If the phenomenon repeats itself, for the second time this week, a sprawling winter storm tracking the central and eastern United States carries three threats, including stormy conditions in the Midwest, severe weather in the South and flash flooding in the East. .
Just a few days ago, a deadly winter storm struck the central United States and brought nearly a foot of snow and whiteout conditions from the Plains to the Great Lakes, where deadly severe storms and tornadoes swept across the South, while high winds and torrential rains led to power outages. to hundreds of thousands of Americans on the East Coast and caused rivers to rise to historic levels.
Weather alerts of all types have been issued in nearly every state in the Lower 48. Most are associated with winter weather, covering about 60 million people across the United States.
The active January pattern will continue into next week, even as the latest winter storm continues its journey across the country. Here are the latest impacts and timing for the wintry weather system tracked by the FOX Forecast Center through the end of the week.
A major winter storm hits Chicago and other Midwest cities
A major winter storm has swept through the Midwest, hitting major cities like Chicago and Milwaukee with heavy snow and high winds.
A blizzard warning already covers parts of several Midwestern states, including Iowa. This is where ground blizzards — falling snow blown by strong winds — will become a problem. If blizzard warnings are issued for Chicago, it will be the first time this has happened in about five years (November 26, 2018). The city of Milwaukee has not been under a blizzard warning in nearly 13 years (February 1, 2011).
The storm has already disrupted travel at Chicago's O'Hare International Airport, where it was grounded early Friday. Hundreds of flights were canceled or delayed at Chicago-O'Hare and Midway airports.

Heavy rain and stormy winds heading east
Most of Friday should be relatively calm along the East Coast, but heavy rain is expected to fall over the Mid-Atlantic and Northeast on Friday evening. Most of the area will pick up an inch or two of rain Saturday afternoon.
With the ground already saturated after heavy rains earlier this week, flash flooding could become a concern from Friday night into early Saturday before rain falls off the coast later Saturday.
New York City, Philadelphia and Boston were all highlighted for Level 2 of 4 flash flood risk by the National Oceanic and Atmospheric Administration's (NOAA) Weather Prediction Center.
The rain will also be accompanied by gusty winds, but winds are not expected to be as strong as Tuesday's storm when some areas reported wind gusts of more than 70 mph.
