Updated at 503 AM MDT Mon Oct 6 2025 - Temperatures remain a few degrees above normal through the week. - Low chance of showers and thunderstorms for the middle part of the week, favoring northern areas. && .DISCUSSION... Issued at 1016 PM MDT Sun Oct 5 2025 Positively tilted trough continues from central Canada down across the Great Basin to central California. This has allowed a rather persistent dry, southwest flow over the CWA for several days. Models do continue to show moisture advection beginning Monday night and more in earnest Tuesday and Wednesday. Hurricane Priscilla, thought not sharing any moisture with us (yet) is helping the upper pattern by allowing sub-tropical high to build back over northern Mexico. This will allow mid-level (700-500 mb) flow to turn more south/southeast and bring moisture in. At the surface the east/southeast flow brings a dry (wet) line in, again somewhat on Monday night but more significantly on Tuesday. Thus a few showers/thunderstorms could break out east of the RG Valley late Monday afternoon and evening. Some of the CAMS models show this solution. Grids are starting to reflect this, though future shifts might want to increase this. Expect some POPs through Wednesday night. Thursday and Friday...sub-tropical high continues building west and centering over west Texas by later Thursday into Friday. This should help push the main moisture plume north and west of the CWA, allowing POPs to approach zero. Saturday through Monday...the last short-wave or two out of the positively tilted trough is able to bang into the Mexican high and begin displacing it eastward some. Thus, the main moisture plume migrates eastward back over the CWA, for increasing chances of showers/thunderstorms. Some difference between GFS/ECMWF with timing. ECMWF is earlier, suggesting rain could develop Saturday afternoon while ending by early Tuesday morning. On the other hand the slower GFS begins the rain out west Sunday afternoon and spreading eastward later in the day, and lasting well past Monday. GFS also more explicit than ECMWF in showing moisture from next tropical system (Raymond) playing a role in our weather after Sunday night. && .AVIATION...
