Dangerous wind chill values will be digging through the Midwest again tonight. Wind chill readings as low as -50 will be hitting Minnesota, North Dakota and Iowa the hardest this evening and into the morning hours tomorrow.
A strong area of high pressure will move into the upper Midwest through the day today increasing to 1044mb. An area of low pressure is sitting over New England and the pressure gradient between these two areas of pressure will create very strong winds.
The image above depicts the sustained winds tomorrow morning at 6:00 a.m. CST. Winds will be blowing over 25-30 mph for much of the area, especially across Iowa, Minnesota and Illinois.
Combined with the cold air in place over the Midwest, these winds will create very dangerous wind chills, therefore Wind Chill Warnings and Advisories are up for a huge chunk of the Midwest all the way down to Oklahoma.
There will be a little area of snow moving through the upper Midwest tonight, combined with these strong winds, this will create blizzard conditions. Therefore the NWS has issued Blizzard Warnings for parts of South Dakota and Minnesota. No large accumulations are expected.
