The post-frontal phase of our storm last night produced mostly lake-effect precipitation, which at times organized into wind-parallel bands.
Note how the coverage, structure, and orientation of the lake-effect is quite variable. There is no computer modeling system or forecaster that can reliably predict such variability. This is why it is so difficult to provided detailed lake-effect forecasts. About all you can say is that lake-effect is possible downstream of the lake, but we don't know the details of where, when, and how much.
It is pretty variable that's for sure. I got 6 inches from the lake band last night... didn't melt it down but i bet its 15 or 20:1 ratio.
ReplyDeleteNot sure if anybody else has been looking at the radar, but there are very light echoes if any near the U and it has been snowing fairly hard outside for awhile. The large snow particles (looks like dendritic aggregates out the window) must be in a pretty shallow layer for the radar beam to be missing them. Makes me think the snow crystals are growing quite rapidly.
ReplyDeleteI came down from Solitude around 4PM where is really wasnt snowing and the sun disc was visible. Clouds increased down canyon and snow was falling. Snow was falling below 7000ft.
