      Early morning temperatures in the single digits will struggle to climb above the teens today despite lots of sunshine. But a biting northwesterly wind will make for dangerous wind chills from 5 to 20 degrees below, possibly even colder in the mountains west, to start the day.

      High pressure will build overhead for mid-week calming the blustery wind. Highs back to near freezing Wednesday will climb into the low to mid 40s for the end of the week with some added clouds.

      Rain is possible by the end of the week. Please be safe and remember to layer up if you must be outside for extended periods of time. Have a great day!
