FXUS66 KEKA 060717 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 1217 AM PDT Wed May 6 2026 .SYNOPSIS...Weak high pressure building into the area will gradually warm inland temperatures through Thursday. Closer to the coast widespread low clouds will linger keeping temperatures cooler. Friday will see slightly cooler temperatures and more clouds. For the weekend and into early next highs are expected to warm each day with many inland areas seeing the 90s by Monday. && KEY MESSAGES: Near to above normal inland temperatures Wednesday and Thursday with some cooling Friday. Breezy north winds this weekend with well above normal temperatures inland. Minor to moderate heat risk is possible on Monday in Mendocino, Lake and Trinity counties. .DISCUSSION...High pressure is building over the area in the wake of a departing low. This will bring clearing skies and warming temperatures for some areas of Trinity county. The coastal counties and Lake county are seeing widespread stratus this morning. Some portions of Trinity county are also seeing stratus. This will likely slow the warming trend in these areas on Wednesday. Clouds are expected to clear back closer to the coast by the afternoon, but the coast is expected to remain fairly cloudy. Wednesday night into Thursday the area is expected to see less stratus, but it is still expected to make it quite a ways inland. This will again likely keep temperatures cooler than expected in these areas. Thursday night into Friday a weak front will bring some mid level clouds and cooler temperatures to Trinity county. This may bring some drizzle to the coast, but at this point no real rain is expected. Friday night into Saturday northerly winds are expected to increase. Offshore flow is expected overnight with breezy afternoon winds. Inland areas are expected to warm again on Saturday and with mostly clear skies areas closer to the coast will likely warm up too. The breezy northerly winds typically keep the immediate coast in the low 60s. The warming trend is expected to continue into early next week. At this point the first day expected to see moderate heat risk in the far inland areas is Monday. However, there is some potential an upper low could develop off the coast weaken the wind flow allowing clouds and marine air creep into the coastal counties limiting the heating potential. MKK && .AVIATION...Widespread stratus remains in place across the coastal counties as well as Lake county. CIGS are generally MVFR in this stratus in the valleys. Towards sunrise as the high pressure builds in this is expected to slowly flatten the stratus and lower the CIGS. Some areas may drop into the IFR category. Through the day Wednesday CIGS are expected to lift and clear in the inland areas. This coast is expected to remain cloudy, but CIGS may lift to VFR or near VFR. Northerly winds are expected to increase slightly in the afternoon to around 10 kt. MKK && .MARINE...The winds remain fairly light out of the north this morning, around 5 kt in the north to 10 kt in the south. Later today and this evening winds are expected to increase slightly to around 10 to 15 kt. This will develop some 2 to 4 foot wind driven waves. In addition there is expected to be a couple northwest swells. It looks like one will be around 12 to 14 seconds and one around 8 to 10 seconds. These both look to be around 3 feet. Winds are expected to remain around 10 to 15 kt through Thursday evening. Thursday night into Friday a weak front approaching the area is expected to bring lighter winds north of Cape Mendocino. Only around 5 to 10 kt and these may briefly become west or southwest. Farther south the winds are expected to increase to around 15 to 20 kt. Behind the front on the weekend winds are expected to increase to near gale or gale force as high pressure builds in again. There is expected to be a fairly small northwest swell through much of the period. Friday night and Saturday behind the weak front the swell may increase slightly with periods jumping up to around 15 seconds, but heights remain around 3 or 4 feet.
