Area Forecast Discussion National Weather Service El Paso Tx/Santa Teresa NM 329 PM MDT Sat Sep 23 2017 .SYNOPSIS... Persistent upper trough continuing in place over the Great Basin for the next several days. Resultant southerly flow aloft will bring some tropical moisture across the area. A chance of thunderstorms will continue through Monday, mainly from El Paso east. A cool front moves in from the east Tuesday, spreading the moisture to areas west of the Rio Grande Valley. From Tuesday through most of the remainder of the week, the entire area will see scattered thunderstorms. A few could become severe, with large hail and damaging winds. Temperatures after Tuesday will cool below normal. && .DISCUSSION... Persistent long wave upper trough over the Great Basin will continue in place with very little movement through mid to late portion of next week. Sub tropical moisture continues to stream northward in the southerly flow aloft. WV imagery shows plume still from about El Paso east, although deepest layered moisture now east of the CWA. Will keep Flash Flood Watch in for eastern CWA, but have less confidence in this now. Short wave rotating out of the trough and to the Gila Region now. Lots of CU with this feature, along with a few showers, but left POPs out of this area tonight as short wave should be through. Sunday and Monday...moisture plume continues to hang on in the far eastern CWA, so kept low POPs in for eastern Hudspeth and Otero Counties. Tuesday through Saturday...back door front begins moving in Monday afternoon, although better push isn't until Tuesday afternoon. This easterly push will distribute moisture more evenly across the CWA, hence higher POPs begin all areas for most of this period. Modest MUCAPES and good shear environment point to the possibility of some severe thunderstorms. ECMWF quite similar to GFS with overall synoptic pattern, but not as bullish with the QPF. Looks like Wed/Thur will be the best window for thunderstorms. New closed low forms over Arizona Wednesday night, adding some upper dynamics to the mix. && .AVIATION...Valid 24/00Z-25/00Z... A moisture plume from Mexico is bringing some moisture to the area through the forecast period. Risk of isolated to scattered showers and thunderstorms all areas 00Z-06Z the east of the Rio Grande 06Z- 12Z then SE Hudspeth County after 12Z SCT060 SCT100 SCT160 except briefly in shower and thunderstorm areas SCT-BKN040 BKN-OVC100 2SM TSRA WIND GUSTS 30-40KTS. Brief MVFR IFR in heavier showers. After 12Z all areas except SE Hudspeth County; ClR TO SCT060 SCT120. Winds gnly until 06Z then SW08KTS. && .FIRE WEATHER... A deepening upper level trough over the western U.S. is pulling some enhanced mid-level moisture into areas near and east of the Rio Grande today. This will result in an increase in showers and thunderstorms through Saturday. Drier air will persist over SW New Mexico. Temperatures will slowly drop to near normal by Sunday. A backdoor cold front will bring cooler temperatures and more widespread precipitation by Tuesday, mainly for areas east of the Continental Divide. && .PRELIMINARY POINT TEMPS/POPS...
