016 FXUS64 KLUB 222325 AFDLUB Area Forecast Discussion National Weather Service Lubbock TX 525 PM CST Fri Nov 22 2024 ...New AVIATION... .KEY MESSAGES... Updated at 522 PM CST Fri Nov 22 2024 - Warm, dry and slightly breezy conditions this weekend. - A cold front Monday will kick start the cooler trend for next week. && .SHORT TERM... (This evening through Saturday) Issued at 206 PM CST Fri Nov 22 2024 Quiet conditions are expected to continue tonight through tomorrow. The axis of the upper ridge just to our west will push eastward towards the FA tonight before being nearly overhead by late tomorrow morning. A weakness in the upper ridge is still expected to pass overhead during this time, but it will have little effect on surface conditions. Persistent surface lee troughing will keep winds out of the southwest tonight and tomorrow. Though winds will be light, they will help to keep overnight lows near to a degree or two warmer than this morning`s lows. && .LONG TERM... (Saturday night through next Thursday) Issued at 206 PM CST Fri Nov 22 2024 Warm through the weekend and cooling into next week looks to be the main story of the long term period. Northwest flow aloft is expected to become more zonal by the beginning of the period as a shortwave trough tracks through SK which will work to flatten and push the upper level ridge to the east. A surface trough in the lee of the Rockies will prevail and dig southward through the Southern Plains on Sunday. This will lead to breezy southwesterly winds around 10 to 20 mph, which in combination with sunny skies and increased thickness and height values will lead to high temperatures above seasonal normals in the mid to upper 70s, and even near 80 degrees across the far southwestern Texas Panhandle. Thankfully the above normal temperatures will not last long as the surface low ejects to the east Sunday night, making way for a cold front to push through our area Monday. Model guidance currently projects the front making its way into our northern counties by mid-morning Monday pushing its way completely through by the late afternoon hours. Behind the front, northerly winds will remain rather light around 10 to 15 mph with the strongest winds fixated across areas east of I-27. Overnight temperatures will be nearly 10 to 15 degrees cooler compared to previous nights as the surface high pushes southward and ushers in the much cooler canadian airmass from the north. This will lead to temperatures in the upper 20s to mid 30s, with temperatures likely below freezing for areas across the Caprock. Tuesday will be slightly warmer but near seasonal normals, as southwest surface winds quickly return as a surface trough develops in southeastern CO. As we head into the overnight hours Tuesday, a lee cyclone is expected to develop as the upper level trough that has been stationary over the PacNW the past few days finally ejects eastward into the Intermountain West. Both ensemble and deterministic guidance keeps this as an open wave/ positively tilted trough as it scoots into the Central and Southern Plains Thanksgiving Day. This will then swing an additional cold front across the FA early Thursday morning, with temperatures forecasted about 15 degrees cooler than previous days. At this time, this front looks to remain dry given the lack there of moisture present. However, there is quite a bit of uncertainty between the GFS (more moist) and the ECMWF (drier) so depending on which model becomes more consistent over the next few days will give better knowledge in regards to precipitation on Thanksgiving. && .AVIATION... (00Z TAFS) Issued at 522 PM CST Fri Nov 22 2024 VFR conditions will prevail at all TAF sites. Winds will be light and from the south before becoming slightly breezy and veering to the southwest tomorrow. && .LUB WATCHES/WARNINGS/ADVISORIES...
