Wednesday’s storm was not actually a bust….but Dug much further south then earlier predicated. As a result, the Southern Sierra did the best precip wise with amounts close to a foot in some upper elevation areas. Aspendale received 8 to 9 inches! Over all, Mammoth got 1 to 3 inches which was at the low end of the forecast.
Lots of frost this morning on local roofs. The Aspens is some areas have been hit hard and have turned black while other areas are having a nice display. If you’re coming up for Fall colors don’t wait any longer….
October so far has verified colder than the climate forecast models earlier predicted. High temps now in the 50s with lows in the 20s.
Forecast and discussion:
Both EC and GFS show the storm system that came through here Wednesday over the northern plains states now with a dry NW flow aloft. The upstream ridge at 500mb is expected to amplify out at about 140west which will allow a short wave to dig into the Great Basin and bring some wind and cooling to our region beginning Saturday night into Sunday. Saturday night will be breezy while Sunday will be some 5 to 7 degrees cooler. There will be some north wind as well for the Owens Valley Sunday and the valley will cool to the 60s.
Thereafter for the week of the 15th; The short wave upper ridge off shore weakens and it progresses near the Pacific Northwest coast Thursday. So at this time, next Wednesday and especially Thursday of next week look to be the warmest days with mid 70s in Bishop….plan your “Tee Times” accordingly.
By Friday….That upper ridge then collapses under the weight of a passing short wave Saturday into Sunday the 20th…..A few ensemble members split off some short wave energy and take it over the Sierra Saturday night the 19th into Sunday the 20th with some snow showers possible. What ever happens….. it will not be a big deal…..
So….As we move past the weekend of the 20th…..Retrogression takes place in a pattern that apparently is going into transition for that following week beginning the 21st…….
ALL PASS LINE BETS OFF FOR THAT FOLLOWING WEEK……………
