SYNOPSIS

18/849 AM.

There will be a few showers this morning along the Central Coast and light snow over the Grapevine, otherwise it will be sunny and dry but cool and breezy. Another storm will move into the area Thursday bringing more rain and mountain snow. Then dry weather Friday and Saturday before another storm is possible Sunday or early next week.

LONG TERM (SAT-TUE)

18/203 AM.

No changes were needed to the long term discussion as much of the forecast remains the same.

Saturday will be the nicest day of the next 7 as a weak ridge passes overhead. It will be a mostly sunny and dry day. 3 to 6 degrees of warming will bring max temps up into the 60s.

Another large Gulf of Alaska system moves down and into the PACNW Sunday and will bring moist cyclonic flow to Srn CA once again. The ensembles are all over the place and the forecast broad brushes 30-40 percent chances of rain across the entire area Sunday through Tuesday. This reflects mdl confusion and not a multi-day rain event. This system does not look like it has that much moisture to work with and rainfall amounts at this time do not look that impactful.

There is another storm that models are targeting for later next Tuesday into Wednesday but this one appears to be a weaker system with snow levels at or above 10,000 feet.
