It appears today Monday will be the warmest day of the new week, then the upper jet pays a visit the the high country Thursday into Friday toward the holiday weekend. This mornings guidence showed an east-west oriented upper jet coming into the CA/OR boarder. A short wave trof is currently pushing into Oregon St. As it does, the Front Right exit region of the upper jet will breeze things up over Northern and Central Ca this afternoon and evening. This is a dry system for most of California.
Beyond today Monday….temperatures will slowly cool as the upper jet to the north becomes more NW/SE oriented. By Thursday AM…the nose of a 130knot upper jet begins to shift south into Central California. As it does…. winds will come up Thursday into Thursday night…Clouds will increase as well and cooling will quicken.
By Friday morning, a cold core upper low swings into CA….then over the Sierra by late morning bringing snow showers to the upper elevations. Showers may continue into the evening with the snow level lowering to about 5-6000 ft Friday night. At this time it does not look to be significant snowfall producer. (A couple of inches max) but temps look some 20 degrees below normal Friday (highs in the low to mid 40s in town) and 30s (upper elevations) with the chance of some light snowfall……………Expect Partly cloudy and gradually warmer weather Saturday, Sunday into Monday……
More on this system later in the week……
First Half of June:
Normal to below normal temps
Normal chances of measurable precipitation
