Unsettled conditions to return
Lake Tahoe Area Weather and Snowpack Information
2/18/10 8:53pm
After a few days of spring, and a dry spell that has lasted way too long, unsettled conditions will return to Tahoe tomorrow. The strong ridge overhead is getting pinched North as energy retrogrades West out of Ida-ho (to Ta-hoe) while low pressure makes its way onshore over central/ southern CA. Models are still all over the place, but I do like what the GFS is throwin out. The GFS is very bullish in bringing Pacific energy onshore into CA, with a more Northerly jet streak, every other day through the next week+.
For tomorrow night into Saturday, the storm that once was looks like it will take a jog into SoCal, leaving Tahoe on the periphery. Snowfall totals will be measured in inches along the TSC. Sunday's storm looks like it might be a producer. Problem is, a forecast outside 24hrs right now runs the risk of being completely off. I want to believe that we will see 1-2' of new snow along the TSC by Monday night.
Temps will fall back into normalcy and snow levels will start out 6500-7000' Friday, dropping to 4500' on Sunday. Expect gusty SW winds by tomorrow night along the ridges.
Winter returns and might stay around for a bit. Spring is a ways off. Remember, the jet stream will shift back North as we get later into winter and if the storms are there, the hose will be on big blue. Wax em up! It's going to get good again.
