Our next arctic blast arrives by the end of the week

Tonight:  The clouds will decrease during the night with low temperatures falling into the single digits and teens for most areas with the high mountain valleys falling below zero again.

Extended:  Monday looks less cloudy; more clouds are expected Tuesday and Wednesday. High temperatures through mid-week will generally reach the 30s and 40s along and west of the I-25 corridor, but Tuesday could be colder over lower elevations farther east. Very cold air looks to reach the area late Wednesday and early Thursday possibly resulting in some light snow, and we’ll remain very cold over much of eastern Colorado on Friday while the air over and near the mountains should warm a little.
