Don't be caught off guard on Monday. A very strong arctic cold front will push south across our region Monday morning.
Especially for those further south, you may wake up to mild temperatures Monday morning, but don't be fooled. The weather will be very different at the end of the day.
Expect temperatures reaching the single digits or even below zero by Monday evening with snowfall increasing in coverage through the afternoon.
Widespread subzero lows are expected Tuesday morning. Brutally cold temperatures will remain entrenched through Thursday.
