Area Forecast Discussion National Weather Service El Paso Tx/Santa Teresa NM 222 PM MDT Mon Aug 7 2017 .SYNOPSIS... High pressure aloft will bring seasonably warm mostly dry weather to southern New Mexico and west Texas Tuesday and Wednesday with only a few mainly mountain area thunderstorms expected. Moist unstable air will flow back into the area beginning late Thursday and this will cause showers and thunderstorms with possible heavy rains to increase across the Borderland by the weekend and early next week. && .DISCUSSION... Upper ridge was aligned on an east to west axis just south of the border this afternoon with warm dry air aloft covering the region. However weak dry line also extending through central New Mexico with easterly winds mainly east of the Rio Grande pushing moist unstable air into the area. Surface dewpoints exceed 50 F east of the dry line and this moisture is combining with surface heating to produce moderately unstable air mass with early afternoon CAPEs above 1000 J/kg. Thus strong thunderstorms have developed over Otero County with radar indicating heavy rains and hail. Expect threat of stronger storms will continue over eastern portions of the CWA into tonight. To the west of the dry line dewpoints fall below 50 F via more westerly flow with little instability. Thus will forecast dry weather central/western sections. Tuesday through Wednesday summer monsoonal surface pattern will exist with low pressure or thermal trough west of the divide combining with high pressure to the east to induce east to southeast low level winds most locations. Thus low level moisture streams into the CWA with surface dewpoints mostly above 50 F and precipitable water above an inch. However upper ridge will be located across southern portions of the CWA with warm air and subsidence aloft keeping instability marginal. Thus convection will be mostly isolated around mountain areas Tuesday through Thursday afternoon. By late Thursday afternoon the upper ridge will have more of a northwest to southeast alignment and become located just north of the CWA. At low levels little change expected with thermal/heat trough west of the divide and high pressure east of the Rockies. This pattern will produce a deeper low to mid tropospheric east to southeast flow with advection of Gulf of Mexico water vapor gradually pushing precipitable water amounts to around 1.3 to 1.6 inches by Saturday afternoon. Consequently air mass will become more unstable with overall trends indicating increasing shower/thunderstorm coverage after Thursday afternoon especially Sunday or Monday when weak cold front enters the region from the east. Given the abundant moisture flash flood potential should rise significantly later periods as CAPE's expected to be around 1000 J/kg. && .AVIATION...Valid 08/00Z-09/00Z... Another day with generally VFR conditions. Winds will be mostly from the SE between 5 to 10 mph. Expect strongest winds speeds and gusts between 3Z and 9Z as a frontal boundary crosses through the region. Isolated showers and thunderstorms are possible in area mountains and the northern half of the forecast area. This could bring brief periods of MVFR conditions for KTCS. .FIRE WEATHER... Today is the driest day of the week across most parts due to the westerly flow as observed from water vapor satellite imagery. A southeasterly flow is going to increase moisture amounts starting tonight. Therefore, expect chances for showers and thunderstorms, especially for area mountains through the week with RH´s in the 30s for the lowlands and up to the 40s in the mountains. By next Sunday the monsoon moisture plume is going to be reestablished which will enhanced the coverage of wetting precip and even periods of heavy rain. Vent rates look poor and fair in the next two days, but they will improve by Thursday into the good and very good categories. && .PRELIMINARY POINT TEMPS/POPS...
