KEY MESSAGES

- Areas of dense fog across portions of the southeast Plains and into the San Luis Valley through the morning, keeping temperatures cool through the day.

- More low clouds and patchy fog across the plains later tonight into Monday morning.

- Quick moving system to bring snow to areas along and west of the ContDvd Tuesday and Tuesday night, with breezy downslope flow keeping warm and dry conditions across the plains.

- Another passing system to bring unsettled weather to the higher terrain of the ContDvd later Thursday and Friday.

SHORT TERM /THROUGH TONIGHT/

Issued at 1233 AM MST Sun Nov 15 2026

Current water vapor imagery and upper air analysis has broad upper trough translating across the Rockies with a weak circulation evident across the western Texas and Oklahoma Panhandle at this time. Said weak upper low is keeping some showers rotating across the plains late this evening, with generally light upslope flow keeping stratus and dense fog across the plains, especially across El Paso County, at this time.

For today and tonight, the Rockies broad upper trough and Western Panhandle low continue to translate east, with weak north to northwest flow aloft in place across the region through Sunday night. Movement of the weak upper low will continue to rotate a few showers across the far southeast plains through the early morning hours, with light moist low level upslope flow remaining across southeast Colorado as well. This will keep areas of fog, locally dense, through the early morning hours, with stratus expected to slowly clear from west to east through mid morning and into the early afternoon. With that said, we will keep the current Dense Fog Advisory in place for El Paso County through 9 am. Later shifts may need to expand it further south and east across the plains and possibly for portions of the San Luis Valley, if mid and upper level clouds clear faster than anticipated, or there is not enough mixing with the passing showers across the plains to help prevent dense fog development.

The slow decrease in stratus and fog will keep temperatures on the cool side Sunday, with highs in the mid to upper 40s expected across the plains, and in mainly in the 40s and 50s across the higher terrain, save for 30s at the peaks. With persistent weak low level upslope flow, latest model data indicates stratus and patchy fog redeveloping across the plains Sunday night, with expected overnight lows in the 20s and 30s areawide.

LONG TERM /MONDAY THROUGH SATURDAY/

Issued at 1233 AM MST Sun Nov 15 2026

Weak west to northwest flow aloft transitions to more southwest through the day Monday, ahead of our next weather maker digging across the West Coast. Dry weather remains on tap for Monday, with patchy fog and stratus diminishing through the morning across the plains, as some high level waa clouds spreads in from west to east across the area through the afternoon. High temperatures also warm slightly into the 50s across the plains and mainly 40s and 50s across the higher terrain. The slow increase in southwest flow helps to develop lee troughing across the plains Monday night, with lows in the 20s and 30s once again across the region, warmest in the banana belt, with developing westerly flow will keep temperatures up overnight.

For Tuesday and Wednesday, latest operational models and ensemble data are in good agreement of increasing southwest flow aloft through the day Tuesday, as the West Coast upper trough translates across the Intermountain West and Great Basin. This will start to bring some moisture into the Continental Divide with increasing chances of precipitation through the day. Moderate west to southwest flow across the region Tuesday night into Wednesday as said broad trough continues to translate east across the Rockies and into the high plains, will keep the best precipitation coverage across the higher terrain, mainly along and west of the Continental Divide Tuesday night, with precipitation diminishing behind the passing system through the day Wednesday. The quick movement of the system will limit precipitation totals, with the potential for low end advisory snow amounts possible, mainly across the eastern San Juan mountains.

The increased downslope and mixing will help boost temperatures back above seasonal levels in the 60s across the plains both Tuesday and Wednesday, with the potential for stronger westerly winds in the lee of the eastern mountains Tuesday night into early Wednesday morning.

For Thursday through Sunday, operational models and ensemble mean data continue to trend further north and not as deep with the next eastern Pacific system digging across the Great Basin and lifting out across the Northern Rockies. This will keep the best chances of precipitation once again along and west of the Continental Divide Thursday night through Friday night, with moderate to strong westerly flow keeping generally warm, dry and breezy conditions in place across the eastern Plains. Moderate north to northwest flow behind the passing system to keep slightly cooler and mainly day conditions across the region for Saturday and Sunday.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1021 PM MST Sat Nov 14 2026

At KCOS, kept VLIFR through the night, with some slow improvement starting 12z-16z, before clouds/fog dissipate around 18z. VFR then expected for the remainder of the day, but fog may make a quick return Sun evening, with IFR conditions after 03z.

At KPUB, IFR to LIFR conditions will persist through the night, with vis gradually lowering to 1sm after 08z. Slow improvement in the morning starting 12z-16z, then conditions become VFR toward 18z. Fog may return Sun night, but likely not until after 06z.

At KALS, expect IFR conditions after 07z as low clouds/fog develop across the valley. IFR lingers until 17z, then clouds/fog dissipate and VFR conditions return for Sun afternoon/evening. Fog may return again Sun night, but likely not until after 06z.

PUB WATCHES/WARNINGS/ADVISORIES

Dense Fog Advisory until 9 AM MST this morning for COZ084-085.
