.DISCUSSION... Issued at 1050 AM MDT Wed Oct 1 2025
Flat zonal flow with an UL high over Mexico will keep us dry and warm today. This UL high will slowly build north through the remainder of the week, keeping us dry and warm. The high will center itself over us by Thursday before shifting into the Southern Plains on Friday. The eastward shift of the high will be courtesy of a sharply digging UL trough along the West Coast. Deepening southerly and southwesterly flow will allow subtropical moisture to flow northward. The GFS shows isolated to scattered QPF along the Arizona border Friday afternoon and evening, but the NBM is not buying this solution.
The UL trough will continue to broaden throughout the weekend with NM coming under increasing influence of the trough. An embedded s/w within the growing long-wave trough will cross just north of the Four Corners into CO on Saturday. Lee troughing will develop, increasing our winds to the low-end breezy category as well as shifting direction from southeast to west, especially west of the Rio Grande. According to the Euro, this trough passage will also sweep out our moisture though the GFS keeps meager moisture around without any QPF.
As we go into next week, our subtropical moisture tap begins to get reestablished. The GFS is the most aggressive with this tap bringing QPF to areas west of the Rio Grande, but the NBM holds low POPs to only our mountain regions. Just beyond the forecast window, both models show our weather coming under the influence of what would be "Priscilla" in the East Pacific for mid to late next week. Presently NHC has not assigned an Invest number to the tropical wave, but does label the area with an 80% chance of formation within the next 7 days.
