I read about it last night. Said cold air had just settled in the day before? and precip exploded on the “cool” side just on the east side of the mountains. Lee side trough? I think that was a low probability event but it was a good one. Roads were wet but trees and grassy areas were caked!I was just talking about this with someone on twitter but it was a strange setup, had a outflow boundary and acted like a MCS, setup I’ll never forget
