After a brief warm-up late this week, we are heading back to some very cold air by the end of this weekend.
Highs today will be near freezing, but quickly tail off after dark. Some patchy ice is possible as water standing from Friday's rain freezes.
Arctic air really takes hold Sunday with highs in the teens. Lows will be in the single digits several mornings this week. Wind chill values may dip below -10 Monday morning.
