Snow and thunderstorms could spoil holiday travel this week | Tech US News



As millions of Americans prepare to travel during the Thanksgiving holiday week, many will have to contend with rain, snow, high winds and cold temperatures.

More than 5 million people from Michigan to New York are under winter weather warnings as additional lake effect snow is expected to fall on Sunday.

Meanwhile, rain and thunderstorms will be the main concern in some southern states.

More than 2 feet of snow fell in parts of Wisconsin, Michigan and Minnesota in recent days, and a hit of more than 6 feet of snow fell in New York state. With temperatures barely above the low 40s for the next few days, a lot of that snow will stick around.

Cold temperatures after the snow ends can also be dangerous.

“The day you have fast-falling snow, you’re almost blinded by the visibility as you drive,” Jonathan Guseman, warning coordination meteorologist for the National Weather Service in State College, Pennsylvania, tells CNN. “The snow melts on the road and then the cold air surge behind the snowstorm freezes that melted snow and produces what we call a flash freeze, where it’s almost impossible to maintain traction and drive safely on the road.”

This week more than 70% of the US population (more than 230 million people) will see temperatures at or below freezing.

Sunday will begin with virtually everyone east of the Mississippi River and most of Texas feeling more like January than November with temperatures 10 to 20 degrees below normal.

It is predicted that St. Louis will have a high on Sunday of just 40 degrees, its normal high for January of 10 degrees.

Cincinnati is forecast to have a high temperature of just 32 degrees Sunday, 20 degrees cooler than its normal high temperature of 52 degrees.

Even a southern city like San Antonio isn’t much better. Its forecast to have high temperatures on Sunday of only 49 degrees; its normal maximum temperature is 70 degrees.

A series of storms will push into the Pacific Northwest bringing rain to the coast and valleys, and snow to the Olympic and Cascade mountains this week.

“A weak weather system moves through the area late Sunday night or Monday morning, followed by a stronger one on Tuesday,” the National Weather Service office in Portland said.

The northern Rockies will also see precipitation chances Tuesday through Wednesday as the frontal system moves through.

Rain accumulation is not expected to be very high, with most areas accumulating less than 1 inch through Wednesday.

The southern United States, however, will see slightly higher rainfall amounts this week.

A low pressure system in the Gulf of Mexico is bringing rain across Texas on Sunday, reaching Louisiana on Monday and Alabama and Georgia on Tuesday.

However, areas of Florida have a chance of rain every day Sunday through Wednesday, including Orlando, Miami and Key West.

Overall, rain accumulations in Texas and Louisiana will remain between 1 and 2 inches, but slightly higher along Florida’s east coast, which could increase to 3 inches by midweek.

The Weather Prediction Center (WPC) warns that isolated flash flooding may be a concern in all urban areas.

The biggest weather concern this holiday week looks set to take place starting Thursday in the middle of the country.

For now, the Macy’s Thanksgiving Day parade in New York should be able to play without the rain, but on Friday, you might need that umbrella in the Northeast for some Black Friday shopping.

“A few low pressure systems, including a possible Nor’easter, could bring significant rainfall to parts of the eastern United States late next week,” the WPC said this weekend.

This could bring rain/snow and unpleasant travel conditions to many major cities east of the Mississippi River through Saturday.

“Current forecasts indicate that wintry precipitation is a better chance for the inland Northeast while metro areas along the I-95 corridor are more likely to see rain,” the WPC said.

But keep an eye on future forecasts this week as details like snow versus rain could change in the coming days.
