Maps showing snow storm forecast like Midwest and East Coast Brace for winter weather

A procession of winter storms continued across the United States on Tuesday, threatening more than 80 million from the midwest to the East Coast with a mixture of potentially severe weather.

“A winter storm brings strong snow and ice to the Ohio Valley into Mid-Atlantic through Wednesday,” National Weather Service said. “Significant ice is expected for the central Appalachians. Another winter storm will bring heavy snow and ice to the central plains today.”

Forecast cards show the trails and possible effects of two strong weather systems that are expected to cause winter extremes this week in several regions.

The second winter storm of the week traveled from the Mississippi Valley into the middle Atlantic region early Tuesday morning, with a seizure of cooling temperature.

Some communities in the path to a storm supported another weather system to arrive on its heels, which the National Weather Service called “significant.” CBS News -Meteorologist Nikki Nolan said a storm would probably trace northeast of the large plains affecting places in the Midwest and northeast Wednesday and Thursday.

“The storm will produce heavy snow from northeastern Kentucky into West Virginia through the I-95 corridor from Richmond to Philadelphia,” Weather Service said in advice on Tuesday morning. “Snowfall speeds sometimes reach 1 inch per hour, with heavy, wet snow-hotels of 4-8 inches expected. Isolated power cuts are possible and traveling can become extremely dangerous (especially during commuting on Tuesday night).”

Snow, gossip and ice were expected on the northern side of this week’s storms, while potentially severe, heavy, heavy rain on the south side.

Various weather alerts were set to remain in place for large parts of the eastern United States for Thursday, when forecasters said the next winter storm could blanket wide ribbons in the country with up to 10 inches of snow. Extreme cold warnings and advice on cold weather were issued further in parts of the northern rockies, the large lakes and central plains regions due to an Arctic front driving temperature down to 25 to 35 degrees below average.

Weather services in Chicago and Hastings, Nebraska, urged people to prepare for at least 6 or 8 inches to gather, and parts of central Virginia and West Virginia were preparing up to half an inch of ice. National forecasters warned that excessive rainfall would increase the risk of flooding of flash and flooding of the river in parts of the lower Mississippi and Tennessee Valleys as well as the southern Appalachians.

Forecasts also said that they expected that heavy snow would develop on Wednesday from the central plains to the large lakes, which at times could see snowfall speeds of approx. 1 inch per hour. At least 5 inches of snow would probably accumulate in these areas, according to the weather service, while a combination of gossip and freezing rain was probably over eastern Oklahoma and Ozarks. Although less than an inch was expected to dust the affected places further south, the weather service noted that “any amount of freezing rain could do for dangerous trips on untreated surfaces.”
