A snow advisory continued Wednesday over southeastern Utah and adjacent mountains.

A low-pressure system over northern Arizona is continuing to pump moisture into southern Utah. As the system moved eastward Wednesday it was expected to affect primarily southeastern Utah, where snow fell most of Tuesday night and early Wednesday.An additional 1 to 3 inches or more of snow is possible in that area Wednesday. Blanding received 2 inches of snow and Monticello 6 inches during the night, and it was still snowing early Wednesday. But not much had accumulated between sunrise and 10 a.m. Wednesday.

Roads in the area are snowpacked and slick. Some trucks were having difficulty making it over steeper grades, said Alex Smith, a lead forecaster at the Salt Lake office of the National Weather Service.

In the Salt Lake-Ogden-Provo area, 20 to 30 mph or higher easterly canyon winds prevailed Wednesday morning. Centerville had gusts to 44 mph Tuesday evening; Holladay, 34 mph gusts Tuesday afternoon; and Hill Air Force Base, 35 mph gusts Wednesday morning, said William J. Alder, meteorologist in charge of the Salt Lake office.

Wednesday night there will be increasing clouds, and the temperature won't be quite as cold. Low readings will be in the low to mid-20s. It will be mostly cloudy Thursday. Highs will be near 50 degrees.
