Tuesday Afternoon Update

Looking at the total precip runs it looks as if not much has changed in the last 24 hours. Behind the scenes, a closer look at a different model parameter reveals some warmer air working in that could raise snow levels to around the 7,000 foot level on Thursday afternoon. That is good news for people with light travel at the lower elevations. This could also flip back to all snow on Thursday in future model runs. In any event, tomorrow I will also add the snow output data. The only affect this will have on the mid and higher elevations is lower snow ratios, 12-15 to 1 at Purgatory, Telluride and Wolf Creek with 10-12 to 1 for the mid-elevations.  Friday is still the big day, and cooler air will accompany the heavier snow.

Again, I hope that this trend doesn’t continue, but you will probably start seeing  RSM (rain-snow mix) language for the “lower valleys”, as they call them, in the upcoming Watches and Warnings.

At this point, the Euro is still the most conservative (although it still shows 30+ inches of snow for Purgatory). So I will start with the Euro and end up with the Canadian which I have the least amount of faith in.

Tomorrow I will go into greater detail since the snow will start late Wednesday and early Thursday morning. If the NWS updated their Winter Storm Watch this afternoon, I will post comments late afternoon.
