.SHORT TERM... (Today through Tuesday afternoon) Issued at 218 AM CDT Mon Sep 29 2025
Water vapor imagery and 500 mb height analysis shows an upper level trough lifting toward the Four Corners early this morning. Abundant mid and upper level moisture continues to stream across much of west Texas and southeast New Mexico within the southwesterly flow pattern aloft in advance of this feature. Scattered to numerous rain showers and a few embedded thunderstorms made it as far east as the Trans Pecos region Sunday evening before quickly diminishing during the late evening hours. The Flood Watch that was in effect from Eddy county down into the Davis Mountains/Marfa Plateau region was discontinued as of 10 PM CDT / 9 PM MDT as heavy rains had ended. A few light rain showers will remain possible over areas mainly west of the Pecos River through sunrise given weak ascent within the southwesterly flow pattern aloft and the abundant moisture in place.
The upper-level trough will slowly lift toward the Rocky Mountains and adjacent plains of New Mexico and west Texas today, before gradually moving to our east tonight into Tuesday morning. Abundant mid and high level cloud cover will continue to spread across our forecast area ahead of this feature and will keep skies cloudy across much of our region through the afternoon. The combination of the available moisture and continued weak ascent within the southwesterly flow pattern aloft along and ahead of the approaching trough may allow for the development of isolated to scattered showers and maybe a thunderstorm or two again today. We will keep 20-40% POPs generally oriented across areas west of the Pecos River today. There has been a trend in CAMs with showing at least isolated showers potentially developing as far east as the Permian Basin this afternoon, but the chance of measurable rain looks to be less than 20%. The thick cloud cover will limit heating today, so highs are only expected to reach into the mid 70s to lower 80s across most of the forecast area, except slightly warmer in the upper 80s to lower 90s along the Rio Grande. Rain chances will quickly diminish by early this evening as the upper-level trough starts getting a push to our east. Clouds should decrease through the evening and overnight hours. Low temperatures should range in the mid 50s to mid 60s across most of the area.
The upper-level trough continues to move to the east across Oklahoma and eastern portions of Texas on Tuesday while ridging aloft starts to build into west Texas and southeast New Mexico behind this departing feature. Mostly sunny skies and dry conditions will return to our area on Tuesday with highs reaching into the 80s for most places (except lower to mid 90s along the Rio Grande).

.LONG TERM... (Tuesday night through Sunday) Issued at 218 AM CDT Mon Sep 29 2025
Upper-level ridging will continue to amplify across west Texas and southeast New Mexico through the middle to latter part of the week. Mostly clear skies and dry conditions will prevail with POPs staying nil through Friday. The ridging pattern may shift to our east and become replaced with southwesterly flow aloft next weekend ahead of a series of upper-level troughs that are forecast to deepen over the western U.S. There will be little in the way of meaningful moisture that will be in place over our area, so dry conditions are forecast to continue through the upcoming weekend. High temperatures will be warming back up into the upper 80s to lower 90s over most of the area Wednesday-Friday underneath the ridging pattern aloft. Highs may tick down a degree or two by next weekend, but still quite warm in the mid 80s to lower 90s for most. Overnight lows will generally range in the lower to mid 60s over most of the area, except for readings in the 50s over higher elevation areas.

.AVIATION... (12Z TAFS) Issued at 634 AM CDT Mon Sep 29 2025
VFR conditions will remain prevalent across the region underneath broken-overcast mid and high level cloud decks streaming overhead. A few very light showers will develop across the area through the early morning hours with another round of isolated to scattered showers and thunderstorms developing through this afternoon. Confidence of impact remains too low to include convective mention at any terminal. Winds will generally become southeasterly to easterly at 5-10 knots today.
