AREA FORECAST DISCUSSION National Weather Service Eureka CA 409 AM PDT Mon Apr 19 2021
SYNOPSIS. Cool and cloudy conditions will persist along the coast for the next few days. Interior locations will remain sunny and warm, although slightly cooler than in recent days. A passing disturbance will bring patchy drizzle to coastal areas tonight into Tuesday morning, with a few showers possible inland through Tuesday afternoon.
DISCUSSION. Extensive marine stratus and patchy fog are once again present along much of the West Coast this morning as the upper level ridge axis remains directly overhead. Stratus has pushed a little farther up the coastal river valleys of northwest California compared to previous mornings as the marine layer begins to deepen, per current profiler data. The ridge will flatten out later today as it is temporarily bisected by an approaching shortwave trough poised to move over the CA/OR border region tonight. Sensible weather impacts from this development will initially be somewhat negligible as coastal areas remain cool and cloudy while interior locations stay sunny and warm, albeit 5 to 10 degrees cooler than Sunday in most locations. However, the approaching trough will serve to continue to deepen the marine layer over time as flow shifts back onshore. This will allow the marine influence to penetrate farther inland and quell the recent fire weather concerns given slightly cooler temperatures and higher humidity values than recent days. A deeper marine layer coupled with orographically induced lift on the windward side of the King Range plus weak forcing from the approaching trough will create an ideal setup for drizzle later this evening through Tuesday morning, which may be enough to squeeze out a few hundredths of an inch of precipitation along the Humboldt Coast tonight. Elsewhere, the passing shortwave will also be capable of supporting a few showers over the higher terrain of Trinity and eastern Mendocino County through Tuesday afternoon, but models have substantially backed off of thunder potential as most of the forcing looks to pass through earlier in the day on Tuesday.
Beyond Tuesday, ridging will gradually build back in over the latter half of the week and support continued dry conditions, with warmer than normal temperatures across the interior while the marine layer continues to keep coastal locations cool and cloudy. Ensemble guidance and cluster analysis continue to point to an increasing probability of large scale troughing developing over the West Coast towards the weekend, lending hope for some late season beneficial wetting rain across NW California even as details remain elusive. /CB
AVIATION. Solid LIFR ceilings were observed along much of the coast early Monday morning, but visibilities were in the VFR category, and are expected to remain so during the rest of the morning. Short-term model guidance indicates ceilings may rise slightly this afternoon, and perhaps become broken for an hour or two. However, a deep saturated marine layer is forecast to spread inland this evening/tonight across coastal Humboldt/Del Norte Counties as well as portions of Mendocino County. Locally strong ascent due to strengthening low-level northwesterly flow near and upwind from the King Range will also favor drizzle across much of the Humboldt Bay area tonight, including KACV. Farther south at KUKI, the marine layer is forecast to be sufficiently deep to spread east across the coastal hills/ridges, such that IFR/LIFR ceilings may develop across Ukiah toward 12Z/20th.

MARINE. Little change in the marine forecast is expected. Surface high pressure over the NERN PAC is on track to strengthen during the next 24 hours. The pressure gradient will tighten in the vicinity of coastal NWRN CA and aid in the development of small craft northerlies across all coastal waters by Monday evening. Winds are forecast to strengthen further to gale force over the outer waters by Tuesday afternoon. Gusty north winds and steep hazardous seas will persist through Wednesday. Winds and seas are then forecast to weaken during the second half of the week.
