Early-Week Storm Bringing Blizzard Conditions, Thunderstorms and Big Temperature Changes to Central U.S.
Published: December 4, 2017
A potent low-pressure system is tracking eastward to begin this week, spreading rain, thunderstorms, snow and strong winds through the central and eastern states. Blizzard conditions are accompanying this storm in parts of the northern Plains.
In addition to the chance for precipitation, a big temperature change will be ushered in behind the cold front associated with this system.
This weather system brought snow to the Mountain West over the weekend and is now tracking through the central states. The low-pressure system will continue to slide eastward and is expected to push off the East Coast midweek.
Current Radar, Winds and Temperatures
Blizzard warnings are posted for parts of the eastern Dakotas and northwest Minnesota, where snow and wind gusts up to 55 mph will create dangerous travel conditions into Monday evening. Various winter weather advisories and winter storm warnings are also in effect from the northern Plains to northern Minnesota.
Current Winter Watches, Warnings and Advisories
Whiteout conditions were observed in Sioux Falls, South Dakota, Monday evening as heavy snow combined with wind gusts up to 60 mph.
Snow and wind from this weather system prompted a closure of Interstate 80 in southeast Wyoming Monday morning, from Rawlins to Laramie.
Stretches of interstates 29, 90 and 94 in the northern Plains will also be affected by snow and wind through Monday evening.

- The cold front will likely push off the East Coast, with the possible exception of southern Florida.
- The risk of rain will once again stretch along parts of the Eastern Seaboard (early in the day) south to the Gulf Coast, possibly as far west as southern Texas.
