"That front is clearing the area now," said AccuWeather senior meteorologist Steve Wistar, adding, however, that it is opening the "floodgates" to ridiculously cold weather. "The failing snow is ending, but the blowing snow continues."
Tonight, 1 to 2 inches of snow is expected and temperatures are likely to drop to 7 degrees below zero. The National Weather Service has issued a winter storm warning for all suburban counties, effective until 6 a.m. Monday due to the snow and wind.
Temperatures will stay in the minus 5 to minus 10 degree range during the morning commute on Monday, Wistar said, adding that later in the day it is expected that they will drop lower than they did on Jan. 6.
"This actually may be colder than that by a few degrees," Wistar said, referring to the -16 degrees that was recorded three weeks ago.
With wind gusts expected to range from 12 to 25 mph on Monday, the wind chill will be 20 to 25 below zero, Wistar added. A wind chill warning will be in effect from 3 a.m. Monday to 9 a.m. Wednesday.
