Saturday: Even colder morning with air temperatures around five below zero. Wind chill values will range from -10 to -20. Wind chills will climb above zero into the afternoon. Highs reach into the lower teens with more sunshine.

Sunday: Cloud increase quickly ahead of a system that may bring mainly snow, perhaps some sleet or rain mixing into the evening and overnight. A push of warmer air arrives ahead of this system, and temperatures may reach to around 30 degrees. It’s this bump in temperatures that could allow for some wintry mix with the snow initially before changing over to all snow.

Monday: Temperatures will be hovering around freezing with snow falling. Some mixing may begin as temperatures slowly climb. Might briefly change to rain in the afternoon as we push to the mid to upper 30s. Due to the long stretch of cold weather leading up to this storm, it’s important to note that road temperatures may lag in the warming process and initially if we change to rain, the road may still be cold enough to stay icy. Temperatures drop quickly into the night. 

Tuesday: Partly sunny and colder with morning lows in the 20s and highs around 30 degrees.
