038 FXUS64 KCRP 250820 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 220 AM CST Mon Nov 25 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Tuesday) Issued at 219 AM CST Mon Nov 25 2024 Key Messages: - Well above normal temperatures Monday, more seasonal Tuesday Zonal flow aloft and onshore flow at the surface will continue to promote warm and dry conditions, leading to daytime high temperatures well above normal. A weak cold front Monday night will usher in a bit cooler airmass along with drier air that will allow temperatures to decrease to more seasonal levels Tuesday. High temperatures Monday are expected to range from the mid to upper 80s while highs Tuesday are expected to range from the lower to upper 70s. Despite PWAT values of 1.1-1.3" which ranks in the 60-75th percentile for this time of the year, the lack of lifting due to the absence of vorticity with this weak front will inhibit the development of showers and storms. && .LONG TERM... (Tuesday night through next Sunday) Issued at 219 AM CST Mon Nov 25 2024 Key Messages: - Stronger cold front for Thanksgiving Day - Secondary cold front this weekend Thankfully, a change of pace is expected in the long term with these abnormally warm temperatures finally coming back to seasonal levels, and perhaps even slightly below normal levels. A series of cold fronts are expected in the long term with higher confidence with the first front Thanksgiving Day. Models are becoming better aligned with the strength of the first cold front, however, continuing to have disagreements in regards to timing. The ECMWF is showing a quicker frontal passage on Thanksgiving morning while the GFS is showing later frontal passage in the afternoon to evening hours. When this front sweeps across the region will play a significant role in our high temperature on Thanksgiving Day. At this time, went with a blend of models to show seasonal temperatures Thursday with the colder air advecting southward Friday. Onshore flow is expected to return early this weekend with a secondary front sweeping across the region late this weekend cooling us down once again. One last warm day is expected Wednesday with temperatures ranging from the mid to upper 80s before dropping to the mid to upper 70s Thursday with the frontal passage. High temperatures Friday in the wake of the front will be slightly below normal with highs in the upper 60s, struggling to reach 70 degrees. A slight warmup Saturday is expected with the return of onshore flow before the second cold front sweeps across the region bringing us down back to the 60s. Overnight temperatures Wednesday night are expected to range from the mid 50s to mid 60s before dropping into the 40s and 50s Thursday night through th weekend. Rain chances will be slim (less than 10%) through this weekend despite the passage of a couple of cold fronts due to unfavorable dynamics. While confidence is low at this time, our next best chance for rain appears to be late this weekend into early next week with low to medium (20-40%) chances for showers. && .AVIATION... (06Z TAFS) Issued at 1118 PM CST Sun Nov 24 2024 Light southeasterly winds will continue through the early morning hours before strengthening to sustained 12-15 knots and gusts around 20 knots in the afternoon. Chances of fog has increased since the last forecast package, now a 30-50% chance mainly over the inland Coastal Plains and Brush Country. The more prone areas of VCT/ALI may see vsbys even less than in the forecast but confidence is low to include at this time. Have included a window for LRD and COT as well for patchy fog. A cold front will extend into VCT and COT near the end of the forecast, shifting winds out of the north to northeast. && .MARINE... Issued at 219 AM CST Mon Nov 25 2024 Moderate to strong southerly flow will continue this morning and gradually relax to more moderate levels late this morning into this afternoon. Winds will shift to the north late Monday night and strengthen back to moderate to strong levels in the wake of a weak cold front. Winds will quickly relax to weaker levels and shift back to the southeast Tuesday evening. These weaker winds will be short lived as winds are expected to restrengthen to moderate to strong levels Wednesday ahead of a cold front Thanksgiving Day that will shift winds back to the north. && .PRELIMINARY POINT TEMPS/POPS...
