A deep east-southeast monsoon flow brought plenty of Gulf of Mexico moisture into the region. A weak surface low extended through southwest New Mexico which helped to fuel slow moving thunderstorms with heavy rain and flash flooding.

Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 554 PM MDT Mon Aug 8 2022 ...UPDATED FOR 00Z TAF ISSUANCE... .AVIATION...00Z TAF CYCLE... Scattered shower and thunderstorm coverage through at least 03Z with some ISOL TSRA lingering beyond 06Z. Aviation impacts will be due to low cig, gusty outflow winds to 35-45kts, and reduced VSBY in RA+ and possibly local BD. Temporary MVFR and possibly IFR conditions due to the storm activity. Prevailing weather will be skies FEW-SCT090 SCT-BKN150, with SFC winds 030-090 at 08-12KT. && .SYNOPSIS... Monsoonal pattern with daily afternoon and evening scattered showers and thunderstorms will remain through the week. Expect locally heavy rain, gusty winds, frequent lightning, and small hail with the strongest storms. Widespread flooding is not expected at this time but isolated instances will be possible each afternoon. This week will feature seasonable temperatures, 90s across the lowlands and 60s and 70s in the higher terrain of area mountains. && .DISCUSSION... .SHORT TERM... As expected, moisture parameters are much more favorable for greater thunderstorm coverage this afternoon compared to yesterday. Precipitable water has increased to around 1.2", which has also pushed CAPE to around 1000 J/kg. The lack of any notable wind shear continues to hinder storm organization, so activity will be spotty and short-lived as is typical for the monsoon season. Expect an active evening of convective activity, with plentiful mountain (40- 60% coverage) and scattered lowland (25-40% coverage) thunderstorms. The best chances for rain (at least early on) will definitely favor to west slopes of the Sacramento Mountains and US-54 corridor in Otero County with outflow spreading area wide into this evening. High pressure aloft remains fixed to our north over the southern Rockies today with a steady east flow through much of the atmospheric column. Slow westward storm motion is expected this evening, with the potential for strong thunderstorm outflows and wind gusts up to 50 mph. Lowland highs will reach the mid-to-upper 90's today, a bit cooler than the past few days. This will be right near normal for early August. Very similar temperatures expected again tomorrow. Models tend to favor southwest New Mexico for storm chances tomorrow, where higher moisture will be present closer to the primary monsoonal plume into Arizona. Thus, focused PoPs west of the Rio Grande tomorrow. Similar hazards will be present with strong outflow winds and localized flooding. && .LONG TERM... Upper ridge will remain to the north, and eventually northeast of the Borderland through this upcoming weekend. Northeast/east flow will not only remain aloft, but also through much of the atmospheric column. This will keep the daily thunderstorm chances through the period, with the focus across area mountains. Temperatures will be rather stagnant as well, with values low to mid 90s across the lowlands and mid 60s to low 70s across the higher terrain of the Sacramento mtns and Black Range. Delving into the details a little more, Wednesday through Friday looks relatively similar, with weak to modest instability, dewpoints near 50 or in the 50s, and near normal PW. As a result, typical monsoonal conditions are expected with scattered storms over area mountains and isolated across most lowland locations. The exception will be those lucky lowland areas that see favorable outflow boundary interactions, then more scattered coverage is possible. Locally heavy rain will be a threat, along with gusty winds and small hail (mostly weak instability and low shear suggests small hail and gusty sub severe winds, but if locally higher instability/shear were to develop, more marginal hail/winds will be possible). By the weekend, the best chance for storm coverage looks to be west of the Rio Grande. That is where the best moisture and instability will exist, at least so it seems at this time, and hence the best chances. Cannot rule out isolated (~10-15%) lowland activity most locations however as near normal moisture and the potential for outflow induced thunderstorms will remain. Temps remain in the 90s across the lowlands with the typical monsoonal threats (mrgn winds, mrgn hail, and flooding) with the strongest thunderstorms. Early next week will feature more of the same, with scattered mtn storms and potentially isolated lowland activity. && .FIRE WEATHER... Low fire danger this week as opportunities for wetting rains continue. Typical monsoon pattern will remain in place with scattered showers and thunderstorms each afternoon and near normal temperatures. A few storms may produce locally heavy rainfall and rapid downstream rises in drainages and arroyos. Frequent lightning and gusty outflow winds are also possible. Relative humidity will dip to 30-40% midday, followed by excellent overnight recoveries. Smoke ventilation will be Good each afternoon with transport mainly to the W/NW. && .PRELIMINARY POINT TEMPS/POPS...

Rain amounts in excess of 1 inch per hour will be possible, which will cause flooding in most rural and urban environments. Heavy rains may cause flows to rise in downstream drainages and arroyos, even if no rainfall occurred at a certain location. Flooding may impact travel, especially near low water crossings and flood- prone areas. These storms will also be capable of producing gusty outflow winds and small hail. Wind gusts may cause damage to outdoor objects, especially near thunderstorm downbursts. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday Daily thunderstorm chances will continue with scattered mountain and isolated lowland coverage. Storms will be capable of producing strong winds, large hail, and locally heavy rainfall. .SPOTTER INFORMATION STATEMENT... Spotters are encouraged to report any severe weather or significant flooding to the National Weather Service. Dennhardt
