Area Forecast Discussion National Weather Service Seattle WA 912 AM PST Sun Mar 7 2021

UPDATE. The cold front moved through this morning with scattered convective showers across the area. Isolated thunderstorms appear to be possible today with cold air aloft and some increasing instability by the afternoon. Small hail and gusty winds will be possible with any convective shower or thunderstorm. A brief rain/snow mix may be possible with any heavier shower, though chances are minimal and most likely be along the Foothills. Precipitation will taper off this later this evening.

SYNOPSIS. Scattered showers and possible isolated thunderstorms through today with an upper low offshore. Some showers may continue Monday, especially near the coast as the upper low remains offshore and slowly drifts south. Increasingly dry conditions Tuesday through the middle of the week, with rain chances returning late in the week as the next disturbance approaches.

SHORT TERM /TODAY THROUGH TUESDAY/. Latest satellite imagery reveals a well-organized low pressure system well northwest of the area, centered near 50N/138W early this morning. Meanwhile, the associated cold front is extending just offshore of the North American coastline from British Columbia south through Oregon this morning. Latest radar and surface observations show the band of heavier precipitation just ahead of the front is pushing onshore, and this front will continue to advance east across Washington this morning. The NOAA PSL profiler at Forks suggests the snow level is just below 2000 ft, so lowland rain and mountain snow is the expectation as this front pushes onshore. A little bit of wet snow may mix slightly lower in the heaviest precipitation, but any impacts should be minimal. Winds remain breezy this morning as the front advances, with gusts generally into the 30-40 mph range.

Behind the front, expect widespread showers this afternoon in the cooler, unstable air mass. The cooler air aloft will allow lapse rates to steepen and with relatively low freezing levels, expect that some of the stronger showers could contain small hail and a few isolated lightning strikes. The highest chance for lightning appears to be closer to the coast due to proximity to the coldest air aloft, and modeled thermal profiles are somewhat marginal for charge separation to occur, but nevertheless there remains some potential across much of the area for an isolated strike or two. Therefore, have retained the mention in the forecast for the Olympic Peninsula and generally Snohomish County southward. Temperatures Sunday night will likely be quite cool (especially south of Tacoma) with temperatures dropping near or below freezing. If the cloud shield remains more solid, temperatures could remain slightly warmer, but if the current forecast trends are correct there will be some potential for any residual moisture to freeze in these areas overnight into early Monday morning. However, the window looks to be short lived with temperatures rebounding quickly during the day on Monday.

As the main upper low lingers offshore into Monday, a few showers could develop across portions of the area from around Puget Sound to the west and south. The best chances will likely be closest to the coast, where the instability is expected to be marginal but better than more inland due to the proximity to the coldest air aloft. If any showers do develop, there is again a slight potential for an isolated lightning strike but the chance appears lower Monday than today.

Most of the area should be dry by Tuesday, though again a few lingering showers are possible near portions of the coast (mostly Grays Harbor County) as moisture may wrap around the upper low as it very slowly continues to drift south. Otherwise, a fairly average early March day is expected with decreasing clouds and temperatures near normal. Cullen

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Expect another chilly start to the day Wednesday with decreasing clouds overnight with high pressure aloft building into the region. Ensembles remain in good agreement in suggesting that Thursday remain mostly dry with the influence of the ridge still over the region, but confidence in the orientation of the ridge axis and how strongly the ridge builds over Washington remains somewhat lower; around 15% of ensemble members would maintain less of an influence, opening the door for the next disturbance to arrive and precipitation chances to increase by late Thursday night or early Friday (especially near the coast and Olympic Peninsula). In general, expect cool nights and near normal afternoon highs for most of the week. Cullen

AVIATION. Upper level troughing across the northeastern Pacific will maintain southwesterly flow aloft through the day. Radar this morning currently showing showers across the region in the wake of a cold front. The airmass is becoming increasingly unstable in the wake of the front, so a chance of thunderstorms remains possible for the coast and for areas along the Sound today. TAF sites across the region are generally VFR to MVFR for those in the vicinity of showers this morning. Expect this trend to continue as showers continue through the day and gradually taper across Western Washington tonight (near 06Z). Some locations may briefly see ceilings and visibilities drop down to IFR or even LIFR in the heaviest showers. Winds will be S sustained between 8-15kts thru the afternoon, with some gusts to 20-25kts, especially at KHQM, KPAE, and KBLI. Winds may also become gusty and erratic temporarily for terminals near or within any convective shower activity today.

KSEA . VFR conditions this morning, though conditions could drop down to MVFR or even IFR should any heavier shower activity make it into the vicinity of the terminal. Thunderstorms will be possible through the afternoon hours, but chances will gradually wane by tonight. Winds S 8-15kts, with an occasional gust towards 20kts possible through the afternoon. Winds may become gusty and erratic in the event that a thunderstorm develops in the near vicinity of the terminal.

Kristell/Borth

MARINE. Recent observations show that winds remain elevated across the majority of the area waters this morning in the wake of a frontal passage. Thus, small craft advisories are in effect for winds across the coastal waters and for the majority of the the inland waters through late this afternoon. Additionally, the airmass behind the frontal system is relatively unstable, so there is a chance for thunderstorms to impact the coastal waters as well as portions of Puget Sound today. Marine conditions in the immediate vicinity of any thunderstorms that develop may become erratic with brief gusty winds.

Seas across the coastal waters continue to hover between 10-12 feet at 9 seconds this morning. Another large swell train between 16-18 feet is slated to arrive in the region by late this afternoon, with seas gradually expected to subside throughout the day on Monday. Seas then relax by early in the week.
