Area Forecast Discussion National Weather Service San Angelo TX 722 PM CDT Thu Jun 15 2017 .UPDATE... Increased shower and thunderstorm chances to likely for complex of storms moving southeast into the Country. HRRR has the storms complex continuing move southeast into the Big Country and northern Concho Valley...and as far east as Brown and San Saba Counties. Some could be severe...with large hail and damaging winds the main threats. 04 && .PREV DISCUSSION... /issued 629 PM CDT Thu Jun 15 2017/ AVIATION... /00Z TAFS/ VFR conditions continue across West Central Texas early this evening, but complex of storms across the South Plains should move southeast and approach the area later this evening. Latest hi-res models suggest that KABI (Abilene) will be the most likely one to see any of these storms and will continue the VCTS for now. May need to update once storm trajectory becomes more certain. Otherwise, will leave storms out for now. MVFR cigs will return by morning and will largely us the timing from this morning as a start and stop point on the low clouds. PREV DISCUSSION... /issued 332 PM CDT Thu Jun 15 2017/ SHORT TERM... (Tonight and Friday) As of mid afternoon, widely scattered thunderstorms have developed across the dryline in Lubbok's CWA as indicated by many of the short range models this morning. These storms are expected to continue to develop towards the southeast and be located near the Big Country by early evening. Additional storms may develop near Midland later this afternoon in a manner similar to yesterday and could reach the western border of our CWA later this evening. MLCAPE values near 3700-4200 j/kg coupled with 30-40 kts of 0-6 km shear will allow for the possibility of some of these storms to become severe. If the stronger cells hold together and move into our CWA, the primary hazards will be large hail and damaging winds. The storms will likely dissipate by midnight, leaving the best rain chances along the western border of the CWA and the Big Country. For tomorrow, rain chances will have diminished overnight. The heat will once again return to West Central Texas bringing high temperatures into the upper 90s to 104. Low temperatures tonight are expected to drop into the low to mid 70s. LONG TERM... (Friday night through Thursday) An upper level ridge will centered across northern Mexico or the Southwest U.S. through the extended forecast, with its influence extending into the western half of Texas. Well above normal temperatures are forecast both Saturday and Sunday. High temperatures on Saturday will mainly be in the 100 to 105 range. A heat advisory may eventually be needed, as several locations may reach or exceed 103 degrees. An upper level trough will swing across the Plains Sunday, sending a cold front into the Big Country Sunday afternoon. High temperatures on Sunday will be dependent on the eventual strength and speed of this cold front. Ahead of the front, compressional heating will result in triple digit temperatures, while temperatures in the 80s will be possible behind the front. For now, only minor changes were made to temperatures, but these temperatures may need to be trended down, especially across the northern half of the forecast area. Slightly cooler temperature are forecast on Monday behind the front, with highs mainly in low to mid 90s. Upper level ridging will build back into West Central Texas for the middle to latter part of the work week. This will result in mainly dry conditions and temperatures above seasonal normals. && .PRELIMINARY POINT TEMPS/POPS...
