TL;DR: Storm Saturday/Sunday/Monday. Cold Tuesday.
Nowcast:
Slightly out of date, but an official and easy to copy list of storm totals is shown below.
According to the NWS, accessed via the Iowa Mesonet, as of 5am Saturday morning the storm reports were 10-18" of FRESH south of I-80.
Powder Mountain and Snowbasin did great as well, with 15 and 9 inches respectively.

For those who WEREN'T stuck in the classic Red Snake of LCC, or discovered the NEW Red Snake heading into Snowbasin.. I salute you. Personally I went to get some pictures framed and dodged the whole mess.
Last night's storm wasn't without mother nature, further down in the same report wind gusts are measured around 60 mph, occuring either mid afternoon or 8-10 pm last night:
...Wasatch Mountains South of I-80... Canyons - Murdock 75 MPH 0800 PM 01/12 40.69N/111.60W/9299 Empire Peak 67 MPH 0105 PM 01/12 40.61N/111.53W/9569 Reynolds Peak 67 MPH 0850 PM 01/12 40.66N/111.65W/9399 DV - Mount Baldy 66 MPH 0450 PM 01/12 40.61N/111.48W/9347 2.5 NE Brighton (PCMR) 62 MPH 0800 PM 01/12 40.63N/111.53W/9209 Alta - Top of Collins 62 MPH 1000 PM 01/12 40.57N/111.63W/10442 Cardiff Peak 61 MPH 0430 PM 01/12 40.59N/111.65W/10059 Provo Canyon 61 MPH 0850 PM 01/12 40.34N/111.60W/5182
Now, 330pm ish on Saturday, we're looking at valley temperatures in the high 30s, BCC mid 20s, and LCC/Park City cooler just below 20. Ridgetop winds are from the SW, 14-20 mph. I circled the ridge-stations, canyon sites are doing the usual up/down blowing:

Short term:
The active pattern continues with 500 mb heights showing winds out of the west / northwest through Sunday morning:
 |
| 500 millibar (upper atmosphere flow) from the NAM (North America Model) for Sunday Morning. A single spot-forecast out of the NAM near Alta shows precipitation starting around now, throughout the night, increasing around midnight and slowly tapering off through the day. Temperature will stay 'as is' through the night into tomorrow, before the potential for a cold front coming through Monday night. Winds from the South could deposit snow and move things around to unusual places, that shifts after midnight to 'usual' westerlies around 12 mph. |
Long term:
Things are going to be dumping through Sunday and into Monday, wrapping up Monday night when an arctic air mass breaks into the region (you're welcome).
Backcountry comments:
The rose is red and scary because things are active and sliding. The UAC says it best:

Large amounts of recent storm snow are sensitive to human triggers and widespread through all aspects and elevations, especially in lower-elevation and tree'd areas.
If you will be traveling in the backcountry make sure you have the proper equipment and know before you go. For the whole avalanche forecast and all things avalanche head over to our friends at the Utah Avalanche Center here: Utah Avalanche Center
