Sunday Am Update:

An Eastern Great Basin Slider will bring cooling today along with gusty higher elevation Northerly winds.  The upper ridge in back of the slider will build in Monday bringing about 10 degrees of warming over today’s highs. The next weather system will move through the pacific NW Tuesday then into the Rockies Wednesday bringing more wind and cooling Tuesday into Wednesday. This too is a dry system for Mammoth Lakes. The NW flow pattern shift east next Thursday with height rises over the far west. This will bring warming back into our area Thursday, into that following weekend.  So the week ahead is dry for the Mammoth area.

It will not be until that last week of April that the next opportunity arrives for some precipitation along with unsettled weather.    (Sometime between the 21st and the 30th)


The Dweeber…………………………….:-)


Weak upper low off the Southern Coast is spreading high cloudiness over California. Although it is weak, A deformation zone (Surface Convergence) will form to the  North and NE of the Low allowing some showers and or TSRWs to form over the Sierra and high deserts of Eastern CA, as well as West Central NV this afternoon and evening. The low is expected to move onshore over the Channel Islands at 09Z Saturday.  Another weak short wave will dive into the Rockies Sunday. Although The new WRF is further west in the 12Z Friday Run, I’ll stick with the new 12Z Friday GFS as it takes the cooling well east of our area. There will probably be a few degrees of cooling Sunday with Sunny Skies. The next Stronger system moves in Tuesday with strong gusty winds, cooler temperatures and even the chance of snow showers!  Highs on Wednesday will be in the 40s. Another cool short wave may follow on Thursday.


For people in the United States, an extraordinary series of lunar eclipses is about to begin…..ones that have only occurred 3 times in the past 500 years!

The action starts on April 15th when the full Moon passes through the amber shadow of Earth, producing a midnight eclipse visible across North America. So begins a lunar eclipse tetrad—a series of 4 consecutive “Blood Moon” total eclipses occurring at approximately six month intervals.  The total eclipse of April 15, 2014, will be followed by another on Oct. 8, 2014, and another on April 4, 2015, and another on Sept. 28 2015.

“The most unusual thing about the 2014-2015 tetrad is that all of them are visible for all or parts of the USA,” says longtime NASA eclipse expert Fred Espenak.
