Rain in Norcal on its way

Fairly dry and warm condition are forecast through midweek, except for a slight chance of rain in the north bay on Tuesday.  Chances of rain increase by Thursday and then greatly increase into this weekend.


The week will start out dry with patchy morning fog in various locations throughout the county.  A light system far north of the county is expected to develop on Tuesday, but is not expected to produce very much rain.  Rain, if any, from this system will be only along the northern county border.  Fairly dry conditions are expected throughout most of county on Wednesday with a very weak system moving into the area late Wednesday night to early Thursday morning where very light rain is expected.  Then,  a much stronger storm is expected to move into the area by late Friday and will produce rain throughout the remainder of the weekend.  Precipitation amounts may range from 1.35-inches along the eastern side and southern portions of the county, and up to 2.54-inches of rain along the coast, higher elevations and along the northern county boarder.  This system is expected to produce heavy rain at times with strong winds throughout the weekend and into next week.
Mid-range Climate Projections: The 6 to 10-day climatological outlook shows above normal precipitation probability.  The 8 to 14-day outlook also shows a probability above normal precipitation amounts.
Longer Range Climate Projections: The latest monthly outlook for precipitation shows March as having greater probability for above normal than normal, or below normal precipitation. Mar-Apr-May also shows nearly a 33% probability for above normal than normal, or below normal precipitation.  See these and other projections, as well as current drought conditions, at: https://www.cpc.ncep.noaa.gov/index.php
