94 inches of snow in 4 days at Mammoth, 111 in 5 days at the Sierra Snow Lab. It's the third biggest 5 day storm there ever.

Today in 2015 we were around -10. I'm currently at 67 and the temp was around 60 at 3 am before the huge wind storm. We are capable of a big range of temps in mid February.

Mammoth latest webcam snap shot. This is just an incredible storm for them. When they are getting blitzed, we are having extremely warm weather as a rule. The cold shot we will have for a couple of days Sunday-Tuesday is unusual for us when they are getting hammered. (They have another 3-5 feet event predicted Tuesday and Wednesday) The PNA is negative to maybe neutral, near record cold in Alaska is possible, and the AO/NAO are opposite of where we need them. It will be hard to turn that around enough to have many winter chances for non-elevated areas before the season is essentially over in mid-March. We may see flakes in the air, but impactful snow for most areas is likely done until next late November or December. All in all the winter was decent here for frozen, but could have been much better with the two cold periods we got. The Ohio Valley, and Northeast cashed in this winter. The Rockies struggled mightily but winter ends there in May, so all hope isn't lost for them.

A hail mary shot in elevated Eastern areas this weekend. Severe thread may have some activity. Otherwise, spring-like weather as we close February and begin March.

One of the other channels I watch on youtube who does plowing and snow blowing on Mammoth Mountain got had gotten 90 inches at his location as of Wednesday. He got 30 inches in 8 hours Tuesday night.

A friends daughter went to Tahoe yesterday for a ski trip. It's apparently been awful so far. They couldn't reach their original air bnb, so got another, while working that out, their rental car got buried by a snow plow to the point they had to walk through a bilzzard to their new location. She said it has snowed almost 3 feet since they got there.

It's still just a rampaging blizzard at Mammoth today. Today was supposed to be a light snow day, with only 9 inches on the mountain. They are probably close to 70 inches at this point with 2 or so more feet coming tomorrow.

I believe the UKIE is very inland and too warm for us.

Probably the wildest thing you'll ever see. This is an SPS that's also covering the Winter Storm Warning area near Mammoth. "If outdoors, consider seeking shelter inside a building. Conditions are favorable for the development of weak, brief funnel clouds. This type of funnel cloud is harmless, but on rare occasions they can briefly touch down, producing wind gusts over 50 mph. If a funnel cloud is spotted move indoors and report your sighting to the National Weather Service. These storms may intensify, so be certain to monitor local radio stations and available television stations for additional information and possible warnings from the National Weather Service." The forecast attached to that, this is at 9000-10000 feet. "Tonight: Snow showers before 1am, then snow, mainly after 1am. Some thunder is also possible. Low around 5. Wind chill values as low as -16. Windy, with a west southwest wind around 30 mph, with gusts as high as 40 mph. Chance of precipitation is 100%. Total nighttime snow accumulation of 37 to 43 inches possible."

Life in the Eastern Sierra.

The guy who lives there around 9k feet, that puts videos out, got 12 inches Monday in the pre-event. He's also the one who called 8 inches a dusting. He said his forecast was for 10 feet by Thursday.

They get thundersnow multiple times each winter. It's hens teeth in the East but more common in the high mountain west. It's just a different world, there, particularly in Mammoth. I watched a video about it and the founder of the resort, studied all the available public mountain areas and found basically what he saw as the absolute perfect location for natural snow in the country. The only place that gets more snow is national park areas in the Pac NW in Washington. Mammoth had 950 inches a couple years ago. The world record is 1140 inches in a year.

Mammoth is up to 45 inches today on the mountain and 31 in town. This is the hourly forecast from 7est/4pst until 4am est/1am pst. Yes, that is a 4 inch per hour rate predicted at 6pm pst, and multiple hours at 3 inches per hour. They are supposed to get 20+ more tonight, 9-12 tomorrow, 18-20 on Thursday.

The Mammoth webcam right now is the hardest wind driven snow I've ever seen. The visibility is zero essentially.

There was 14.5 inches here on March 2nd, 1942. We ended up with almost 80 inches here in the winter of 1959-60. 3 inches in December after a very warm month with the snow falling Dec 30th and 31st, 10 inches in January, 25 in February and 39 in March.
