December 14th – @ 8 AM – Mammoth Weather 5-Day Forecast: A ridge of high pressure will continue to be the main player in Mammoth Weather into Saturday. The next 3 days on the hill should be very nice with warm mid-day temperatures and lighter winds.

The ridge starts to get pushed out of the area on Sunday as the next cut-off low starts affecting the weather in the area. On Sunday you can expect to see increasing clouds and winds.

By Sunday evening the COL is forecast to push in some high-elevation snow showers in the 8000-9000 elevation range. As the cut-off low gets closer snow levels look to be in the 7500 to 8000 foot range on Monday.

As this is a cut-off low the track will waver a bit over the next few days making the snowfall forecast a low-confidence one. The ECMWF has 1-4 inches while the GFS has 10-16 inches of snowfall.

Right now Snowman is going with the drier forecast ECMWF, as patterns tend to repeat themselves. Hopefully, the wetter solution is what we see on all the models over the weekend.

As for Snowmaking Operations, the system will be able to run nightly during the night and into the morning hours right through the weekend.
