Snow, rain means sloppy Tuesday for Utah
SALT LAKE CITY (ABC 4) – What a messy Tuesday! A sloppy day is shaping up with wet weather continuing with more rain and snow as temperatures are more like November than October. Daytime highs will not reach until the 1940s for much of Utah – even St. George will not reach until the 1950s.
We see the coldest air of the season this evening, with an intense frost watch for the northern Wasatch front, the Tooele and Rush valleys, the Eastern Box Elder County, the Utah Valley, the Western Uinta Basin, Castle Country and Western Canyonlands. Frost will mark the end of the growing season with nightly lows falling to 28 degrees or below.
We also have a host of weather warnings in effect as an unusually cold fall storm for the season continues to usher in winter weather. This powerful storm system has triggered widespread rainfall and will impact the state until Wednesday morning. This storm triggered a “winter storm warning” for most of our mountains, along with a “winter weather advisory” for some higher elevations in the north, as well as in the central and southern valleys of Utah. The winter storm warning will remain in effect until 6 p.m. Tuesday and will affect the western Uintas, the central mountains, the southern mountains, parts of southwestern Utah and the eastern part of the counties of Juab. and Millard.
Winter driving conditions are expected, particularly on I-15 from Nephi to Cedar City. Snow accumulation is expected, between 4 and 8 ″, in these areas with localized areas approaching 10 ″. This could result in dangerous road conditions on parts of I-15 and I-70 corridors. Additionally, as cooler air enters, severe freezing conditions will be possible in parts of the southwestern half of the state this evening. The winds will also be gusty so southwest Utah could face blowing snow making driving conditions extremely dangerous on I-15 throughout the San Rafael swell, from Scipio to Cedar City, and on all mountain roads. The driving conditions will more closely mimic the road conditions in January, as opposed to October.
The winter weather advisory will also remain in effect until 6 p.m. Tuesday and will impact the Wasatch Mountains, Sanpete Valley, Sevier Valley, Upper Sevier River Valleys, Bryce Canyon Country, the Capitol Reef National Park and surrounding areas, West Juab and Millard counties, and East Uintas. Snow accumulation is expected in these areas with varying totals. The National Weather Service issues a winter weather advisory when periods of snow will primarily cause travel difficulties. Expect snow-covered roads and limited visibility, and be careful when driving.
Winds will also be an issue starting Tuesday morning, particularly with gusty crosswinds expected on I-80, with a wind advisory coming into effect at 6 a.m. the way to the border between Idaho and Utah. Expect sustained cold northerly winds between 20-30mph with gusts of up to 50mph. The notice will expire at 3 p.m.
In addition, from Tuesday evening to Wednesday, the humidity will start to come out, leaving just a small chance of humid weather for the middle of the week. However, another swift system will bolster the cold air for Thursday and bring with it another chance to see snow showers across the state. After Thursday the sun seems to come back as we follow a slow warming trend over the weekend.
