Synopsis for the southern washington and northern oregon coast - High pressure east of the cascades with a thermal trough along the oregon coast continues through Friday afternoon. The thermal trough breaks down as a front approaches the waters tonight and moves through the waters Saturday.

Area Forecast Discussion National Weather Service Portland OR 303 AM PDT Fri Apr 19 2024

SYNOPSIS
High pressure holding steady over the region through tonight, with another mild day on tap, along with breezy east to northeast winds on the west slopes of the Cascades and to some degree, the Coast Range.
Cooler for Saturday, as a front moves across the region. May see spotty light rain as well on Sat into Sat night. Dry and mild again to start next week, but cooler showery weather returns by Wed.

SHORT TERM
(TODAY THROUGH SUNDAY)...Quite a difference this am as compared to 24 hours ago. This due to the offshore flow over the region. Where winds have stayed up, temperatures are still in the upper 40s to mid 50s, such as Portland/Vancouver metro with temperatures still in 50 to 55 as of 2 am. Not a lot of wind, but enough considering most of this warm is due to the downslope of the air mass down the west slopes of the Cascades. Where winds have gone calm, temperatures are in the upper 30s to lower 40s. Similar conditions along the coast, where light east wind is keeping it mild, with much cooler conditions in the windless valleys.

Overall, not much change today as compared to Thursday. Most areas will again rise into the 60s, with lower to middle 70s for many areas. Have boosted todays highs over what NBM (National Blend of Models guidance) has, as NBM is often behind the 8-ball with such offshore patterns. Gradients will pick up again, mostly in response to daytime heating on the west side. Generally, east to northeast winds gusting 15-30 mph in the usual spots (those exposed to east winds) such as along the coast into the Coast Range. Bit stronger with gusts up to 40 mph in the Cascades foothills and perhaps parts of the east Portland/Vancouver metro into the western Columbia Gorge for the afternoon/evening. Winds more north to northeast as move south of Portland towards Salem and Eugene and not as strong with gusts maxing at near 15 mph.

Still expecting a mild wind-reversal along the coast in the afternoon, with east to northeast winds becoming southerly to south of Florence in the afternoon, and as far north as Newport by sunset as the thermal trough shifts inland to sit over the Coast Range. This will allow for cooler ocean air to spread back across the coastal zones at that time. But, offshore flow persists on to the north overnight, such as at Astoria. Likely be one of those afternoons where Newport cools to 59 with light south wind, while Astoria is around 70 with an east wind in the late afternoon.

Changes gradually arrive tonight into Sat, as a front well offshore approaches. Will see offshore flow gradually weaken tonight. Mid and high clouds increasing later tonight into Sat. Models have been slowing the front, and like that trend. Few sprinkles along the coast Sat am, but think main rain arrives along the coast towards noon, with spotty rain or showers spreading further inland in the afternoon. With the bulk the lift with the front staying farther north over Washington, rainfall amounts will vary across the region, with 0.10 to 0.25 inch along the coast/coastal mountains, and 0.02 to 0.10 for the inland areas. With the onshore flow and clouds, will be cooler on Sat, with the 50s along the coast, and upper 50s to lower 60s inland.

High pressure offshore will being building inland on Sunday. This will end the shower potential, with morning clouds giving way to mix of sunshine and clouds. Overall, fairly pleasant day, with temperatures near that expected for mid-April. /Rockey

LONG TERM
(MONDAY THROUGH THURSDAY)....Ensemble guidance points towards another transitory ridge shifting across the region Monday into Tuesday, with dry and mild weather. Will trend temperatures back to the 60s along the coast, and 70s for interior lowlands. But, models area back to bringing another upper trough to the region by mid-week. As such, would see a bit cooler temperatures again, along with increasing potential of showers. /Rockey

AVIATION
VFR but breezy as offshore flow strengthens through this morning. Easterly/northeasterly winds continue today with east winds will strengthen after 15Z Fri as KTTD-KDLS pressure gradients tighten slightly. The strongest winds will be through the Columbia River Gorge and into the Portland Metro Area, where east winds could gust up to 25-30 kt through 00-02Z Sat. Winds ease this evening as the offshore pressure gradient eases.

PDX AND APPROACHES...VFR expected through the TAF period. East winds strengthening after 15-17z Fri to around 18-22 kt with gusts up to 25-30 kt through 00-02z Sat. East winds begin to weaken in the evening to near 10 kt. /mh/Alviz

MARINE
East to northeast winds today as high pressure resides east of the Cascades and a thermal trough over western WA/OR. This pattern breaks down tonight as a Pacific front approaches. Southerly winds increase through the day Saturday as the front moves through the waters, with Small Craft winds and choppy seas likely into Sunday. Seas building to 8 to 12 ft Saturday with the front, then settle to around 8 ft Sunday. /mh
