Quick Morning Update. Some Fog and Cold.

A few things to note as we head into this fabulous weekend.  This morning, and more so this evening and Saturday morning, we have conditions along the coast that may cause an encroaching marine layer.  Yup, that is right - fog.  So don't wake up early on Saturday morning to expect a sunrise walk on the beach.  I know this is a bummer, but you can always head to the local hill tops to enjoy some sun, and it should burn off on the coast by late morning.  Sunday should be mostly sunny.

As for the Central Valley, we have calm, clear weather, and an inversion has set in.  That is when the cold air sinks into the valleys (because it is heavier than warm air) often resulting in a thick blanket of fog.  This fog is thicker and more persistent than its coastal friend.  Expect it to slow traffic through the valley, especially from evening to late morning.  Drive carefully out there, especially those racing up to the Sierra for this weekend.

BTW, the Sierra are way above both fog layers and should only see sunny skies with some passing clouds.  But that is where the cold comes in.  Today should see temperatures in the mid to high 40s, but dropping over the weekend.  Saturday look for high 30s and on Sunday we may not even break freezing at 7000'.  Use caution, as those sunny aspects will have some mid winter California ice (much softer than the ice in Vermont).  Still, this is the stuff that can catch you off guard, and break some bones.

Coastal temperatures do not drop off as much, but expect low 50s by Sunday and Monday.  Still looks like we have have a chance of rain starting as early as Tuesday.  Too hard to tell if we get just a passing storm, or a run of systems - regardless, don't miss this great weekend we have on tap.
