It's not just warm out there in Utah — it's record-breaking.

High temperatures broke or tied records Sunday in 10 cities in Utah, according to National Weather Service data.

The mercury hit 86 degrees at Salt Lake City International Airport by Sunday afternoon, breaking the 83-degree high mark for the day set in 1934, said NWS meteorologist Mike Conger.

The oldest record broken was in Kanab, where temperatures soared past a 1929 record of 87 degrees to 90 degrees on Sunday.

In St. George, the statewide high temperature was a scorching 97 degrees, compared with a normal reading of about 78, said weather service meteorologist Eric Schoening.

The heat is due to a strong high-pressure system with a much warmer air mass than is typical, creating temperatures more like those seen in mid- to late June, he said. Monday also is expected to be hot, though maybe not record-breaking.

"The wild card will be if we get late afternoon cloud cover," Conger said.

This isn't the first record-breaking day this month. On April 10, meteorologists recorded a high of 81 in Salt Lake City that beat the old record of 78, set in 2003.

Don't get too used to the early summer temperatures: The mercury is predicted to dip again near the end of the week, down to a forecast low of 39 degrees in Salt Lake City Friday.

"That's pretty typical of spring," said Schoening. "We'll have warm days followed by periods of rainy, cool weather."
