Шаблон:Short description Шаблон:Infobox winter storm The February 2022 North American winter storm was a widespread, damaging, and severe winter storm which affected a wide swath of much of the United States with widespread wintry precipitation; it spread from Texas northeast to Maine.Шаблон:Dead link Nineteen states in the U.S. were impacted by the system; more than 90 million people were in the storm's path. The winter storm was named Winter Storm Landon by The Weather Channel and was also referred to by other media outlets as the Groundhog Snowstorm, primarily due to the storm impacting on Groundhog Day.

The storm spread a widespread swath of heavy snowfall stretching from Texas to Maine, with anywhere from Шаблон:Convert falling. It also caused many disruptions as well, with over 375,000 people losing power as a result of the storm and many accidents occurring on snowy roadways as well. 7 deaths were attributed to the winter storm's impacts. Five tornadoes also occurred within the warm sector of the storm in Alabama on February 3; three of them were rated EF2.

Meteorological history

Over much of the Midwest, temperatures were unseasonably mild on February 1 as a strong cold front moved southward over the region. Rain began to fall in the early afternoon over the Central Midwest, and temperatures began to drop as the front draped southward. During the early evening, an upper-level low began to form along the front and interacted with a jet streak producing lift. As the temperatures on the backside of the front cooled and fell below freezing, the rain quickly turned to snow and thanks to the lift, made perfect conditions for lots of snow with rates receiving 1" an hour in some places. The winds also picked up to 30–35mph causing many cases of blowing and drifting snow. This snow continued through the night with areas along and south of I-70 in Missouri and Indiana receiving more of a wintry mix and rain.

During the night and morning of February 2, a second upper-level low began to form over Texas. Snow accumulations occurred in areas west of I-35 while areas east received freezing rain and sleet. This system also began to advance northeastward along the cold front. Meanwhile, the first system also continued northeast and by the late-morning moved out of the Western Midwest and by the afternoon moved out of the rest of the area and into the northeast. But during the night, the second system moved back over the same area as the first bringing yet another round of snow to many of the same regions while areas in Arkansas and along the Ohio River Valley received heavy freezing rain and sleet.

The energy from the two systems began to merge over the northeast during the morning on Thursday, February 3. By this time the system had become so large that precipitation associated with the system was falling over nearly half of all the US states, from Texas to Maine, but with the bulk of it still over Texas and Arkansas. During the late morning this would shift to over the Ohio River Valley while snow began to become heavier in the northeast and moisture being pulled northward by the system would cause a small severe weather outbreak over Alabama. The storm continued to move northeast and by that night was over mainly the Northeast. Snow would continue through the day on Friday, February 4 before the bulk of the storm moved offshore in the early afternoon. It would reach a minimum pressure of Шаблон:Convert around this time as well.Шаблон:Citation needed
