SHORT TERM /THROUGH TONIGHT/

Issued at 102 AM MDT Sun May 10 2026

Today: The end of the weekend will bring slightly active weather for the plains, with quiet weather for the valleys and mountains. Early in the day, a wave will be passing over the area, bringing an increase in broader ascent. Along with that, northeasterly to southeasterly surface winds, and an uptick in moisture, will be in place behind a cold front passage Saturday night. With the broader synoptic support, and at least modest surface upsloping, thick clouds and pockets of drizzle are expected tomorrow morning across the eastern plains. Any drizzle across the plains is expected to dissipate by early afternoon though as the wave starts to exit the region. Elsewhere though, dry conditions will prevail through the entire day. Beyond all of that, as alluded to, the plains will remain fairly cloudy through at least early afternoon, with skies steadily clearing thereafter, with mostly clear to partly clouds skies for the valleys and mountains. As for winds, breezy conditions early will give way to mostly light winds, around and less than 10 mph, during the afternoon hours. Looking at temperatures, with the cold front passage and thick cloud cover for a significant chunk of the day, the plains will be below seasonal values, with highs in the upper 50s to low 60s. The valleys and mountains on the other hand will remain near to above seasonal values, with the valleys in the upper 60s to low 70s, and the mountains in the mid 40s to upper 50s.

Tonight: Heading into Sunday night, quiet weather returns for all of south central and southeastern Colorado. Northwesterly flow will quickly develop behind the exiting wave. With subsidence and drier air filtering into the area, dry conditions are expected for the region overnight. Otherwise, skies will progressively become mostly clear, with winds remaining light, around and less than 10 mph. As for temperatures, with clearing skies and mostly light winds, much of south central and southeastern Colorado will fall to around seasonal lows. The plains will cool into the low to mid 40s, the valleys into the low 30s to low 40s, and the mountains into the mid 20s to mid 30s.

LONG TERM /MONDAY THROUGH SATURDAY/

Issued at 102 AM MDT Sun May 10 2026

Monday - Wednesday: For the early part of the week, quiet weather continues for south central and southeastern Colorado. At this point, ridging will be in place across the four corners region and will slowly drift eastward during this period. Confidence is very high (90%) in this pattern evolution given strong support from, and agreement within, ensemble model guidance. With the ridging in place, dry conditions are expected to prevail for the region. The exception to this may be along the mountains, where a highly isolated diurnally driven shower can't be ruled out. Outside of all of that, breezy afternoon winds with mostly clear to partly cloudy skies is anticipated, though with clouds starting to increase in coverage Wednesday ahead of an approaching pattern change. Temperatures during this period will be warm, with above seasonal values expected for much of the region.

Thursday - Saturday: Finally, heading into the later part of the week and start of the weekend, a pattern change arrives for south central and southeastern Colorado, with an uptick in active weather. The ridging in place will flatten out, with embedded waves passing over the region. Confidence is high (70-80%) in this pattern change, with continued support and agreement from ensemble models. This pattern will bring increased precipitation chances, but particularly along the mountains where forcing will be greatest. In addition, areas of critical fire weather conditions, at least meteorologically, may develop given the increase in periods of dry, downsloping winds with the more unsettled pattern. Beyond all of that, at least partly cloudy skies are anticipated, and as alluded too, breezy winds with the increased flow. Looking at temperatures, many will remain warm and above seasonal values.
