“atmospheric river”

By ccrossen | November 27, 2012

Big weather event about to unfold for Northern California - a major subtropical moisture plume is setup to unleash on us. Forecast is calling for a lot of liquid, and some snow way up high. Snow levels will be fluctuating greatly over the next five days. NWS is calling for 12-20 inches of rain in the Coastal Mountains and up to 8 inches of water for the Sierra. That is a significant amount of liquid. We may get some snow Wds/Wds evening, but then we get a very warm plume come in Friday-Sunday, with heavy rain at times. Snow line will be 7,500′, but then potentially rising to 8,000-11,000′ Sunday during the day. Sunday evening into Monday we get much relatively lower temps and the snow line around 6,000′, so maybe 1-2 feet up higher. We’ll have to see how it all plays out because there is a lot of action and a lot of liquid and variables. Hang on tight and break out the rain gear.

Next system on tap looks on target for mid-next week, and that too looks like a warm one.
