Area Forecast Discussion . UPDATE National Weather Service Portland OR 836 AM PDT Tue Oct 27 2020

Updated short term discussion

SYNOPSIS. High pressure will remain over the Pacific Northwest through the middle of this week bringing dry weather and slowly warming temperatures. A weak cold front at the end of the week brings the next chance for rain, but a quick return to dry weather over the weekend appears likely.

UPDATE TO SHORT TERM. Radar observations this morning show light radar returns moving across the south WA coast and approaching the far north OR coast, with light drizzle already being observed around Grays Harbor via CWOP stations and webcams. Forecast NAM BUFR soundings over the next 24 hours at Astoria show a saturated layer that is deep enough to support light drizzle with the presence of weak rising motion. Therefore, a slight chance of light drizzle has been included in the forecast for today through Wednesday morning along the south WA and far north OR coast. In addition, minor tweaks were made to the sky and temperature forecast to better match observations. -TK

SHORT TERM. Today through Thursday . Satellite images early this morning showed marine stratus slowly spreading into the south Washington and far north Oregon coastal areas with a weak northwest onshore flow. As clouds slowly spread further southeast this morning expect the marine clouds to reach into the lower Columbia Valley and further down the north Oregon coastline this morning. Over the next couple of days models suggest low level moisture spreading further south and inland, to include much of the Willamette Valley Wednesday and Thursday morning. Subsidence from the upper ridge shifting inland

will generally keep the moisture confined to a shallow layer in the low levels. Expect some retreat in the low clouds back to coastal areas during the afternoon hours. Beyond the marine cloud considerations, the only other notable change over the next few days is a slow moderation in temperatures back closer to normal due primarily to subsidence warming.

LONG TERM. Thursday night through Monday . 00Z operational models and EC ensemble mean all continue to indicate a shortwave trough moving across the region Friday, dragging a weak cold front south into the region. The front returns a chance for rain to the region Friday, at least across the northern portions of the forecast area. Ensembles suggest this is just a one and done system though, as there is good agreement in the upper ridge rebuilding over the Pacific Northwest over the weekend for a return to dry weather with a continuation of seasonable temperatures. Confidence in the upper ridge continuing into Monday begins to wane some, so will allow for a slight chance of showers in the north coastal region on Monday, but leave the rest of the area dry.

AVIATION. Low pressure over Puget Sound will swing an MVFR ceiling over the northern coast through the night. KAST is already seeing ceilings around 2800 ft. This stratus will likely continue moving south along the coast, reaching KONP early Tuesday morning. Possibility of stratus moving up the Columbia River and into the Portland metro area around 10Z Wednesday. Ceilings will likely stay in low end VFR with some scattered MVFR for the northern Willamette Valley. Stratus will likely push south of KSLE and approach KEUG around 12Z.

For detailed regional Pac NW weather information, go online to: http://weather.gov/zse

KPDX AND APPROACHES . VFR to continue for most of the night. Stratus will move in bringing a chance of ceilings dropping down to around 2000 ft around 10Z Wednesday. -BPhillips

MARINE. High pressure offshore will maintain northerly winds across the waters over the next several days, with the strongest winds expected over the coastal waters south of Cascade Head. Seas will stay in the 3 to 6 ft range, with the highest seas well offshore. Do not expect much change in this pattern through early Thursday.

A front will approach the region later Thursday and shift across the coastal waters Thursday night. This will bring the return of light to moderate southerly winds to the waters on Friday, sustained around 15 to 20 kt. Seas will see a bump upward, but will most likely peak between 6 and 9 ft Friday night. Seas and winds should east this weekend. -BPhillips/TK

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
