Synopsis for the southern washington and northern oregon coast - An upper trough grazes the region to the northeast today with winds staying out of the north to northwest. Headed through the rest of the week a ridge of high pressure builds over the eastern pacific before shifting overhead this weekend. As a result rather benign summer-like conditions are expected across the waters.

Area Forecast Discussion...UPDATED National Weather Service Portland OR 1023 AM PDT Tue Apr 16 2024

SYNOPSIS
Onshore flow continues today, along with a few light showers. But, high pressure will build over the region later today into tonight, with clearing skies. Will be cool tonight, and with light winds, will see rather chilly night with areas of frost. After a cool start, a mild Wednesday is on tap. High pressure remains over the region for later this week, with mild temperatures and even a bit of offshore winds for Thu and Fri. Clouds and cooler weather with return of onshore flow expected for next weekend.

SHORT TERM
(TODAY through WEDNESDAY)...
Westerly flow aloft, with moderate onshore low level flow remains intact across the region, as evident by the extensive clouds. A weak upper disturbance in the flow will maintain scattered light showers over the area today, though these mostly over the higher terrain and along the coast. Interior lowlands still being somewhat rain-shadowed (thanks to the westerly flow aloft). As such, any shower would be rather hit-n-miss, with not much rainfall expected.

Overall, today will be similar to yesterday, with plenty of clouds.
Will see bit more in way of breaks in the clouds, but will likely not be until later this afternoon (such as across Lane County) into this evening (areas around Portland and northward) before see any big clearing. As such, still on cool side, with highs 55 to 60.

High pressure offshore will build inland tonight, with clearing skies through this evening. Winds will be light, and with the clearing, will see temperatures drop back into the 30s and lower 40s. Air mass remains cool, and think high potential that many areas will see overnight lows in the 30s, with warmest along the coast. Do think will see temperatures in the upper 20s to lower 30s (sub-freezing)
for many higher locations, as well as the lowlands of the Cascades foothills, Hood River Valley, and in the Willamette Valley south of Corvallis-Albany line, including Eugene. As such, will expand Freeze Warning for those areas. Rest of the area will be cool, but think will just be above freezing. Will cover that area with Frost Advisory. Anyone with outdoor vegetation that is sensitive to cold temperatures should bring their plants indoors if possible, or take other appropriate actions to prevent freeze or frost damage.

After a cool start on Wednesday, should be a rather pleasant day, with highs warming into the mid and upper 50s along the coast, and lower to middle 60s across interior lowlands east of the Coast Range and Willapa Hills. /Rockey

LONG TERM
(THURSDAY THROUGH SUNDAY)...WPC 500 mb cluster analysis indicates that ensembles are in agreement that upper level ridging will continue building over the eastern Pacific and shift east to just off the West Coast Thursday into Friday. At the surface, high pressure strengthens off the coast with a thermal trough building north from California into western Oregon. Due to this, sunny skies and a warming trend will continue across NW Oregon and SW Washington. Inland valley temperatures will inch towards the 70s once again with NBM indicating 55-75% of temperatures exceeding 70 degrees on Thursday and a 70-85% probably of the same on Friday.
This pattern will also result in increased surface pressure gradients over the Cascades and Columbia River Valley, producing increased offshore (easterly) winds for areas near the Columbia River and Cascades, strongest through the Columbia River Gorge. NBM indicates roughly 50-70% probability of wind gusts exceeding 30 mph Thursday and Friday for the Cascades and locations north of Salem.
Additionally, NBM indicates a 60-80% probability for wind gusts to exceed 45 mph for the Columbia River Gorge Friday.

Beyond Friday, ensembles are still uncertain at the exact pattern.
About 30% of the 500 mb clusters indicate ridging will continue through the weekend, which would allow for warm and dry conditions to continue. About 50% of the clusters indicate ridging will begin to weaken or even become more zonal flow, which would allow temperatures to cool somewhat, potentially back to seasonal normals (low 60s for inland locations, upper 50s for the coast). The other 20% or so of the clusters indicate weak troughing will impact the region, bringing near to below normal temperatures and light showers. No matter which solution winds up occurring, no impactful weather is expected in the extended period. /HEC

AVIATION
Expect predominately VFR conditions to continue with widespread mid and high level clouds gradually decreasing through the TAF period, with clearer skies by tonight into Wednesday morning. North to northwest winds at all locations with gusts up to 20 knots along the coast through at least 00Z before decreasing afterwards. Otherwise, winds generally remain 5-10 knots or less. Clear skies along with near to below freezing temperatures will result in the possibility for frost build up on exposed and elevated surfaces. Not expecting significant build up with these conditions.

PDX AND APPROACHES...Expect predominately VFR conditions .
Northwest winds around 5-10 kt, strongest during afternoon and early evening hours. Clear skies along with near to below freezing temperatures will result in the possibility for frost build up on exposed and elevated surfaces. Not expecting significant build up with these conditions. /42

MARINE
Today an upper-level trough grazes the region to the northeast and while impacts remain fairly minor overall, northerly winds are expected to increase in the afternoon with gusts reaching up to 25 kt. Thus, a Small Craft Advisory was issued for all waters starting afternoon and continuing into the evening. On Wednesday and Thursday as the upper-level trough progresses eastward and a ridge of high pressure amplifies over the eastern Pacific winds increase further out of the north with the NBM projecting a 75-95% chance for wind gusts to once again meet Small Craft Advisory criteria for the inner and outer waters generally around and south of Cape Falcon each day. Then late week into the weekend the axis of the upper- ridge moves overhead allowing winds to turn more offshore while seas sit around 4 to 6 feet at 13 to 15 seconds. -Schuldt/42
