341 FXUS66 KEKA 230710 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 1210 AM PDT Thu Jul 23 2026 .SYNOPSIS...Drier weather is expected late in the week with temperatures near or slightly below seasonal normals for the interior. && .DISCUSSION...Thursday through early next week, the surface level low pressure system will move away from Northwest California while the upper level low will still exert influence over the region. Cooler, more seasonal temperatures will continue for the whole region late this week and through the weekend. Meanwhile, a deeper diurnal coastal stratus layer is anticipated along coastal areas. At the same time, an upper level high pressure system centered over the Southwestern US will try to edge into the region bringing generally drier and warmer conditions for interior regions of Northwest California. /JLW && .AVIATION...The exiting extra tropical cyclonic low pressure system brought gusty winds to area terminals Wednesday late afternoon. The backside of this low will continue to linger over the area well into Thursday and possibly early morning Friday as the system stalls just north of the Oregon border. Winds will split northerly and southerly near Cape Mendocino into early morning. High pressure fills in behind the low by the weekend. Otherwise, there is a chance that LIFR flight categories will return overnight into Thursday early morning for a few hours. TAFs are mostly optimistic with visibility not getting less than 1 mile but ceilings could come down to 300ft at KCEC and KACV. Fairly tame winds at KUKI until Thursday afternoon with northerlies around 10-12kts. /EYS && .MARINE...Winds will be easing overnight into Thursday as the dissipating remains of an extra-tropical system continues to evacuate offshore and proceed northbound. The remnants of Tropical Storm Elida will stall just north of the Oregon border in their outer waters well into Friday morning. Winds and seas will be low impact for the remainder of the week and trend northerly again by late weekend as high pressure fills back in and the summer pattern returns. /EYS && .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... None. && $$ NOTE: The full forecast discussion is now regularly issued between 10 am/pm and 1 pm/am. Additional updates will be issued as needed.
