234 FXUS64 KSJT 191127 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 627 AM CDT Sat Aug 19 2023 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 357 AM CDT Sat Aug 19 2023 The upper high will be centered over Kansas and Oklahoma through tonight and will shift a bit farther northeast by Sunday. Very hot and dry conditions will prevail again today, with record temperatures possible once again. The current records are 105 for Abilene and 106 for San Angelo, with current forecast highs of 107 for both locations. An Excessive Heat Warning will be in effect again today from 1 to 9 PM for most of the area. The exception will be over far southwest counties where a Heat Advisory will be in effect, as temperatures will be a little cooler over this area. Temperatures will be warm again tonight, with overnight lows in the 70s. && .LONG TERM... (Sunday through Friday) Issued at 421 AM CDT Sat Aug 19 2023 Both the GFS and the ECMWF are in agreement that the center of the high pressure will gradually shift off to the northeast over the next few days. Regardless of this, Excessive Heat Warnings or Heat Advisories are likely to be needed anyway. One area of disagreement remains in the mid week tropical system rolling off the Gulf of Mexico. The ECMWF brings in a more pronounced system with decent rainfall totals across our area. However, the GFS brings in a weaker system with a track that largely keeps most of the rain across the southern portions of our area, but the two models are closer to agreement than yesterday. Confidence is very low in either solution being right or wrong. As such, rain chances are still limited to 40 percent along I-10 and southward for now. This is largely due to the amount of uncertainty in the forecast. && .AVIATION... (12Z TAFS) Issued at 611 AM CDT Sat Aug 19 2023 VFR conditions will prevail the next 24 hours.
