Storm will promote wintry precipitation over Nebraska and Kansas by midday on Friday before overspreading Missouri and southwestern Illinois that evening. Snow will swing down across the Plains and into the Ohio River Valley before moving off the mid-Atlantic coast.
AccuWeather Global Weather Center – February 13, 2019 – A quick-hitting winter storm is expected to sweep through the United States at the end of the week, dropping a sheet of snow over areas from the Plains to the mid-Atlantic.
High pressure over the southern U.S. will maintain dry and seasonable conditions in the region through midweek before a small storm develops over the Plains on Friday.
"Snow will swing down across the Plains and into the Ohio River Valley before moving off the mid-Atlantic coast," said AccuWeather Meteorologist Brett Edwards.
The storm will promote wintry precipitation over Nebraska and Kansas by midday on Friday before overspreading Missouri and southwestern Illinois that evening.
"Any snowfall can create slippery road conditions and result in travel delays," Edwards warned.
While snow is not expected to last longer than 12 hours in any one location, several inches of snow can accumulate in that time. The Friday evening commute in Kansas City and St. Louis could face major delays as roads quickly become slick and snow covered.
On the southern edge of the snowfall, a mix of snow, sleet and freezing rain is expected. This can lead to a narrow swath of treacherously icy conditions.
Overnight, an area of wintry mix and heavy snow will sweep through the Ohio Valley. Residents of areas from Louisville, Kentucky, to Cincinnati and Huntington and Charleston, West Virginia, could wake up on Saturday morning to a layer of fresh snow.
Flakes will then fly on Saturday across the mid-Atlantic, including Philadelphia, Washington, D.C., and Baltimore. These cities could receive a few inches of snow, sending people out with shovels on Saturday evening and Sunday morning. New York City may be on the northern edge of the snow.
"While totals will not be very high, many roads will still likely be snow packed and slick," Edwards said.
Friday night into Saturday, heavy rain on the southern half of this system can exacerbate flood concerns throughout the Tennessee Valley and central Appalachians.
