A significant winter storm with snow, hail and cold

A low pressure system currently over the Central Plains begins to dive into the lower Mississippi Valley area on Friday night. Saturday, it rotates slowly to the southeast and eventually moves north along the eastern coastline.

Rain, snow, hail, or frozen rain – how about all of them in a 24-hour period. The same is going to happen in some states this weekend.

The storm will move through parts of the Midwest and the middle Mississippi Valley today, dropping up to a foot of snow.

Winds will also blow in these areas, which will cause snowfall and reduce visibility.

“The impact of travel is expected to be significant at times, particularly during afternoon school departures and evening commutes,” the National Weather Service (NWS) office in Des Moines said.

Parts of the Dakota, Iowa and Minnesota will receive heavy snow and 6-12 inches of snowfall is likely.

From there, the system continues to move deep south into Missouri, Arkansas and Kansas.

“How fast surface temperatures drop below freezing, and therefore, how fast rain turns to snow, will play a large role in determining how much snow accumulates,” said the NWS office in Topeka, Kansas. said.

The Southeast Gets a Mix of Everything

In many areas of the Southeast, this system starts as rain on Saturday.

As the temperature drops, that rain turns into freezing rain, hail, and eventually snow in many places.

Predicting winter weather in the Southeast is never easy, as times often turn bad.

“These different winter types are very sensitive to small changes,” said meteorologist Kyle Thiem of the NWS office in Atlanta. “A change of just a degree or two can mean the difference from relatively harmless precipitation to very impressive snow and ice accumulations.”

However, it is this system’s slow-moving motion that provides the setup for a terrifying snow storm that could cause millions of people to be struck by lightning.

The Carolinas will be the most likely region to experience snow, with cities such as Charlotte and Columbia picking up up to half an inch of snow, which will bring down trees and power lines along with strong winds.

The NWS office in Greenville, South Carolina, is warning that snow accumulation will become very dangerous east of I-85 and including Spartanburg, South Carolina, all the way to Salisbury, North Carolina. This includes the entire Metro Charlotte area.

In the southern Appalachian Mountains, snow totals will go up as quickly as possible. For example, Asheville, North Carolina, is estimated to rise 8-12 inches, but can rise as high as 20 inches at elevations above 4000 feet.

Mid-Atlantic and Northeast

The storm will turn toward the East Coast on Sunday and Monday, with some places likely to receive more than a foot of heavy snow.

The major metro areas of Washington, D.C., Philadelphia, New York and Boston will see some snow, but a change in rainfall will stop the accumulation.

“At this time, the most likely scenario is a massive outburst of snow on the front end for most of the day as the storm moves into the area on Sunday afternoon, followed by snow during the evening and possibly normal rain in areas near and east of I- is. 95,” the NWS office in Baltimore said Friday morning. “At this time, the icing is not expected to reach our far western regions, where heavy snow of a foot or more is possible.”

Interior cities like Charleston, Pittsburgh, Buffalo, Syracuse, and Burlington, Vermont will see the heaviest snow.

What helps the Northeast is that long before the heavy snowfall, there will be very cold air and dangerous winds blowing.

Wind chill alerts are in effect for more than 20 million people on Friday and Saturday, as it looks like temperatures could drop to minus 40 to 45 over most of New England’s interior.

“The chill of dangerously cold air can cause frostbite on exposed skin in as little as 10 minutes,” warns the NWS.
