Relatively cool but sunny conditions will continue across the region today. In addition, gusty north winds will persist through Monday. Sunday into next week increasing heat is expected to occur across interior valleys.

High pressure just off the west remains in place with a trough over the intermountain west. This continues to bring mostly clear skies to the area this morning. Temperatures inland may warm slightly over yesterday to slightly above seasonal normals. Winds will remain breezy today, although they may be a bit lighter than yesterday. Tonight a shortwave moving down the east side of the ridge off the west coast will bring some more coastal clouds to the Humboldt Bay region. Frost is possible again tonight in the colder spots. Sunday temperatures inland are expected to be a few degrees cooler due to the aforementioned shortwave. Winds may diminish slightly as well

Monday the high pressure off the coast starts to slowly move onto the coast. This will warm temperatures inland and allow winds across the interior to start to diminish. Tuesday and Wednesday inland temperatures will continue to warm up with highs reaching the low 90s in the interior valleys. Offshore flow is expected to keep the coast fairly clear Monday and Tuesday with the upper level ridge axis off the coast. Wednesday and Thursday as the ridge starts to push off to the east the marine influence will increase and there will likely be marine clouds again. Friday most ensemble members are showing some sort of trough moving onto the west coast, but only a few of them are actually showing any precip. MKK

High pressure continues to strengthen offshore, tightening pressure gradients. Gusty northerly winds and steep seas persist in all CWA waters, with winds just shy of gale force in the northern inners. Respective gale/haz seas warnings continue in response. Other than a brief reprieve in the northern outer waters Sunday morning, expect strong northerlies to build back in the afternoon through early next week. /EYS

Fire Weather
This morning the highest peaks are gusting to 30 to 40 mph but the lower elevations are seeing much lower winds. Many of these windy locations are seeing RH recoveries of 50 percent or higher. There are a few isolated spots that are seeing RH in the 20 to 30 percent range this morning. This afternoon RH will drop into the teens in eastern Trinity, eastern Mendocino and Lake counties. This will combine with northerly winds 10 to 20 mph with a few gusts to 30 mph. This will create elevated fire weather conditions, but vegetation is not considered dry enough to warrant a red flag warning. Tonight recoveries are expected to improve as the shortwave moves by the area, although winds will remain elevated. Sunday the RH is only expected to drop to around 20 percent in the driest areas, although winds will remain elevated. Sunday night winds will remain elevated and recoveries will be moderate to poor once again. Monday the winds will start to diminish, although a warming and drying trend is expected to through the middle of the week. MKK
