.Forecast Summary...It'll be mostly clear and seasonably cool tonight. High pressure will be over the area tomorrow. A shift to winter weather will take place this weekend. The first in a series of Pacific storms will bring an increase in clouds and wind. Rain with higher elevation snow will develop on Monday as the storm moves through. Another storm will arrive mid-week accompanied by more wind and precipitation. The snow level currently looks to be near 6000 feet on Monday then lower to 4000 by Wednesday. This should result in a significant snowfall for the mesas and mountains. Temperatures will also cool to below normal levels for next week.
