Take heart, Utah. The sun'll come out, tomorrow. And just thinkin' about tomorrow clears away the cobwebs, and the sorrow . . . of pollution-trapping winter inversions along the Wasatch Front.

Tomorrow, of course, being Saturday. Until then? Sorry, Annie — the Utah Division of Air Quality says Friday will be another "Red," or unhealthy day to be outside for the very young, the very old and those with lung or heart ailments.

Friday's forecast of dirty haze and highs in the upper-30s in northern Utah will see a dramatic change come Saturday, with patchy morning fog giving way to sunshine and fresher air aloft. Highs will once more be in the upper-30s.

With the improved weather will come statewide "Green," or good air quality grades.

Drive a few hours south and you could get a foretaste of spring. Southern Utahns looked for highs in the upper-50s to low-60s on Saturday, mirroring Friday's forecast. Clear, sunny skies will be the rule this weekend for Utah's Dixie.

Plan some backcountry skiing, snowboarding or snowmobiling? The Utah Avalanche Center warns that the risk for potentially deadly snowslides remains elevated going into the weekend: "considerable," in fact, for the mountains around southeastern Utah's Moab, while the rest of the state's slopes earned a "moderate" avalanche risk grade.

Salt Lake City's forecast high of 37 degrees Friday foreshadowed a 38 on Saturday; Ogden expected 36 and 37 degrees, respectively; Provo 41 and 44; Logan 32 and 31; Wendover 40 and 38; Duchesne 34 and 31; Cedar City 44 and 53; St. George 63 and 64; and Moab 44 and 47 degrees.
