The center of the upper level low will continue to slowly move onshore through the overnight as a secondary trough on the backside of the low shifts south well offshore today. Scattered weak showers offshore will drift onshore overnight, followed by scattered light showers, primarily over the North Bay after sunrise this morning and over the coastal ranges. Coverage of light showers will begin to increase once again by late morning into the afternoon as an upper trough axis shifts east-southeast across our area. There is a slight chance of thunderstorms after sunrise especially from areas where upslope flow will provide extra lift near the coastal ranges and eastern half of our forecast area. Temperatures will be slightly cooler than today, mostly from the mid-50s to mid-60s. Shower activity should mostly taper off by sunset. Rain totals will be light through the day, with up to a 0.25" for low lying areas, and up to 0.75" at higher elevations.

Monday morning will feature some lingering offshore showers that may drift into Monterey County with only a few hundredths of rain expected where it does rain. By Tuesday, low amplitude ridging will begin a pleasant gradual warming trend. A sharpening trough axis extending southwest from a developing system from the Pacific Northwest into the Great Basin will produce a 'back door slider' pattern for the second of the week. Gusty west winds at higher elevations on Wednesday will become northerly and the strongest gusts appear to not exceed 40 MPH attm. Thursday, gusty winds will become northerly behind the 'back door slider' trough axis, with the downsloping component of the winds not impacting temperatures behind the dry frontal boundary pushing south through our area Thursday afternoon. Another round of shortwave ridging Friday will temperatures jump around 5 degrees into the low/mid 70s inland and low to mid 60s along the coast, and more gradual warming through the weekend.
