As a high pressure system moves east out of the four corners region, a pacific trough will approach. A ridge over the Southwest will continue to suppress the moisture from approaching Sunday and provide dry westerly winds across most of Utah. As the ridge shifts late Sunday, this will bring considerable moisture as the southerly flow increases over the next 2 days. Unlike Saturday, Sunday will start to feel more unstable in the Wasatch and east to CO and WY. More cumulus clouds are also on tap with not much vertical development to worry about.

Lift Potential & Clouds
Top of lift mid day over the peaks near the Wasatch will likely see 14-15k feet with cloudbase slightly higher. Southern WY and Uintas expect 18k feet. Book cliffs and the San Pete range will see 15k feet or more. Shallow cumulus clouds are expected to be mainly over the higher terrain and peaks, with little over or around mountain valleys.
Expect all mountain valleys to be very stable, even mid day, especially the Uinta basin near Vernal Utah on the south slopes of the Uinta range.
Over Development & Precip
There is no potential for over development except for extreme southern Utah.
