My friends…

It’s always a beautiful day here in the Eastern Sierra. I’m Noé from eastsideweather.com, here for MammothFM in the Eastern Sierra, coming atcha with your local weather report…

Thursday will be dry. And then, on Friday, a strong but fast cold front comes through the area. The winds currently look very heavy ahead of and during this system. Southwest gusts of 40 to 55 mph are expected along 395 by late Friday morning, and 60 to 80 mph over ridges.

Snow moves in Friday afternoon. Snow levels start around 7,500 feet, fall to about 6,000 feet by Friday evening, and drop even lower, to around 5,000 feet, Saturday morning. The heaviest snow falls Friday from about 4 in the afternoon to about midnight, with snowfall rates of 1 to 2 inches per hour.

As of now, I’m expecting a Friday and Saturday total of about 4 to 8 inches in Mammoth Lakes, 6 to 10 inches at Main Lodge, and 8 to 14 inches on the summit of Mammoth. Travel may be hazardous, and impossible at times depending on conditions, during this storm.

The storm clears out Saturday morning. A colder storm with less moisture is on its heels late Sunday night into Monday. Confidence is currently lower on this one, but it could bring several more inches of snow to lower elevations as well. And another storm is trending likelier for next Wednesday and Thursday as well. Stay tuned!

And now for the weather forecast this weekend:

In Mammoth Lakes and the surrounding areas:

Thursday will be sunny with a high of 56 and light southwest winds, then mostly clear skies Thursday night with a low of 29 and southwest gusts up to 30 mph.

Friday is our storm day. Snow begins after about 10 in the morning, with a high near 44 and strong southwest winds gusting up to 55 mph. Two to four inches could fall during the day.
