Sweltering heat blankets the Beehive State, heat warnings in place

SALT LAKE CITY (ABC4) — Happy Wednesday, Utah! The sweltering heat is blanketing Utah, prompting several heat warnings across the state.

High pressure continues to strengthen over the region and is now centered over the southern Great Basin. The ridge is continually generating very hot and dry weather for our area.

As the ridge nudges eastward, temperatures in northern Utah will be hotter today, with most cities along the Wasatch Front reaching over 100 degrees. Salt Lake City is expected to hit 103 degrees this afternoon, 10 degrees above average.

In southern Utah, temperatures will also climb, pushing Cedar City over 100 degrees and St. George and Zion Canyon between 112-115 degrees.

By Thursday, the ridge will be directly over the state, adding a few more degrees to daytime highs. There is little relief from the heat through the rest of the week, even with some cloud development in the forecast. Dry weather will persist through Friday with more record-potential heat.

In addition to the high heat and dry weather today, we also see an increase in northerly winds which adds to an increase in fire danger. Red Flag Warnings are in effect for parts of Central Utah and the Color Country Mountains. The warning holds through 9 p.m. and winds of 10-15 miles per hour are expected with gusts of 20-25 miles per hour.

Relative humidity will be as low as 6% which means that wildfires will spread at a rapid pace if they start. These critical fire conditions will occur near large wildfires already burning and could make it a tough day for fire crews and cause erratic fire behavior.

The heat wave will continue on Friday as a strong ridge settles over Utah, bringing record-breaking temperatures. Temperatures across the Wasatch Front will soar to possible record highs with 106 degrees forecast on Friday for Salt Lake, the current record is 105 degrees from 2003.

There’s even a chance of breaking the all-time high of 107 degrees on Saturday in Salt Lake with 107 degrees in the forecast right now. St. George will remain very hot with highs above 110 degrees through Friday, with slight cooling expected on Saturday due to increased mid-level moisture. Most areas will see limited overnight relief, increasing the risk of heat-related illnesses.

Above-normal temperatures will persist into next week, but the ridge will shift east, allowing for slight cooling and the return of some moisture. Limited moisture might bring isolated thunderstorms to southern Utah on Saturday, with better chances for measurable precipitation and storms moving north by Sunday. This pattern may continue into midweek.
