California community ties all-time March temperature record in the US

NORTH SHORE, Calif. (AP) — A tiny desert community in Southern California reached 108 degrees on Wednesday, tying the highest March temperature ever recorded in the U.S.

It came amid a record-breaking winter heat wave in the Southwest that will stretch into the weekend and could produce even higher temperatures.

The record — first reached by Rio Grande City, Texas in 1954 and now shared by North Shore, California — could be broken in a number of cities and towns by week’s end. The aptly named Thermal, California, was forecast to hit 110 degrees on Friday.

Triple-digit temperatures also came earlier than ever before in Phoenix when the Arizona capital hit 101 degrees Wednesday, according to the National Weather Service. The previous record was set almost 40 years ago, on March 26, 1988, the only other time Phoenix temperatures have climbed into the hundreds during the month of March, according to the NWS.

Bryan Lewis, a meteorologist with the NWS, said this has been one of the most significant March heatwaves in recorded history.

“We’ve broken so many records yesterday and even today we’ve broken quite a few so far,” he said.

Several cities on Wednesday experienced their hottest March day in almost 40 years, according to the NWS.

Las Vegas hit 99 degrees, smashing its hottest March day on record, which was 93 degrees in 2022.

Downtown Los Angeles reached 94 degrees, beating its previous daily high of 87 degrees in 1997.

And the desert destination of Palm Springs, California, was 104 degrees, tying its hottest March day on record from 1966.

It will continue to be 20 to 30 degrees above normal March temperatures for the rest of the week in the Southwest before dropping slightly over the weekend. Many other cities in the region are expected to see their earliest 100-plus degree day on record, according to the NWS.

Between prices and a diarrhea-causing parasite, lettuce is causing hard times at some restaurants

It’s been a choppy year for restaurants that lean into lettuce. Lettuce prices rose sharply in the first half of 2026 due to hot weather in Arizona, where about one-third of America’s lettuce is grown. Now, restaurants are dealing with the fallout from a cyclospora outbreak linked to shredded lettuce that has sickened thousands of Americans. Taco Bell will likely see the biggest sales impact from the outbreak, which began in late June. Federal health officials first tied the outbreak to shredded iceberg lettuce served at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. Later, the U.S. Food and Drug Administration said customers in Illinois, Kansas, Oklahoma and Pennsylvania were also affected. Taco Bell said on July 17 that it had voluntarily removed shredded iceberg lettuce supplied by Taylor Farms from its U.S. restaurants. But its customer volume has suffered. As of July 23, Taco Bell visits were 21% lower than average across the U.S., according to Placer.ai, a market research company.
