After a storm that dumped about a foot on Mammoth Over the Weekend….the weather will take a bit of a break as the series of short waves track mainly to our north this week. In the 5 day 500mb means, there is a height anomaly that is situated over the desert south west that will provide more gradient and thus more wind for the upcoming Thursday system. In the meantime, ridging at 500mb is building in and a decrease in upper elevation winds are expected today into tonight. Temps will be warmer today into Thursday. The next cold front may not even make it this far south Thursday pm. However winds up at 700mb will still howl. Expect winds over the upper elevations Thursday afternoon to be strong.
The next in a series of short waves will effect the sierra over the weekend. The upper jet with the system is not all that strong. Nevertheless there could still be some showers but any accumulation will be light of any. The next significant chance of a little powder will be next Monday as the right rear entry region of the upper jet swings through the Central Sierra.
The CPC currently has a weak MJO moving quickly through phase space 7/8. Odds favor between normal to warmer then normal temps. Also below normal precip for the Central Sierra. This may be relevant to this weeks 1 weather currently forecasted by global models.
The weak MJO is expected to move quickly eastward into phase space 1 where the odds increase for precip for the Central Sierra for the month of March. This would be during the period beginning about the 15th through the 21st and especially beyond the 21st.
Global Models are trending in that direction……
