DISCUSSION

/Issued 307 AM PDT Mon Mar 9 2026/

Onshore flow has pushed plenty of marine moisture inland this morning, with cloud banked up against the western slopes of the Cascades and the northern slopes of the Siskiyous. The extensive low level cloudiness has prevented fog formation for most areas, but we can not rule out some localized fog where skies remain mostly clear. Some light rain showers have also accompanied this marine push, but has been very light. that fall can provide enough mixing to limit fog development as well.

A semi-zonal flow pattern will guide moisture to the Pacific coast through much of the forecast period, although much of the activity is expected to stay north of the area, where a front will become stall out for much of the week. With our forecast area remaining south of the main belt of moisture flow, most rain will stay to our north as well. With a lack of upper level support, any showers that do develop will be a result of topographic lift, mainly along the coast, over coastal ranges, and along the Cascades.

Also, a tight pressure gradient between a low pressure system in the Gulf of Alaska and the Pacific ridge will combine with stronger mid-level winds to allow for breezy to gusty winds over area terrain and across the East Side in the afternoons and evenings, especially Wednesday and Thursday.

Otherwise, weather conditions will be mostly quiet, with a steady warming trend through the week.

AVIATION...08/18Z TAFs

Lots of VFR ceilings today around 3500 to 4000 feet with some areas along the coast briefly reporting MVFR ceilings. Otherwise, look for plenty of cumulus build up this afternoon as cooler moist air moves in over land and this mid March sun. We should see more VFR ceilings tonight.

MARINE...Updated 1130 AM PDT Monday, March 9, 2026

Advisory level north winds and steep, choppy seas are expected south of Port Orford tonight with lighter winds and lower seas to the north. Slightly stronger north winds south of Gold Beach this afternoon and evening could bring very steep, hazardous seas. Wind wave dominated seas transition to steep west- northwest swell on Tuesday, followed by increased south winds Wednesday into Thursday.
