Its interesting to note that the average high temperature for Mammoth now is 65 degrees and will move climatically up into the low 70s by Father’s Day. Our Last freeze is usually Fathers Day.  Over the next 5 days the MJO will be sailing through Phases 7/8 or out over the Western Pacific with borderline moderate AR for far Northern CA on the coast. This is usually associated with lots of high and mid level subtropical moistures at this time of year. (note; in the winter, this can often mean stronger AR episode’s) This weekend’s weather will be no exception with a little cooler weather, breezy conditions and lots of cloudiness, and a chance of showers Saturday night and Sunday.  The Dweebs see more transitory migrating weather systems, while keeping the upper jet to our north.  Not much cooling from these systems is expected as compared to the one that affected the Central Sierra over the Holiday weekend, but wind yes!

Looking at the ECMWF model, for week two, it brings in quite the heat wave to the far west around the 10th. The GFS on the other hand has good rising 500mb Heights earlier week 2.   This tells the Dweebs that next week could get pretty warm at some point with Bishop reaching up to 100 for the first time this year, next week. With all that said, it is unlikely to last as one more significant cool down is probably in the cards before we head into Summer.

 

Local Weather beginning with today will offer light breezes in the afternoon today with a more pronounced Zephyr Wednesday afternoon and evening and possibly Thursday. It will be sensibly warmer tomorrow Wednesday and Thursday as low 70s are expected, then cooling to the low to mid 60s by Saturday with lots of high clouds and yes…Wind!

 

The following week looks a lot warmer with more Summer like weather….

 

ENSO:

The CFS continues its trend in ending La Nina by the end of the year. The new updated IRI will be released on the 19th of June,  It will be interesting to see how all the other models chime in on ENSO.  The Dweebs would like to see La Nina gone and ENSO neutral conditions develop in December.  I think that would be encouraging for more water for California. Next Winter!
