.DISCUSSION... Issued at 1003 PM MDT Thu Oct 2 2025
Pretty quiet start to the forecast period as high pressure and/or dry southwest flow aloft dominates. Then some "noise" enters mid portion of next week. For tonight and Friday, Mexican high pressure ridge that has built over New Mexico begins to drift east in response to Pacific trough moving in. However main result is still dry southwest flow aloft over the CWA. Models do continue to show a sliver of moisture being drawn northward in this flow over the area, and with some of the CAMS models showing showers/tstms late afternoon and evening Friday, have put low POPs in grids west of the Cont Divide to reflect this. Otherwise dry through Monday with high temps about 5-7 degrees above normal.
Things get interesting Monday night and beyond. What will be tropical Priscilla moves up toward the southern Baja. While her moisture contribution is minimal, she pushes much of the dry southwest stream over us to our northwest and allows mid level south/southeast flow to advect sub-tropical moisture into our area. By Monday night and Tuesday, dewpoints increase back into the 50s across the CWA and pretty much remains in place the remainder of next week. Also by Monday night and Tuesday, PWs are back over an inch after ranging in the .5-.7 inch mark this weekend. Thus, POPs begin popping up many of the forecast zones Monday night. Priscilla sheds more moisture up Thursday and Friday but most of this looks to head into Arizona. Both GFS/ECMWF continue to move the last remnants of Priscilla up over Arizona though timing is significantly different. Because of this rain chances beyond Thursday still well up in the air.
