Going to let this post sit for another day so that everyone can absord the huge amounts of snowfall over the past few weeks. I will post again tomorrow on the storm this weekend and the long-range.
Resort Totals page is updated to show the total snowfall amounts in the past 10 days, 15 days, in the month of March, and the season. 8-16 feet on the resorts in the last 10 days of non-stop snow, 11-21 feet in the past 2 weeks, and 13-23 feet in the month of March. Season totals are now being reported at 500-800 inches with just about every resort along the crest over 700 inches now. That is around 156% of the seasonal average.
Reader reports is updated to show the 9 day storm cycle totals through Saturday night as nothing accumulated at lake level on Sunday. Storm totals over the 9 day period of Friday 3/18 to Saturday 3/26 are 4-9 feet around the lake. Although many resorts are measuring their largest or in the top 3 largest snowfalls on record at the summit, the official snowfall from the Central Sierra Snow Lab on Donner Summit as of Friday morning was 531 inches (44.25 ft.) which is in line with 97-98 and puts us in the top 14 winters in the past 100 years. We should have gotten enough snow over the weekend to push us up to the top 12.
It is only March 28th so we are not done yet with snowfall on the mountains this season, but we are done for at least the next 5 days. The ridge is building off the West coast and it will be right over CA by Thursday & Friday. Temps will be chilly still today in the 30′s on the mountains & 40′s at lake level and breezy. As the ridge builds in temps will rise all week with 40′s & 50′s Tuesday/Wednesday and then 50′s & 60′s by Thursday and Friday.
The flow stays fairly progressive over the next couple of weeks, so the ridge moves to our East this weekend. That will allow a storm to move in to our North on Saturday and Sunday. It is looking pretty week right now with only light snowfall above 7000 ft. The biggest change will be windy and colder weather over the weekend with highs only in the 30′s & 40′s.
Long-range models can be pretty unreliable this time of year with the change in the seasons. Teleconnections may be more telling as they are a semi-constant in the chaos of the weather patterns. They favor a ridge along the West coast through next week and the models do show a ridge moving back in the beginning of the week. As we go into the second week of April the teleconnection forecasts show a pattern that would once again favor a retrogression of the ridge and a trough along the West coast.
Enjoy the nice weather during the weekdays these next two weeks as we see sunny skies and nice temps. We have an amazing snowpack to start April. The final March numbers for snowpack and precipitation will be out next week. As we go towards mid-month I think we have a chance at a return to below average temps and some storms. Stay tuned……BA
