Utah Weather: June 4, 2021



SALT LAKE CITY (ABC4) – Good Friday! Prepare for the extreme heat! Another day when heat records will drop, and Salt Lake City could hit its first 100 degree day of the year.

This would be the first 100 degree temperature in Salt Lake City history and is about 20 degrees above average for this time of year.

Above-average heat will take hold of all of Utah with a series of high 90 degrees along the Wasatch Front, Uinta Basin, central Utah and higher elevations of southern Utah .

Triple-digit heat is returning to Washington County and St. George. This will be the third day in a row that St. George has climbed above 100 with a high of 105 expected.

An “excessive heat warning” is still in effect for lower Washington County and Lake Powell until Saturday night. The heat advisory issued for the Wasatch Front has been upgraded to an “excessive heat warning” for the Wasatch Front and the Western Desert with triple-digit numbers targeting these areas.

A new heat advisory had been issued for the Tooele and Rush valleys, Sanpete and Sevier counties, the western basin of Uinta and parts of the north.

There is a slight chance that dry thunderstorms could impact parts of the Western Desert with the heat of the day. We will also see high levels of ozone creating unhealthy atmospheric conditions in places like Utah and Salt Lake counties.


The maximum heat is here with this high pressure ridge, and the temperatures will be extremely hot if you are outside for an extended period.

In addition to the extreme heat, the fire danger will increase through the weekend with a “red flag warning” going into effect on Saturday with increasing winds.
