Outlook
Our storm system will continue to clear out this evening and overnight lows will be cold in the 30s along the Wasatch Front. We'll have mostly sunny skies Tuesday with just some clouds bubbling up over the ridges. Highs will be around 10 degrees cooler than normal around 64 degrees. Wednesday and Thursday will have highs near 70 degrees, but there will be a 30% chance of showers for the northern half of the Wasatch Front on Thursday. This is thanks to a storm system clipping the northeast section of Utah. Friday and Saturday may have some weak disturbances passing through but right now confidence is low on that, and if anything these precip chances will be limited to the mountains. Temperatures will warm nicely into the 80s for Memorial Day weekend! - Devan Masciulli, KSL Weather 5.18.26
