Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 1153 AM MDT Wed Jul 27 2022 ...UPDATED FOR 18Z TAF CYCLE... .AVIATION...18Z TAF CYCLE VFR conditions will generally continue through the TAF period. Southwest winds AOB 10KTs this afternoon with the exception of near thunderstorms becoming west southwesterly at 5-7KT tonight. Thunderstorms currently forming off the higher terrain this afternoon which will give each terminal a chance for VCTS from the 19-23Z time frame. Convection should begin to diminish after sunset, generally by 06Z. Hi-res models suggesting some showers moving northward out of Mexico after 06Z, which may affect KDMN, KELP, and KLRU. Did not have enough confidence to mention in the TAF. && .PREV DISCUSSION...304 AM MDT Wed Jul 27 2022... .SYNOPSIS... Monsoon moisture will remain plentiful for several more days. This means that daily chances for showers and storms will continue as temperatures stay seasonably warm. The heaviest rainfall will likely occur over area mountains and far western parts of the Borderland, However localized flooding could occur just about anywhere that storms manage to develop. && .DISCUSSION... .SHORT TERM...Today and Tonight... Most of the Borderland is quiet as of 8z except for a few leftover storms in the NM Bootheel and around Columbus. This activity is expected to dissipate by around sunrise with tranquil conditions elsewhere. An upper-level low/inverted trough is currently spinning over northern Chihuahua. It has been moving at a snail's pace over the past 48 hours to the northwest around a ridge that extends from central TX to off the Southeast US coast. This weak disturbance is expected to become less pronounced throughout the day but could find a new home in southeast AZ. The increased troughiness to the west of the CWA should keep the influx of moisture going along the NM-AZ border. PW's will stay above normal for late July around 1.25 inches with slightly higher values west of the Continental Divide. The higher terrain will fire up convection first by 18z and likely produce a few gusty outflows and spotty storms into the lowlands during the afternoon. Isolated to scattered thunderstorms then look to linger into this evening before winding down overnight as the atmosphere stabilizes. Our southern and western areas are most likely to see activity persist for Wednesday night. Heavy downpours and small hail are possible with some storms. Temperatures will again be around or just below normal today, reaching the low 90s in the lowlands. && .LONG TERM...Friday through Wednesday... A persistent upper ridge that stretches from the west coast to the southeastern states will still be in place as we start the long term period Thursday. This ridge is anchored by upper highs on both ends with one centered over northern California and the other along the coast of Georgia. However it is the circulation around the southeastern high that will have the dominant effect on the area early in the long range period as plentiful moisture continues to stream in from the south and southeast. While the core of the moisture plume will continue to get steered into Arizona to our west, the Borderland will certainly have sufficient moisture to keep our daily dose of showers and storms going for several more days. PWAT anomalies will be around .25" above normal Thursday and won't vary much as we head into the weekend. One thing to note will be what is left of an inverted trough that has been lurking nearby. This feature will become more diffuse with time as it takes up residence over Arizona, but I suspect it will help focus a greater coverage of showers and storms over our western zones at least Thursday and Friday. But with all the moisture around, daytime heating and lift provided by area mountains will result in at least some rain chances for just about all areas on a daily basis through the upcoming weekend. By early next week the upper high to our northwest should become the more dominant feature for us as it works it's way over Colorado and northern New Mexico. This would seem to indicate that with a more easterly flow into the area we would see some drying, especially for our eastern zones. And while models do show some drier air trying to push in, PWAT values should still run a tick or two above normal, so rain chances look to stay in the forecast for the entirety of this forecast package. && .FIRE WEATHER... Critical fire weather concerns are not expected into early next week. Monsoonal moisture will continue to stream in from the south each day, especially west of the Continental Divide. Daily showers and thunderstorms are most likely over the western areas, but the lowlands could see isolated activity. Frequent lightning and gusty winds are possible near storms or in passing outflows. Temperatures will remain near normal into next week. Outside of gusty outflows, surface winds will be light to modestly breezy. Min RH's will range from 20-35% in the lowlands and 40-65% in the mountains through the weekend. Ventilation rates will range from poor to very good during the same period. && .PRELIMINARY POINT TEMPS/POPS...
