A burst of arctic air and two rounds of snow are expected in the week leading up to Christmas, according to the National Weather Service.

Light snowfall is expected today, with widespread amounts between a trace-to-one inch likely by Tuesday morning. Behind that snow will be colder conditions, with highs primarily in the teens and overnight lows dropping into the single digits Tuesday and Wednesday. Travel may be difficult at times this evening.

Another round of snow is in the forecast starting Wednesday afternoon and continuing through Friday morning. A winter storm watch has been issued starting Thursday morning and continuing through Friday evening. Gusty winds will be coming along with that storm, causing more travel concerns, and initial forecasts indicate more moderate accumulation is possible.

Extremely cold conditions are expected to end the week, with wind chills ranging from 20 to 30 below zero Thursday through Saturday. Frostbite and hypothermia can occur in as little as 30 minutes without proper precautions in those conditions.
