The high pressure ridge that gave us the sunshine has moved eastward to be replaced by a trough of low pressure.  A  frontal system split it two and moved in bringing back the rain. Another storm system has moved in behind this one. Yet another storm system will move southeastward into California between Friday night and Saturday as high pressure holds off a cold front that will approach from the northwest.

Advisories: NONE AT THIS TIME.
