Synopsis for the northern and central washington coastal and inland waters..A surface ridge remains centered east of the cascades with low pressure offshore producing weak offshore flow. The ridge will weaken through Wednesday for light winds across area waters. A weak frontal system will arrive on Thursday followed by a more vigorous system on Friday. Areas of fog are expected Tuesday and Wednesday morning over the waters.

00Z TAFs..Messy conditions continue due to stratus and fog, bringing a mix of MVFR to LIFR almost all sites. Look for widespread CIGs to drop back below 3k feet tonight all sites.
Dense FZFG expected ALW tonight, bringing conditions back down to 1/2 mile or less. Sites PDT/PSC/BDN/RDM expected to see CIGs back down to 500 feet or less with BR, but currently keeping direct FG impacts limited, though there always remains the risk the stratus deck could drop down and cause lowered VIS. Expected stratus deck to stay around 1-2k feet for both DLS/YKM with no FG currently forecast. Winds less than 10kts all sites. Goatley/87

SHORT TERM
Tonight through Thursday night
The main concerns during the short term will be fog/freezing fog with areas of dense fog, stagnant air conditions under strong valley and basin inversions, and winds in the southern Grande Ronde Valley near Ladd and Pyles Canyon. The axis of an upper ridge is now shifting to the east of the forecast area, with the flow aloft becoming south to southwest behind the ridge axis. At this same time, an upper low pressure system off the coast is moving to the south- southeast, and will move into California, as it weakens and becomes an open trough. The upper low/trough will push the ridge to the east. The deterministic models and ensembles are in good agreement with the evolution of the synoptic pattern over the next couple of days.
For tonight, a freezing fog advisory will remain in effect until 4 PM for the Foothills of the northern Blue Mountains of OR and WA, as well as central and north central OR. The fog has lifted some in most areas, however there are still pockets of dense fog between Pendleton and Walla Walla, and between Redmond and northern Wasco and Sherman Counties as shown on web cams. May need to extend the Freezing Fog Advisory into tonight as the strong inversions are likely to not mix out. Confidence in freezing fog, with areas of dense fog is high (90-100%).
With the continuation of the strong inversions and little mixing, the accumulation of pollutants will continue over most of central to northeast OR and southeast WA. As such, an Air Stagnation Advisory will also remain in effect tonight through at least 11 AM Thursday morning. Confidence in stagnant conditions continuing is also high (90-100%).
Lastly, winds at the base of Ladd and Pyles Canyon are likely to continue gust to advisory level wind gusts through late this afternoon and early evening. However, they are expected to diminish by later this evening and overnight. Pressure gradients between Baker City and Meacham are still around 5 to 6 mb (the rule of thumb threshold for a Wind Advisory based on the pressure gradients is a difference of 5 mb). There is still a thermal gradient between the Baker Valley and the Grande Ronde Valley as well. However it has weakened, as temperatures have warmed up such that the temperature difference is not as great between the two valleys. The temperatures in the Baker Valley are still colder than the Grande Ronde Valley though with a difference between Baker City and La Grande being 39 at Baker City and 41 at La Grande. As night time cooling begins, these thermal gradients are expected to increase again. However that will be counter- affected by a weakening pressure gradient. Conditions to support a Wind Advisory will likely continue into early this evening, and then decrease by later this evening. Confidence of Wind Advisory winds continuing into this evening are moderate to high (70-80%).
The lower confidence is a result of the uncertainty due to opposing differences between the pressure gradients and thermal gradients, with one counter-affecting the other.
Temperatures will be colder during the day in areas covered by fog and low stratus clouds, and warmer where skies are mostly clear. However, at night, temperatures will not cool as much under the fog and low stratus as much as areas with clear skies. Winds will be light across the forecast area (except the southern Grande Ronde Valley) to allow temperatures to be as cold as the past couple of nights. Lows tonight will be in the mid to upper 20s in the fog/stratus covered areas, and teens to lower 20s in areas with clear skies. The exception will be southern and southeast Deschutes County, where lows could drop to the lower to mid teens. Daytime highs on Thursday will be in the upper 20s to lower 30s in the lower elevations under the fog and stratus layer, and 30s and 40s in the mountains. In central OR and the Ochoco- John Day Highlands, high temperatures will be warmer with readings in the mid 40s to around 50 (warmest areas in the valleys and river bottoms, such as the John Day River Basin.
Winds will be light in most areas through the short term period, (except for the southern Grande Ronde Valley early this evening).
However winds will become locally breezy in central OR (mainly on the higher elevation ridge tops) and over the Cascades by Thursday afternoon. 88
LONG TERM
Friday through Tuesday
The long term remains active thanks to a complete pattern change in the form of several systems making their way across the region, bringing multiple rounds of mountain snow, lower elevation mixed precipitation becoming pure rainfall, increasing temperatures, and breezy winds.
The period begins as a trough is already passing over the region, with precipitation ongoing. Lower elevations are expected to see a shadowing effect, but with temperatures and snow levels still on the lower side, even the these elevations may see some light accumulating snow with any precip that can occur. Snow levels will be on the rise however thanks to warmer air masses with these systems, bringing all rainfall as temperatures rise. There is a chance though that colder air may get trapped at the surface initially Friday morning with warmer air aloft, and a mixed phase of precipitation that includes frozen precipitation could occur.
Currently, would estimate that this would be a short lived occurrence as temperatures continue to rise through the weekend, but the risk is there nonetheless and could lead to slick surfaces.
Speaking of the weekend, northwesterly flow aloft and multiple systems progressing across continue to bring chances of mountain snow and lower elevation rain, but rain levels continue to rise as temperatures increase. Meanwhile, the tightened pressure gradients and systems should produce breezy winds. The NBM currently highlights a 20-70% chance of wind gusts exceeding or equal to 45 mph, which would be strong enough to warrant wind advisories. By Sunday, snow levels will reach above 6k feet, confining snow to the highest elevations. This is where we will transition to our next expected hazard, which will be hydrological concerns as rainfall continues into next week while moving into areas that previously experienced snow. A transitory ridge moves across on Monday, bringing a westerly flow before a southwesterly flow then takes over on the backside of the ridge on Tuesday. Snow levels further rise, and with rain continuing to move across the mountains, snowpack that accrued over the weekend will begin to melt and river rises are likely. It's currently too early to gauge if there will be notable downstream consequences, but it wouldn't be surprising to have at least some noteworthy rises if not some rivers and streams approaching bankfull depending on how much QPF occurs, as well as how cold nearby ground temperatures are and if runoff occurs.
Analysis of the ensembles and the their clusters indicates good agreement with the above forecast. Analyzing the ensemble clusters shows some discrepancies in the strength of the transitory ridge which could impact early week QPF, but clusters agree on the progression of the ridge which lends to moderate to high confidence overall (60-70%).
