We're operating radars and collecting sounding's of today's storm as part of the SNOWSCAPE2026 field campaign. The data coming in from the Huntsville radar is spectacular. Below is what is known as an RHI (Range-Height Indicator) scan, which involves rotating the dish vertically rather than horizontally to take a vertical slide through the storm. This RHI essentially represents a vertical cross section taken toward the WSW from the Hunstville radar (bottom left) across Snowbasin, and eventually over the Great Salt Lake lowlands upstream.
The radar can't see through mountains, which show up below as pink and white color fill due to their high "reflectivity". I've highlighted Snowbasin where the terrain slopes up from about 1.5 to 2.75 km in heght.
Evident in the RHI are four generating cells that extend to near or above 5 km above sea level. These are moving across Snowbasin and then downstream into the Ogden Valley where they are producing rain and at times some graupel.
We're getting some great data today of small scale convective cells interacting with the northern Wasatch.
