I know you all are dying to know the latest on the impending storms, so lets cut right to the chase.
The forecasted high temperature today in the valley today is 60 degrees (what?!). 20 degrees above normal for this time of year! Though, later this evening, the winds will pick up and the temperatures will drop quickly. A short wave bringing a quick pulse of energy is forecasted to quickly move across Northern Utah tonight. Light rain and possibly snow along the benches should continue into the early morning. The higher elevations could receive a dusting to 1-2″. Now getting to the good stuff
First Round: Tomorrow evening the Salt Lake Valley should experience a frontal passage right around 5-6pm (00 UTC Friday). Most of the snow that falls will be of the post-frontal variety. There isn’t an excessive amount of moisture with this system, but wind will be from the NW and crest level temps are low (-10 to -11C) so snow to liquid ratios will be high. I feel confident in forecasting 5-9″ for the Cottonwoods through Friday, but as always, I’d be happy with more!
Second Round: This system has less certainty accompanying it since it is approximately 100 hours out from the 12 UTC model runs from this morning. What seems certain as of now is that sometime Sunday night a second frontal passage will make its way across the state. Snow will begin falling Sunday night and showers should persist as this trough appears to want to stick around through Tuesday. It is still too early produce reasonable snow estimates from this storm, but QPF totals from the GFS and Euro are suggesting the possibility for some great powder days early next week. We will be able to hammer out some more precise details for you as we head into the weekend.
Now, just gotta get through humpday and pray for powder.
