Cooler Weather and Quite Breezy Over The Upper Elevations Sunday
Sunday January 9, 2011

Just a quick update this morning…
It’s very breezy over the upper elevations this morning. With the ambient temperatures in the 20s today dress warmly up on O’l Woolly!
Strong upper jet NW-SE Cutting through Nevada today. Dry cold front will slowly make its way through southern Mono County later this afternoon. A wind shift should occur for the Owens Valley tonight and so expect north winds to really pick-up this evening. (15 to 30mph)
Highs in the Town of Mammoth will be a bit higher then forecast as the front has slowed down. As of this writing, the town has probably peaked on temps for the day (33 degrees)…..while night time lows will drop into the single digits. Light breezes are expected for the TOM.
For the coming week…the main storm track will be well into the pacific northwest. For the Central Sierra, expect mostly light to possibly moderate warm advection type (Isentropically lifted) precipitation. So some light snowfall is expected Tuesday and Tuesday night. There will be some chance of light snow throughout most of next week. Snow levels will rise most of the week. High temps will go from the mid 20s Monday to the 30s by Tuesday into Thursday then into the 40s by next weekend. There is still a possibility of a January thaw the following week.
The key to our longer range I believe is whether or not a MJO develops week 2 and modulates the westerlies as the NAO is going to be in the positive mode toward the longer term.
LA NINA is still raging!…….
