area, slightly warming even further on Saturday and Sunday. Combined with breezy southwest winds of 15-25 mph and minimum RH values near 10%, fire weather concerns will be elevated. A deep upper trough will approach from the west on Monday, bringing about a significant pattern change. An associated strong surface cold front will move through as well and highs are expected to fall back into the 50s by Tuesday. Precipitation chances remain highly uncertain at this time, however it cannot be ruled out for any part of the forecast area. && .AVIATION...
