Area Forecast Discussion National Weather Service Seattle WA 900 AM PST Thu Mar 4 2021

SYNOPSIS. A slow moving frontal system just off the coast will move slowly inland through Friday. An upper level trough will move through the region Friday night and Saturday morning. Another weather system arrives Sunday. An upper level trough will remain just offshore during the first half of next week.

SHORT TERM /TODAY THROUGH SATURDAY/. Clouds will increase with rain developing on the coast--spreading inland late this afternoon. The front will stall near the coast tonight and the upper level trough will dig further south off the West Coast. A second frontal wave will arrive Friday and the cold front will finally shift through the interior of Western Washington. There's a Winter weather advisory for the Olympics with snow at the higher elevations and with a decent amount of rain in the lower elevations in southerly flow aloft a flood watch for the Skokomish River in Mason county. After the front moves through, the air will destabilize for a chance of a couple of thunderstorms near the coast, and the upper trough will shift ashore on Saturday keeping showers in the forecast. 19

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Extended models and ensemble solutions in good agreement with another front moving through Western Washington Sunday. Snow levels in the Cascades will be down around 2000 feet for snow in all the passes. Good agreement in the extended models continues into the first part of next week with a large vertically stacked low moving south off the west coast Monday through Wednesday. Ensemble solutions have a few members, less than 20 percent, with light precipitation. Model blend gives slight chance pops through the period. With some good consistency in the models at this point going to go dry for the most part Monday through Wednesday and keep the slight chance of showers wording just over the southern portion of the area at times. Highs will continue to be a little below normal, a couple of degrees either side of 50. Felton

AVIATION. Southwesterly flow aloft with an upper level ridge to the east of the area and a frontal system offshore this morning. Breezy conditions expected this afternoon, mainly for terminals along the coast (KHQM) and across the Northern Interior (KPAE,KBLI). Increasing clouds today as the frontal system approaches the coast, with rain likely beginning across Puget Sound between 23-03Z.

KSEA . Southerly winds continuing through the day, generally between 5-10 knots. Increase in cloud coverage expected as the frontal system nears the area. Latest hi-res guidance shows rain likely beginning at the terminal between approximately 23-02z.

Kristell/Borth

MARINE. A vigorous cold front will arrive later today and slowly move through the waters into Friday. Winds across the coastal waters and northern interior waters have already started to increase this morning.

Meanwhile, offshore swells will continue to build this morning and remain elevated, between 13-16 feet, into Friday morning before decreasing Saturday. Another swell train will then arrive in the region on Sunday.

A number of marine headlines are posted for area waters today and into Friday evening, including offshore gale warnings, and Small Craft Advisories for much of the inland waters. Additional marine headlines may be posted Sunday into early next week as the unsettled pattern continues.

Kristell/Borth

HYDROLOGY. Stalling front will keep rain focused in the Olympics in southerly flow aloft (with snow higher elevations). With 2-3" of rain for the Skokomish basin, a flood watch is up for that river. 19
