Forgot to mention that winds will be a factor, especially Sunday and Sunday night and perhaps Monday. Could see some lift holds. FYI…
Snow is falling over most Utah mountains this morning and will continue until afternoon before tapering off. A break tonight into tomorrow morning, before the next storm brings significant snow to the region Sunday afternoon thru Monday night.
Our second “weak” storm is delivering more snow than expected to the region. Plenty of moisture was pulled up into the region overnight in a SW flow. Not surprisingly, Brighton got the most snow with 17″ of fresh. That SW flow has now switched to NW and LCC and other regions are getting pounded currently. The snow will continue this morning and taper off sometime this afternoon. Another 3-6″ is likely by afternoon.
A break tonight into Sunday morning as the next system approaches.
Next storm pushes in on Sunday afternoon with snow developing in a SW flow. Snow will continue Sunday night and Monday. The flow will switch to a NW flow on Monday behind the front. You can see the 12km NAM is predicting an additional 20″ of snowfall for the Upper Cottonwoods:
Looks good to me!
You can see the best areas of snowfall in the following map, the Sierra Nevada will be winning the battle with this storm, with 3-6 FEET of additional snowfall. But in Utah, the highest amounts will be in the Northern Mountains with 1-2 FEET of new snow and the southern Utah mountains will also see hefty totals with 1-2+ FEET down there as well.
We’ll have a cold unstable NW flow continue thru at least midweek. That means that snow showers could stick around for quite some time after the storm has passed. Ridging will eventually develop for later in the week into next weekend.
The ridge will be in control for 5-7 days, but indications remain that the ridge will be replaced by a trough at some point in the first few days of February. This is still out-of-range of operational models, so we can’t offer any details. But it doesn’t look like a long-term ridge like we’ve seen in years past.
