Bear with the Sunday heat — a more spring-like cool is days away.
A Pacific storm system will slowly cross Utah from late Monday through at least Wednesday, bringing much cooler temperatures and showers, according to the National Weather Service in Salt Lake City. There will also be a chance of isolated thunderstorms.
After an expected high around 80 degrees on Sunday, the Wasatch Front cools to about 60 degrees on Wednesday and Thursday. St. George, meanwhile, will see temperatures drop from about 93 degrees Sunday to about 70 degrees by Wednesday.
Before the storm arrives in Southern Utah, though, experts warn that certain areas are under a red flag warning because of the gusty winds and low relative humidity. The warning lasts until 10 p.m. Monday, and includes St. George.
