Utah forecast: Not ‘The End,’ but yes, St. George about as cool as Salt Lake City

First Published      Last Updated May 09 2017 08:06 am

Blink once, blink twice, but it's still true: temperatures in northern Utah, where snow still caps the Wasatch Mountains, will match those of the state's arid, sunny south through the midweek.

Temperatures in both Salt Lake City and St. George will be in the mid-70s Wednesday, a repeat of Tuesday's forecast.

Ironically, Salt Lake City's highs through the midweek will run about 5-7 degrees above then norm for this time of year. Meanwhile, St. George will be 10 degrees or more below normal for Utah's Dixie — and both locales will be decidedly wet.

Still, there's no need to cue the massive earthquakes, dodge fireballs from heaven, or keep watch for the umbrella-wielding Four Horsemen of the Apocalypse clip-clopping around the Capitol grounds.

The National Weather Service blames the low pressure system out of northwestern Mexico, and "high pressure aloft" over the Great Basin for the rare similarities of forecasts for northern and southern Utah.

That means showers and thunderstorms along the Wasatch Front Wednesday, continuing the wet weather of Tuesday afternoon. Thursday will begin a drying trend and the mercury will flirt with 80 degrees in Salt Lake City.

The same cycle of rain, punctuated by winds of 10-20 mph and lightning, will rule the redrocks and high deserts of the south through the midweek. Thursday will dawn sunny and dry, however, with highs in the mid-80s.

The Utah Division of Air Quality rated breathing conditions statewide as "green," or healthy, with the sole exception of Washington County, which was "yellow," or compromised for particulate pollution levels.

The Intermountain Allergy & Asthma website listed mulberry at "very high" and sycamore and oak "high" on its pollen index as of Tuesday. Other allergens were either "low," or did not register on the site's pollen index.
