Tornadoes, blizzards and huge waves: Almost the entire United States will experience severe weather

The situations are not that unusual to happen Somewhere heavy weather of the 48 states of the continental United States, especially in January. As the frigid air of the Arctic collides with the mild air of the mid-latitudes, severe storms are common. But it’s pretty unusual for almost every state to see wild weather in a single week, and it’s going to happen.

An exceptionally active weather pattern will cause Multiple major storm systems that will cross the entire country. Air masses will battle, causing possible tornadoes and blizzards. Monster waves will hit the coast of California, until then meters of snow and hurricane winds They will cover the peaks of the Sierra Nevada. In the east, after cold and snow this weekend, heat and heavy rain could spread north next week.

Meteorological chaos, fueled by strong weather patterns of boy, Just over a week will result in a possible outbreak of cold air that could drop temperatures across much of North America.

Here are seven weather extremes to watch out for:

The first is the storm which will extend from the Mid-Atlantic to eastern New England later this week. Cold air will envelop you, dumping moderate to heavy snow inland while cold rain drenches the coast. Some snow may form in western parts of Virginia and North Carolina.

A total of up to 8 inches of snow is possible from Pennsylvania to the southern Hudson Valley, with an additional band of snow possible off the immediate south coast, into New England. Local totals can reach double digits, especially in the corridor from Boston to Manchester, NH and west to Albany, NY.

“Uncertainty remains in the system’s track and intensity,” wrote the National Weather Service forecast office serving Boston. “This will influence specific (snow) totals, (rainfall) types and impacts over our region.”

near the shore, around 3 cm of rain. Meanwhile, the Interstate 95 corridor is near the rain-snow line, but minimal snow accumulation is forecast in New York City, Philadelphia, Baltimore and Washington.

Saturday’s storm May bring snow in the DC area for a short time before turning to rain

A rapidly moving storm will move through Saturday morning and Sunday afternoon before moving out.

It’s been just over a week since massive waves hit California’s coastal communities and dumped seawater, injuring many. Sea waves with heights of up to 10 meters prompted high surf warnings, with some breakers exceeding 12 meters. Now a new wave of big waves is about to hit the coast.

Some call them “sneaker gloves”, A loosely defined term to describe surprise waves twice as high as surrounding waves. Although there is high confidence that coastal flooding in the Saturday-Monday period will not be as severe as last week’s episode, the Weather Service office serving Southwest California is urging residents to swim only near lifeguards and stay away from rocky jetties.

Maximum wave heights of up to 5 meters are expected along California’s central coast, and up to 2.5 along Los Angeles beaches.

On Sunday, European model projects 9 to 15 m offshore waves, Courtesy of a storm system moving down the Pacific coast and rolling out to sea.

The same system will direct a narrow filament of moisture from the Pacific toward California. Part of that moisture will concentrate in the mountains, producing half a meter of snow at elevations above 2,000 meters. Over the highest mountain peaks, heavy snowfall combined with winds of 80 to 160 kmph will cause heavy snow conditions. The worst comes between Saturday and Sunday morning.

Winter storm watches extend from the Oregon Cascades to the Sierra Nevada northeast of Bakersfield, California. Visibility may drop below 800 feet in the high Sierra between Madera and Tulare.

Snow in the Sierras, though harmful to travelers, will be Beneficial for water supply, So far this season the proportion is only between 30 and 40 percent of normal.

He will make it New storm system Somewhere in the South Mississippi Valley around Tuesday of next week. Because it is excited by high-altitude disturbances (pockets of cold air, low pressure, and spin in the air), it will intensify rapidly. That surface strength should spread across the Tennessee Valley and into the Midwest and Great Lakes by Wednesday.

To the west, moisture accumulating on its cold side will leave a band of snow, which could affect Kansas City, Missouri; St. Louis; Springfield, Illinois; and Indianapolis. Chicago and Detroit may end up on the edge of the heaviest snowfall area, so potential amounts are uncertain.

“The current advice is to continue to monitor for updates and is Winter preparation plan In case of a change in cold solution,” the weather service office in Indianapolis warned.

There will also be a cold air stream in the back of the storm that will bring stronger winds. 56 km/hr. Those winds will combine with falling snow to potentially reduce visibility for extended periods. That will lead to blizzard conditions and the possibility of some power outages, especially in the eastern Great Lakes.

On the hot side of the same system, Severe storm Because moist air moves north from the Gulf of Mexico. Those storms tend to develop vertically in the air mass, which is characterized by wind pressure, or changes in direction with wind speed and/or height. It can cause some of them to spin, creating a tornado.

There is also a lot of jet stream energy overhead, so storms will likely mix some momentum with the ground in the form of straight-line wind gusts.

He Weather Service Storm Prediction Center A watch has already drawn up from Houston to Mobile, Alabama on Monday, and the threat will expand to southeast and north of Florida on Tuesday.

“Supercells and short line segments capable of producing tornadoes, large hail and damaging winds are expected to be at risk,” the agency warned.

While producing snow in the Midwest and triggering severe storms in the South, this same storm will send a surge of warm air and moisture up the East Coast, creating the potential for widespread heavy rain.

A large footprint is expected heavy rain, from the coasts of Texas and Florida to the border between Maine and Canada. In the Northeast, rain will follow weekend snow and flooding in December. A combination of heavy rain and melting snow can cause river flooding.

Meteorologist Ryan Mau An estimated 61 trillion gallons of water will fall in the lower 48 states next week, an amount “enormous even for summer.”

A storm that struck the Northeast a week before Christmas may have similar characteristics, which just didn’t produce. Major river flooding But coastal flooding and strong winds knocked out power to more than 800,000 customers.

Computer models indicate the possibility of a large cold front in the western and central United States in about eight to 10 days.

It appears that a large reduction in the jet stream will allow bitter arctic air to move southward, causing The temperature drops below normal. Models still don’t agree on the magnitude of this potential cold air surge, nor how far east the cold will extend.

As colder weather moves into more of the lower 48 states, the chance for mid-month snow will increase in the Southern Tier, which has yet to experience much winter weather this season.
