SYNOPSIS
Rain will continue to diminish across the south this evening, with scattered showers lingering into Monday morning in the wake of a front. Weather trends drier with mild temperatures for much of the coming week, although a front will bring a chance for light rain late Wednesday into Thursday.

DISCUSSION
Radar imagery shows rain focused along a line extending from the north Oregon Cascades through the south Willamette Valley to near Florence this afternoon as a weakening atmospheric river continues to shift south across the area.
Rain has tapered off to scattered showers across northern portions of the area, allowing earlier Flood Watches to come to end across the Willapa Hills and north Oregon Coast Range as rivers there have crested below flood stage as of early afternoon. Do not anticipate any additional hydro concerns as rain continues to shift south and diminishes in intensity through this evening. A cold front currently extending southwestward from near the south Washington Coast through the Oregon coastal waters will push across the area this evening and bring steadier rain across the south to an end as precipitation fully tapers off to showers tonight in the post frontal environment. Snow levels will lower back towards the passes overnight which could result in a dusting of snow in parts of the High Cascades, but the showery nature of the precipitation and dwindling QPF amounts will preclude any more significant winter weather impacts. Elsewhere, partial clearing tonight combined with moist antecedent low level conditions could produce areas of fog in the interior valleys overnight into Monday morning.

Monday is looking mostly dry with the exception of some lingering shower activity along the Cascades as a weak shortwave trough traverses the region in northwest flow aloft, with most of the area seeing cloudy skies and mild December temps in the low 50s. The drying trend will be re-enforced by a ridge building in on Tuesday, likely yielding a few breaks of sunshine across the region Tuesday afternoon. Dry weather lingers through most of Wednesday before a weak front pushes across the region Wednesday night into Thursday. The majority of ensemble members are depicting at least some QPF with this feature, but amounts look to be limited to around a quarter to a half inch for coastal areas and a tenth or less elsewhere at this time. Wouldn't be surprised if guidance continues to trend drier in the coming days given low level offshore flow that will be in place ahead of the front. Models trend drier again into Friday as WPC ensemble clusters favor a blockier pattern with ridging over the western CONUS and a deep trough over the eastern Pacific. Precipitation chances look to increase next weekend as the trough makes slow progress towards the West Coast. /CB

AVIATION
Widespread IFR and MVFR conditions across the area as the front very slowly makes its way southeast. Winds have shifted west, northwest along the south Washington coast but everywhere else continues to see breezy southerly winds. The heaviest rain has moved south of a line from KONP to K4S2 as the midlevel front moves through. Terminals will continue to see poor conditions through the next 24 hours as a fully saturated boundary layer remains with temperatures cooling in the post frontal air mass.
Breezy southerly winds will transition to weak northerlies behind the front.

*KEUG currently is missing visibility observations between 06Z-15Z. Because of this, visibility forecast is influenced by area observations. *

PDX AND APPROACHES...Mix of IFR and MVFR through the next 24 hours as the cold front slowly approaches the northern Willamette Valley. Breezy southerly winds will transitions to weak northerlies after roughly 06z Mon.

MARINE
Winds and seas continue to diminish across the coastal waters. A Small Craft Advisory remains through 10 PM tonight as seas will likely hover around 10 ft before dropping below overnight. High pressure builds in Monday which will bring a period of much more settled weather through Tuesday. A frontal system will move across the waters late Wednesday bringing sub- Gale conditions before returning to quiet weather late in the week.
