Reflectivities are consistently high upwind (south) of South Mountain over the Rush Valley, but there's a sharp gradient in reflectivity over or just to the lee (north) over the Tooele Valley. Even small, narrow ranges like South Mountain can have a dramatic influence on precipitation if they excite high amplitude mountain waves with strong subsidence in their lee, which appears to be the case today. I wonder if it almost looks Foehn-like if one looks south toward South Mountain from the Tooele Valley.
Precip totals since midnight near the crest of the Wasatch Mountains are very consistent with expectations during large-scale southwesterly flow. Big values on Ben Lomond and in the northern Wasatch, and then further south around Timpanogos, Cascade Mountain, etc. From north-to-south (SWE in inches):
- Ben Lomond Peak: 3.6
- Snowbasin Middle Bowl: 1.41
- Alta-Collins: 0.71
- Aspen Grove: 1.57
- Cascade Mountain: 1.5
Bummer that we don't have access to a reliable precip site on the Park City side of the range.
