This morning's satellite picture (below) shows a frontal system approaching the coast and being weakened by the high pressure area that is still over the western U.S. We will see a few high clouds from this system later today and Sunday. Temperatures today and Sunday will be a little above normal and winds will be light. Monday and Tuesday we will continue mostly clear with normal or slightly above normal temperatures and light winds.
Wednesday the high pressure ridge weakens and the jetstream will drop southward. This will allow a low pressure trough and frontal system to pass through the north state late Wednesday and Thursday (see map below) with another system on Friday. Neither of these systems are very strong but they will bring light rain or showers to the higher elevations with the chance of a light shower in the north end of the valley. Moderate south to southwest winds will precede these systems.
High pressure rebuilds off the coast late Friday and next weekend looks sunny and mild.
