Area Forecast Discussion National Weather Service Seattle WA 220 AM PDT Sun Sep 19 2021

SYNOPSIS. Active weather to persist today with additional rainfall from scattered showers and thunderstorms, and upper elevation mountain snow. Drier and warmer conditions expected on Monday and Tuesday before another system brings showers and cooler temperatures to the region midweek. Drier and warming weather for the end of the week.

SHORT TERM /TODAY THROUGH TUESDAY/. Scattered showers continue to persist across the region early this morning with a few isolated lightning strikes observed along the outer coast at times. Upper trough will remain in place over Western Washington today as the trough axis swings across the region this morning and begins to lift out of the region later today. A similar environment will be in place today, with cool mid-level temperatures approaching -25C at 500 mb. Similar scenario today with sun breaks at times through the morning will see some modest instability develop by early afternoon. CAPE values likely wont be quite as high as what was observed on Saturday, but pockets of 250 to 500 J/KG of CAPE is not out of the question. Scattered showers will increase in coverage around 18Z and persist through the afternoon, with the strongest updrafts capable of yielding thunder. The latest HREF guidance continues to indicate the development of a convergence zone in the area of King and Snohomish Counties around 00Z (4pm LT) as upper level flow becomes westerly. Heavy rain, small hail, and lightning will all be threats with the strongest storms, and especially within the convergence zone this afternoon. If you have travel plans in the metro area or along the I-90 corridor, be sure to slow down and use low beam headlights in torrential rain. Showers and storms will taper off across the lowland areas late tonight, becoming confined to the Cascades through mid-Monday morning before dissipating.

Shortwave ridging will begin to build into the Northwest Monday bringing a return of drier and slightly warmer weather. The ridge axis will cross the region on Tuesday, likely making it the warmest day of the week. High temperatures will likely reach the low 70s in parts of Western Washington.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Dry and quiet weather will be short-lived across the region as another system is slated to move across the region late Tuesday night through Wednesday. This system looks much weaker than the front that pushed across the region this weekend. Nonetheless, another round of rain and breezy conditions can be expected. Unsettled conditions will likely only last through Tuesday night, as ensemble guidance has a strong signal in shortwave ridging building back in to end the week. Following a brief dip in temperatures on Wednesday with the passage of the weak front, temperatures will gradually warm, topping out in the low 70s by Friday once again.

Pullin

AVIATION. Upper trough moving inland over the Pacific Northwest today with westerly flow aloft. The air is moist and unstable with scattered showers and we might see a couple of thunderstorms again today. A few areas of morning low clouds will develop and the mountains will still be obscured at times in showers. A PSCZ is likely for a few hours late in the afternoon north of Seattle.

KSEA . Scattered showers with cigs dropping occasionally and there might be a few hours of morning stratus around daybreak. A convergence zone will probably make the winds variable late this afternoon.

19

MARINE. The trough over the area will move inland today. There will be an evening westerly in the Strait of Juan de Fuca worth an advisory. A small craft advisory for the coastal waters is up for seas around 11 feet and the Grays Harbor Bar also has an advisory. High pressure will transit the area Monday and Tuesday and a weak front will break up over the coastal waters Tuesday night or Wednesday.
