Utahns looked for an unseasonably warm, sunny and dry Thursday, then everything changes. A storm system, rolling in from the Pacific Northwest, will bring valley rain and mountain snowfall to the region.

High temperatures on Thursday will range from near 60 degrees along the northern Wasatch Front to a downright balmy low-70s in southern Utah — in both cases, a few degrees toastier than Wednesday.

Come Friday, however, storm clouds will build along northern Utah's horizons. As rain pelts the lower elevations, 3-4 inches of fresh snow were expected to blanket the Wasatch Range; daytime highs were to dip into the low- to mid-50s.

Keep in mind, as long as it's not a Simpsonsesque acid rain, the precipitation is a good thing: this winter has been unusually lacking in rain and snow thus far, and that naturally stored water is critical for Utahns come summer.

Untouched by the wet weather, Utah's Dixie looked for another sunny Friday with highs in the low-70s — confused wildlife, or not.

The Division of Air Quality rated the entire state as "green," or healthy for breathing extending into the coming weekend.

The Utah Avalanche Center rated the risk for potentially deadly backcountry mountain snowslides as "low" throughout the state as of Wednesday.
