Chilly Changes Ahead

We re in between weather systems until Friday morning, with the focus shifts to areas of patchy frost and fog (possible freezing fog in the North Bay) for Thursday morning. Leftover moisture in the form of patchy clouds may prevent too many places from dropping to near freezing, but for our wind-protected inland clear sky valleys overnight, some frost may be possible. An area of low pressure will move north to south down the coastline later on Friday bringing more rain to the Bay Area. Friday looks to be especially chilly as cool northeasterly wind funnels in chilly air into the Bay Area and our Gulf of Alaska-based rain maker tosses in cold rain at times into Saturday. Snow levels will probably dip low enough for a dusting of snow on our higher Bay Area peaks above 3,500-4,000 ft. The low will slowly begin to push south by Saturday evening leaving Sunday looking mainly dry (possible exception may be areas south of San Jose) as the low now provides rain across Southern California. We should squeeze in a dry New Year s Eve and NYD with possibly some rain across the far North Bay. The item to watch by the middle of next week is a very moisture rich jet stream aiming in on Oregon and extreme Northern California. This will lead to a chance for more rain around Wednesday of next week.
