Thusfar this year, the Cottonwoods have really cleaned up during most storms. This morning, however, Mount Timpangos is getting the action. Check out the latest radar loop, which shows an area of high radar reflectivity sitting over the Timpanogos ridge and environs.
A quick look at the morning sounding from KSLC shows a shallow cold pool below 775 mb. Above this layer, however, the flow is southwesterly to about 600 mb, which results in maximum upslope flow on the west face of Mount Timpanogos.
Of course, the question that remains is why is Timpanogos lighting up compared to areas favored in southwesterly flow, such as Ben Lomond? Something to ponder.
