Area Forecast Discussion National Weather Service Seattle WA 215 AM PST Sun Jan 16 2022

SYNOPSIS. High pressure both at the sfc and aloft will make for foggy conditions in the lowlands through much of Sunday. A weak shortwave will bring light to rain to parts of the area on Monday, followed by another on Tuesday. A more organized system will then bring the best chance of widespread rain to the area Wednesday and Thursday before dry conditions set up again late in the week and through next weekend.

SHORT TERM /TODAY THROUGH TUESDAY/. The large scale pattern this morning is characterized by a weak Rex Block over the West Coast of the US as ridging prevails over the PNW and a closed area of low pressure resides off the CA Coast. No features of significance are noted upstream of the block, however, downstream a potent shortwave trough/closed low is noted over the SE US. Near the surface, high pressure remains the dominant influence over the PNW, with a weak frontal boundary noted upstream near Vancouver Island, while a weak inverted trough continues just offshore the CA Coast. Well downstream, a vigorous low remain associated with the closed SE trough over AL/GA.

Based on the above analysis, with upper level ridging and sfc high pressure, calm conditions have led to yet another fog-filled night across W WA. Expect these conditions to persist thru much of the morning since no notable changes in the atmospheric conditions are anticipated. Bufr soundings from the NAM and GFS indicate some low-level saturation up to about 975-950mb and this may be enough to squeeze out some drizzle. Fog will attempt to clear some by the afternoon but provided such little change in the pattern and the continuation of light wind, this may be a difficult achievement in some spots. Any areas that do see some clearing will likely experience mid level cloudiness, associated with the aforementioned frontal boundary near Vancouver Island.

More fog is expected Sunday evening and Sunday night despite the upper level ridge beginning to dampen. A weak shortwave trough will be approaching the area by early Monday morning. This feature should help drive some light precip towards and eventually thru the area during the day. QPF will be light and snow levels will remain above pass level through the afternoon. Another weak shortwave will follow the initial wave Monday night into Tuesday, perhaps bringing a better chance for light rain and mountain snow. Snow levels will drop below 4000 ft in the Cascades so may see around an inch of snow at Stevens Pass. As with Monday, QPF look light overall through Tuesday so do not expect sensible weather impacts through the short-term.

High temps will range in the mid to upper 40s across the lowlands, with lows in the upper 30s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. The long term forecast period will begin Wednesday morning with the overall pattern characterized by broad ridging over the West Coast and adjacent Pacific with troughing from the Rockies eastward. A warm front will be approaching W WA which should bring the next round of light rain to area. The cold front is expected to catch up quickly and make for the best chance of widespread light to moderate precip of the forecast period. Expect wet conditions Wednesday night through at least the first half of Thursday.

Ridging will amplify over the West Coast/NE Pacific Friday into weekend, with good agreement amongst the ensemble/ WPC clusters that W WA will be dry.

AVIATION. Widespread fog and low clouds might clear up for awhile in a few areas into the afternoon hours in light offshore flow. An upper ridge is over the region. There are also high clouds in westerly flow aloft. 19

KSEA . Low clouds and fog, maybe some afternoon sunbreaks.

MARINE. High pressure over the region will give way to a weak weather system on Monday and another one around Thursday. The system on Thursday might have a bit of a southerly breeze with it and an actual frontal passage but with the upper ridge trying to persist over the region we might see that front get weaker in the forecasts with time. 19

HYDROLOGY. No river flooding expected over the next 7 days.

SEW WATCHES/WARNINGS/ADVISORIES. WA . Dense Fog Advisory until noon PST today for Admiralty Inlet Area- Bellevue and Vicinity-Bremerton and Vicinity-East Puget Sound Lowlands-Eastern Strait of Juan de Fuca-Everett and Vicinity-Hood Canal Area-Seattle and Vicinity-Southwest Interior-Tacoma Area.

PZ . None.
