Synopsis
Breezy winds and milder interior temperatures will continue today. A warming trend will kick off this weekend and continue into next week with no rain expected.

Brisk northerly winds will continue to peak this morning as drier air continues to filter in to the area. A Wind Advisory is in effect through 1 p.m. for portions of Lake County, with some gusts to around 50 mph possible. The combination of brisk northerlies and low humidities will lead to an elevated fire weather threat for portions of Lake County today. Please the fire weather discussion below for more information. Some chilly temperatures are being observed this morning across portions of Humboldt and Trinity, so it does look like the advisory verified in a couple spots. Temperatures will be slightly cooler this afternoon compared to yesterday, but a warming trend will kick off tomorrow as high pressure builds over the Northeast Pacific. Overnight temperatures are expected to be a little warmer tonight, so don't think there will be a widespread frost threat. Winds will begin to ease this afternoon, but breezy winds will still continue into the evening hours. High pressure is forecast to persist through early next week, so temperatures will be seasonal along the coast and quite warm across the interior. The forecast remains dry through Wednesday and guidance is then hinting that the ridge will shift eastward as a trough approaching on Thursday. Confidence is not all that high, so stuck to the NBM guidance during the late next week period.

Marine
Gale force northerly winds and steep, hazardous seas remain across the waters through Saturday. Sustained wind speeds up to around 35 kts with gusts around 45 kts are expected to persist through late tonight as high pressure over NEPAC and a thermal trough near the coast continue generating a moderately strong pressure gradient. Winds ease a bit on Saturday to near gale sustained winds as the pressure gradient begin to relax, but gale force gust winds will continue through Saturday. Seas will remain very steep from 10 to 15 foot through Saturday. On Sunday, winds will ease a little bit more as a frontal system approaches early next week, but fresh to strong breezes will continue.

Fire Weather
Dry air and increasing northerly winds will lead to increased fire weather concerns across the southern interior again today. Winds will peak this morning, with some gusts to around 50 mph possible over the ridges of eastern and southern Lake County and the Yolla Bollys. Humidities are forecast to dip into the teens this afternoon. However, fuel moisture remains near to slightly above normal for this time of year in that area. Have continued to headline the threat. /SEC&JAW
