UPDATE via Accuweather:
The weather will change in dramatic fashion with a rapid freeze-up anticipated across portions of Midwest and interior Northeast due to a multifaceted storm that will continue to push across the country from Thursday night into Friday, AccuWeather meteorologists warn.
Temperatures have already plummeted from springlike levels on Wednesday into the 20s across parts of the central United States as a snowstorm created slippery travel conditions.
"We are turning the clock back to January in the central United States on Thursday and Thursday night and will do the same in the Northeast on Friday," AccuWeather Chief On-Air Meteorologist Bernie Rayno said.
After surging to levels more typical of April in many areas, temperatures are forecast to plummet to 10-20 degrees or more below average for mid-February from west to east across the Plains, Midwest and Northeast into Friday.
As temperatures plunge from west to east, areas of standing water, slush and moisture will freeze unless treated with significant ice-melting compounds. On top of that, many crews may not be able to successfully pre-treat roads as rain will quickly wash away chemicals used to melt snow and ice.
