Life is good on the Dark Side of the Sun………….

Today’s a special day…  It’s the shortest day of the year in the Northern Hemispheric. The suns rays are at their greatest angle away from us…Our day-light is at its dimest…..It feels like were on the Dark Side of the Sun…..  However, its a very special night tonight as the Grand Conjuction of both Saturn and Jupiter will cause both planets to appear as one. Catch it,  when skies darken tonight, in the southwest above Mammoth Pass….

An approaching inside slider has brought breezy conditions to Mammoth Lakes this afternoon. It will turn colder the next couple of days, however, the system is very progressive and its quick departure will not likely allow any precipitation to the high county. A quick dump of cold air is likley, followed by a short wave ridge to cap it off…..

Further out in the pacific is a small wave that has become pinched off, will spread high clouds over our area beginning later Wednesday into Christmas Eve. Precipitation is not expected from this weak system. Further out time wise, an approaching upper jet will act to consolidate the upper flow over Central and Northern CA by Christmas Day Eve.  The jet will carry a lot of moisture with it. However, threre will not be any cold air advection as the upper jet is to the north of us. So littel in the way of any dynamics. Preliminary EST Snowfall amounts look to be in the light range with some 3 to 6 inches.  Will fine tune over the next few days. Precip looks to fall primarially between Friday night into Saturday with the snow level aroud 6000 to 7000 feet. The Owens Valley looks to be shadowed out from this system.

The following system looks more dynamic for later Sunday into Monday….Potentially, that may be a better snowfall producing weather maker.  The only caveat is that the system appears to be splitting so more time is needed to determine its precip potential.

Beautiful Weekend shaping up with above normal temperatures at resort levels and Pogonip fog in the valleys…..Cold inside slider to bring chilly weather Tuesday and Wednesday with as possible dusting Tuesday……Snowfall chances increase Christmas weekend….

It is a spectacular weekend here in the high country with highs in the upper 40s to low 50s….High pressure this weekend will give way to a cold inside slider Tuesday. High temps will cool a good 15 degrees Tuesday with a dusting of light snow expected.   The weather will warm up Wednesday into Christmas Day with fair weather.

A strong upper jet will be moving off the Asian continent this weekend headed for the west coast.  A weak weather system following the inside slider will become cut off from the westerlies mid week and may be picked up by the on-coming upper jet Christmas Day Eve. Although this system is weak, it may spread some showers into Southern CA Christmas Day Eve and even up through the Owens Valley. The upper jet that’s the kicker, will approach Central and Northern CA the following Saturday with a small Atmospheric River.  The longer range shows another system for the 27th and 28th that may bring additional snowfall to the Central and Northern Sierra…  Stay tuned, it appears that the pattern will becoming more active beginning the weekend following Christmas.

Storm Total Approaching 12 inches on Mammoth Mt……5 to 8 in town….Weather goes dry through Christmas….Pogonip Fogs Return this weekend over Lower Elevation Eastern Sierra Lake Basins




December 18th

Storm Total 12 to 15 inches…

The Forecast is now dry through Christmas day.   Temperature inversions will allow Pogonip fogs to develop over nearby lakes from time to time when east winds are not breezing… High temps will move into the 40s this weekend with lows in the teens…..It is a dry 5 to 7 day outlook….

Grand Conjunction of Saturn and Jupiter occurs this Sunday and Monday evening after Sunset when both planets align as one.  Dont miss the best celest. show in nearly 800 years…..  The peak is Monday but you want to see it Sunday eve as you never know if it will be cloudy Monday…

WX discuession:

High pressure builds back over the west coast with light east winds at the surface and NW aloft. Ridge builds in strongly on Sunday with highs in the Owens Valley in the 60s and 45 to 50 in Mammoth by Sunday.  There will be partly cloudy skies Monday night and Tuesday as a weak wave pases through.  Next weather system capable of bringing moderate snowfall will be weekend after Christmas day. That one will have AR moisture. Another systems may give us more snowfall around News Years Eve….


The strong base state of La Nina and it strength, continues to affect the mid latitudes in a negitive way for California by distructivly interfearing with the various modes of tropical variability as they attempt to migrate or propagate eastward over and beyond the dateline….   La Nina will gradually weaken later this Winter and Spring….. Central and Southern CA precipitation should then increase respectivly…. Especially in late February, March and early April….

The Weather front that brought snowfall this morning was over Southern Ca and the upper level trof was moving through Eastern California……
