The return of troughing along the west coast will bring slightly cooler temperatures this week along with an enhanced Zephyr…The pattern will ensure a dry week for Mammoth Lakes….

Latest update shows an upper off-shore trough will keep our air-mass dry through at least Saturday.   The Southwest flow brings both stability to our atmosphere as well as a drier air-mass. Some cooling will occur by midweek with high temps settling back to the mid 70s from a high of 79 on Sunday. Lows at night that have been in the 50s will cool down to the 40s in the more wind protected areas. The Mono County Zephyr will be enhanced each afternoon and evening hours so that areas of Town like the Mammoth Meadow area will have gusts to at least 30 mph. Other areas of town will have west winds in the 10 to 20 mph range. The SW Monsoon and its air-mass modifying effects has shifted well east of California, not allowing any related precipitation at least through Saturday. This is true for both the Southern and Central Sierra. Some of the global models this morning try to build back westward, the continental high, strong enough to bring a warm up,  along with moisture, and the air-mass modification. Thus will introduce  the slight chance of showers and thunderstorms by early next week.  At the moment, it is only a slight chance, until there is more agreement with in the global models for that following week.

Weather to turn dry again following a wet Thursday…Warmest temps of the Summer Sunday and Monday…..Dry weather to continue through next Friday….Will the Monsoon deliver the final act of the Bluesapalooza?

After a brief encounter with the SW Monsoon, The series of upper trofs moving through the pacific NW will deepen, pushing drier air into the region. As the same time, the Continental High will retrograde westward and become stretched East-West, shunting Monsoon moisture to the south over old Mexico.  The core of the warm air gets centered more over California in the days to come. As a result, instead of the troughing providing cooling, higher heights aloft will create warming instead.  Expect Mammoth to approach 80 degrees by Sunday with little change in temps through Tuesday.  Our Mono County Zephyr will be back early next week providing the usual afternoon and evening winds. The drier air will allow nighttime temps to lower into the 40s……So great sleeping weather ahead!!

The  Bluesapalooza, “Blues and Brews fest” is next weekend. The weather pattern has the Continental High shifting east again by then. As a result, it is possible that Monsoon moisture may make a return by next Saturday or Sunday. Lets hope it’s the end of the week!

The Dweebs will update later this week.


Daytime highs in the upper 70s and low 80s the next 5 days with night time lows cooling to the 40s.   The Mono County Zephyr will pick up in the days ahead into the 15 to 30 MPH range in the breeziest arenas of town…. That is in the afternoon and evening hours…

Southerly flow to provide more showers today and Thursday for Southern Mono County…A drying trend to begin later Friday with a dry and warm Saturday through Tuesday expected….

Although Mammoth Lakes did not pick up any showers on Tuesday, showers and thunderstorms developed from the north, to the east and southeast with ground reports indicating of over an inch of rain over the Rock Creek Lake area as reported by the owners of the resort. Other areas including Tioga, Bodie Hills, Doe Ridge, Mammoth AP and BISHOP AP, indicated light amounts of precipitation ranging from a trace to up to .12 of an inch.  For the next few days, showers and thunder storms are possible in these same areas.   Mammoth so far has been exempt from this precip as early afternoon zephyr winds have sheared and blown most of the cloudiness to the east.


Outlook;   The Rapid refresh model once again is keeping showers out of Mammoth Today. However, there is a Vort Center coming up from the south Thursday afternoon that might aid in providing showers and thunder further west, into Mammoth on Thursday. The Vort center is associated with the Rt Rear entry region of a 50 Knot jet at 250MB.

The weekend outlook is dry with only isolated activity Saturday and dry in all areas Sunday through Tuesday.  The continental upper high shifts west into Southern CA shunting monsoon moisture and upper dynamics south. It will be warm in Mammoth and hot in the deserts.  Highs in Mammoth 75 to 80, lows in the 50s…
