The next in a series of storm systems will move into the area this evening.

With this system, snowfall ratios will be around 8-1 (meaning 8 inches of snow will melt down to about 1 inch of water).

A second storm will be moving in very early on Thursday, with more moderate to heavy snowfall and possibly an additional couple of feet of snow up on Mammoth Mountain. 

The forecast for the upcoming weekend is looking sweet, with clearing skies and bluebird skies.

If you’re out on the hill today, expect increasing clouds and winds during the day. Midday temperatures will be in the upper 30s to lower 40s from Main Lodge down to Canyon Lodge. Over the Mid and Upper Mountain (9500 to 11,000 feet), midday temperatures will be in the low to mid-30s.

On Tuesday, expect snowfall moderate to heavy at times above the 8000-foot level. Lower elevations will see light to moderate snowfall at times.  

From Main Lodge down to Canyon Lodge, midday temperatures will be in the mid-30s. Over the Mid and Upper Mountain (9500 to 11,000 feet), midday temperatures will be in the low to mid-30s.
