- Large temperature gradient across the area over the weekend, with colder temperatures generally east of Highway 83/23 and milder temperatures in Colorado.

- Fog and freezing fog return to western areas Saturday night and Sunday morning.

- Milder temperatures in the 50s, 60s, and maybe 70s return next week with some fire weather risks.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 1254 AM MST Sat Dec 13 2025

Fog and freezing fog will continue through the overnight. Dense fog has been rather patchy thus far, but will continue to monitor observations since models suggest it may become more widespread. After 12z, surface winds turn west then northwest in western 2/3rds of the area (generally west of Highway 83), which will scour out the low clouds and fog, but it will take a little longer further east. The far eastern areas (McCook, Norton, Hill City) may be stuck in the clouds all day, which will impact high temperatures. Highs there will struggle to reach the middle 30s, while in western areas highs will be in the 40s and 50s. The low clouds get pushed south this evening by brisk northeasterly winds, but after 06z the winds turn to the south which will allow the low clouds and fog to return to the area. Models currently show the favored area for fog west of Highway 25 including northeast Colorado, persisting into Sunday morning. Low temperatures will generally be in the teens. The large temperature gradient sets up again for Sunday afternoon with the stubborn shallow cold air mass east of Highway 25 keeping temperatures in the 30s while western areas see highs in the 40s and 50s. Shortwave ridging will move in from the west on Monday with milder temperatures for the entire area. Highs will be in the upper 50s to lower 60s. Afternoon relative humidity minimums will drop into the teens in Colorado and mixed layer winds show gusts up to 20 kts possible in that area. Since both parameters will be marginal at best, elevated rather than critical fire weather conditions will be possible. Lows Monday night will be in the 20s and 30s.

LONG TERM /TUESDAY THROUGH FRIDAY/

Issued at 1254 AM MST Sat Dec 13 2025

Zonal flow will be in place across the CONUS. An embedded shortwave trough will move through Wednesday night, but does not have enough moisture for a precipitation threat and the forecast remains dry. Temperatures will be much above normal Tuesday and Wednesday, with highs in the 60s and higher percentiles showing 70s possible, which could be in record territory. Afternoon relative humidity minimums will drop into the teens both days with a fire weather risk. Mixed layer winds on Tuesday look marginal though possibly could see gusts up to 25 mph. Winds appear to be more favorable for Wednesday. A brief cool down will occur on Thursday behind the shortwave with highs around 50. The cool down will be brief as temperatures on Friday bounce back into the 60s/70s with another fire weather day possible due to low humidity and marginally favorable mixed layer winds.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 412 AM MST Sat Dec 13 2025

IFR conditions will persist into early this morning at KGLD due to low clouds and fog, but will return to VFR by around 15z with northwest winds scouring them out, at least temporarily. Another surge of low level moisture this afternoon from the northeast will bring the low ceilings back to KGLD around 21-22z this afternoon, which will persist through the remainder of the TAF period Saturday night. Fog may also develop Saturday night.

KMCK will see IFR conditions continuing through most of today. Some gradual improvement in visibility will be possible by this afternoon, but the low ceilings will persist. Saturday night, a return to VFR is possible as the low ceilings and fog shift westward.
