Area Forecast Discussion National Weather Service Portland OR 247 AM PST Tue Feb 18 2020
SYNOPSIS. High pressure will keep the region dry for today through Friday. But, this will also bring east to northeast winds to the region for next several days. Otherwise, plenty of sunshine, with mild days and chill star-filled nights. Will see rain return to the region this weekend, with lowering snow levels.
SHORT TERM. Today through Thursday . Rather chilly morning across southwest Washington and northwest Oregon, with 3 am temperatures in the lower 30s for most areas, though do have pockets where temperatures have dropped into the upper 20s. Will see plenty of frost across the region this am, so motorists should be ready for a few slick spots, mainly in forested areas and less-traveled rural roadways. Do have areas of low clouds and fog forming across the region, mainly along the major rivers. This fog and low stratus will spread across most areas over next few hours, making for widespread low clouds and fog into this morning.
NOAA satellite imagery showing a well-defined upper trough digging into the northern Rockies, with cool northerly flow aloft over the Pac NW. Surface high pressure just offshore will build inland today, and remain over the interior Pac NW through Thursday. As the high builds inland, will see increasing east to northeast low level flow. Easterly winds will likely gust 15 to 20 mph for most lowlands areas tonight through Thu am, with gusts 25 to 35 mph over the higher terrain. But, expect east winds to gust 35 to 45 mph around the western end of the Columbia Gorge, with higher gusts between Troutdale and Bonneville. This will bring drier air west of the Cascades, with much less in way of fog or stratus for Tue night and Wed night. This pattern will also maintain mild days, with highs in the upper 40s to middle 50s, depending on elevation. Those with an interest on star-gazing will be in for a nice treat, with great star-gazing conditions under clear skies and not much moonlight as the moon that is approaching new moon phase. But, will be a tad chilly, so bundle up if outdoors next few nights. /Rockey
LONG TERM. Thursday night through Monday . Models hint that a weakening front will approach the region late Friday as a shortwave trough slides eastward into British Columbia. At this point, model and ensemble guidance has trended towards a weaker scenario, which more than likely results in the entire CWA remaining dry through Friday. Did hold onto some slight chance to low end chance PoPs for our far northwestern zones on Friday as cannot completely rule out rain yet.
Models and their ensembles remain in good agreement a more consolidated shortwave trough will drop southeastward into the Pacific Northwest late Saturday into Sunday. This storm system appears likely to bring another shot of valley rain and mountain snow during this period. While snow levels will likely begin above the Cascade passes, it appears they will likely lower down into the 1000-2000 ft range by late Sunday. It appears precipitation will likely turn showery late Sunday into Monday with precipitation chances decreasing steadily during this time. /Neuman
AVIATION. VFR conditions will slowly degrade as IFR/LIFR conditions are develop after 12Z Tue throughout the Willamette Valley and KAST. Satellite and ground observations show a well defined line of IFR cigs along the Columbia River and snaking down into the northern and central Willamette Valley. Expect IFR cigs to develop around KEUG and work into the southern and central Willamette Valley. With temperatures are at or near freezing, expect areas of light frost this am. Light offshore low-level flow develops later this am, then strengthens in the afternoon. IFR or lower conditions will gradually improve to VFR later this am, and be gone by 20Z Tuesday.
KPDX AND APPROACHES . IFR conditions will persist through at least 20Z Tuesday. After 20Z look for conditions to improve back to VFR. /42
MARINE. Offshore winds prevails over the waters through today. A thermally-induced low along the north California coast will result in SCA gusts over the PZZ275 and PZZ270. Therefore have issued a small craft advisory for our offshore waters, starting in zone PZZ275 then moving into PZZ270 by Tuesday afternoon. There is the potential for these conditions to impact the near shore waters but at this time guidance mixed on this happening. There is the possibility of isolated 25 kt gusts Tuesday night through Wednesday morning near the coastal terrain gaps.
Winds subside by Wednesday night and will remain generally 10 kt or less through Friday. Wind speeds increase Sat due to an approaching frontal system. Operational runs remain in good agreement showing solid small craft advisory level wind speeds starting Saturday.
Seas will hover around 4 to 6 ft today and remain in that range through the middle of the week. Guidance shows seas building to the mid teens on Saturday. ENP wave guidance suggests seas will get close to 20 ft Sunday. These seas appear to be generated by a ~995 mb low near British Columbia, both the GFS and ECWMF have weakened this low considerably from the previous runs. /42

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
