Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
strong northerly winds continue through the middle of the week, with gale-force gusts expected over the outer waters and near the big sur coast. Winds slowly ease Thursday morning to become fresh to moderate. However, as a result of strong winds in the early portion of the week, significant wave heights will build to heights of 15 to 16 feet over the outer waters by mid-week. SEa conditions will be hazardous Tuesday and Wednesday with gale warnings issued for portions of the coastal waters. By the late week into the weekend, winds ease to become gentle, significant wave heights gradually diminish to 5 to 7 feet, and dry weather continues as high pressure dominates.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 250 PM PDT Tue May 7 2024

SYNOPSIS
A significant pattern change from the cool, wet, winter- like conditions is currently underway. A building expansive Pacific ridge of high pressure will bring quickly warming temperatures and strengthening N to NE winds. This combination of elements will allow for unseasonably warm temperatures closer to the coast.



DISCUSSION
With increasing subsidence from the strengthening high pressure offshore,the clearing of skies will continue to trend and will promote more frost development overnight. The expansive Pacific ridge will continue amplifying today, and will persist through late in the week. Outside of the immediate coast, temperatures will be noticeably warmer today for most. Northerly winds will be increasing today, and by the afternoon, gusts of 25 to 35 mph are forecast for the exposed coastal areas. Interior ridgetop northeasterly winds will ramp up tonight, and will become strong (gusts over 50 mph) from southern Trinity southward, particularly over the highest ridges of Lake County through Thursday morning.

The northerly breezes will be of similar strength on Wednesday as the high further amplifies and an upper trough cuts off and retrogrades west into the Great Basin. This will strengthen offshore winds on Thursday/Friday when the warmest temperatures are expected to the coast. Ensembles guidance holds near record to record highs in the mid to upper 70s to the coast Thursday and likely Friday. Interior valleys will rise to the upper 80s to low 90s. Given the setup and models' difficult ability to resolve the far westward push of warmth from the offshore winds, leaned toward the 75th percentile on Thursday for coastal highs when the most pronounced offshore flow will develop. This will be quite a swing from the below average temperatures of recent days, allowing little time for acclimation. Ensembles generally hold the ridge through the extended, with varying phases of amplification. /JJW /EYS

AVIATION
By mid-morning Sky and Vis became VFR. Any aviation concern today has been "ramping-up" northerly winds near the coast; the cause will be developing offshore high pressure and inland (inverted) low pressure trofing interacting. Therefore, the at/near the coast pressure gradient will tighten; the result will be gusty coastal winds through evening. Windy conditions will result in the lack of coastal stratus into Wednesday. Late Wednesday morning, elevated offshore winds could possibly, and briefly become the catalyst for LLWS at CEC. Inland weather today and through Wednesday is expected to stay inconsequential. /TA


MARINE
A northerly wind regime will become strong and dominant as synoptic ridging sets up over the Western US. Winds will increase to gale force by this evening. These northerly gales are expected to last through Thursday. Gusts above 35 kts in all area waters are forecast with some gusts in the northern outer waters reaching 45 kts by late Wednesday night. Wind waves out of the NW will be steep at 9 to 10 feet in height and as many seconds in period. Seas are anticipated to peak over 15 ft at 10-11 seconds out of the north by Wednesday night. The thermal trough will build toward the coast late in the week resulting in a weakening pressure gradient over the waters and likely some weak southerly return flow near the immediate coast.
