The Word
11/10/09 4pm
The word this afternoon is trending a bit drier, but all in all no surprises in the afternoon forecast package for tomorrow. Winds have started to pick up this afternoon, and the high cloud cover has been persistent all day. High temps this afternoon are around 50F.
Looking at tomorrow and Thursday's storm, a Winter Weather Advisory has been hoisted by the Sacto NWS for the Western Slopes of the Northern Sierra Nevada. For Tahoe, precip should start banking up against the crest in the afternoon and dropping into the basin by evening. Snow levels will start out around 7k+/- and drop quickly with frontal passage. Cold front passage is approximated to be around 1am Thursday morning, so this will essentially be the *height* of the storm. How high? About high enough to drop 3-6" along the TSC and 2"+/- around Truckee. So nothing big in the accumulation department. Temps will drop pretty good behind the front as Thursday's highs will be ~40F in Truckee and upper 20s @8k. Winds will be strong during this event, SW 15-25, G40+ in town and gusts exceeding 75mph along the ridges in the afternoon, decreasing substantially after FROPA. Snow showers will linger on Thursday, mostly along the crest. Morning lows Friday/Sat/Sun will be in the mid teens with afternoon highs in the 40s.
This storm is definitely on the cold side for Tahoe in mid November, so the snow will be light and powdery.
Not so good news for the potential storm for Friday/ Saturday. Models are making it all but non existent, so we will see if they come back around in the next 36hrs or so. Right now the consensus is rising heights and dry conditions Sat->Tuesday.
The first significant snow producer for Tahoe might be next Wednesday.
