Wednesday afternoon observations show cloud cover and convective precipitation increasing over western Colorado. A progressive shortwave trough embedded in the northwest flow will be our primary storm feature during the next 24 hours. I expect rain and snow showers to increase in both coverage and intensity this afternoon in advance of a cold front currently tracking through Utah. Showers will steadily progress south Wednesday night, with overnight temperatures in the low 20’s.
By noon on Thursday, higher elevations of the Park Range and Flat Tops could see more than a foot of new snow. For other areas in the Northern and Central Mountains, I expect 4 to 9 inches of new snow, with localized higher totals. Elsewhere, look for 3 to 5 inches of new snow as far south as the Northern San Juan Mountains.
After a brief lull, mountain winds back to the west/southwest Thursday evening, as yet another upper-level feature carves out a trough over our region. Mid-range models show upper-level low pressure cutting off and closing off somewhere near south central Colorado / northern New Mexico on Friday. This evolution will bring a heavy dose of precipitation to the eastern mountains of Colorado into Saturday. Mid-range models continue to iron out details concerning the track and specific impacts from this storm feature.
