AREA FORECAST DISCUSSION National Weather Service Eureka CA 300 AM PDT Fri Oct 30 2020

SYNOPSIS. Dry weather is expected through early next week, with chilly mornings and warm afternoons. Skies will generally remain clear except for occasional coastal clouds and patches of fog.

DISCUSSION. More widespread stratus and fog has returned to coastal areas and the adjacent waters of northwest California this morning. This has occurred as a transient shortwave disturbance moves over the Pacific NW and flattens out the ridge which has been in place the last few days, yielding an uptick in boundary layer moisture along the North Coast. Stratus is generally confined to the immediate coast as a lingering weak offshore gradient inhibits any intrusion into the coastal river valleys. The marine layer remains fairly shallow per profiler data, which should allow stratus to scatter out by late morning and yield another sunny and mild afternoon at the coast, with warmer temperatures inland. Very dry conditions will persist across the interior, where minimum RH values will again struggle to get out of the teens. Winds will remain on the light side with the exception of some very localized gusty conditions and critical fire weather concerns on a few exposed ridgetops.

The ridge will quickly rebuild overhead tonight and remain in place through the weekend, with continued sunny skies and seasonably warm temperatures for most of the area as humidities slowly moderate across the interior. Expecting stratus to return tonight and become a little more extensive along the coastal plain through Saturday morning as the offshore gradient dissipates.

Northern portions of the area may see some light rain Tuesday into Wednesday as the ridge shifts eastward and is replaced by a period of quasi-zonal flow aloft during the middle of the week. However, a more substantial pattern change is depicted by global ensembles late next week into the weekend as deep troughing is being hinted at over the western CONUS. This would signal a much cooler and potentially wetter pattern as we move into the second week of November, although the details are still very much up in the air. Stay tuned. /CB

AVIATION. Marine stratus has developed along much of the coast this morning, with ceiling and visibility impacts occurring at KACV. Similar impacts may develop across KCEC toward sunrise. Stratus will likely clear along the coast by afternoon, followed by redevelopment and inland intrusions tonight, particularly at KACV. Otherwise, inland areas will experience VFR conditions during the next 24 hours, with the exception of patchy nocturnal valley fog, as well as locally dense smoke occurring in the vicinity of ongoing active wildfires. JMG

MARINE. North winds are forecast to strengthen today into Saturday over the outer waters. Gusts to 30 kt and steep seas from 5 to 8 feet will be probable, particularly over the southern outer waters. Winds and seas are then expected to subside going into Sunday. Otherwise, a long period northwesterly swell is forecast to move through the waters Sunday afternoon into Monday. JMG

BEACH HAZARDS. A long period northwesterly swell is forecast to move through the coastal waters Sunday afternoon through Monday. This swell will increase the threat for sneaker waves along area beaches, particularly during Monday. JMG
