The National Weather Service has issued a hard freeze warning covering portions of northern and central Utah for late Wednesday and early Thursday.
The advisory includes the Salt Lake and Tooele valleys, where sub-freezing temperatures — in places as chilly as the upper-20s — were expected. The warning also applies to the southern Wasatch Front and the San Rafael Swell region.
Daytime temperatures Wednesday and Thursday were forecast for the upper-40s to low-50s in northern Utah, while southern Utahns expected to see the mercury dip into the low-60s.
The state Department of Environmental Quality issued “Green” or healthy air ratings for all of Utah.

Also of concern were southern Utah’s S.R. 153 east of Beaver, S.R. 20 near its summit, S.R. 143/14 east of Cedar City and S.R. 12 over Boulder Summit.
