Next Up The Frontal Passage

12/10/21 Friday 6 am

I am going to blame this later than expected post on the power outage. I slept through it.

160 westbound is sporty this morning. Chain laws are in effect. We have not had that happen in a couple of years. Here is Hesperus Hill a couple of miles west of me.

I have had 13.75 inches of wet heavy snow here. The last batch was pretty compacted so in actuality, I probably had a little more. Reports are slow to come in so far this morning, but I am keeping track of them. So far, I just got a report from Haviland of 18 inches, 3.5 in town in Durango, and 6+ in Bayfield with snow still coming down. Purgatory is reporting 25″ in 24 hours. Be careful on your way to enjoy that. Telluride’s early report was 11 inches overnight and 15 in the last 24 hours. Wolf Creek does not typically report early, so we will see.

Over the next couple of hours, the cold front will be moving through. It certainly has been taking its time.

As the front passes through, of course, the temps will drop. Also, the flow will become much more favorable for Telluride. The winds will pick up as the front passes. We may get some additional briefly heavy snow in the southern half of the forecast area as it moves through. Telluride and the areas favoring northwest flow will hold on to the snowy conditions the longest today. However, things could keep going for a while at Wolf Creek, they will hold on to the southwest flow the longest.

There is still some instability in the atmosphere, so I would not be surprised to see some “squally” conditions at least through the morning. I don’t anticipate too many “left-overs” for the southern and central portions of the forecast area, but we’ll see. There is one little shortwave trough extending out of the system that I have my eyes on.

The best guess from the models for the frontal passage is between 8 am and 11 am. We’ll see.

I look forward to your snow reports. I will share them all in my next update later today. Thanks for following and supporting the site!

    2 miles west of Mancos it is 27 degrees and the wind is blowing. I have 4.5 inches of snow and it is still snowing. It will be hard to get an accurate measurement with the wind blowing later. It is starting to drift already.
