If you read my posts yesterday you should not be disappointed when you look outside, this was what the Euro had for snow totals by 11 am today. It is currently 6 am most mid-elevation areas have about 2 inches. I don’t think this model run from yesterday afternoon will verify at 11 am, but the point was there was never supposed to be a big amount of snow overnight.
Yesterday I also shared my concern regarding snow below 7,500 feet today. The latest model runs show quite a bit of a lull later this morning then later this afternoon a few bands of heavier snow come through, again this may not materialize at the lower elevations. I also mentioned that Thursday may provide some relief for people who are traveling short distances for the Holiday, that is the upside of all of this.
The bigger portion of the storm has always been on Friday, and I think that temperatures may continue to be an issue for lower elevations, basically anyone below 8,000 feet will struggle until the front gets near enough to us to tap into the colder air, at that point, one of two things will happen, the front will either stall and strengthen or it will weaken and speed up.
Here are the latest highlights from the NWS, read my comments afterward.

The biggest takeaway is they changed the amounts for the lower elevations from 4-8 to 3-6 inches and they changed the start time from 5 pm Thursday to 5 am Friday. They also changed the “up to 40 inches” to “up to 60 inches above 10,000 feet on south-facing slopes” that could happen but if it does it will likely be up in the La Platas and in uninhabited southern Hinsdale County
From what I see in the overnight models I would be on the low side of all of those totals, I will update again after I see some of the morning models.
