Forecast: High pressure to bring weekend of gloomy air

First Published      Last Updated Jan 15 2014 12:57 pm

A high pressure front that settled over northern Utah means a return to colder temperatures and pollution-trapping air inversions heading into the weekend.

Indeed, the Utah Division of Air Quality rated all areas of the state, with the exception of southwestern Utah's Washington County, as "yellow," or moderate for breathability on Thursday and Friday.

Forecasters warn that will likely not improve, and could worsen, as urban valley smog increases through the weekend.

The National Weather Service predicted high temperatures Thursday will dip into the mid- to upper-30s after Wednesday's forecast for highs around 40 degrees. Overnight lows were pegged in the upper-teens.

Southern Utahns had it made, though, with highs in the low 60s and overnight lows around 30 degrees.

The Utah Avalanche Center issued an Avalanche Warning for the western Uintas and Logan area mountains, advising winter recreationists to simply avoid the backcountry entirely. Both of those districts earned "red," or high risk ratings for potentially deadly snowslides.

The mountains above Salt Lake City, Ogden and Provo were assigned "orange," or considerable risk grades, while the Moab district was "yellow," or moderate.
