little Break.............BIG Storm

Beautiful sunny weather with temps in the 40's thru Sat. Perfect weather for the Dew Tour. Don't forget your sunscreen.

Big trough is being dug-out over the East which is holding the ridge in place over the Rockies and putting a jam in the progression of storms for a few days. BIG storm off the coast will sit and draw moisture from the tropics for the next few days. The longer it sits there the more moisture and energy that will be pumped into it. As soon as the trough over the East kicks out the progression of storms can once again begin. This should happen sometime on Sunday with the precip arriving in Tahoe sometime later on Sunday. This will be huge amount of moisture that will fall within a 48 hour period. With the flow coming from the South out of the Subtropics, the snow levels will start around 7000ft. with this system and then start to fall. The mtn. could be in for several feet of Sierra Cement.

Everyone is worried about some rain in town or at the bottom of the mtn. Don't worry the snow level will crash by Monday night and lots of cold storms look to be in our future at least thru the first week of March. A little more base building snow won't hurt, especially in April. No change in the extended forecast with models still showing the ridge holding over Hawaii with cold storms hitting the West Coast into the extended.

Since there will be a jam in the weather pattern for a few days I will not be posting againg till possibly Sat. night. I will be up enjoying the Dew Tour and the nice weather before it's time to start shoveling again. BA

Sorry if this going through twice. Having computer issues. I have always been amazed at your ability to make long term forecasts. They've been really awesome all season. You predicted this series of storms over a month ago, which is so amazing. I dare ask you, how late into this year can you guess that we'll still be able to ski up here in North Lake Tahoe?

I can't take credit for the actual scientific research that goes into long range forcasting. I can only take credit for researching the the research done by these meteorologists and then relaying the message in an easy to understand format.

Can't say about how long just yet, all I can say is that looking forward I can't find anything that shows a reason for the storms to stop, only reasons why they should continue thru March. If we can get a big March then obviously we can get a season extension. If the situation changes you know I'll be on it.
