SYNOPSIS

A warm, dry, and summer like pattern will peak Saturday. Very light coastal drizzle is possible Monday but otherwise similar weather will continue next week and particularly gusty north winds near shore around midweek.

DISCUSSION

High pressure will peak over the weekend withs highs in the upper 70s across the interior. There remains a slight (15%) chance of some isolated highs even over 80 on Saturday afternoon. Some gusty north winds will remain in the afternoon, but slight weakening may allow for coastal highs in the 60s. Regardless clear and relatively dry conditions will persist.

A very subtle shortwave passing the early next week could bring very light drizzle within the marine layer around Monday, most likely just for Del Norte. Otherwise, the wave will help push strong north wind s into the coast, where north gusts could again exceed 30 mph in the afternoon. Overall conditions will remain dry with interior highs right around 70. Most models have now trended towards high pressure lasting all next week with with little more than drizzle (20% chance) possible later in the week along the far north coast. High pressure will continue to promote warm interior temperatures, though weakening wind through the week will most likely encourage a stronger but shallower marine layer near shore. /JHW

AVIATION...(07/06z TAFS)

MVFR and IFR ceilings will be possible (30% chance) over Humboldt Bay/Eel delta and KACV tonight through Saturday morning. Satellite imagery showed low cloud amassing over the Eel delta and southern Humboldt Bay Friday evening. Mesoscale models have these clouds dissipating or pushing offshore overnight as a thermal trough builds and northeast- easterly flow strengthens. Some low clouds may meander in and out of KACV into early Sat. Otherwise, VFR conditions are expected to prevail through Saturday. Gusty northerly winds are expected again on Sat, primarily for KCEC. Mesoscale models are starting to converge on low ceilings and vsby obscuration for coastal aerodromes Sat night. Detail are scant at the moment.

MARINE

Marine conditions will remain hazardous for small craft through this weekend as steep northerly waves combine with short period NW swell. Gale force northerlies have abated except for the southern outer waters and near Cape Mendocino where gale gusts to 35 kt are forecast to continue into early next week. Strong to moderate breezes with large steep northerly waves are forecast to continue for much of the waters through the weekend as a thermal trough meanders near the coast. Widespread northerly gales and near storm gusts are expected early next week after the passage of a front.
