This mornings progs, shows a short wave ridge building into Northern Ca tonight with the HT 500 ridge axis over KMMH at 1800z Wednesday. No doubt that Wednesday afternoon will have light winds and significantly warmer temps with the high sun angle of May. It will be warmer on Thursday as well. The Dweebs are noting that there is some directional divergence during the PM as the next trof draws near, no precip noted in the progs for that afternoon through. Temps will peak out Thursday afternoon with highs in the low 60s for Mammoth.

By Friday, Southwest flow will be increasing in advance of the next trof during the afternoon. It will become quite breezy during the afternoon over the crest with stronger winds likely for Saturday. On Saturday the upper ht 500 trof becomes negative tilt. This will eventually tend to break off energy further south into our state, later in the weekend with precipitation a possibility.


Not much change in our weather since late April other then the strength of the jet continues to weaken as is usually the case as we continue in time toward Summer. Several earth-science, scientests continue to blame the effects of a long solar hibernation and a continuing lag in the solar ramp up in sunspot activity to the severitiy of our Spring weather. Others blame Global warming. 

Yes, the Sun has been more active this Spring with an increase of sunspots, but it is well below the norm of what is usual.  The Dweebs note that the PDO is still quite negitive with much cooler then normal waters over the Eastern Pacific. This tends to keep trofing over the far west and the eastern pacific. What will be interesting, is to watch the SST anomalies throughout the Summer and Borial Fall. At the moment (pos) SSTs are increasing in the Nino 1 and 2 regions, However for the time being our weather is probably being more influenced by :

1. The continuation of the colder then normal SSTs in the Eastern Pacific.

2. Possibly the Enhanced Phase of MJO. See:

The 6 to 10 day outlook keeps below normal temps here in California with above normal chances of precipitation.

Time to get the Sun Dance going!!!
