Short Term
(Tonight through Thursday night) Issued at 1215 PM CDT Wed Oct 21 2026
A mid level ridge axis that has been responsible for our continued dry and warm weather will not move much in the coming days. This ridge will eventually set up a strong Omega block pattern across the CONUS. This will continue to keep our area under mostly sunny to partly sunny skies with highs in the low to mid 80s and lows in the low to mid 50s each day in the short term. Chances of precipitation look slim to non nonexistent with the one exception being over the Rio Grande Plains. A decent amount of moisture may advance far enough northward into our area that may produce also a sprinkle or shower over the Rio Grande. Otherwise expect dry weather to persist areawide.
Long Term
(Friday through next Wednesday) Issued at 1215 PM CDT Wed Oct 21 2026
The omega block pattern remains through the end of the week before eventually showing signs of breaking down as a decent trough tries to dislodge it over the southwestern CONUS. As this happens we should have a few more days of warm and dry weather (highs in the 80s lows in the 50s) before we get into low chances for precip as moisture and humidity return on the back of southeasterly flow. This should allow temperatures to cool slightly as this trough begins to eject northeastward into the panhandles and thus possibly bringing with it a front southward into our area. Long range models are still having quite a difficult time handling this feature and the ensuing pattern change. For now have kept pops low, in the 15-30% range, starting Sunday and continuing into early next week. Continue to stay tuned as details become more refined as we get closer to the weekend.
Aviation
(00Z TAFS) Issued at 616 PM CDT Wed Oct 21 2026
Light east to southeasterly wind prevails in the west overnight with calm wind over the eastern half of the forecast area. The pattern of light wind continues into Thursday with speeds generally under 10 knots from the southeast along the Rio Grande and from the east to northeast at I-35 terminals. VFR conditions remain through the period except for a brief period of MVFR stratus near sunrise at KDRT.
