Coming Gloom
I hope you were satisfied with the sunshine these past few days ‘cause the times, well, they are a-changin’. There will be a brief break in low pressure aloft as the trough to our north recedes into the flow. Short-ridging will slightly compress the marine layer, warming inland/mountains areas but also adding stability to the low levels and directing a more westerly component of the northwesterly onshore flow. The net result will be the return of low clouds to the coast—at first partially on Wednesday. Then, a new area of low pressure aloft develops just off to our west which will strengthen and deepen that more westerly onshore flow. This will reinforce the new marine layer clouds and will really cut through temperatures both on the coast and inland. We’ll probably squeeze some drizzle out Thursday and Friday with this low nearby. It will also eventually be absorbed into the flow and the mid-term models are showing weaker troughing lingering on the coast into next week. Temperatures will then likely slowly warm back up through the weekend.
AIR QUALITY: Good
***GALE WARNING***
... for the near coastal waters from Point Pinos to Point Piedras Blancas extended until 9AM Wednesday.
NW Winds 20-30 kt gusting to 40 kt with seas 8-10 feet possible. Mariners are advised to remain in port, seek safe harbor, alter course and secure the vessel for severe wind and seas.
Overnight: Low clouds slow to return, but eventually filling at least the southern half of the bay and perhaps nearby valleys. Lows will be slightly warmer than the previous morning but still cool for this time of year with widespread mid to upper 40s on the coast and upper 30s to 40s inland. Breezy northwesterly onshore winds for the exposed coast and major valleys, slowly tapering off overnight.
Wednesday: Clouds linger on the south half of the bay but remain clear for most other areas. Cooler on the coast with highs in the low 60s to low 70s—warmest on the north side of the bay—but warmer for some areas inland with highs ranging from the upper 60s to mid 80s. Northwesterly onshore winds will be strong at times around the river mouths and into the valleys.
Thursday: Widespread low clouds in the morning with patchy drizzle mainly on the east side of the bay. Then, becoming mostly cloudy on the coast and partly cloudy inland. Much cooler with coastal highs in the upper 50s to mid 60s and mainly 60s to low 70s inland. Westerly onshore winds will be strong in the afternoon for the river mouths and major valleys.
Extended. More clouds and drizzle Friday morning, though some scattering of the marine layer clouds possible in the afternoon. Temperatures will slowly warm both on the coast and inland through the weekend into early next week under partly cloudy skies. Highs will be closer to normal by Monday or so. Winds look to pick up again mid-week next week.
