Two major storms hit the United States this weekend

Dual storm systems are spreading across the country this weekend, bringing high-impact weather from California to the northern tip of Maine. Few places will be spared from severe weather, with spring storms, flooding and tornadoes for some, and the possibility of blizzard conditions for others.

A storm system was drenching the Mid-Atlantic and Northeast on Saturday, and was poised to hit northern New England with heavy snow. The rain was expected to end by noon in the nation’s capital, but could last into the afternoon in New York and Boston.

Meanwhile, winter storm warnings were in effect for much of upstate New York, Vermont, New Hampshire and Maine. Those are the places where a messy mix of snow, sleet and ice was anticipated. For regions where there is primarily snow, totals could approach two feet.

That winter storm was mirrored by a second one that originated in the West and is poised to consolidate east of the Rocky Mountains before moving across the northern Plains and upper Midwest. Winter storm watches and warnings extend from the Sierra Nevada and northern Rocky Mountains to northern Wisconsin, with a swath of blizzard warnings hoisted for Lake and Cook counties in Minnesota. That includes the Grand Portage Reservation Tribal Lands, where 14 to 19 inches of snow is expected to combine with strong winds between Sunday and Tuesday night.

“Travel should be limited to emergencies only,” the National Weather Service wrote. “If you must travel, carry a winter survival kit. If you get stranded, stay with your vehicle.”

Minneapolis, which is under a winter storm warningThe system is expected to hit hard, with 6 to 12 inches of snow projected. Snowfall rates could reach one to two inches per hour during the peak of the storm between Sunday afternoon and evening. It comes amid what has been the second-least snowy winter on record in Minneapolis. They have only fallen 17.4 inches so far this season, compared to an average of 51.1 inches. The lack of snow is not surprising considering it has been the warmest time in Minneapolis. snow season to date on average; Since October 1, the city has been 7.1 degrees above normal. The Great Lakes have been largely ice-free due to similar smoothness further east.

That same storm system is expected to hit a band of severe storms across Oklahoma and Kansas on Sunday, which may contain hail, damaging winds and tornadoes. Behind the storms, a bone-dry air mass from the desert southwest is forecast to spread across the southern plains, combining with strong winds to raise critical fire concerns.

The active weather pattern appears to persist through the middle of next week before a calmer ridge of high pressure is expected to form over the central states.

On Saturday morning, a developing coastal storm was centered just northeast of Raleigh, North Carolina. The low pressure center is expected to work offshore, pushing a mass of moisture northward ahead. It’s primarily a rain storm for the Acela corridor, but central New England may see a mix of rain and snow. In the extreme northern areas, it will be all snow.

Rainfall totals have been a little lower compared to some initial model simulations through Saturday morning. Still, Dare County in eastern North Carolina recorded 2.55 inches and the north side of Richmond was approaching 2 inches.

DC had just eclipsed an inch, and New York’s Central Park was at 0.56 inches at 10 a.m. Washington could see totals reach 1.5 inches before the rains conclude shortly before lunchtime. New York City will likely end up with similar totals before the rain ends in the late afternoon.

The rapid movement of the storm, as well as the presence of offshore thunderstorms to “steal” or usurp moisture, is expected to limit the risk of widespread flooding. Even so, there is a flood alert due to possible stagnation of water on roads in urban areas.

In the interior of northern New England, heavy snow is forecast, while towards the coast of Maine it will be more of a mix of rain and snow. Southern Vermont and New Hampshire are also likely to experience a wintry mix. The precipitation will likely end there around midnight and move out of northern Maine around dawn Sunday.

While Portland, Maine, is expected to see between 3 and 6 inches of snow, totals will quickly increase inland. The northern halves of Vermont and New Hampshire could receive 8 to 14 inches, and in Maine’s northern Somerset, Piscataquis and Aroostook counties, a total of 18 to 24 inches is likely.

Winds are expected to increase in the rear of the system, with widespread winds of 25 to 35 mph and gusts up to 45 mph in eastern Pennsylvania, New Jersey, and along the southern New England coast. Otherwise, a cool breeze is expected to bring cold temperatures Saturday night into Sunday.

An expanding storm system is expected to hit the Plains over the next 48 hours. On the cold side, moisture engulfing the north will fall into frigid air, bringing heavy snowfall to northern regions accompanied by strong winds. To the south, a trailing cold front will bring severe storms to the southern plains, with weather ripe for fast-spreading fires to hit western Texas and Oklahoma, including the Panhandles.

An elevation disturbance is expected to spread snow into eastern Montana and the Dakotas overnight and into Sunday morning. It will increase in coverage and intensity as a surface low to the south strengthens, which in turn will draw more moisture northward and allow moderate snow to spread into central and northern Minnesota and northern Wisconsin. In Minneapolis, most of the snow is expected to fall on Sunday before it will likely mix with rain and turn into Monday.

As for accumulations, a wide swath of 10 to 18 inches is likely to form from northern South Dakota and southern North Dakota east to central and northern Minnesota and northern Wisconsin.

The same storm system is causing a dry line (the leading edge of completely dry desert air) and an eventual cold front, across Oklahoma and Kansas. This is expected to present a severe storm risk area from western and central Oklahoma west of Interstate 35 to western and central Kansas, primarily near and west of Wichita, on Sunday.

While wind shear, or a change in wind speed and/or direction, will be strong and could support rotating storms, the coming moisture The length of the dry line is expected to be limited. This could result in a reduced potential for severe weather, limiting what would otherwise have been an environment conducive to highly destructive storms.

However, some rotating supercells could form during the afternoon, producing a brief tornado and a high risk of hail before transitioning to windy squall lines and heading east.

Behind the dry line, strong winds, gusting between 40 and 65 mph at times, are expected to spread over eastern New Mexico, western Texas, western Oklahoma and southwestern Kansas on Sunday. When combined with very low relative humidities, the landscape would be a tinderbox. The Weather Service’s Storm Prediction Center is already warning of a critical wildfire risk in that area.

TO fire weather watch is in effect Sunday for much of this region.
