Update on Advisory and initial thoughts on accumulations.

I was hoping to see a little spike in the accumulations from the models but that has not yet happened. I still prefer to handle this as two storms, but the lull between does seem to be narrowing, with the second storm coming in Friday night according to models. All of the factors still could change between now and then.  Hope for that delay if you want snow and live below 7,200 feet because that looks like it will be the maximum level for rain before snow tomorrow late afternoon. The heaviest snow will fall everywhere after dark but it is not going to last long. Again things could change, we will see. For now, I am looking at 0-2 inches for elevations below 7,200 feet with 2-5 generally everywhere else. The models have been highlighting the DWest to Hesperus and up to Mayday for that 2-5 with less on the eastern portion of the county. Just because it says that now does not mean it won’t change overnight. Purgatory looks in the 2-5 inch category as well for the first storm. Telluride should do better with the second storm. Wolf Creek could be in the 4-7 inch range for the first. I will post throughout the day tomorrow so make sure to check back.
