Tuesday Evening:

Moisture bands are holding together well as they move across the sierra. Good upslope along with the approaching cold front should allow more showers to drift over the crest and into Mammoth over night. Top of Mammoth Mt is still above freezing at 36 degrees at the moment. Some cooling will give the chance of a dusting over night over the upper elevations…

Another VT max is seen off shore and once again the models are painting it dry like this one over Mammoth.  Best to keep the chance of showers in the forecast for Wednesday…


Tuesday Afternoon: 3:30PM

Latest Sat Loop shows an active cold front making its way through Northern Ca. The bottom of the front will miss much of Mono County as it swings east to the north of us.  Never the less, the west side of the sierra will likely pick some light amounts of precip. Isolates showers are in the forecast for Mammoth Lakes tonight into early Wednesday AM. If there is any moisture left by Sunrise, there may be a few snow showers…..but that is a big if!   The freezing level is forecasted to be about 10K between 12z and 18Z….so out side of the crest….Nothing for the TOML. .  For Southern Mono County, it looks like mainly cooling and wind.  After this late Summer trof lifts out tomorrow, 500mb heights will begin rising by Wednesday night…with a warming trend following into the weekend.

Some great weather expected for this weekend with highs returning to the low 70s.


Monday Evening:

Mother nature coming to the rescue with cooler temps light showers and higher humidity. As a result, fire fighters are getting the upper hand on the western slope sierra fires. The rough fire is now 40% contained…Putting out less smoke.

A Gulf of AK upper trof will swing through Wednesday AM bringing winds and much cooler temperatures. There is even the chance of some snow showers.  The freezing level is 9900 Wednesday, so no accumulations expected…


The Remains of TS Linda are currently moving though Central CA and climbing the west side of the sierra. Showers and thunderstorms could begin at almost any time now,  with the main impulse and precip targeted for Southern Mono County West.  New HRRR shows QPF in the . 5 to . 65 range.

So get ready for some rain.. Great news for the forest!   Next upstream system to swing through Mono County Tuesday night/Wednesday AM….with upper jet axis close by early Wednesday AM.  This will bring a chance of rain showers Tuesday afternoon and night, then Tuesday night into Wednesday Am.  It could be quite breezy late Tuesday night into Wednesday AM. Daytime highs todays will be in the upper 50s cooling to the lower 50s by Wednesday. It will be quite breezy early Wednesday AM.  Lows at night tonight dipping into the mid 40s then upper 30th Tuesday night, then upper 20s by early Thursday morning…. A light freeze is expected….



Milder weather returning this weekend with highs back into the low to mid 70s….

El Nino is alive, strong and well……
