The weekend will start seasonably cool Friday and Saturday, and then turn even colder Sunday as a polar air mass moves into Wyoming and Colorado from the north. It looks like daytime temperatures will below freezing in the low elevations on Sunday and Monday.
If you are traveling north and east into Nebraska and the far northeastern plains of Colorado (east of Sterling), or up into central Wyoming, snow and blowing snow will make for difficult travel tonight through Sunday. For the Front Range region no major precipitation is expected for the eastern foothills and adjacent plains, but periods of clouds and some minor precipitation is possible.
The first chance of precipitation is this afternoon and tonight. Light snow accumulation is likely in the high mountains and west-facing slopes. Watch for icy conditions at the passes tonight and tomorrow morning. For the urban corridor some rain or snow showers will be around, but little or no accumulation of snow is expected. The next chance of snow for the eastern foothills and nearby plains is Sunday afternoon or night. Only light accumulations around and inch or less appear likely right now.
