I saw that one recently as well..
Not sure how valid their predictions are yet. They are calling for 3-8 inches above 6000K but the NOAA weather.gov is listing less than two inches at Brighton.
If I had to gamble I would put my money on the NOAA rather than Wasatch snow forecast..
I hope wasatch snow forecast has the better predictions though, since they're predicting 3-8 Tuesday, 10-18 Thursday-Friday, more to come next Monday-Tuesday but no total predictions.
