The low-pressure system and associated cold front are inching closer. Moisture should be on the increase by this afternoon. By this evening heavy rain and snow showers will move into the area. Widespread showers and snow showers will stick around in the morning. Showers should develop later in the day and linger on and off on Sunday.
Here is the latest radar. Notice that very heavy rain extending from St George, Utah all of the way back into SE California. That will move into the area tonight.
The worst time to travel over the passes will be between 9 pm tonight and 11 am tomorrow morning.
Winter Weather Advisories have been issued above 9,000 feet for the 550 passes and over to Telluride. The NWS is calling for 6 to 12 inches of snow (before melting) by Monday morning. The latest models show Red Mountain Pass and Wolf Creek Pass may see more than that, call it 12 to 18 inches.
This will be a great boost of precipitation for most areas. Here are some of the latest model runs showing the total liquid precipitation through Monday morning.

For my money, I trust the high-resolution NBM model in this circumstance for the most likely totals.
