Organizing Precipitation Band

It's been quite impressive how precipitation has organized in a line extending from central Nevada to northern Utah over the past two hours.  This has occurred south of the band that was over extreme northern Utah this morning, as anticipated by the NAM.

The full extent of the band is clearer in this satellite image, which includes a lightning strike overlay (thanks Chris A!).

Yes, we've been Thunderstruck in portions of northern Utah, but not yet in the Salt Lake Valley.

I see a lot in this case that reminds me of strong cold front events and other situations with strong confluence and convergence that extend across the Great Basin from the High Sierra.  Work is needed to better understand these events and the role of flow-mountain interactions in producing them.
