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.
