- It will feel “incredibly warm for January,” in places like Illinois, Indiana and Ohio.
- Widespread severe thunderstorms are likely late this week in parts of the South.
- Some of the heaviest snow is likely in portions of Wisconsin and Michigan.
A wild potpourri of weather is in the forecast by the end of the week over the eastern half of the nation, forecasters say.
Following a mid-week chill, record-challenging warmth will bring a mid-winter “heat wave” across the eastern U.S. by the end of the week. At the same time, the South will be bracing for both a severe weather outbreak and a flood threat while a snowstorm targets the central U.S. and portions of New England.
By Friday, temperatures will soar into the 50s and 60s as far north as Illinois, Indiana, Ohio and southern Michigan, AccuWeather said, locations where frigid temperatures usually rule this time of year.
It will feel “incredibly warm for January,” AccuWeather senior meteorologist Eric Leister said.
By Saturday, the warmth will spread into the East Coast, where temperatures could hit the 70s in Washington, D.C., and the 60s in both New York City and Boston.
While the Midwest and East sees the warmth, widespread severe thunderstorms – including tornadoes – and flooding rain are all likely late this week in parts of the South, despite it being the first full week of January, the Weather Channel warned.
Calling it a “volatile weather pattern,” NOAA’s Storm Prediction Center said that “a multi-day severe weather episode is expected across portions of the Arklatex into the Deep South” Friday and Saturday.
Severe weather, including tornadoes, wind and hail, could pound parts of Texas, Arkansas and Louisiana on Friday and much of Mississippi and Alabama on Saturday.
The threat zone will include major metro areas such as Dallas, Houston and New Orleans, AccuWeather said.
The storm will also deliver heavy rain that could lead to flash floods and river floods from the Ohio Valley to the Lower Mississippi Valley, the National Weather Service said.
“The greatest risk for significant rainfall and potential flooding exists from east Texas and Arkansas into the central Mississippi Valley, eventually encompassing parts of Illinois, Indiana, and the Ohio Valley before perhaps impacting the Northeast into Sunday,” the Capital Weather Gang’s Matthew Cappucci said.
A band of significant snow and ice is also forecast from for a 1,700-mile stretch from the Central Plains into parts of the Midwest, Great Lakes and northern New England later this week and into the weekend, the Weather Channel said.
Some of the heaviest snow is likely in portions of Wisconsin and Michigan, where up to a foot is possible, according to the Weather Channel.
AccuWeather predicts that Chicago and Detroit may face the threat for a wintry mixture of precipitation beginning Friday night.
