In a 24-hour span, temperatures that climbed to around 60 degrees in parts of the region during the storm will plummet after Arctic air and brutal winds set in starting late in the afternoon on Christmas Day, Friday, Dec. 25.
That's when temperatures will fall from the mid 50s to the low 40s, with wind-chill values making it feel even colder.
There will be a chance of showers through 9 p.m., followed by a slight chance of snow showers between 9 p.m. and midnight.
It will be much colder overnight, with the low temperature in the mid 20s and wind-chill values between 15 and 20 degrees.
Saturday, Dec. 26 will be mostly sunny with the high temperature only around 32 degrees and wind-chill values between 15 and 20.
Parts of the region will see a 30-degree temperature drop in just one day. (See images above.)
