A mid-April storm has delivered a sharp reversal in the Sierra Nevada.

At Palisades Tahoe, 22 inches fell in 24 hours, pushing the three-day total to 43 inches (109 cm). Snow levels dropped to around 4,000 ft (1,200 m), bringing higher-quality snow to upper elevations.

A second core hit landed farther south.

Near Mammoth Lakes, more than 3.5 ft (1+ m) fell over the weekend, including 42.5 inches (108 cm) between Friday and Sunday. Blizzard conditions forced the closure of Interstate 80 through the Sierra.

The pattern shift is not isolated.

A strong cold front descends into the central and eastern United States this weekend, ending the current warmth and flipping temperatures back to well below average.

The driver is upstream. A deep trough tied to that persistent Hudson Bay ‘polar vortex’ — still unusually strong for mid-April — is releasing colder air south as the eastern ridge breaks.

A powerful tornado in Oklahoma on Thursday ripped roofs off buildings, knocked down power poles and sent emergency crews rushing into a rural community near Vance Air Force Base, officials said.

The confirmed tornado moved across parts of Enid, a city of about 50,000 people near the state's northern border, according to the National Weather Service.

Video posted online show a rapidly rotating column of air touching down along with totaled homes.

There were no immediate reports of fatalities and only minor injuries hours after the tornado passed through, according to the Garfield County Sheriff's Office.

Authorities were going door-to-door in some neighborhoods to check on residents.

The Vance Air Force Base was impacted by the tornado, but the extent of the damage was not immediately clear.

The base said in a social media post that officials "are currently conducting accountability procedures to ensure all personnel are safe and accounted for."

A sharp cold front is sweeping the United States, flipping the central, northern, and eventually eastern states from spring warmth to late-season freezes.

The Weather Prediction Center has stark lows spreading from the Southern Plains into the Midwest and Northeast through week’s end, as a very cold air mass drops in, returning the Rockies, Plains and Upper Midwest to snow, frost and freeze territory.

The likes of Wyoming have already taken a hit.

On Tuesday, Rawlins fell to 8F (-13.3C), breaking its May monthly low-temperature record of 10F (-12.2C), set on May 2, 2013, in books dating back to 1951. NWS Cheyenne also expects another daily record low there Wednesday, May 20.

Freeze Warnings cover parts of southeast Wyoming and western Nebraska. NWS Riverton warned of 25F to 30F (-3.9C to -1.1C) across parts of central Wyoming, with pockets near 20F (-6.7C) where snow remains on the ground.

The cold has already gripped north of the border.

Winnipeg Airport, for example, just endured one of its coldest May Long Weekends in records dating back to 1872. The weekend maximum reached only 10.6C (51.1F), tied with 1882 for the coldest on record. The average daily maximum was 9.3C (48.7F), second coldest. The three-day mean came in at 5.2C (41.4F), the coldest May Long Weekend since 1997.

Snowflakes were also reported, which, while not unheard of on the May Long Weekend, averages only about once per decade.

A cold air mass is driving south through the CONUS, dragging snow across the higher terrain and sending temperatures to record lows from Wyoming to Colorado.

Rawlins, WY, had already broken its all-time May low on May 19, with 8F (-13.3C) beating the old monthly mark of 10F (-12.2C) from 2013. The cold then held. On May 20, Rawlins fell again to 17F (-8.3C), breaking the daily record of 20F (-6.7C) set in 2001. Weather books there date back to 1959.

Colorado joined the list on May 21, when Grand Junction Regional Airport dropped to 32F (0C), beating the old daily record of 33F (0.6C) from 1974 (in books back to 1893).

Farther south, Oklahoma City tied its record cold high for May 20, reaching only 63F (17.2C), matching the mark set in 1942. Not a record minimum, but still a suppressed late-spring maximum deep in the Plains.

The wintry conditions also impacted Canada.

In northern Quebec, La Grande-Rivière Airport near Radisson picked up nearly 13 cm (5.1 inches) of new snow from May 20 to 21, lifting its monthly total to 34 cm (13.4 inches). Meteorologist Patrick Duplessis said that marks a new May snowfall record in data since 1977.

Queens alone reported a downfall of 2.57 inches.

One X user claims the floods hit within a "span of 25 minutes."

Winds reached 60-mph as commuters desperately tried to avoid being swept off their feet.

Queens Village native Charlton D'Souza said it was "some of the worst flooding" he had ever seen.
