Expect rain in northern Utah, and there is a red flag warning in southern Utah.
After record-breaking heat in Salt Lake City on Thursday, temperatures are expected to be 10 to 20 degrees below normal over Memorial Day weekend, according to the National Weather Service. And the forecast says rain, rain and more rain.
This was after temperatures rose up to 15 degrees above normal on Thursday. It reached 92 in downtown Salt Lake City, breaking a record of 87 set in 2006. It was 94 at Salt Lake City International Airport, breaking a record of 92 set in 1958.
City Creek (85) set a record in 2001; Eskdale (92) set a record in 1974; Provo/BYU (93) set a record from 2001; and Scipio (91) set a record of 1900.
The forecast calls for sunny skies on Friday and temperatures a few degrees above normal — in the mid-80s — in northern Utah. And then a storm system will move out of the Pacific Northwest Friday night and temperatures will drop. A high of 70 is expected in Salt Lake City on Saturday, falling to 60 on Sunday and 58 on Monday — 20 degrees below normal.
There is an 80-90% chance of rain on Saturday and Sunday and a 70% chance on Monday.
No rain is forecast for southern Utah, and the National Weather Service has issued a red flag warning for much of that part of the state from 11 a.m. Friday to 10 p.m. Sunday. Wind speeds of 15-25 mph gusting up to 45 mph are expected with a daytime humidity of 5-10% creating the possibility of critical fire conditions.
The affected area includes St. George, Cedar City, Zion National Park, Bryce Canyon National Park, Escalante, Moab and Green River.
Temperatures will also drop in southern Utah. In St. George, the forecast high is 98 on Friday, 92 on Saturday, 84 on Sunday and 78 on Monday. Normal highs for this time of year are 90-91.
