Late Night Joint IOP Update

Precipitation continues but is now scattered and generally light across the Wasatch Front.  The latest radar loop suggests that a shallow layer of cold, northwesterly lies over the lake.  Radar echoes are still moving out of the southwest over much of the Salt Lake Valley, but out of the northwest over the lake.

There is one weak, wind-parallel band over the lake that make be lake induced.  We'll have to see if it continues.  We hope that we'll see bonafide lake-effect develop as we get into the early morning hours, the cold air deepens, and the land breezes get going.  Even if it doesn't, we'll have a good dataset from the polarimetric radar of a prolonged precipitation event that will be great for our students to play with.
