Area Forecast Discussion National Weather Service Austin/San Antonio TX 1038 PM CST Sat Dec 31 2022 ...New AVIATION... .SHORT TERM... (Tonight through Sunday night) Issued at 1251 PM CST Sat Dec 31 2022 Southerly flow continues this afternoon with highs today around 15 degrees above normal for (very) late December. The normal maximum temperatures for today are 64 at DRT, 63 at SAT, and 62 at Austin sites, while actual highs in these locations will be in the upper 70s. Some breezy south to southwesterly winds are noted across the I- 35 corridor and Hill Country this afternoon with gusts up to 25 to 30 mph possible through sunset. Southerly winds become lighter overnight but bring increasing dewpoints across the area during this time. Lows will be varied, ranging from the mid 40s in the Rio Grande Plains and Edwards Plateau to the upper 50s in the Coastal Plains. Some stratus or fog will develop over the Coastal Plains Sunday morning, possibly even over the I-35 corridor briefly, although that would be the westernmost extend of it. By Sunday afternoon, highs will be in the mid to upper 70s areawide, with a few hotspots likely to reach into the low 80s. Not expecting any temperature records to be broken for the New Year, as records are solidly in the mid to upper 80s for January 1st. Afternoon dewpoints in the east will be in the 60s which will feel quite humid. An upper level trough over the Four Corners region begins to work its way east Sunday night into Monday with a surface low developing over Colorado. With ample moisture in place and an increasing low level jet, expect to see cloud cover develop to the east, gradually overspreading the area. Some showers are possible before sunrise over the eastern half of the area before additional chances for showers and thunderstorms are seen during the day. && .LONG TERM... (Monday through Saturday) Issued at 1251 PM CST Sat Dec 31 2022 As the upper low ejects NE into the Central Plains Monday, the dry slot sets up over South Central TX which is typical for La Nina cool season storm systems. Strong storms could materialize east of a Taylor to Cuero line but the gradient for rain chances drop off sharply as one gets to the Hwy 281 Corridor. A Pacific front trails the upper low with west to southwest winds for much of the day Monday. Near record high temps are expected as Monday should be the warmest day of the next week. West winds will also lead to warm temps Tuesday, but there will be some cool air advection to offset the downsloping winds. A cooling trend on min temps will pick up the pace by Wednesday night as a polar cold front arrives. A shortwave ridge moves over TX Friday to signal the next warming trend. && .AVIATION... (06Z TAFS) Issued at 1038 PM CST Sat Dec 31 2022 Fog and low stratus is developing along the TX coast and is expected to spread inland through the overnight and morning hours. There is some uncertainty as to whether or not the low cigs/vsbys will reach the I-35 corridor, though confidence is increasing that conditions could deteriorate by 14Z. Consequently, we have decided to go with a TEMPO LIFR group in the TAFs. There is greater confidence that low cigs (IFR conditions) will develop across the I-35 corridor by 02/0300Z. VFR conditions will prevail otherwise, especially at KDRT. Winds will be light tonight, picking back up out of the southeast during the day tomorrow. && .CLIMATE...
