Alaskan blocking pattern still keeping CA unsettled with no end in sight…..light to moderate snow producing systems likely to continue through mid April….

April 5th

Fridays weather system continues to weaken as it lifts to the NE.  Amounts of snowfall will be very light with little accumulation.  Mammoth will have a bit cooler weakend than what was forecasted but certainly milder than past days.  Highs will climb into the low to mid 50 while lows at night in the 20s,  then 30s later in the weekend.

Pattern still favorites unsettled weather with more showers later monday and into following Thursday.  On a bright note, for the fisher folks…Lake Crowley is just beginning to break up.  The Dweebs are expecting the entire lake to be open for the fishing opener later in the month.

it is becoming the Winter that would not end in the high country as a parade of low pressure systems head for the Sierra. Wednesday and Sunday seem to be the nicest days of the week.  The quantitative precipitation outlook shows up to another 15 to 20 inches of snow possibly falling on Mammoth mt this week.

The next WX system is bringing a band of showers to northern CA at the moment. The band will slowly move south into our area later this afternoon.  The snow level will rise to 9000 feet tonight so it will be mostly rain in town.   Cooler air arrives tomorrow morning bringing the possibility of 1 to 3 inches to the town.  Some 4 to 8 inches is possible on Mammoth  Mt.  Next system Thursday then stronger system Friday night into Saturday.

A Spring Storm System will bring heavy snow overnight with showers Wednesday afternoon and Thursday……Skies will clear by Friday with seasonal temperatures expected by weeks end…….No major storms expected the following week…..

The winds have been blowing throughout the high country the past 24 hours with stronger gusts expected today.  Expect increasing cloudiness today with a slight chance of snow this afternoon…..A Winter Storm Warning is in effect, beginning at 1100pm tonight through 1100pm Wednesday night. Snow fall amounts are expected in the 6 to 12 inch range in the Town of Mammoth and between 1 and 2 feet on Mammoth Mt by Thursday morning. Additional amounts are expected, however lighter on Thursday.

The weather pattern across the EPO region still is highlighted by a block. Thus the westerlies are forced to the south  across the central and eastern pacific. Nevertheless, height rises will occur this weekend and early next week for some beautiful weather across California outside of a few instability showers early next week.  There may be a storm on our horizon the following weekend…

Beautiful Weekend in Play with Spring in the Air…..Vernal Equinox arrives early this year as Winter shifts into Spring…Unsettled weather returns Wednesday into the weekend..

March 20th….7:15am

Mammoth Mt reports 7 to 10 inches of snow overnight…..the WX front with this storm is through Mammoth….However there are several VORT centers that will keep the weather showery today through Thursday. There is another 2 to 4  inches over the upper elevation possible through tomorrow.

So the secondary’s will roll in tonight and tomorrow as a couple of vort maxes roll through.  Any one of them could produce 1 to 3 inches as they are convective and may have some thunderstorms with them. Some Isolated amounts may be up to 6 inches in a few areas.  The next system Friday night may Bring some 5 to 7 inches over the crest…Friday night into a Saturday morning……MORE LATER….



March 18th 9:10AM

Spring will roar in like a lion this year as several light to moderate snow producing systems head into Southern and Central CA.    A blocking high over BC, CANADA sets the stage for undercutting and a California storm track. Although the block over BC favors Southern California…….According to the ecmwf, the block retrogrades west to Alaska toward the end of the month for a better shot at Northern and Central Ca according to teleconnections.

So far, these systems are not all that impressive moisture wise.  Expect some 5 to 8 inches from the Wednesday-Thursday system on Mammoth Mt, with another but weaker system Friday night into Saturday.   Daytime high this week will average in the 30s and 40 while lows in the Teens and Twenties.  In the Town of Mammoth, expect between 2 and 5 inches by Thursday with a few more inches Saturday.

This is the last weekend of Winter and the Dweebs have spring fever, longing for highs in the 50s….  The Vernal Equinox arrives early this year on Wednesday the 20th at 1:58 PM. Apparently, this is just in time for more snowfall….

Another unsettled pattern begins early Wednesday morning and should continue a few days.  Snowfall will be in the light to moderate range.   This new pattern is nothing like the ones of February. The system for Wednesday will push into Southern CA and become closed off with wrap around circulation and snowfall highlighted above 6000 to 7000 feet.  In that the upper flow is Southerly to begin with, no orographics are indicated as the system moves in to enhance precipitation.  Best snowfall may be coming in from the ENE. Expect about 2 to 4 inches in town and some 4 to 7 inches on the mountain….  Another system will move in later next weekend. That one “may” do a bit better as it comes in a bit further north, however,  it too looks splitty and thus tricky!.   More will follow after the weekend storm….. With an amazing snowpack….it does not take much to freshen it up!


Don’t Forget…..IKON Passes for winter 2020, are on sale now at the lowest prices of the year…..


Stay tuned to Mammoth Best Weather for the Dweebs!
