Wow! Temps really warmed up today….74 in town.   That may not seem like much, however, the spread was only 6 degrees from the Mammoth AP vs 10 yesterday.   We have lost a lot of the cool air associated with the trof as it is gone.   Expect highs to climb now into the upper 70s this week. The warmest of the Summer so far.  Isolated thunderstorms of the summer time verity are possible beginning tomorrow over the Mono County convergence zone, mainly east of Highway 395. The next trof will bring cooling by the Saturday or Sunday with gusty west winds, especially Sunday!  Critical Fire Weather possible…


Longer Range:


Still Waiting for the Monsoon….

Looking at both the GFS and ECMWF, the is the chance for some southerly flow developing next week.  It mainly affects the Southern Sierra, but it may get up here for a few days for some TSRW action.


More Later….


After a beautiful Holiday and Weekend, toughing at 500MB has extended southward again bringing high clouds and causing about 6 degree of cooling to Mammoth Lakes on Sunday.  I expect this Trof to linger into Monday with it lifting out to the ENE Tuesday AM.  There after, we warm up again into the low to possibility mid 70s.  74 is the normal high for this time of the year so we have a way to go to get there. So far, we are experiencing a much cooler than normal Summer.

Looking at the PWATs over the next week and two….Our air-mass stays pretty dry for the foreseeable future. However there will be periods of weak convergence like on Wednesday and again Friday over Mono County. This means that there could be a few isolated heat and convergence related  thunderstorms, mainly east of Highway 395.


Longer Range:


Long Range 500MB charts from ECMWF has a Easterly displaced Continental High in the mean. This means that the upper flow will have more of a dry SW bias this Summer. It could be one of the driest and breeziest Summers in decades for Mammoth Lakes.

Note; if this pattern should continue into the fall, that would increase the odds for early season snowfall…..
