Friday Morning Update.....

Brief break and ridge between systems this morning causing fog. Temps have risen a little up to 40 in town. Snow levels are up above 7000 ft. Low off the coast will steer some waves of moisture up the Sierra from the south later today into Saturday morning. Snow levels overnight will be around 7000 ft. for the heaviest precip and then fall to 6000 ft. tomorrow morning. Over a foot is possible above 8000 ft. with up to a half foot above 7000 ft. Left over snow showers during the day tomorrow could accumulate a few inches all the way to lake level, with temps in the low-mid 30's.

Models now showing final system coming down more over land than water for Sunday. This is a cold storm but the over land movement will lower snowfall totals. Still should see some decent snows of up to foot on the mountain and half foot in Town with temps only in the 20's. 12z models have a wave of energy diving in behind the cold front on Monday which would sustain snow showers possibly into Tuesday. The track of this storm is critical so we will have to just keep monitoring it. The duration of snow showers may be what piles up with this storm. This set-up is similar to the Dec.16th storm where the snow showers after the cold front kept piling up.

Could be 10 days of ridging before retrogression and more storms the first week of Feb., so hopefully we get some good snow by Tuesday. BA

Looks like we need to pray to the snow gods.

hr 54 6z nam. Looks like low is a tad more off shore and there is much more of an on-shore flow of moisture comapred to hr 60 of previous run. Trending favorably on this model.

What type of snow are we looking at? I was up at Northstar yesterday and it was very wet and heavy. Too heavy to be enjoyable for me.

we need the heavy snow though to start. Reason bases are so thin is the powdery snows we got in dec. had no water content so they compacted and were easily scraped off the trails by the thousands of skiers. I'll take heavy wet to start, then powder on top.
