Sunday Snow

Noon

The Euro model overnight and again this morning lowered the snow amounts expected with the upcoming storm. This morning the HiRes model has generally raised its expectations with some spikey high elevation totals.

When that happens this close to a storm’s arrival it is not a real confidence booster for forecasters. Balancing the totals is usually a remedy.

Morning Hi-Res model totals

The NWS is staying on the higher side of totals as you can see in the latest advisory.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A WINTER WEATHER ADVISORY FOR SNOW MEANS PERIODS OF SNOW WILL
CAUSE PRIMARILY TRAVEL DIFFICULTIES. EXPECT SNOW COVERED ROADS

I would go with 1-3 inches below 7,000 feet with 2-5 inches for the mid elevations up to 8,000 feet. 4-8″ up to 9,500 feet. There could be some double totals for Telluride, Red Mountain, Silverton areas as well as elevations above 9,500 feet in La Plata, Archuleta, Hinsdale, San Juan, Ouray, and San Miguel Counties.

I am keeping an eye on this one, don’t get caught off guard, there are a lot of components that swing this from a small storm to a bigger storm pretty quickly. I will post in the morning before 9 am.

Stay tuned
