SYNOPSIS. After high snow levels today, a cooler and active weather pattern will bring periods of valley rain as well as snow in the higher elevations of the Coast Range and Cascades Wednesday through the end of the weekend.

SHORT TERM. Tonight through Thursday . Water vapor satellite imagery this afternoon reveals a weak and low amplitude shortwave ridge over the Pacific Northwest while a shortwave trough drops southward off the California coast and a vort max over the northeast Pacific shifts eastward towards Washington. Visible satellite imagery reveals plenty of low clouds north of Salem this afternoon. These clouds are tied to a weak warm front draped across the region as warm and generally moist air lifts over the top of cool air flowing out of the Columbia River Gorge. This will keep a chance for light rain or drizzle in the forecast across the higher terrain and areas centered around the Gorge and northern Willamette Valley. This area of light rain and drizzle should gradually weaken this evening as south to southwesterly flow increases across the broader region ahead of a weak cold front pushing across southwest Washington and northwest Oregon overnight. This front will lower snow levels from 6000'+ this afternoon to below the passes in the Cascades by daybreak on Wednesday.

Post frontal showers should gradually deepen and intensify later tonight into Wednesday, which will bring accumulating snow to the Cascades. A reinforcing shot of colder air spreading into the region will lower snow levels further and bring even more showers to the region late Wednesday into Thursday. While accumulations will likely not meet advisory strict criteria at the beginning of this event on Wednesday, temperatures dropping below freezing will result in more travel impacts than a few inches of snow would otherwise produce. As a result, opted to do a longer duration advisory to highlight impacts to travel will begin Wednesday across the Cascades and persist into Thursday when snow accumulations will likely be highest in the Cascades.

In addition, with snow levels likely lowering into 1500-2000 ft range, accumulating snow will be possible at the higher passes in the Coast Range, specifically along US26 and OR6. In addition, valleys in the Cascade foothills such as Detroit and Brightwood may also experience some light snow accumulations Wednesday night and Thursday. At this point, think accumulations will generally be marginal for necessitating a Winter Wx Advisory for these zones, but still more time to sort this out. Regardless, this is a pattern that can result in what normally would be just wet roads freezing when skies clear between passing showers. This is most likely to occur across the east slopes of the Coast Range and far western portions of the Willamette Valley Thursday and Friday mornings. /Neuman

LONG TERM. Thursday night through Tuesday . Shortwave ridging will shift southeastward across the area Friday. This should result in showers decreasing across the area and perhaps briefly ending all together before the next more vigorous shortwave trough slides southeastward into the Pacific Northwest. There is a strong signal in the ensemble guidance that this storm system will bring strong winds to the coast late Friday or early Saturday with High Wind Watches/Warnings likely to be issued as the event draws closer. The biggest question remains if gusts will top out in the 60-70 mph range or in the 70-80 mph range across the beaches and headlands. Strong winds may not just be limited to the coast, either, as NBM 4.1 shows very high probabilities of max gusts reaching 40 mph in the Willamette Valley, which is echoed by most EC/GEFS ensemble members. In addition, snow levels appear likely to start off near the Cascade passes before quickly falling back down into the foothills late Saturday into Sunday with upwards of 1-2" of QPF so this appears likely to be a big snow producer for the mountains and Winter Storm Watches/Warnings may be needed. Less than 20-25% of ensemble guidance suggests the front will move slow enough to bring a concern for lower elevation high rain totals that could result in some of the flashier rivers in the Willapa Hills and north Oregon Coast Range reaching minor flood stage.

A cool and showery weather pattern then appears likely to take hold Sunday into early next week across the Pacific Northwest. Snow levels appear likely to once again drop down into the Coast Range and Cascade foothills. There remain some ensemble members that suggest some accumulating snow could reach the valley floor, but these still remain the minority. NBM guidance remains a good middle of the road forecast for now. /Neuman

AVIATION. 00Z TAFs: Satellite continues to show the widespread IFR stratus over the region that has yet to lift this afternoon. Because it has been more stubborn than expected, have allowed conditions to stay reduced throughout much of the coast and from KUAO north in the Willamette Valley. There does appear to be some breaks in the clouds in the north, however even if they do clear it will be challenging to lift conditions to MVFR or higher.

Rain showers will persist through the evening becoming heavier as a cold front advances over the area tonight. This cold front is not overly strong, but it will cause winds to become onshore and pick up in intensity slightly. With the aid of the mixing associated with this weak front, this would be the time that CIGs may lift to MVFR or even low VFR levels. Likely this improvement, if it does occur, wouldn't be until after 18Z Wednesday. Ultimately, there is a lot of uncertainty in the forecast due to the timing of the front, rain, wind and the variability of the ceilings.

KPDX AND APPROACHES . CIGs have yet to lift, and there seem to be very few hints of improvement for the terminal. Likely going to see IFR conditions for the next few hours until winds begin to shift from an easterly flow to a more southerly flow. May see CIGs lift to MVFR, but there is nearly an equal probability that conditions may stay IFR. Decreased visibility expected with mist and rainfall in passing showers. Slight improvement is possible late in the period as winds increase slightly and the weak shortwave passes. Ultimately, not looking at a ton of drastic change in the longer term portion of the forecast. -Muessle

MARINE. What has been more settled conditions will ramp up tomorrow and stay elevated for the next few days. Seas and winds will both slowly build this evening as a weak cold front passes over the area. Likely winds will be the initial shift as they build from the current 10 kt gust 15 kt to around 15 to 20 kt gusts up to 25 kt by late tonight. Then they will build even higher with chances of gusts up to 30 kt in the northern outer waters out past 30 NM. This is a fairly fast moving system, so not expecting winds to hold on too long, and should ease below 25 kt by Wednesday afternoon. However, just as winds begin to ease, seas will build. Seas that once were sitting at around 8 to 10 ft at 10 seconds will increase to 10 to 13 ft at 15 seconds by Thursday morning. In general the northern waters will see the higher wave heights due to an amplified wind wave. Conditions will remain consistent through Friday.

As we near the weekend, much more active weather is expected. A cold front will advance over the area on Thursday which will bring a slight chance for thunder to the south Washington waters and seas will slowly build to around 14 ft at 13 seconds. Models differ quite a bit though with more recent models suggesting slightly lower sea heights than previous runs so will continue to monitor. An even stronger system is possible on Saturday which may bring the chance for near gale force winds through the day. -Muessle
