Highs will be in the 50's again today on the mountain & near 60 at lake level before a cold front moves through tonight. The colder air moving through may spark off some thunderstorms. At most these storms would produce a quick burst of rain, or snow up high.

Tomorrow highs will drop about 10 degrees with highs in the 40's on the mountain and 50's at lake level. As the ridge builds off the West coast another cold front with a dry storm is going to drop down over Nevada. This may have a better shot at sparking off some thunderstorms tomorrow afternoon. Snow levels will be a little lower so a quick burst could put down a dusting.

Going into the weekend highs go back into the 50's on the mountains and near 60 at lake level with sun. The ridge is going to extend North all the way up the West coast of Canada. What we have been hoping for is that the Southern jet stream would still be strong enough to push under this ridge into CA. This becomes harder later in the season. Models over the past 2 days have become pretty consistent with the storms getting ripped apart out in the Pacific and not making it under the ridge.

What will happen is another cold front will mover through Monday night with only a dusting and lower temps back into the 40's by Tuesday. By the middle of next week the a new flatter ridge develops in the Pacific allowing storms to start hitting the Pacific NW. The question is going to be how flat is the ridge and how far out in the ocean does it setup. The difference will be how far South the storms can come. Right now it looks as if a couple of storms impact Northern CA the end of next week into the weekend, but how strong they are is the question. We will need a few more storms by the beginning of April to replenish the snowpack......BA
