NWS El Paso, TX wrote its last area forecast discussion before the first event at Aug 11, 1:19 PM MST, 56 minutes earlier.
Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 219 PM MDT Thu Aug 11 2022 .SYNOPSIS... An active monsoon weather pattern will continue through next week. Scattered to numerous showers and thunderstorms with a potential for heavy rain and flash flooding will occur this afternoon through Friday night. There will be decrease in thunderstorm activity during the weekend with less coverage with a light to moderate rain pattern. Additional moisture next week will increase shower and thunderstorm activity with a potential for heavy rain and flooding. Temperatures will remain seasonal through the period. && .DISCUSSION... .SHORT TERM...Tonight and Friday... Very active weather is expected into Friday across the Borderland. There is plenty of moisture situated over the area this afternoon with dew points at 60-65 degrees and PW's between 1.2-1.5 inches. The EPZ 12z sounding showed PW's at 1.44 inches which may have been a bit high since there were clouds overhead at that time. Even taking that into account, a more accurate value would still be about 40% above normal and we are right around the climatological peak for monsoonal moisture. Widespread slow-moving thunderstorms are ongoing over our eastern areas as of 19z and have been producing areas of flash flooding. This activity should spread across the lowlands into this evening, but probably not as widespread or heavy. A Flood Watch remains in effect through tonight for the Sacramentos and the Gila Region. This does not mean that the other lowland areas are excluded from localized flooding and heavy rainfall. Small hail and strong winds over 40 mph are possible into the overnight as isolated to scattered thunderstorms linger. The main culprit of this moisture influx is a shortwave trough that is currently splitting NM in half from northwest to southeast. This disturbance will reach the Sacramentos first this evening and slowly progress through the CWA from east to west tomorrow. This will lower the threat for heavy rainfall and flash flooding over the Sacramentos as moisture levels decrease behind the shortwave. The Gila Region however, should still see a good amount of thunderstorm development during the afternoon, provided that any overnight clouds clear out in time for peak heating. Scattered storms are forecast again for the lowlands tomorrow as PW's stay in the same 1.2-1.5 inch range. Localized flash flooding and heavy rainfall are possible as a result. Small hail and strong winds may occur as well with these storms. Temperatures remain near or a few degrees below normal through tomorrow with highs in the low 90s in the lowlands. && .LONG TERM...Friday night through next Thursday. A stationary area of high pressure will remain centered over the northern Texas panhandle during the weekend through next Tuesday. This monsoonal pattern will keep the local area under a moist easterly to southeasterly flow that will continue to help develop shower and thunderstorm activity through all of next week. For this weekend, the weak upper low over the local region will move away from the area by Friday night. At the same time a somewhat drier continental air mass will be ingested into the easterly flow which lower lower precipitable water values to seasonal normals. This should result in a general decrease in shower and thunderstorm activity during the weekend with the greatest chance of thunderstorms mostly occurring from Deming westward to the Arizona State line. The remainder of the area will continue to have at least a slight chance of thunderstorms. With lower precipitable water values, storms will not be quite as efficient at producing rain with mostly periods of light to moderate rainfall expected with the occasional heavy rain producer from stronger storms. Mountains will continue have greater coverage of thunderstorm development. For Monday, thunderstorm development will continue to be isolated to widely scattered as a drier air mass continues to limit thunderstorm development. That will change on Tuesday as increased moisture and an easterly wave/inverted low pressure trough approaches the area from the gulf of Mexico. This weak system will increase chances for thunderstorm development with a potential for heavy rainfall, flooding and strong storms on Tuesday. Similarly, a weak trough will drop down from the north near the region to help initiate stronger convection through Wednesday and Thursday. Storm coverage Tuesday through Thursday will be scattered to numerous in the afternoon and evening with more isolated storm development in the morning hours. && .AVIATION...18ZFR conditions expected for much of the forecast. VCSH continues for KTCS until 21z as a band of light- moderate rain sits just to the S. BKN-OVC to start with TS developing in afternoon and VCTS introduced between 20-23z for TAF sites. Confidence is low on TS timing due to clouds overhead which may suppress development. Amendments seem likely before 0z cycle. VRB25G35KT and VIS < 3SM possible with storms into evening. TS dissipate overnight with BKN-OVC100-120. && .FIRE WEATHER... Fire weather concerns are not expected through the first half of next week. Abundant moisture keeps the threat going for scattered to widespread thunderstorms for Friday. Drier air moves in for the weekend, lowering the chance of storms but not entirely. Mountains and western areas will see the best chance of activity into next week. Temperatures stay near or slightly below normal with modest winds outside of outflows. Min RH's range from 20-35% in the lowlands and from 40-65% in the mountains through early next week. Ventilation rates range from poor to very good during the same timeframe. && .PRELIMINARY POINT TEMPS/POPS...
