Area Forecast Discussion . UPDATED National Weather Service Portland OR 1103 AM PDT Tue Oct 19 2021

Updated Aviation and Marine Sections

SYNOPSIS. After a brief break in the wet weather today, expect a very active weather pattern to bring valley rain and high mountain snow every 12-24 hours through early next week. A brief burst in wind will be possible late tonight and Wednesday morning with additional stronger bouts of wind possible over the weekend and/or early next week.

SHORT TERM. Today through Friday . Water vapor satellite imagery reveals a shortwave ridge over the Pacific Northwest being shunted eastward as a shortwave trough over the eastern Pacific slides towards the region. Models are in good agreement this shortwave trough will take on a negative tilt as it pushes into the Pacific Northwest tonight. This will spread a band of rain from southwest to northeast across the area this evening/overnight. The fast moving nature of this system will limit rainfall totals. However, strong mid level forcing and modest low level convergence along the front will likely bring a burst of more intense rain, and perhaps more notably, some gusty winds. Several high resolution models suggest wind gusts between 30-45 mph will surface along portions of the coast and in at least isolated spots in the Willamette Valley around daybreak as winds aloft mix down with frontal passage and/or with convective elements embedded along the front.

It should be noted that the operational GFS is an outlier within the GEFS system, but does bear some resemblance to many members within the EPS system and a few members in the CMCE system, all of which suggest a surface low pressure between 995-1003mb forming along the front off the Oregon coast as it shifts northeastward towards the region. This doesn't seem unreasonable given the pattern, but uncertainty in the magnitude of this embedded wave along the front does bring some uncertainty in whether or not stronger winds will be possible, particularly for the coast. The operational GFS's worst case scenario depiction would likely only result in marginal to low end High Wind Warning gusts of ~60 mph along the most exposed beaches and headlands from approximately Tillamook northward late tonight into early Wednesday morning. Many of the slightly weaker low pressure scenarios depicted by the EPS and CMCE members would likely produce sub-warning wind gusts. As a result, opted to increase winds along the coast to account for these windier solutions, but given most ensemble guidance suggests just a breezy period, will hold off on any wind highlights at this point.

Meanwhile, models are in good agreement a shortwave trough racing eastward across the Aleutian Islands early this morning will interact with tropical moisture and result in one of the more impressive bomb-cyclogenesis events to occur in recent history off the Pacific Northwest coast Wednesday. Fortunately, the rapidly deepening low pressure will be far enough removed from OR/WA that the worst of the wind hazards accompanying it will remain well offshore Wednesday night into Thursday. In fact, ensemble guidance continues to support the idea that between the attendant front weakening as it approaches the region and pressure gradient forces remaining oriented strongly offshore, winds should remain well below High Wind criteria along our coastline. Nonetheless, this storm system will likely bring a solid shot of rain to the region late Thursday and it will generate a swell that will result in a sneaker wave threat along our coast Friday. Expect cooler temperatures Friday with precipitation turning more showery in nature. /Neuman

LONG TERM. Friday night through Monday . There continues to be above average agreement in the general weather pattern, which will feature a strong zonally oriented jet racing eastward across the Pacific Ocean towards northern California and southern Oregon. This will result in an extended stretch of particularly active weather across the Pacific Northwest that will feature below average temperatures with periods of rain/showers every 12-24 hours. NBM PoPs support this idea and generally range in the 80-95% range in each 12 hour period throughout the extended forecast. The first storm system of the extended forecast period will likely affect the region Friday night. A front should spread east-southeastward across the region Friday night and result in a solid shot of rain areawide with some potential for wind headlines along the coast depending on how the parent low pressure strengthens. Confidence in details beyond this time dwindles rapidly, though.

An operational model or two over the past day and a few more of the 00z ensemble members than 24 hours ago suggest a cyclogenesis event occurring in the vicinity of our coastal waters over the weekend or early next week. A few of these scenarios would almost certainly result in high winds along our coast and in the Willamette Valley. Nonetheless, it still appears to be a rather small percentage (~10%) of the available ensemble guidance, but bears watching given the pattern. /Neuman

AVIATION. 18Z TAFs: Generally VFR with high clouds over the region late this morning. However, as of 1730Z there were still some pockets of LIFR or lower conditions in the central and south Willamette Valley. The 12Z HREF ensemble mean cloud cover guidance and model soundings suggest increasing mid-level clouds through the afternoon. The incoming frontal system is expected to elongate and weaken as it approaches the coast this evening. Expect rain to reach the coast between 04Z and 07Z, earliest south of KONP. Rain gradually spreads inland after 07Z, but low- level offshore flow through the Columbia Gorge will delay onset of rainfall closer to 12Z Wed. The front reaches the coast south of KONP around 12Z Wed, but not until 15Z or so along the south Washington and north Oregon coast. Increasing MVFR conditions will be likely for the coastal TAF sites overnight. Expect south wind gusts 25-35kt along the coast associated with the frontal passage. Gusts 20-30kt likely inland between 12Z and 18Z Wed, especially south of a KTMK to KSLE line.

KPDX AND APPROACHES . VFR conditions are expected to continue the evening, with cigs gradually lowering to 100 by 06Z Wed. Rain develops between 07Z and 10Z, but cigs to remain VFR. East wind gusts to 30 kt likely near KTTD and the west end of the Gorge this afternoon through 12Z Wed. Weishaar

MARINE. A strong front will approach the outer waters this afternoon. The latest models show this front elongating/weakening as it moves through the outer waters. The 12Z model guidance maintains the trend of depicting the strongest wind speeds over the outer waters (beyond 20 nm). Will maintain the current gale warnings. Some models show a strong wave on the front early Wed morning, but vary on the strength and timing of this feature. About 25 of 50 ECMWF ensemble members show gusts 40-48 kts at 12Z Wed for buoy 46050. The favored time frame for gale force gusts over the inner waters appears to be between 12Z and 18Z Wed.

A second, potentially stronger, system is forecast to impact the waters Wed night and Thu. Confidence is fairly high gale force gusts will occur over PZZ270 and PZZ275. Less confidence in gale force gusts over the inner zones. The parent low remains well offshore with a majority of the individual ensemble members showing the surface low tracking to the south British Columbia coast Thu. The active pattern continues through the weekend with additional gale force wind periods likely.

Total wave heights will begin to ramp up over the outer waters this afternoon and spread to the inner waters this evening. There will be a substantial south wind wave component, up to 10-12 ft over the far southwest portion of PZZ275, tonight. This will result in combined seas into the upper teens for the outer waters. Wave heights will be several feet lower over the inner zones tonight, but still exceed 10 ft. Seas gradually subside late tonight and Wed. The expected gales Thursday will allow seas to rise into the 15 to 20 ft range with highest seas offshore. Weishaar
