Utah and southwest Wyoming remain between two troughs this morning on satellite imagery, resulting in largely quiescent conditions under a dry, stable air mass. Isolated areas of fog developed early this morning given calm and clear conditions, but is unlikely to return tonight given increasing mid-level clouds ahead of the trough to our west that will limit surface cooling. As that trough continues to close off over the Great Basin, precipitation chances will increase first over the West Desert by early Wednesday morning, shifting over northern/central Utah by late morning. Low-level flow will become more northeasterly through the day, moreso favoring measurable precipitation over the Wasatch Back and areas east rather than the Wasatch Front. Still, precipitation amounts will be minimal, with the 75th percentile (25% chance of exceedance) showing around 0.25" of rainfall near Park City/Heber City. High temperatures tomorrow will be around 5-10 degrees below normal as this system brings cooler air into the region. Following this storm system, this cooler, yet dry air mass will stick around through the work week as largely cyclonic flow dominates the western US. As skies clear later this week, we will need to monitor valley fog chances, particularly given above- normal soil moisture across the area. Over the weekend, a steady warming trend is expected as high pressure builds, with temperatures approaching 5-10 degrees above normal by Monday. Ensemble guidance suggests our next precipitation chances won`t return until at least the middle of next week. && .AVIATION... KSLC...VFR conditions will persist for the KSLC terminal through the period. Dry conditions will persist overnight before a weak storm moves through during the day tomorrow with lowered CIGs and brief light rain showers with mountain snow and obscuration. Light northerly winds will transition to light southerlies overnight before a return to light northerlies during the day tomorrow. REST OF UTAH AND SOUTHWEST WYOMING...Mostly VFR conditions will persist for the entire airspace through the period. Dry conditions overnight will give way to isolated showers during the day across the central and northern airspace as a weak storm moves through. Mountain snow and lowered CIGs will result in mountain obscuration. Winds will be light and diurnally driven. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None.
