SHORT TERM /THROUGH TONIGHT/

Issued at 1232 AM MDT Sat May 2 2026

Currently...clouds across region continue to dissipate with mostly clear skies expected into Saturday morning. Temperatures will continue to cool, with lower to mid 30s across the Plains by morning. This will lead to areas of frost on the Plains, and sensitive vegetation may be harmed through the morning hours. There could also be areas of patchy fog across the San Luis Valley through the early morning hours.

Today and tonight...upper level high pressure is forecast to build across Colorado through tonight, while weak energy over the Four Corners region slowly drifts south into New Mexico. Overall, it will be a very nice day across southern Colorado. Afternoon high temperatures will reach into the 60s and 70s across the Plains, while the San Luis Valley reaches the upper 50s to lower 60s. A few rain and high elevation snow showers will be possible this afternoon and evening, mainly across the San Juan Range. Snow levels will be confined to above 10 kft, where a light dusting of snow may be possible. Any showers that do form, may be able to produce a very isolated lightning strike. This activity will dissipate this evening, with dry conditions prevailing into Sunday morning. Overnight lows tonight will fall into the upper 30s to lower 40s across the Plains, while the San Luis Vally falls into the 20s and 30s.

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 1232 AM MDT Sat May 2 2026

Models in very good agreement through the extended period, with an active pattern mid week across southern Colorado. This includes cooler weather, rain and snow chances Tuesday into Wednesday.

Sunday into Monday...upper level ridging will sit across Colorado on Sunday, while two upper systems, one over Canada, and a second off the West Coast, begin to move towards the area. Overall, dry conditions will prevail on Sunday, with a very low chance of isolated showers along the Continental Divide. Temperatures will also continue to warm, with 70s and 80s for highs for the lower elevations. By Monday, the upper system over Canada will begin to push south, while the west coast system moves into the Great Basin. Westerly flow will increases ahead of the Great Basin system, with a few areas along the New Mexico border approaching critical fire weather conditions. Temperatures will remain warm, with 70s and 80s across the Plains. An embedded upper wave will lift northeast across western Colorado into northeastern Colorado late Monday afternoon and overnight. This will spread showers from the Continental Divide, northeast across the Palmer Divide into northeast Colorado Monday night.

Tuesday into Wednesday...the two upper systems are forecast to interact with each other for the mid week period. The northern trough will end a cold front south across the Plains Tuesday morning, with northeasterly upslope flow developing across the Plains. Aloft, the Great Basin system will send moisture north across Colorado. Colder air willa advect southward lowering snow levels Tuesday night into Sunday morning to near 6000 ft by Wednesday morning. Precipitation could be heavy, from the Palmer Divide, south along the Eastern Mountains, and into the Raton Mesa Tuesday night into Wednesday morning. Lowered temperatures on Wednesday, but still may need to come down more (wouldn't be surprised to see highs on Wednesday in the 30s and 40s). A secondary surge from the north will arrive on Wednesday, with continued widespread precipitation across the Plains. At this time, QPF amounts are nearly and inch, but will most likely be adjusted over the next couple of days. For those above 6000 feet, dense wet snowfall could accumulate on trees and powerlines causing damage. Precipitation looks to come to an end Wednesday night into Thursday morning, as the upper trough shifts east.

Thursday into Friday...upper ridging is forecast to rebuild across the western states, while trough shifts to the east. This will put southern Colorado under broad northwesterly flow aloft, with a few light snow showers during this period over the Central Mountains. Temperatures will also begin to rebound with 70s to 80s by Friday.
