- Active weather returns to the region starting Sunday, lasting into next week.

SHORT TERM /THROUGH TONIGHT/

Issued at 1232 AM MDT Thu Oct 8 2026

Currently...Clearing skies across the forecast area late tonight, with temps forecast to drop into the mid 30s to around 40F for the high valleys, and into the 50s for the plains.

Today and tonight...Very similar day to yesterday expected, with high temps perhaps a degree or two warmer, and isolated shower and thunderstorm activity developing over the higher terrain through the afternoon and early evening. West to northwest upper flow across the region today, while a weak disturbance crossing the Great Basin will provide the upper level support for isolated convection. Main threats from any storms will be cloud to ground lightning and occasional gusts to 45 mph. Expect highs in the 70s for the high valleys, and upper 70s to upper 80s for the plains, which is about 10 degrees above seasonal normals. Overnight low temps will again drop into the mid 30s to mid 40s for the high valleys, and 50s for the plains.

LONG TERM /FRIDAY THROUGH WEDNESDAY/

Issued at 1232 AM MDT Thu Oct 8 2026

Friday...Upper flow across the region shifts to a more west to southwest direction, as a large Pacific trough begins to strengthen along the coastline of British Columbia and the Pacific NW. Meanwhile, another transient upper shortwave crosses the Four Corners region. Models indicate even more isolated activity for the mts during the afternoon, mainly tied to the Continental Divide, while temps across the eastern plains push upward to near 90 degrees for some spots. By late Fri night, the Pacific system starts to deepen and drop south along the West Coast, setting up for the weekend. Plan on highs in the 70s for the high valleys, and 80s to near 90F for the plains.

Saturday...Big changes in the upper pattern start to take place Saturday, as the Pacific low pressure trough digs even further south and absorbs the remnants of Hurricane Rachel. Deep southwest flow aloft develops across the Four Corners, feeding this moisture into western CO and dramatically increasing precipitation chances and coverage starting in the afternoon and lasting through the night. Meanwhile, Tropical Storm Simon starts to push north along the Mexico coastline. Forecast QPF totals through Saturday total to around .4 to .5 of an inch across the southwest mts, while the rest of the Divide receives lesser amounts. While the high valleys will cool a couple degrees due to increasing cloud cover and precip chances, the eastern plains will remain hot. Look for highs in the 60s to around 70F for the high valleys, and 80s to near 90F once again for the plains.

Sunday and Monday...Strong Pacific low system stays anchored along the CA coast both days, keeping strong southwest flow aloft over the Four Corners. The remnants of Simon slide north along the Mexico coastline and eventually get absorbed with the flow aloft and pushed into CO, continuing rainfall across all of the higher terrain but mainly focusing along the Continental Divide and the southern mts. Forecast QPF for the sw mts for both days equals to around an inch and a half of additional water, so a Flash Flood Watch may need to be considered on following shifts if the models remain consistent. As for temps, high valleys will see highs in the 60s both days which is right around seasonal normals, while the plains remain hot and above normal. A cold front late Monday evening across the eastern plains will bring a change to that, starting Tuesday.

Tuesday and Wednesday...A very active weather pattern through mid week, as the upper low finally moves onshore across CA and NV on Tue, then across CO on Wed. This path will bring widespread precip chances to all of the forecast area on Tue, and possibly through Wed. Look for significantly cooler temps as well, as the cold front late Mon evening combines with extensive cloud cover and ongoing precipitation. High temps both days will likely be in the 60s for the high valleys, and 60s to around 70F for the plains. Tue and Wed will be the time period for some snow across the mts as well, as snow levels finally begin to lower. Moore
