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.

New Yorkers captured footage of a wild storm that almost drowned the city late Wednesday night.

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.

Tioga Road through Yosemite National Park was closed Tuesday, May 26, as a late-season storm moved into the Sierra Nevada.

The road had only just reopened for the season. Bicycles were allowed through on May 14. Vehicles followed on May 15. Less than two weeks later, snow was back and the high-country route was shut again.

Snow was forecast across the central and southern Sierra, with levels dropping to around 5,500 ft (1,670 m). Other high passes, including Sonora, Monitor and Ebbetts, also faced closures as the cold system pushed through.

Across the wider U.S., the pattern is turning sluggish. An Omega Block is expected to build after Wednesday’s rain, holding mild afternoons, cool nights and below-average readings in place.

Late May is not delivering a clean summer switch, particularly in the West.

Spring 2026 ran colder than normal across Alaska, particularly southern parts.

Illinois has led the nation in preliminary tornado reports for most of 2026, and after five were tallied during a severe weather outbreak on Wednesday, the state has surpassed its record for the most in a year. And it's only June.

There have been 164 tornado reports in Illinois as of June 18, according to data from NOAA's Storm Prediction Center (SPC). The large number is mostly due to tornado outbreaks in March, April and June. Illinois had only one tornado report in May.

Mississippi has the second-highest tornado count so far in 2026, with 82 tornadoes, exactly half of Illinois' total.

Late June is delivering another cold shot across large parts of the U.S., and records are already falling.

Last Friday, Illinois logged a trio of record-cold highs. Lincoln reached just 68F (20C), breaking the 70F (21.1C) from 1938 and 1926. Peoria tied its record cold maximum of 68F, last set in 1968. Springfield tied its 71F (21.7C) record from 1883 and 1926.

Then the cold shifted west.

At Dillon Airport, Montana, the high on June 28 managed just 45F (7.2C). The NWS says that is a record cool maximum for the date, comfortably besting the old 57F (13.9C) mark from 1959 (books here began in 1929).

Burns, Oregon fell to 33F (0.6C) on the same morning, matching the mark set in 1947.

This system is far from done. The same western trough remains dug in. NWS Boise has southwest Idaho and eastern Oregon running 15F below average, with some 3 inches of snow possible above 7,500 ft in the central mountains. Pocatello reports snow already observed down to 7,000 ft, with more forecast above the passes and frost/freeze conditions in the valleys.

The cold reaches well beyond the Northwest. Phoenix’s office calls the late-June setup unusually cool, with mid-level heights near the 3rd to 10th percentile of climatology and desert highs running 10F below normal.

A stark summer cold pool is holding over Alaska, northern Canada and across the High Arctic.

Alaska posted a verified cold record on July 7: King Salmon Airport fell to 38F (3.3C), breaking the old daily record of 39F (3.9C) set in 1940 and 1976 (station record runs back to 1917).

Above 80°N — the High Arctic — is where the bigger story is.

The 2026 DMI air temperature chart for north of 80°N is undercutting every year in the series (which extends back to 1958). The previous coldest summer was 2013. This year is running well below that.

Alaska’s summer cold deepened on July 9, with multiple long-running stations posting record daily maxes.

Fairbanks reached just 58F (14.4C) on Thursday, a full 16F below normal and below the previous July 9 record-low max of 59F (15C) set in 2022 (books back to 1904 here).

Nome topped out at 49F (9.4C), breaking the 51F (10.6C) record from 2024 (books back to 1906).

St. Paul Island reached only 46F (7.8C), beating the previous benchmark of 48F (8.9C) from 2020 (books to 1892).

Alaska has endured an anomalously cold 2026 to date.

So has Canada.

And also Greenland...
