415 FXUS64 KEPZ 051218 AFDEPZ Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 618 AM MDT Fri Jun 5 2026 ...New AVIATION, FIRE WEATHER... .KEY MESSAGES... Updated at 957 PM MDT Thu Jun 4 2026 - Thunderstorm chances continue Friday and Saturday, though Saturday limited mostly to areas east of the Rio Grande Valley. - Continued risks for flooding from storms possible again Friday, along with gusty winds and hail. - Drier and warmer on Sunday through Wednesday with many lowland areas seeing their first 100 degree days of the season. && .DISCUSSION... Issued at 957 PM MDT Thu Jun 4 2026 Upper low over the central Gulf of California continues to slowly drift northeast pulling up a fair amount of sub-tropical moisture with it. Models show the low between El Paso and the Big Bend Friday afternoon, so expect another round of thunderstorms. MCV, which was over the eastern CWA this afternoon, likely caused some subsidence to its lee over much of the central CWA. This feature should be well out of the area Friday, with the upper low now the main driver. Models showing modest CAPE values of 500-1000 J/kg and PWs of .75 to 1.00 inch well aid in thunderstorm development Friday, with areas from the Rio Grande Valley east with the highest chances. DCAPEs as high as 1000 J/kg and dewpoint depressions of 40-50 degrees point towards winds being the biggest threat, but flooding and hail will also likely be present. Saturday should see less storm activity as the upper low drifts over the Texas Panhandle. Thunderstorms mainly limited to areas east of the Rio Grande Valley as this is the last holdout for moisture and instability. Sunday through Tuesday...upper ridge builds in over the area behind the exiting upper low. Low level warmth increases and 850 mb temps support lowland triple digits, if not by Sunday, then Monday and Tuesday. Wednesday and Thursday...Next Pacific system begins moving onshore, displacing the upper ridge further east. Though both GFS/ECMWF show increasing southerly flow tapping into sub-tropical moisture and moving it to our area, the GFS digs the Pacific low much further south (to near the Four Corners Wednesday) and hence much deeper moisture/higher PWs. Thus, GFS Wednesday shows likely thunderstorms, while ECMWF Wednesday just rates a slight chance. The tables flip Thursday as the southerly GFS low passes by, bringing in drier west flow. The ECMWF on Thursday still shows sub- tropical moisture tap since the upper winds remain more southerly. Hence the ECMWF shows the chances of thunderstorms for Thursday. && .AVIATION... (12Z TAFS) Issued at 613 AM MDT Fri Jun 5 2026 Hazy conditions have been observed across much of the Rio Grande valley and Tularosa Basin overnight and early this morning. This appears to be dust fallout from thunderstorm outflow last night. Impacts are limited, but some automated obs have been reporting false ceilings. KDNA, for example, is carrying BKN003, though there is no noticeable reduction in vertical visibility. Otherwise, expect scattered thunderstorms again today, starting in the higher terrain, and drifting south and southwest, now that we are on the backside of a trough and a departing upper low that'll be moving from Chihuahua into the Big Bend. Gusty outflow winds from the NE look to arrive at ELP around 00Z, with a good chance of initiating additional thunderstorms in the area. Conditions will improve after 03Z as thunderstorms diminish into showers before dissipating. && .FIRE WEATHER... Issued at 613 AM MDT Fri Jun 5 2026 One final day of showers and thunderstorms in the area today, which will be followed by a warming and drying trend this weekend and into early next week. By Monday, more typical June weather will arrive, with high temperatures in the low 100s across the lowland deserts. RH values will drop into the 10s near the Arizona border today, and will spread east through the weekend. && .PRELIMINARY POINT TEMPS/POPS...
