Monday AM May 27th


Mammoth Mt reported 3 inches of new.  Not nearly what was forecasted but fresh powder….

25 degrees early this AM.  Yesterday’s high 35.  30 degrees below normal.

Were deep in the solar minimum…

The weather this week is highlighted by the break down of the blocking pattern over NW territories and Eastern AK.  That should result in warmer temps by weeks end and next week.

However…..Upper long wave Trof will stay over the west this week with showers and thunder just about everyday…..


  • Temperatures will gradually rise each day this week….depending upon cloud cover.



There is really two parts to this whole pattern that worth mentioning.  Of course the pattern highlighted by high latitude blocking over the northwest territories of Canada that is forcing the long way Trof quasi stationary over the far west. This blocking along with negative AO has been with us for a good part of the winter.  It is still affecting the Conus today.

Additionally, you have the high angle of mid July like sun that plays heavenly upon the convective process.  Do not be surprised if you hear about cold core funnels Sunday over parts of CA and Nevada, as the cold pool from this system is associated with 1000-500mb 540 DM thickness pool approaching the SFO early Sunday AM. Very unstable by the afternoon.

Will look at the lifteds tomorrow AM.


TOML.  Stands to pick up 2 to 4 inches at the Village and 4 to 8 on Mammoth mt by Monday AM.MORE LATER….


Sunday AM

qpf has been bumped up with some 6 to 10 inches possible on Mammoth Mt.  3 to 5 in town by Monday AM. It will be a Chilly day today in town with highs in the 30s. Lows in the low 20s.

Extended models are showing a remarkable turn around in the week two outlook with much above normal temps developing during the latter part of the first week of June into the 2nd week of June. This would create a whole new set of  problems with runoff,  as highs would climb into the 80s in Mammoth during the week two period.


stay tuned…….
