.SHORT TERM /THROUGH TONIGHT/... Issued at 204 PM MDT Tue Oct 7 2025
Stratus has been slow to break across much of the plains this afternoon and as we loose day time heating easterly upslope flow will push this back into the lower eastern slopes of the southeast mountains with clouds bases lowering overnight and some patchy fog possible in and near the upslope terrain region. Moisture looks a little more shallow with less upper forcing expected tonight so think we won`t see as much in the way of drizzle. Whee we could see some precipitation would be the southern mountains and southern San Luis Valley this evening as southerly flow is advecting higher dew points northward and a cu field is evident across Conejos and Costilla counties. Not expecting much moisture from these, and have trimmed northern extent of isolated pops southward quite a bit as odds look less favorable farther north. Otherwise, should see low temperatures a little warmer tonight across the southwest mountains and interior valleys as low level moisture increases. May even see some low clouds and fog develop towards dawn in the center of the valley and southwest slopes of the eastern San Juans though think this will still be fairly patchy in nature for one more night.
Upper ridge builds for Wednesday and southerly winds increase through the day. This should help erode stratus across the plains more quickly tomorrow morning with breezy southerly winds helping to provide sufficient mixing to bring a return of 70s to lower 80s for highs. Mountains and interior valleys should be similar to a degree or two warmer given rising heights aloft. South to southwesterly flow will continue to advect low level moisture northward which should yield isolated to scattered afternoon and evening showers and thunderstorms across the southern mountains as a tropical moisture fetch gets tapped. Will be watching what happens as moisture from the remnants of hurricane Priscilla continues to spread in from the south. Precipitable waters well ahead of Priscilla climb to near 150% of normal in ensembles by Wed afternoon across the eastern San Juans, so as time goes on, main thunderstorm risks will trend towards heavy rainfall. -KT

.LONG TERM /WEDNESDAY THROUGH TUESDAY/... Issued at 346 AM MDT Tue Oct 7 2025
Thursday Onwards...
The warming trend will continue into the latter half of the week, with the upper ridge continuing to build overhead. High temps will climb into the mid-80s over the plains, with the area remaining generally dry outside of some scattered POPs in our western mountains. As we move into the weekend, the high pressure to our south will begin pushing more east, while a deep closed low moves onto the west coast. Meanwhile, the remnants of a tropical cyclone will push up the western coast of Mexico, injecting more moisture into the synoptic flow. Beyond this point, model solutions begin to diverge, handling the evolution of this complex pattern in different ways. Overall, trends have shown for a cooler, wetter, and generally more active weather period later this weekend and into early next week.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 517 PM MDT Tue Oct 7 2025
MVFR and IFR stratus expected to fill in at COS and PUB through the evening hours, with light easterly upslope flow persisting through the overnight hours. Southwest flow aloft will develop lee troughing and southwest surface flow with stratus diminishing and VFR conditions developing by 14Z and persisting through the rest of the taf period.
Primarily VFR conditions expected at ALS over the next 24 hours, with breezy southwest winds diminishing this evening. There is a low end chance of MVFR/IFR stratus early Wednesday morning. Otherwise will see breezy southwest winds developing once again aft 18Z.
