AccuWeather Global Weather Center - As an area of low pressure moves through northern Minnesota and northern Wisconsin on Wednesday, many residents of the north-central United States will have a breezy but mild day. However, north of the track of the low pressure, rain is likely to mix with snow. This is most likely to occur in the morning, when temperatures will be at their lowest. Any snow will largely by confined to northeastern Montana and northwestern North Dakota, and precipitation will end by late morning as the low pressure continues to move eastward.
Even where snow does not fall, winds will make for a chilly day. Billings, Montana; Bismarck, North Dakota; Rapid City, South Dakota; and Cheyenne, Wyoming, are just a few locations that are likely to experience strong winds on Wednesday.
In the wake of the low pressure, a southward dip in the jet stream will allow for the areal extent of the cold air to expand on Wednesday night and Thursday. For example, after a forecast high of 65 degrees Fahrenheit on Wednesday, Minneapolis will struggle to make it out of the 40s F on Thursday, which is well below normal.
Cold and Possible Snow
"High temperatures in the upper 50s to lower 60s are typical across a wind swath of the North Central states from the Dakotas east into Michigan," said AccuWeather Meteorologist Mary Gilbert.
In addition, while not quite as strong as Wednesday, windy conditions are likely to continue, leading to some very cold AccuWeather RealFeel™ Temperatures.
"Ultimately, for those who venture outside across the north-central U.S., this will lead to temperatures feeling 15-20 degrees colder than normal for the middle of October," Gilbert stated.
Chilly but tranquil weather is in store for Friday, although there will still be a bit of a breeze.
