UNSEASONABLY WARM AND MOSTLY DRY THROUGH THE WEEKEND:

With high pressure in place across the Southwest, warm and dry conditions will be favored through the weekend. Temperatures will range from 5 to 15 degrees above normal across the region. A mild boost in moisture Sunday afternoon could lead to isolated convection over the San Juans, but without much else driving active weather, the vast majority of the region should anticipate a dry weekend.

WORK WEEK OUTLOOK:

Looking ahead to next week, high pressure breaks down late Monday into Tuesday as a shortwave trough advects through the northwesterly flow. This could again prompt terrain-based showers, but with dry surface levels in place, measurable rainfall could be hard to come by. Beyond this weak disturbance, high pressure and warm and dry conditions remain the name of the game through the work week.
