The storm is predicted to affect millions of people as it makes its way from the West Coast to New England.
The National Weather Service (NWS) in Pittsburgh issued a winter storm warning for the area that went into effect Friday.
Lee Hendricks, NWS spokesman, said Fayette County residents can expect to wake up to rain and sleet Sunday morning, with possible snow accumulations in the afternoon.
Hendricks said the storm system is actually bringing in milder temperatures that will hit the mid-30s before falling into the upper 20s throughout the afternoon and late evening.
Hendricks said the snow is expected to taper off into flurries late Sunday night into Monday morning with temperatures dipping down to 5 or 10 degrees in the evening.
According to Hendricks, the remainder of the week appears to be dry until Thursday.
Polk County is currently under a winter storm warning, as snow moves across Iowa, targeting the area around 8 p.m. tonight.
Snow will continue throughout the night, becoming heaviest after midnight, said Craig Cogil, meteorologist with the National Weather Service’s Des Moines office.
Travelers can expect poor visibility on the roads overnight. In addition, winds sustained at 15 to 20 miles an hour with gusts between 25 and 30 miles an hour can cause accumulated snow Sunday to drift.
With temperatures Saturday and Sunday around 20 degrees and dropping off from there, the snow is expected to stick around for a possible “White Christmas.”
“At this point in time, it sure looks like it,” Cogil said.
The Iowa State Patrol is preparing for the severe weather by extending troopers’ shifts and widening their assigned patrol areas to help stranded motorists,according to a news release. If necessary, the State Patrol will request support from the Iowa National Guard.
For people who are traveling during the storm, the State Patrol offers the following tips:
– Allow proper stopping time by increasing the following distance
– Do not use cruise control on snow or ice covered roadways
– Use caution on overpasses, bridges, and all ramps
– Be alert and focused on driving
– Allow extra travel time
