The air will slowly dry out Monday with gusty north-northwesterly winds. Winds will ease by Tuesday morning with a cold air mass settling in. Patchy frost will be possible approaching the coast with higher valleys -- especially in the south -- experiencing another freeze. Temps will warm through mid-week as a massive storm develops in the North Pacific. More on our local impacts in the extended section below.
AIR QUALITY: Good
Monday: Mostly sunny with gusty north-northwesterly winds. Chilly, with highs in the mid-50s to low 60s.

***FREEZE WARNING***
...for interior areas of Monterey County and San Benito County in effect from 12AM Tuesday until 8AM Tuesday.
*freezing temperatures as low as 26 expected.
*Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing. Cold conditions will be hazardous to sensitive populations such as unhoused individuals. Cold Conditions can lead to hypothermia with prolonged exposure.
Take steps now to protect tender plants from the cold.
Be sure to open sink cabinet doors and/or drip faucets. This may help reduce or prevent damage to uninsulated pipes and other plumbing.
**FROST ADVISORY**
...for coastal Santa Cruz County, the Santa Clara Valley, and the interior mountains of Santa Clara County in effect from 12AM Tuesday until 8AM Tuesday
*Temperatures as low as 34 will result in frost formation.
*Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing. Cold conditions will be hazardous to sensitive populations such as unhoused individuals.
Take steps now to protect tender plants from the cold.
Be sure to cover or tend to sensitive plants and vegetation as they may be damaged by frost.
Tuesday: Mostly clear and cold in the morning with patchy frost for coastal cities and widespread frost to freezing conditions for inland valleys. High clouds increase and become thick at times during the day. Highs remain cool, in the mid-50s to low 60s. Light winds.
Extended: By mid-week, a strong storm system with an atmospheric river will be impacting the Pacific Northwest all the way down into northern California. It appears now that by late Wednesday, we may catch the southern edge of the AR, bringing rain to the northern portions of our viewing area. Since we'll be on the front side of it, we'll have warm and gusty southerly flow, sending highs back above normal. A strengthening ridge to the south will likely push the AR back north for Thursday, though we may still have to watch for rain in the north. By Friday/Saturday, the weakened AR will likely finally move through the Monterey Bay Area along with a cold front. Widespread rain is expected during the period, but at the moment it doesn't look all that heavy. Still, this is likely to be the wettest system of the season so far. Some indications show the "storm door" remaining open behind this system which could lead to additional rainfall through the weekend. Lots of things could change -- intensity, timing, etc, so please stay tuned to my forecast!
