Area Forecast Discussion National Weather Service Seattle WA 226 PM PDT Sat Oct 23 2021

SYNOPSIS. A strong front will move through Western Washington Sunday morning. A deep low pressure system will approach the area on Sunday and then weaken somewhat and move across Vancouver Island Monday afternoon. Periods of wet blustery weather will occur through next week as additional frontal systems move through the region.

SHORT TERM /TONIGHT THROUGH TUESDAY/. The strong frontal system and rapidly deepening low pressure center seem to be doing what the global models have been advertising. A storm will move through the offshore waters and pull up just short of the coastal waters before it starts to fill and curve toward Vancouver Island Sunday. The front will move through Western Washington Sunday morning, fropa might be as late as early afternoon in the north. Several hours of windy conditions are a good bet despite the low still being offshore- -the mesoscale models have enough wind through the gaps and in the normal windier locations to justify various wind advisories and warnings. Obviously this isn't the sort of storm we worry about for the Seattle metro area because the low center is so far away but even the initial front can have a pretty decent pressure fall/rise couplet, so I'll be surprised if it isn't blustery around Seattle for awhile on Sunday. As far as easterly winds through the Cascade gaps--the Seattle Wenatchee pressure gradient should get up around -10mb, so that falls short of what we might see later in the season when there is often colder air and higher pressure over Eastern Washington. That said, with a frontal passage Sunday morning, there might be winds aloft mixing down though I did not see anything startling in the mesoscale models that might indicate mountain waves surfacing so I'm not too keyed up about that idea.

The surf will build Sunday night and a high surf warning was issued for the coast. And as the low moves ashore Monday over Vancouver Island tide gages from Port Townsend to Cherry Point ought to be two feet above the tide table predictions, so it is a good thing we are not in a king tide cycle (that next occurs Nov 5-9th). Periods of heavy rain will fall in the mountains, but only the Skokomish River in Mason county will get up around flood stage late Mon or Tue. We might see a few thunderstorms, mainly near the coast behind the front--naturally any squalls could help kick up the wind.

As the deep low weakens and crosses Vancouver Island Monday afternoon and evening southerly gradients will peak around the Seattle metro area. Looking at the Euro, PDX-BLI ought to be up around 10mb, so that is about half of the sort of gradient we see with our big windstorms, but it is still significant being early in the season. The GFS20 PDX-BLI gradient forecast only peaks around +7mb Monday evening, surely that is too low, and would give merely breezy weather.

Another rather typical looking front moves ashore on Tuesday- -the low pressure center with that front is off Haida Gwaii so that should be another blustery day but would fall short of needing much in the way of advisories. 19

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Periods of wet and blustery weather are likely but it does not look like we will see any deep low pressure centers like the one Sun/Mon. The frontal system for Thursday and Thursday night could send the rivers up and no doubt it will be called an atmospheric river--although it falls short of what we used to call a Pineapple Express and looks fairly progressive to me. Looking at the UW wrfgfs integrated water vapor transport suggests that the Oregon coast might be more under the plume from Wed through Thu evening. 19

AVIATION. West to southwesterly flow aloft this afternoon before becoming southwesterly this evening and into Sunday. FROPA has occurred for most terminals although some scattered showers are possible for the remainder of the afternoon. For most locations, drying conditions and very gradually improving sky conditions expected for this evening.

Still some spots of MVFR conditions, mainly either near showers or in the wake of the exiting front. Some terminals already popping back into VFR conditions and should see these conditions become more widespread this evening. Next round of precipitation will lower cigs again overnight, however recovery during the evening hours expected to be such that even this lowering will only be down to low-end VFR conditions. Main story with this next front will be associated surface winds, as they will ramp up by early Sunday morning and persist for the remainder of the TAF period. These surface winds will range from 10-20 kts sustained with gusts up to 30 kts possible.

KSEA . VFR cigs in place an expected gradually improve a bit this evening and overnight to around 5000 ft. Cigs lowering in advance of next system but only to around 3500 ft. Winds S/SE 5-10kts for the remainder of today and into tonight, ramping up to E/SE 10-15 kts around 12Z and persisting through the TAF period.

18

MARINE. Winds will gradually subside this afternoon and evening but this will only be temporary, ramping back up overnight back into headline criteria. In addition, swells of 11-13 feet will make for hazardous seas for the West Entrance of the Strait and the Coastal Waters/Grays Harbor Bar.

Still expecting a very strong low pressure system to rapidly deepen tonight and into Sunday over the open Pacific Waters, well outside the outer coastal zones. Nevertheless, strong winds are likely, with storm warning thresholds expected to be met for the Coastal Waters with sustained winds in the 40-50kts range. Easterly winds will pick up through the morning Sunday, with gales likely over most of the interior waters. A strong easterly push down the Strait is likely to result in Storm Warning level winds around the West Entrance.

By Sunday night, large swells are expected over the Coastal Waters, with seas building to between 25 and 30 feet. This will result in High Surf conditions. A High Surf Advisory is in place. Expect dangerous beach conditions along the Coast through much of Sunday and Monday.

This continues to look like a longer duration event as strong winds are expected to continue through Monday along with high seas. Gales are likely to persist over the interior waters for Monday, with storm warning winds over the coastal waters eventually subsiding to gale. Winds and seas will gradually subside through Tuesday but it is very possible hazardous marine conditions may continue into Tuesday morning. Yet another front around Thursday could bring another round of wind headlines along with large swells, though nothing to the extent of what is expected for Sunday/Monday.
