Synopsis for northern california waters - Winds are gradually training from the west as the previously dominant southerlies exit with the front. A northerly wind regime will become strong and dominant as synoptic ridging sets up over the western us, ramping up into gales on Tuesday which will last through to Thursday. Expect gusts above 35 kts in all area waters with some gusts in the northern outer waters reaching 50 kts late Wednesday night. Wind waves out of the nw will be steep and square, 9 - 10 feet in height and as many seconds in period. Seas peaking over 15 ft at 10-11 seconds out of the north by Wednesday night.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 259 PM PDT Mon May 6 2024

SYNOPSIS
After a cool and damp period, trending warmer for the work week, with strong north winds for mid-week, especially along the coast and over the water.

DISCUSSION
Ensembles indicate the weather element most likely to stand out for this time of year is wind speeds from Tuesday through Thursday. Windy over the waters Tuesday through Thursday, and over land, especially on Tuesday and Wednesday on ridges. Probs near 100% for gale force gusts in outer waters Tuesday night through Wednesday night. Watch out on Tuesday along the coast as ensembles are forecasting a 54% chance of gusts over 35 mph for Eureka and 83% for Fort Bragg, 52% for Crescent City. Lake County looks particularly targeted for Wednesday and Thursday with ensemble chances of over 35 mph for Clear Lake are 57% for Wednesday and 53% for Thursday.
Crescent City is not out of the woods for wind gusts Wednesday as probabilities are 53% for gusts over 35mph.

Widespread agreement among ensembles of one last cool night from the influence of the soon to be exiting shortwave trough (frost will be somewhat limited due to sky cover), with anomalously strong ridging arriving Tuesday, with a warming trend heading through Friday as an extreme positive tilt to the upper ridge develops, reaching into the northwestern United States, including northern California, as positively tilted troughing holds on over the Great Basin and central Rockies. Expect anomalously warm high temperatures and quite warm low temperatures, with potential for some records to fall from Wednesday through Friday. Temperatures could reach mid 70s for highs on Thursday on the coast and mid 80s for some interior valleys. Lows are forecast in the 50s on the coast for Friday and Saturday mornings.

As for precipitation, HRRR indicates some drizzle potential, especially north this evening and into the early overnight. After tonight, ensemble meteograms indicate a long stretch well into next week of dry weather and this is consistent across the board.
Confidence is high for this scenario. Also, ensembles point to enhanced stratus potential for Thursday morning in the marine layer, so this is indicated in the forecast. /MH



AVIATION
Light rain will trail off as the evening approaches for the coastal terminals. Gusty southerly winds have eased to 10 knots at KCEC as of 1pm with flight categories have improved to MVFR as well. KACV is also getting intermittent rain as swaths of low decibel returns are indicated via radar. KACV will improve to MVFR as well with ceilings lifting by nightfall. Winds are expected to veer west and eventually northerly by this evening as the front passes through. Large scale ridging will eventually bring subsidence and clear conditions out for a few days, overnight into Tuesday.
Heavy winds are expected by Tuesday afternoon and last through to Thursday as strong ridging and northerlies dominate the area. /EYS



MARINE
Winds are gradually training from the west as the previously dominant southerlies exit with the front. A northerly wind regime will become strong and dominant as synoptic ridging sets up over the western US, ramping up into gales on Tuesday which will last through to Thursday. The Gale Watch has been updated to a Gale Warning as the event nears. Expect gusts above 35 kts in all area waters with some gusts in the northern outer waters reaching 50 kts late Wednesday night. Wind waves out of the NW will be steep and square, 9 - 10 feet in height and as many seconds in period. Seas peaking 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. /EYS
