Area Forecast Discussion . UPDATE National Weather Service Portland OR 820 PM PST Sat Dec 14 2019

Updated aviation discussion.

SYNOPSIS. Northwest flow aloft will remain over the area through Sunday. High pressure builds offshore Sunday night and gradually shifts toward the coast Monday. Offshore low-level flow strengthens Monday night and Tuesday. The high pressure ridge shifts east of the Cascades by Tuesday afternoon. A more progressive and wetter pattern is expected for the latter half of next week.

SHORT TERM. Tonight through Tuesday . Early afternoon water vapor imagery showed an upper level trough near 45N 128W. The associated surface trough was near 125W at 21Z. Infra-red and visible imagery revealed a surface low circulation about 75 to 100 nm west of K6S2. Precipitation early this afternoon was fairly scattered and light. KRTX dual-pol doppler radar showed the strongest returns in the Columbia River Gorge between KTTD and KCZK. Models do suggest some isentropic lift along the 300K surface this afternoon through the evening as the trough moves inland. Latest models take the brunt of the dynamics toward southwest Oregon and northern California, but some of the higher res models continue to hint at a deformation band-type feature lingering over the north part of the CWA into the evening. Opted to remove the mention of thunderstorms over the coastal waters west and south of Newport as the 12Z HREF showed minimal to no probability on its 4-hr product. The SPC calibrated thunderstorm probability guidance showed the highest threat through 06Z Sun over the southern Oregon and northern California waters.

Model time-height sections and the Hi-Res ARW boundary layer condensation vapor pressure graphics indicate ample low level moisture and stability tonight through Sun morning, which will be highly favorable for fog and stratus across much the interior lowlands. The 12Z models show a building upper level ridge along 130W Sun. However, an over-running pattern will likely result in considerable cloud cover Sun with the possibility of spotty light rain or areas of drizzle. A few of the SREF members for KPDX show some light QPF tonight and Sun. Several GEFS members, including the operational run, indicate some light precip into Mon, even though the ridge eventually drifts inside 125W by Mon. The ridge continues to amplify Mon through Tue due to a deepening upstream upper level trough. Light offshore low-level flow is expected to develop through the Gorge late Mon, but strengthen Mon night and Tue. The 18Z NAM has a -7 to -8 KTTD-KDLS gradient 12Z Tue. Typically, models tend to be 1-2 mb too low with the peak gradient. Thus, would not be surprised to have 60-80 mph wind gusts at Crown Point and Corbett, with the strongest gusts at Crown Point. Air quality will be another factor that will need some consideration during the Mon-Tue time frame. Weishaar

LONG TERM. Tuesday night through Saturday . The offshore pattern continues Tue night through Wed, but the synoptic scale details for that time period are a little muddled. The operational GFS shows a compact closed 995 mb low near 43N 126W 12Z Wed. This appears to be in the minority of solutions as several individual members show a much weaker closed low, or more of an open wave. The operational ECMWF barely shows any surface reflection, with the majority of its ensemble members showing around a 1000 mb low favoring 45N 125W. In any event, with offshore low-level flow continuing through the Gorge have gone slightly lower on POPS than the NBM. Models are in decent agreement showing a much more progressive and wetter pattern beginning Wed afternoon or Wed night. The GEFS shows precipitation ramping up Wed night in a majority of its members. However, the Relative Measure of Predictability valid 12Z Thu is rather low, suggesting below-average forecast confidence.

A particular forecast challenge Wed night and Thu will be the potential for freezing precip in the Central Gorge and Upper Hood River Valley. Have not included it in the grids, but this will be something future shifts will need to evaluate. Above-average confidence exists in the Thu-Fri time frame that an atmospheric river will set up somewhere off the Oregon coast. The operational ECWMF and GFS favor southwest Oregon and northern California, as has been the case for the past couple of events. Most GEFS members are showing .50 to 1.0 inches of precip for KEUG and KPDX in the Thu-Fri night time frame. ECWMF ensembles suggest QPF totals in excess of 2 inches through Fri for the valley and up to 4 inches along the central coast. Much larger discrepancies can be seen in the operational runs Fri-Sat. The GFS maintains the atmospheric river over the forecast area, while the ECMWF keeps the bulk of it offshore and lifts it more north as an upper level trough digs on the back side. All in all, the end of the extended period looks wet with snow levels well above the Cascade passes. Weishaar

AVIATION. Fog is beginning to build in at KHIO and along the coast. VFR cigs through the Willamette Valley will quickly drop to MVFR later Sat night as the fog becomes more widespread. Webcams already show MIFG developing around KPDX and the Willamette Valley. Due to very few mixing features, the fog will be challenging to erode. Because of this, expect fog to remain through around 19Z Sun. At this point, a wind shift to the west is expected after 22Z Sun, increasing winds from near 2 kt to 5-6 kt. Scattered showers remain Sat night but are diminishing through the night. Another chance for fog redevelopment occurs after 04Z Mon as high pressure aloft builds in and winds again become light and variable.

KPDX AND APPROACHES . While VFR cigs are present, a scattered deck around 700 ft AGL should quickly develop to a stratus layer. Fog is expected to develop late Sat night as the dewpoint depression decreases. After 19Z, all fog should be gone and low VFR cigs will return. Showers should be limited to none through Sun. -Muessle

MARINE. Seas have been slow to come down today, as Buoys 46029 and 46050 were still reporting seas 11-13 ft as of 2 PM this afternoon. Expect a slow downward trend to continue this evening, with seas likely subsiding to less than 10 ft by midnight or perhaps a couple hours sooner.

Otherwise, we have weak low pressure near the SW corner of our outer waters, moving SE toward the southern Oregon coast. Winds will likely remain fairly light to the north of the low, which should allow fairly benign winds to go on through tonight and Sunday. Southeast winds will increase Sun night and early Mon as a warm front lifts NE across the waters. Winds appear borderline for an SCA Sun night/Mon, then should increase further as stronger low pressure and its associated frontal system approach the coast later Tue or Wed. Models are all over the place with the handling of this system, with the 12z GFS and NAM suggesting a closed low on the order of 995 mb making landfall somewhere along the Oregon Coast, while the 12z ECMWF and GEM take the bulk of this energy to our south. For now, our forecast reflects increasing south winds and W-SW swell mid- to late-week, with gusts approaching Gale Force at times as fronts pass through. -Weagle
