Synopsis for northern california waters - Northerlies slowly accelerate for the next couple of days, reaching gale force in the southern waters by this afternoon and the northern waters by tonight. Northerly seas ramp up with the increasing winds, peaking over 15 ft at 11 seconds by Wednesday night. Winds then quickly weaken by the end of the work week.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 439 AM 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
In the departure of a weak front, quickly clearing skies allowed for temperatures in the drier interior valleys to drop to chilly, frost producing temperatures this morning. With increasing subsidence from building high pressure, and clearer skies, more frost development can be expected overnight. The expansive Pacific ridge will begin quickly amplifying today, and this strengthening will continue 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



AVIATION
Northerly winds will begin to ramp up throughout today as a ridging pattern continues to build into the region. Sustained winds between 15 and 20 knots are anticipated for coastal terminals this afternoon, with gusts to 25 and 30 knots likely. Northerly winds for more interior areas will be weaker, but still could potentially reach 10 knots by the afternoon. Elevated northerly winds are expected to reemerge at the terminals each afternoon into Thursday. Stronger winds will most likely keep coastal stratus to a minimum.

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.
