Temperatures will be on the increase starting today as high pressure builds over the Northeast Pacific. No rain is expected through at least early Thursday.

Extended the Hazardous Seas Warning for the Southern Inner zone 455 through 1am Sunday.

Recent guidance pulls in bands of gale force wind gusts up to 39 kts into the Southern Inner zone south of Cape Mendocino which will generate steep and hazardous seas.

/issued 540am PDT Sat May 21 2022/

UPDATE...Early morning temperatures across southern Trinity County have come in mostly in the mid 30s. So have hoisted a late Frost Advisory for this zone.

Building high pressure over the Northeast Pacific will dominate our weather here in Northwest California through the middle of next week. Warmer interior temperatures and dry weather will prevail as a result. Another round of breezy, albeit less pronounced winds are expected again today across the forecast area, with some gusts in the 25 to 30 mph possible across interior ridges and exposed coastal areas. High pressure is forecast to shift eastward early next week and a couple of weak troughs will pass well to our north. Temperatures will peak on Wednesday, with some of the warmer valleys climbing into the low to mid 90s starting Tuesday. A trough is then forecast to approach the Pacific Northwest on Thursday as high pressure continues to shift eastward. There is a good deal of uncertainty amongst the clusters regarding the timing of the approaching trough. Still though, expect the trough to bring cooler temperatures and perhaps some light rain the latter half of the work week.

AVIATION...North winds will aid in stratus development occurring over the windward slopes of the King Range and adjacent Humboldt Bay hills this morning. That stratus will backbuild and persist in the vicinity of KACV, and possibly continue through the afternoon into this evening. If that scenario occurs, then a cloud deck varying from SCT to OVC at the 1000 ft MSL level will be probable. Otherwise, northwest winds gusting from 15 to 25 kt are expected along the coast this afternoon, while late afternoon destabilization promotes gusts to 20 kt across interior valleys.


North winds varying from small craft to gale force are expected to persist across the outer waters through early next week. In addition, localized gusty north winds will occur near shore, and seas will be steep and hazardous. Winds and seas are forecast to weaken significantly during the middle of next week.


Fire Weather
Drier air and breezy winds will lead to locally elevated fire weather conditions today for portions of the interior. Recoveries are forecast to improve tonight, though some lower afternoon relative humidities will be possible again tomorrow.
