As do most (but not all) forecasts valid 1200 UTC 27 November (0500 MDT Wednesday).

When one here's the phrase "pattern change" there is a tendency to get excited when we've been persistently warm and dry this time of year. I like to keep calm and carry on. After deducting totals for today, the NAEFS ensemble forecasts through 0000 UTC 28 November (1700 MDT Wednesday) generate a mean of about 30 inches of snow at Alta Monday, Tuesday, and Wednesday, but this number is jacked up by several Canadian Members that produce huge, unrealistic totals. The GEFS mean (red line) suggest around 18 inches, but the GEFS range is also between about 8 and 30 inches for the period.
