According to the National Weather Service, A low pressure system and an associated cold front will move through through the region tonight, followed by an upper level disturbance on Tuesday. This will lead to an increasing chance of snow showers and some patchy freezing drizzle later tonight with more widespread snow showers continuing during the day on Tuesday.
Behind the cold front, a much colder airmass will move into the area on Tuesday with temperatures falling into the 20s through the day. Northwest winds will also increase to 15 to 25 mph with gusts of 30 to 40 mph possible. This will lead to occasional snow squalls through the day with a quick 1 to 2 inches of accumulation possible. Rapidly changing visibilities will also be possible with brief near whiteout conditions possible.
If you are planning travel late tonight and through the day on Tuesday, be prepared for icy roads and rapidly changing driving conditions.
