.DISCUSSION, Issued 917 PM MST Wed Nov 4 2026...

Weak ridging has moved into Utah and southwest

Wyoming this evening as the storm system that moved through

earlier currently spinning over Colorado. With the influence of

that storm system, temperatures have stayed on the cool side, with

maxes averaging 5-10F below seasonal normals. 



High clouds will be on the increase tomorrow as weak shortwave

energy from the southern branch of a splitting Pacific Northwest

storm system tracks across the area through early Friday. Guidance

is overall trending even weaker with this feature, with any

potential for showers with this wave quickly dwindling. Its

presence will act to limit warming over the area, however, with

persistence being the name of the game through Friday.



Behind that weak wave, strong ridging off the Pacific coast will

continue to build through at least early next week. This will

bring a steady warming trend over the weekend, resulting in

temperatures up to 5F above seasonal normals by Sunday, with the

potential for mild temperatures to continue for much of the

upcoming week. Compared to yesterday, guidance seems to be

trending toward solutions that favor the persistence of that

blocking ridge for much of the upcoming week. A minority of

solutions, however, including several GFS members, break down the

ridge by midweek, allowing for a more active pattern to develop

once again. Therefore, confidence in the forecast as day seven

approaches remains low.
