If you asked me a week ago about the prospects for snow tonight and tomorrow, I would have said unlikely. However, as discussed a few days ago in the Dropout Forecasts blog post, a closed low suddenly appeared in the model runs late last week and over the past few days the models have trended toward a snowier forecast for the central Wasatch. Will the model trend be our friend?
The 0600 UTC GFS suggests this will be a two part storm. Part I arrives later this afternoon as cold, moist southerly to southwesterly flow ahead of the upper-level trough pushes into northern Utah.
