Area Forecast Discussion National Weather Service Portland OR 311 PM PST Thu Jan 23 2020

SYNOPSIS. A cold front will slowly move across SW Washington and NW Oregon this evening resulting in periods of heavy rain. Then showery later tonight and Fri, though showers will be decreasing Fri afternoon. Unsettled weather continues into next week resulting in more valley rain and mountain snow. Temperatures remain rather mild, with snow levels remaining mostly above the major passes of the Cascades through the weekend.

SHORT TERM. Tonight through Sunday . Satellite and radar imagery suggests that the cold front is just offshore this afternoon, with several waves of moisture moving along the front. This will result in periods of heavy rain across portions of the North Coast Range and Willapa Hills through this evening as the front slowly creeps east. Given that these waves continue to be aimed at the Willapa Hills would not be surprised if they received another one to two inches. This has the potential to push the Grays River over 16 ft if the front stalls out. The heavy rain over the next several hours will also have the potential to cause some flooding along other rivers draining off the North Coast Range and Willapa Hills. A flood watch remains in effect through this evening for the North Coast and Coast Range and the South Washington Coast and Willapa Hills, with the Wilson River near Tillamook and the Nehalem River near Foss at greatest threat.

As the front moves across the forecast area expect a period of breezy southerly winds this evening with gusts to 40 mph possible along the beaches and headlands and gusts to 30 mph possible in the interior lowlands. Based on the latest trends expect the front to move east of the Cascades by midnight tonight. Rain will continue to increase in the interior this afternoon and evening, with another 0.25 to 0.50 inches likely at most lowland locations. The Cascades will generally receive another 0.50 to 1.0 inches tonight, with the highest amounts over the South Washington Cascades. The good news is that snow levels generally remain above 6000 ft tonight, but will lower to near pass level Friday morning. The South Washington Cascades could see another 1 to 3 inches Friday morning while the Oregon Cascades should only see up to an inch or so.

Rain will transition to showers tonight with mild south to southwest flow. Precipitation chances will gradually decrease on Friday, with a mix of sun and clouds along with some scattered showers. Another area of low pressure will move across the region to our north Friday night into Saturday. At this point this system doesn't look to be as wet as today's front, but most of the area getting another 0.20 to 0.40 inches of rain, with up to an inch in the higher terrain. Snow levels will be rising so not expecting a lot of accumulations in the Cascades below 7000 ft. Guidance then shows another area of low pressure moving across the area Saturday night into Sunday which will result in more valley rain and high Cascade snow. /64

LONG TERM. Sunday night through Wednesday . A chaotic long term is expected with a series of shortwave disturbances bringing persistent valley rain and mountain snow through the end of the forecast period. Ensemble guidance agrees that a weak shortwave will bring heavy rain to the Coast and snow across the Cascades as it tracks across the waters Sunday night into Monday. There is little confidence after Monday afternoon as sporadic shortwaves create for challenging solutions in winds and temperature between the models. There could be a short period Tuesday evening where the rain will lighten but another round of heavy precipitation is expected on Wednesday. -BPhillips

AVIATION. Inland locations can expect predominately VFR conditions with occasional MVFR cigs especially north of KSLE. Southerly winds through the Willamette Valley are expected to keep the area well mixed, which will hamper the development of visibility restrictions. Inland locations are expected to develop MVFR conditions starting around 00Z Friday. Coastal locations are expected to maintain IFR/LIFR conditions for areas around KONP and MVFR conditions for areas around KAST. Coastal locations are expected to maintain these conditions through the forecast period. Precipitation will persist over the next 24 hours as a cold front approaches the area.

Gusty conditions will continue to persist along the coast through the night. Surface winds will maintain a southerly direction, with winds aloft out of the southwest. Conditions have potential for LLWS, therefore have added LLWS into the TAFs.

Expect general improvement of flight conditions towards MVFR for coastal locations and VFR conditions for inland locations staring around 20Z Friday.

KPDX AND APPROACHES . Mainly VFR conditions through 00Z Friday as a cold front approaches the area bringing MVFR cigs. Expect precipitation over the area for the next 24 hours. Surface winds will maintain a southerly direction, winds aloft are out of the southwest, therefore have added LLWS into the TAFs. /42

MARINE. An active pattern will persist through the next week as a series of fronts stemming from the Pacific move over the waters.

There are several embedded lows within the flow of a broad parent trough, which is located within the Gulf of Alaska. These weak lows are creating several different swell trains, resulting in a very steep and choppy sea state. The westerly swell is the more dominate and will be consistent through next week. In general, heights will be around 12 to 15 ft through Friday. Seas look to subside to 8 to 10 feet during the weekend, will build back towards the mid teens again Sunday and Monday, then subside to 9 to 11 feet starting Tuesday.

The gale warning remains through Thursday night for all waters, but could be replaced by a small craft advisory before 9 PM as winds might subside below 35kt gusts. Confidence remains low at this time as to the timing of when the gale gusts will subside. /42

PQR WATCHES/WARNINGS/ADVISORIES. OR . Flood Watch until 9 PM PST this evening for Coast Range of Northwest Oregon-North Oregon Coast.

WA . Flood Watch until 9 PM PST this evening for South Washington Coast-Willapa Hills.

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.
