|Looking west from the Avenues ~640 PM MDT|
The National Weather Service presently has a severe thunderstorm warning issued for portions of Tooele County, and I suspect that they may issue one soon for portions of the Salt Lake Valley and Utah county.
The strong cell moving through the Rush Valley in the south of this loop is likely severe. It is moving rightward relative to the other cell tracks and even shows a bit of a hook-type structure. Radar reflectivities are very high, above 70 dBZ at the end of this loop (white color shading). It is certainly producing large hail and strong winds. I won't be surprised if someone spots a funnel cloud or tornado with this system.
