Randall Osterhuber has tallied up the official numbers up at the Central Sierra Snow Lab on Donner Summit. Mark McLaughlin at thestormking.com, our local storm historian, has added this season to his records as the 8th snowiest season on record and you can find this data on his site. With 54 feet now the official tally after picking up around 4 feet in the past month, we have pushed past 1982, 1967, 1907, & 1893 to move from #12 to #8. In the past 100 years we are now at #5. We are only a couple feet off 1983 which is the biggest snowfall season in the last 58 years and the record year for many of the ski resorts.

The snow depth on Donner Summit was also measured on June 7th at 94 inches (7.8 feet) deep. The Snow Lab began keeping records in 1946 and the old record for June 7th was 80.4 inches (6.7 feet) deep set in 1967. This is causing some concern for water officials as most of the lakes and reservoirs are full. As summer temps hit pretty quickly over the next couple of weeks all that snow is going to melt into swollen rivers and full lakes. Overall precip for the water year which goes from Oct. 1st – Sept. 30th is at 82 inches. That puts us at #13 on record with just under 4 months left in the water year.

Unlike the last time I posted our snowfall ranking, this time we should be staying put. Spring is here and summer is close behind it. There is still some troughing along the West coast through the weekend which is keeping us a few degrees below average in the 60′s. The ridge will build in even more over the Southwest next week and starting Monday we should finally have average temps for this time of year, up into the 70′s next week. I don’t see any big heat waves in the future right now which is good news for run-off. We should stay warm, sunny, and increasingly warmer as we go through the month and into July.

I have gotten some grief about my posting that May would be warm and dry back in March and April. When I am trying to forecast out a month or more I only have history to go off of or the teleconnection forecasts. In May the teleconnections were right for ridging but the MJO came to life. I wrote off the MJO after it didn’t have much affect on the weather this winter, I think because the La Nina was so strong the cold water along the equator killed it anytime it came into the Pacific. But as the La Nina has become almost neutral this spring the MJO’s affects became a factor again.

As we ended May and started June the teleconnections were right for West Coast troughing again. Now we are headed back towards ridging with no MJO activity, so game over! I know long-range forecast accuracy isn’t always there but at least there is a forecast. One reason I started this blog is that there aren’t any other long-range forecasts out there when you are dying to know when it’s going to dump again. So I’ll keep sticking my neck on the line and hope I continue to be more right than wrong. I think the cold water in the Pacific has been changing the weather patterns over the past few years and throwing a curve to forecasters. I look forward to the challenge!

I will be cutting back posting here in the summer as the weather stays quiet. Stay tuned for posts on the outlook for next winter over the summer. If you like the facebook page you will get a message anytime I post an update. Thank you to all who read my rants as I am always surprised anyone wants to hear me ramble on about the weather everyday. This season there were 63,000 of you that wanted to read my ramblings 455,000 times. Thank You…..BA
