Jesse Posted February 28, 2018 Report Share Posted February 28, 2018 Not sure if this was posted yet... but here is total snow from 12Z ECMWF for Thursday afternoon through Sunday afternoon: Seeing another dusting down here would be fun.

MossMan Posted February 28, 2018 Report Share Posted February 28, 2018 12z still has the snow there. Not often you see a pocket of snow over the ocean south of the low. Yeah it’s pretty rare to see that! Anyone have a large boat that I can borrow? 1 Quote Elevation 580’ Location a few miles east of I-5 on the Snohomish Co side of the Snohomish/Skagit border.

Front Ranger Posted February 28, 2018 Report Share Posted February 28, 2018 We are going to go from no snow all winter, straight into a Blizzard warning. Blizzard warning's are pretty rare for Tahoe. We had one last year and then one back in 2008. Crazy. I see that Reno has had about the same amount of snow as South Lake Tahoe this winter. I'm sure that will change after this storm.

Front Ranger Posted February 28, 2018 Report Share Posted February 28, 2018 I am at lake level so 6300'. My area does pretty well in these cold storms so I wouldn't be surprised to see 40" by the time it is over on Saturday. You said you average around 150"/year? I'm about 850' lower elevation than you, roughly the same latitude, and average about 70"/year. Winters are too dry here! Quote A forum for the end of the world.

AlTahoe Posted February 28, 2018 Report Share Posted February 28, 2018 You said you average around 150"/year? I'm about 850' lower elevation than you, roughly the same latitude, and average about 70"/year. Winters are too dry here! Tahoe city averages 190" a year on the North shore. We average about 150" on the south end of the lake. We have huge variability between years though. Our lowest (2014 - 2015) only brought 12"whereas our biggest years like 1952, 1969 can bring over 500" to lake level. I think the record is 532" in 1952. In 2010 - 2011 I recorded 388" at my house.

bainbridgekid Posted February 28, 2018 Report Share Posted February 28, 2018 Seattle NWS take on the Friday morning potential: Heights will steadily fall at 500 mb as an upper low driftssoutheastward out of the Pacific. Rain showers will continue andsnow levels will drop to between 1,000-2,000 ft by Thursday ascolder air aloft moves in. The weather may get more interesting byFriday morning around 12z as the column cools even further. Aband of precip moving in may take advantage of wet bulbing effectsto allow some snow to mix in with the rain 12-15Z Friday morning.Snow levels look to fall down to around 500 ft. Temps will bemarginal which would favor limited accumulation. Then the modelsfeature warming in the low levels after 15Z, so it would be a verynarrow window that would limit impacts, but given the rush hourcommute time frame, will monitor this closely today. The upperlow will weaken and drift inland and the heights rise by Saturdayso a warming and slow drying trend is expected over the weekend,as rain turns more showery and diminishes in coverage. 2 Quote Everett Snowfall (510 feet elevation) Snow since February 2019: 91" 2023-24: 6" 2022-23: 17.5" 2021-22: 17.75" 2020-21: 14.5” 2019-20: 10.5" 2018-19: 24.75" Link to comment Share on other sites More sharing options...
