11-2-2020 Snowman Weather Update

Monday 11-2-2020 @ 3:17 PM – We have a weather pattern change coming up at the end of the week, a deep low-pressure system will drop into California. This system will be an inside slider type system that has limited moisture with it.

Expect much colder weather along with moderate to strong winds and some snow showers over the weekend and beyond.

Snowfall amounts are still unclear at this time, but we could see several inches of snowfall into early next week. Just looked at the EU ensembles and it had some areas around Mammoth Mountain with near a foot possible by the middle of next week. (see image below)

The best news with this change in the weather is the Snowmaking Crews are going to get into some serious non-stop action right up to the opener. Been a long time since I have seen a nice cold wave like this for the early to mid-November time period.

For the next few days expect highs on Mammoth Mountain in the 50s with lows in the 30s, in Mammoth Lakes highs will be in the 60s with lows in the 30s. Down in Bishop where they still have peaking Fall colors, it will be in the 70s with lows at night in the 30s to low 40s.

Winds will be light at 5-15 MPH out of the Southwest starting on Tuesday for the Mammoth Lakes area, which will bring some haze and possible smoke at times back into the area.

Below you can take a look at our weather pattern change on both the GFS ensembles and the ECMWF ensembles out to 10 days. Confidence is high now in getting cold air in here that lasts out 10 days. We need these systems to get offshore before they come in to get moderate to heavy amounts of snow.

Snowmaking Forecast: The pattern that is setting up is going to be very cold for 24 / 7 productive snowmaking for several days and then 12-18 hour runs look likely into the middle of November. It will be fun to watch how much snow they can make over the next couple of weeks. The snowmaking system should be firing up some time on Friday Night. Below are the early morning temperature charts for Saturday and Sunday mornings.
