This storm system will introduce enough cold air to create snow and strong winds. The blizzard is expected to continue to sweep through the northern Midwest on Friday.
CNN meteorologist Dave Hennen said: “Most areas of the Midwest are under some sort of winter warning because the first heavy snow of the season is expected.”
The total snow cover is only 2 to 6 inches. But wind speeds will be as high as 60 miles per hour, causing snowy weather in parts of the plains.
The blizzard warning will continue until noon on Friday, covering most of the northeastern part of South Dakota.
“Travel should be limited to emergencies,” the National Weather Service said.
The Weather Forecast Center (WPC) said: “A huge and vibrant low-pressure system has brought snow and strong winds to the northern plains and the upper Midwest. It will steadily weaken today as it crosses the Great Lakes and then retreats to Canada tonight. .”.
You may think that it is too early to talk about snow in this season, but if you are in the upper Midwest, even if not a few days in advance, it is very punctual. Take Minneapolis/St. Louis as an example. In Sao Paulo, the first snowfall of 1 inch or more occurred around November 16. According to the office of the National Meteorological Administration of the Twin Cities, the area may experience “multiple snowfalls” this Friday, which “may be violent at times.”
“On Friday and overnight, light snow will enter parts of the Ohio River Valley and the Great Lakes because the snow cover on the upper Mississippi River is gradually decreasing.”
Hennen said another storm this weekend “will descend south from Canada and will bring large snowfalls to the larger Midwestern cities such as Chicago, Milwaukee, Detroit and Cleveland.”
Heavy rain over the weekend threatens to move northeast
After the storm gave many people a first taste of winter in the upper Midwest, it will continue to expand and move slowly eastward. The first half of the depression will attract precipitation and mild temperatures northward, threatening localized heavy rain from the Ohio Valley to New England.
“As the system moves eastward, moisture from the Atlantic Ocean will flow into parts of the Northeast on Friday. Sometimes heavy rain will enter the Northeast/Central Atlantic and Carolina,” WPC said.
This is why they published the marginal risk of excessive rainfall in parts of the Northeast from Friday to Saturday morning.
The total amount of rainfall throughout the weekend will be between 1 and 2 inches. Nevertheless, the local accumulation in southern New England may reach 2 to 4 inches.
Rain will pass through major cities from late in the morning to early in the afternoon.
Some of the rainfall may drop within a few hours, increasing the risk of flash floods.
“The related heavy rain will cause flash floods in local areas, affecting areas that experience heavy rain and rapid runoff,” WPC said.
By the weekend, the temperature behind the storm system in many East Coast cities will drop by 15 to 25 degrees, enough to remind us that winter is approaching.
