Entire continental US could be hit with extreme weather this weekend — including blizzards, tornadoes and flooding

In a case of déjà vu, for the second time this week, a sprawling winter storm tracking across the central and eastern U.S. is packing a trio of threats, including blizzard conditions in the Midwest, severe weather in the South and flash flooding in the East. Just a few days ago, a deadly winter storm slammed the central U.S.

and brought nearly a foot of snow and whiteout conditions from the Plains to the Great Lakes as deadly severe storms and tornadoes raked the South, while high winds and flooding rain knocked out power to hundreds of thousands of Americans on the East Coast and sent rivers rising to historic levels. Weather alerts of all types cover every state in the Lower 48.

The majority of them are related to winter weather, covering nearly 60 million people across the U.S. An active January pattern will continue into next week, even as the latest winter storm continues its trek across the nation. Here are the latest impacts and timing for the winter weather system the FOX Forecast Center is tracking into the weekend.

A major winter storm has charged into the Midwest and is blasting major cities such as Chicago and Milwaukee with heavy snow and high winds. A Blizzard Warning already covers parts of several Midwest states, including Iowa. That is where a ground blizzard – fallen snow being blown around by high winds – will be a problem Friday.

If Blizzard Warnings are issued for the city of Chicago, it would be the first time that has happened in about five years (Nov. 26, 2018). The city of Milwaukee has not been under a Blizzard Warning in nearly 13 years (Feb. 1, 2011). The storm has already snarled travel at Chicago’s O’Hare International Airport, where a ground stop was issued early Friday.

Hundreds of flights have been canceled and, according to the Federal Aviation Administration, delays are averaging about 2 hours. Snowfall totals between 5 and 8 inches are forecast for cities like Chicago and Des Moines, Iowa. Even higher amounts are expected to the north across Wisconsin, where Milwaukee and Green Bay could pick up a foot or more of snow.

Severe thunderstorms are tracking across the South through Friday, packing threats of damaging wind, large hail and tornadoes. States with the highest risk of dangerous storms include Mississippi and Alabama, but that threat shifts east during the day to include Florida, Georgia and the Carolinas. Damaging winds and some tornadoes are the main threats through Friday evening before the storms push offshore into the Atlantic.

Much of Friday should be relatively quiet along the East Coast, but a slug of heavy rain is forecast to push into the mid Atlantic and Northeast on Friday evening. Much of the region will pick up an inch or two of rainfall by Saturday afternoon. Given the ground is already saturated after the heavy rainfall earlier this week, flash flooding could become a concern from Friday night into early Saturday before the rain exits off the coast later Saturday.

New York City, Philadelphia and Boston have all been highlighted for a Level 2 out of 4 risk of flash flooding by NOAA’s Weather Prediction Center. Gusty winds will also accompany the rain, but the gusts are not expected to be as strong as those from Tuesday’s storm when some areas reported gusts over 70 mph..
