A cold storm is moving through the area today into tonight. Not a huge storm but snow could pile up quickly, especially in areas favored by a northwest flow (Cottonwood Canyons). We see a break in the action starting Tuesday.
Our current storm is moving in…. Snow showers ahead of the front are just beginning in areas south of I-80… areas farther north already reporting an inch or two…
Snow showers this morning with be disorganized and probably off and on in nature. The front will move in from the north through the day and so too will more organized and heavier precipitation. For most locations, especially those in the SLC/PC area, today is a LAST chair powder day. The best powder skiing from this storm will likely be tomorrow morning.
Snow should continue into tonight, with the best dynamics dropping down to the Southern Wasatch. The wildcard is lake effect / enhancement which is a possibility southeast of the GSL. No need to change totals posted yesterday for this system, these amounts are through Monday afternoon:
- Cottonwoods: 10-15″, highest amounts in LCC
- Snowbasin / PowMow / Beaver Mountain: 6-12″
- PC resorts: 6-12″
- Mountain valleys: 3-6″
- Wasatch Front valleys: 2-4″, up to 6″ on benches
IF the lake does get involved, totals could be higher southeast of the lake, which would include parts of the Salt Lake valley and the potentially the Cottonwoods.
The system will drop south of the region by Monday night. This Low pressure will close off down in southern California and Arizona where it will spin its wheels for a couple days. This will create a potential for a downslope wind event with the easterly flow. By Wednesday, snow could spread into far southern Utah again. Brian Head could see a powder day for Thursday. If you’ve got New Years Day off, might want to consider a trip down south if things work out for them… I’ll keep you posted.
Northern Utah will remain dry after Tuesday. Models showing little agreement on the long range. The GFS wants to drop a moist, northwest flow into far northern Utah next weekend. The Euro keeps this north of the area, then nudges stronger high pressure into the west that would keep us dry for awhile. The GFS breaks under the ridge next week and brings stronger systems into the western conus (continental U.S.). The GFS has been more consistent, but the Euro is often the first model to catch on to new trends. In this case we definitely want the GFS to be right. Needless to say, I have very little confidence in saying anything other than “We’ll be dry from Tuesday thru at least Saturday this week”. Beyond that is a mystery right now….
