733 FXUS64 KLUB 161124 AFDLUB Area Forecast Discussion National Weather Service Lubbock TX 624 AM CDT Sun Oct 16 2022 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 315 AM CDT Sun Oct 16 2022 The quasi-stationary boundary located along a line from Muleshoe to near Palo Duro Canyon to Clarendon as of 2 AM will start to once again push south early this morning thanks to outflow boundaries out of the Texas Panhandle and southwest Oklahoma. As this "cold" front pushes south, precipitation coverage should start to increase. This will result in a rather cool day with high temperatures in the 50s expected over much of the area, reaching into the 60s over our southern zones. With the lack of strong insolation this afternoon, CAPE values will only get up to 300-500 J/kg. These values are expected to decrease through the day, leading to very isolated thunderstorms with more widespread showers. As the upper low, located near the SE Cal / SW AZ border as of 3 AM, begins its trek towards the region, large-scale ascent will begin to increase. This increase in ascent will result in an additional boost in precipitation coverage over the forecast area. With PWAT values nearing the daily max, increasing ascent causing the potential for heavier rain, and the potential for multiple rounds of showers to move over the same area, localized flooding will be possible. This is especially true for areas of the southern South Plains that have received significant rain over the past few weeks, resulting in the soil becoming nearly saturated. GKendrick && .LONG TERM... (Monday through Saturday) Issued at 315 AM CDT Sun Oct 16 2022 Forecast thinking remains on track this morning with very few changes to the long term forecast. By Monday morning the aforementioned low will be centered over New Mexico with ongoing showers across mainly our southern and western zones. This low will begin to be absorbed by the broader troughing located over the eastern half of the CONUS during the day while ridging remains in place across the western half of the CONUS. Until the low moves east of the forecast area, which is expected by Tuesday morning, rain showers will continue across the forecast area. But with lessening upper-level dynamics and moisture, both coverage and intensity should wane through the day. This cloud cover and precipitation will keep temperatures well below average once again with high temperatures ranging from the middle 50s to the lower 60s on Monday. Upper-level ridging will remain in place over the western CONUS through about Thursday. This will place the forecast area under northwest flow aloft, allowing temperatures to moderate through the week with dry conditions prevailing. By Friday, troughing will begin to strengthen across the western CONUS with several shortwaves expected to move southeast towards the forecast area. This should allow for lee surface cyclone development late in the week and into the weekend bringing westerly to southwesterly winds back to the forecast area and hence a bump up in high temperatures back into the 70s and 80s. Dry air will remain over the forecast area through next weekend hence the long term forecast remains dry at this time. There continues to be uncertainty with a low off the California coast that is expected to move across the Desert Southwest towards our area but guidance has delayed this quite a bit compared to previous runs. Now this feature is not expected to possibly play a role in our weather until after the weekend. /WI && .AVIATION... (12Z TAFS) Issued at 619 AM CDT Sun Oct 16 2022 Rain coverage will increase throughout the day at all terminals. CIGS should remain near VFR/MVFR criteria; however, there will be periods of IFR. Especially if a heavy shower moves near or over a terminal. Showers will begin to decrease from east to west late tonight. && .LUB WATCHES/WARNINGS/ADVISORIES...
