The fall clash of seasons will be evident across the U.S. this week as a mix of severe storms, wintry weather and wild temperature swings make for active weather for millions of Americans.

Widespread precipitation and heavy mountain snow are expected in the northwest and northern Rockies on Monday, the National Weather Service said. The higher elevations of the Cascades and northern Rockies could see up to a foot of snow, wreaking havoc on motorists venturing out.

And in the central U.S., thunderstorms forming along a cold front could bring damaging winds and perhaps a few tornadoes between central Oklahoma and north Texas Monday afternoon and evening.

Meanwhile, elsewhere, some of the season’s coldest air is poised to spread across much of the central, southern and eastern US later this week: ‘This colder air should arrive in the Plains around Wednesday and then have to flow quickly over the rest. of the South, Lower Midwest and East Thursday,” Weather.com meteorologist Jonathan Erdman said in an online report. “It will likely continue through the weekend,” he added.

For much of the Northwest, the northern Great Basin and the northern Rockies, a cold front moving across the region on Monday will bring unsettled weather ahead of another powerful storm system expected to develop off the Northwest coast on Tuesday will develop, the weather service reports. said.

“This taste of precipitation to start the work week will mainly include the possibility of moderate to heavy snow in the Cascades and northern Rockies,” weather service meteorologist Cody Snell said in an online forecast.

The weather service warned that due to the snow, roads and especially bridges and overpasses are likely to become slippery and dangerous throughout Monday and Tuesday: “Expect slippery roads. If you must travel, make sure you have an extra flashlight, food and water with you has in hand.” in your car in case of emergency.”

In California, forecasters warned of a hard freeze Monday evening across much of the central valley: “Frost and freezing conditions could kill crops and other sensitive vegetation and potentially damage unprotected outdoor pipes,” the weather service in Sacramento said.

Tornadoes and heavy rain possible in central US

The threat for a few tornadoes and damaging winds will exist Monday afternoon and evening from parts of East Texas to Louisiana and the surrounding area, the Storm Prediction Center said.

A tornado watch will likely be issued later Monday for parts of Texas and Louisiana, meaning conditions will be ripe for tornado formation.

In addition to the tornado threat, heavy rain will most likely occur in eastern Louisiana and southern Mississippi on Monday evening, and the threat will expand eastward into the Florida Panhandle on Tuesday, the weather service said.

Winter is approaching; the hurricane season is nearing its end

A major storm is brewing around the Great Lakes this week that will not only bring wintry changes to much of the eastern U.S. but could also bring much-needed rain, AccuWeather meteorologists say.

How cold will it be later in the week? Erdman said low temperatures in the 30s and 40s will be common in the South, and even Florida could have chilly mornings in the 40s and 50s. Meanwhile, highs in the 40s and low 30s will be the rule in the Midwest and the Interior Northeast, he said.

With the cold air flow comes good news from the tropics: ‘One thing the big Midwest storm and the spread of colder air south and east later this week will do is effectively end the risk of tropical storms making landfall come. in the U.S.,” said Brett Anderson, senior meteorologist at AccuWeather. “There may still be some tropical activity over part of the Atlantic basin, but that will likely be deep in the tropics or over the central Atlantic and not near the US”
