After a relatively dry Friday, multiple storms will impact the region over the next 7 days.
Accumulating mountain snow will begin tonight, heaviest across the southern mountains. A winter weather advisory has been issued for the southern mountains beginning late this evening and continuing through Saturday morning.
Additional storms will impact the Beehive State Tuesday into Wednesday and potentially Thursday into the weekend.
.DISCUSSION, Issued 1059 PM MST Thu Nov 12 2026. A high-amplitude ridge has shifted east of Utah into Colorado this evening while upstream, a couple of storm systems are noted on water vapor satellite imagery. One is a closed low off the SoCal coast, while a second, larger, closed low is approaching the PacNW. The southern low will be coming onshore near the Cal/Baja coast by midday Friday. This system will gradually weaken as it becomes absorbed into the southerlies that will strengthen ahead of the second storm, which will continue to make its way onto the PacNW coast on Friday. The two storms will eventually phase into a negatively tilted trough which will then cross Utah Friday night through Saturday.
Given the increased southerly flow, some moisture will spread north into Utah on Friday ahead of the southern stream storm. As such, expect isolated to scattered showers to develop Friday afternoon into Friday evening. This will take place under a relatively mild airmass, with snow levels remaining mostly above 8500 ft during this timeframe. Precipitation will then become more widespread Friday night through Saturday morning ahead of and with a relatively fast-moving cold front. Snow levels will quickly fall to around 6-7 kft by around midday Saturday. However, precipitation will mostly wind down by late morning or midday Saturday behind the cold front, with the exception of the mountains, particularly those areas favored in northwesterly flow, which will maintain brief orographics into the afternoon. Additionally, with warm temperatures over the GSL, expect some showers to continue developing of the lake into the central Wasatch Front and adjacent mountains as well.
Most valleys are expected to see storm total precipitation amounts between 0.4-0.7 inches near the I-15 corridor and less elsewhere. Meanwhile, mountains are expected to see 0.6-1.2 inches with locally higher amounts in the upper Cottonwoods and near Brian Head. Snow amounts remain generally in the 4-8 inch range, mainly above 7500 feet, with higher amounts possible in the upper Cottonwoods, Tushars, and near Brian Head.
