Area Forecast Discussion National Weather Service Portland OR 243 AM PST Sun Dec 8 2019

SYNOPSIS. Cloudy with areas of fog today. This weeks weather resembles a dishwasher, with alternating wet and dry cycles. Dry on Mon, then a front brings precipitation across region on Tue. Brief break Tue night into Wed, then another front will bring more rain and mountains snow to the region later Wed and Thu. The unsettled weather continuing into next weekend.

SHORT TERM. Today through Tuesday..Decent rainfall across the region in past 36 hours. The low that was responsible for this rainfall is now over the Great Basin. Now, have drier northerly flow over the region, with most of the mid and higher clouds shifting east of the Cascades. Will keep minor chance of showers over the Cascades, mainly south of Mount Jefferson, as still some minor lifting over that region.

But, the lower atmosphere, say below 5000 ft, remains rather moist. With the stable air mass in place, this has led to widespread stratus and areas of fog. Will see the fog gradually thin, but with lack of much low level flow, will take until early to mid afternoon before see much in way of clouds breaking apart. But, with 2 am temperatures in the mid 40s, seems reasonable will see afternoon highs easily get into the lower 50s with any sunshine.

Generally dry weather tonight through Mon night as upper high pres ridge offshore shifts to the Pac NW. Will see areas of fog reform tonight, and again Mon night. Temperatures back down into the 30s, so will also have spots of frost each night, especially inland. Offshore will gradually increase later Mon and Mon night, but appears this only will help areas to fog free in and around the Columbia River Gorge.

Next system will approach the region on Tue. With the main low well north of Vancouver Island, and another off the north Calif coast. This will continue the stretching of the front as it approaches the Pac NW. So, the front will continue weakening as it arrives, with spotty rain or showers for our areas on Tue. /Rockey

LONG TERM. Tuesday night through Saturday . Another active pattern is in store as another broad low advances towards the area from the Gulf of Alaska later next week. Before that low reaches the area, a shortwave trough and associated front will move over northwest Oregon/southwest Washington Tue night. The front will cause a southerly wind shift which will bring warmer air up from the south keeping temperatures in the 40s to 50s with overcast skies. Precipitation, mainly as rain, will fall Wed afternoon into the evening with increased chances along the coast. Thur will be the brief lull between this frontal passage and the onset of the broad low. At this time, there is a lack of model consistency in the low position and intensity. While all models are depicting a fairly energetic system, models have struggled to create a well defined low center and there is a wide output spread between models and their different runs;thus after Thur, there is less confidence. /Muessle

AVIATION. Lots of low level moisture and stable conditions for widespread IFR and LIFR cigs and/or visibilities. There will be little in the way of mixing today with light winds in the low to mid levels. Also upper heights are building resulting in the subsidence inversion strengthening. Will probably have IFR or LIFR conditions through at least 20Z then may see low MVFR around 00Z Mon and possibly low VFR in spots after 00Z Mon based on model consensus forecast. Conditions will likely lower to IFR again by 06Z if not sooner.

KPDX AND APPROACHES . IFR cigs continue early this morning, but visibilities remain above 6SM at KVUO, KPDX & KTTD. This may be due to light easterly flow from the Gorge, but it is very weak so conditions may worsen this morning. Because of the uncertainty of any change in visibility will keep a persistence forecast for the short term. IFR likely through 20Z then low MVFR near 00Z Mon. But NAM and GFS bufr soundings show VFR is possible 00Z to 06Z Mon then back to IFR. /mh

MARINE. A weak high pressure ridge will build over the waters today then shift east Mon. A series of weakening fronts will affect the waters Tue through Thu, but be strong enough to bring Small Craft Advisory winds and seas. High pressure tries to regain control over the waters late in the week but some models still show weak fronts approaching the waters.

Seas hovering around 6 ft through Mon but increase with the Tue front. A large low, stemming from the Gulf of Alaska, could bring seas up to 16 ft or so with periods around 18 seconds later Wed and Thu. /mh

PQR WATCHES/WARNINGS/ADVISORIES. OR . Air Stagnation Advisory until noon Tuesday for inland areas below 1500 feet.

WA . Air Stagnation Advisory until noon Tuesday for inland areas below 1500 feet.

PZ . None.
