As winter begins to take hold, the chill makes its way across the United States from coast to coast

Despite the fact that the calendar indicates we’re only in mid-November, cold is making its way into the lower 48 states of the United States and could last until Thanksgiving Day.

Snowfall and arctic cold are in the picture for millions of people across the country this week. A low pressure system in the southwest will affect the central plains on Monday, causing rain and snow.

According to the Weather Prediction Center, it will be the first major event of the winter season in most areas.

“While uncertainty remains regarding the location of the heaviest snow axis, the potential for snow totals from 76 mm to 152 mm exists in west-central Oklahoma,” the forecast center said. “Light snow is also possible across southern Kansas and northwest Texas.”

Winter weather advisories are in effect for the entire region, including Kansas City, Oklahoma City, Wichita in Kansas, Amarillo in Texas and Fort Smith in Arkansas. Snow will reduce visibility and dangerous driving conditions on Monday.

The system will move east this week and temperatures will remain well below normal. Snow showers, sleet and sleet are possible across the Midwest and Inland Northeast on Tuesday and Wednesday.

Cool rain is likely over the Mid-Atlantic and Northeast Coastal regions as temperatures are expected to remain just above freezing.

If you haven’t already, you might want to find your winter coats and sweaters. More than 225 million people in the lower 48 states will experience freezing temperatures this week, which is equivalent to 70% of the US population.

Colder temperatures have already reached 5.5 to 11 °C below normal for many, with temperatures below freezing in the northern Plains and upper Midwest, and 10 °C in the South.

The Central Plains recorded the coldest temperature compared to the average, with a minimum temperature of 13 to 16 degrees Celsius below normal on Monday.

Only Florida escapes the early winter chill, but the sunshine state will also be hit by a cold wind this weekend.

By Thursday, another gust of arctic air will move south from Montana to the Central Plains and into the Midwest by Friday, pushing colder temperatures 50 to 65°F below normal.

If the cool breeze helps get you in the Christmas spirit, you’re in luck! This arctic air is expected to linger over much of the country through Thanksgiving week. Next week’s arctic air bullseye will extend into the Great Lakes south of the Tennessee River Valley.

We’ll have more details on how cold Thanksgiving week could be and how to prepare for travel risks in next Monday’s weather report.

In the meantime, now that the cold, chilly weather has set in, we want to share some of the weather terms you’ve probably been hearing a lot about this season. And they can help you impress your friends with your meteorological knowledge.

polar cyclone

It’s not a new term, but the polar vortex is always around and always has been.

It is a large area of ​​low pressure and cold air that surrounds the Earth’s north and south poles and extends tens of thousands of meters into the atmosphere. This counter-clockwise flow helps to keep very cold air near the poles.

The National Weather Service explained, “At times during the Northern Hemisphere winter, the polar vortex will expand, sending cold air southward along the jet stream.” “It occurs fairly regularly during the winter and is often associated with large outbreaks of arctic air in the United States.”

The month of February 2021 was a classic example of the weakening of the polar vortex, which sent arctic air far to the south. In one week in February, every state in the United States experienced freezing temperatures.

Sometimes cold air settles down and meets warm, moist air moving north from the Gulf and Atlantic, resulting in a ‘nor’easter.

nor easter

If you’re one of our Northeast friends, you’re no stranger to ‘nor’easters, which are storms that travel north along the East Coast. Its name comes from the fact that the winds in the coastal areas generally blow from the northeast.

“They almost always bring precipitation in the form of heavy rain or snow as well as hurricane force winds, rough seas and sometimes coastal flooding in affected areas,” the weather service said. “The ‘I-95 Corridor,’ a densely populated area between Washington City, Philadelphia, New York and Boston, is particularly affected by Nor’easters.”

‘Nor’easters’ can bring this region of the country to a standstill, disrupting traffic, stopping flights and sometimes causing power outages.

If the ‘nor’easter’ intensifies rapidly, we may drop a cyclonic bomb.

A bomb cyclone is a rapidly strengthening storm that drops 24 millibars (a unit of pressure) in 24 hours. it’s that easy. It doesn’t explode anything, but it can be dangerous.

We have seen cyclonic bombs with hurricane-like fury both on the northeast and west coasts.

Last year, this West Coast bomb cyclone brought hurricane-force winds, 20-foot tides, rain and snow to much of the West.

Winter weather is interesting no matter how you classify it. But if Mother Nature throws a punch during the winter, you might be lucky enough to hear a thunderous snowfall!

snow with thunder

Although winter thunderstorms are much less common than in summer, they can occur.

The National Oceanic and Atmospheric Administration (NOAA) says, “Thunderstorms occur when there is relatively strong instability and abundant moisture above Earth’s surface, such as above a warm front.” “The ingredients that make up snowstorms are similar in dynamics to a typical thunderstorm: moisture, instability, and a lifting mechanism.”

We’ve heard snowstorms with thunder many times, covering large snow events, and it’s different from summer thunder. Heavy snow can drown out the sound of thunder, making it sound more like a low rumble and not as thunder.

And of course, snow accompanied by thunder is a sign that lightning is nearby, so treat it like a thunderstorm and take cover.
