A NNW orientated upper jet will keep the winds going most of the day today. Gusts in Town will continue in the 20 to 40MPH class. The upper trof is slowly translating eastward. One last Vt Max heading SE will keep the snow showers going for a while longer. CRFC has another .3 inches for the Yosemite area between 4:00am through this afternoon and so another 3+inches is certainly possible over the upper elevations today.  So far 1.49 inches of water has accumulated in the snow melt bucket at the main lodge since the 27th with 15 inches of snow. .56 here at http://mammothweather.com at the 8200foot level. About 6 to 8 inches of snow has fallen.


Winds will begin diminishing later tonight but will remain gusty over the crest through Friday. Winds in town will calm down by tomorrow.

8000ft High temps are expected in the low 30s today then mid to upper 30s Friday….40s Saturday and 50s Sunday and Monday as the upper ridge slowly builds into California and over the far west by Sunday/Monday.

The next system will be a splitting system and with most of the action possibly to our north (see comment below). Expect cooler weather Tuesday and Wednesday with a  chance of snow.

Longer Range:

Models maybe underestimating the MJO effect upon the pattern for next week……MJO is in its prime position to work its magic……Further retrogression is possible with larger storms coming in further to the south.

Even the system for Tuesday/Wednesday may surprise us based upon the current forecast of a slight chance of snow……

The MJO:

Has strengthened and moved into early Phase Space 3. Further retrogression is expected in the long wave pattern across the north pacific next week. Even though the AO index is positive….this maybe very significant for Snowfall and Water for California.
