Ma Nature's unseasonal case of the chills had northern Utahns hurriedly retrieving their cold-weather gear from the closets.

That's late spring for you in the Rockies, where thermometers dance like befuddled spring sprites from the 90s one day under clear, sunny skies only to tumble 35 degrees or more under snow-laden, dark clouds the next.

Summer officially begins on Saturday, but on Wednesday the National Weather Service still issued a Winter Weather Advisory for the Wasatch Mountains north of Interstate 80 — a region stretching from Logan south through Brigham City and Ogden into Salt Lake City — as well as northeastern Duchesne County.

At 8,000 feet elevation and higher, forecasters predicted up to 2 inches of snow would be added to the half a foot or so that fell under similar conditions on Tuesday.

In northern Utah's valleys, the unseasonal cold front translated to rain showers and high temperatures in the 60s on Wednesday. That was to give way to highs in the upper-70s under sunny, mostly clear skies on Thursday.

Farther south, there was less meteorological confusion at work. Utah's Dixie looked for lows in the mid-80s Wednesday under clear, sunny skies. Thursday's forecast was for more of the same, with temperatures 5 to 7 degrees warmer.

Heading toward the end of the work week, the Utah Division of Air Quality rated Salt Lake, Davis, Utah and Washington counties at "yellow," with the rest of the state earning "green," or healthy grades.

The Intermountain Allergy & Asthma website's pollen index on Wednesday was "high" only for plantain, with grass and mold at "moderate" levels.
