A Little Break, But It's Not Over Yet..........

Storm heading across the Pacific is now cut-off from the jetstream & will screw with our chances for snow as it spins out in the Central Pacific for a week. Basically the affect of the storm is that it will bump the ridge to the North, & the ridge will bump the storm track to the North. If this hadn't happened we were on track for a stormy week next week.

Slight retrogression of the ridge & the storm back towards the Central Pacific on Saturday may allow for a storm hitting the Pac NW to come far enough South to bring snow to Tahoe Sat. night. Models in a little bit of disagreement on how far South the storm comes, but it Doesn't look like much if we get any, just some light snow showers.

Starting Monday the cut-off storm & ridge shift back slightly East & push the storm track just to our North. The Pac NW & into far Northern CA will get hammered with storms thru next week, but they will just miss us. We will be stuck in the sun with temps in the 40's on the mtn., 50's in town. That is ok since we have plenty of snow on the ground.

As the cut-off storm over Hawaii finally gets pulled Northward by storms to it's North, the ridge will be able to retrograde Westward towards the end of the week. This could lead to some storms for next weekend.

After that it looks like a typical pattern of ridges building in for a few days then retrograding & allowing cold storms to dive in. I still think we can get 1 or 2 good storms before the end of the month. Like December, when we are getting close to a change in the seasons the models are not very accurate in the long-term. Will have rely on good old fashioned studying of the global patterns. Right now they suggest that Northern CA still has the chance at some decent precipitation the end of March into April. BA
