Area Forecast Discussion National Weather Service Seattle WA 951 AM PDT Wed Sep 23 2020

SYNOPSIS. A series of vigorous frontal systems will bring wet and windy weather at times the next several days. High pressure aloft will build over the area the first part of next week for a return to dry and warmer weather.

SHORT TERM /TODAY THROUGH FRIDAY/. The anticipated atmospheric river has arrived across the region as heavy rain continues across the Olympic Peninsula and much of the region. Latest satellite derived precipitable water in excess of 1.5 inches extends across the Pacific and into the region, well supported by the 1.42 from this morning's upper air sounding at UIL. 1-2 inches of rain already measured in the Olympics in the higher terrain. The axis of moisture and heavier rain will continue to slowly shift to the south as the day goes on. Some stronger winds through the northern inland waters and over the coastal areas, but still expect to see the winds and heavier rain to increase this afternoon and into evening across the Puget Sound region. Behind the main rain line, will still be monitoring the potential for thunderstorms this evening and tonight. Lightning is currently detected well offshore extending south from the northern portion of Vancouver Island, giving some perspective on the potential environment that may develop this evening across the western portions of the forecast area (generally over the Olympic Peninsula and into the southwestern Washington), and across much of the region on Thursday. Will continue to evaluate this threat.

Another frontal system in the westerly flow aloft approaches late Thursday and into Friday. This will bring widespread rain to the region, as well as locally windy conditions across the area early Friday.

Cullen

LONG TERM /SATURDAY THROUGH TUESDAY/. Previous discussion. Additional frontal waves in the westerly flow aloft will keep conditions wet and windy at times Saturday and Sunday. An upper ridge will rapidly build over the area Monday and Tuesday which will dry things out. A thermal trough will develop just off the coast for offshore flow by Tuesday which will allow highs to warm back into the 70s. Schneider

AVIATION. An early Fall storm system will bring widespread rain to the terminals through the TAF period. As the rain continues to spread east through the morning, expect all terminals to be affected, with ceilings dropping to at least MVFR (perhaps IFR at times), through the day today with little recovery. IFR visibility will also be possible within areas of heavier rain. Rain will eventually taper to showers overnight tonight into Thursday. Winds will noticeably pick up today out of the south, sustained generally between 10 to 20 mph with gusts 20 to 30 mph (could be locally higher at a few sites). Winds will ease late Wednesday night into Thursday.

KSEA. VFR through the early morning hours, dropping to MVFR as rain moves into the area this morning. Rain showers will continue to fill in through the day. Winds south sustained 10-20 mph with gusts around 25 mph beginning late this morning.

Kovacik/Kristell

MARINE. A series of robust frontal systems will affect the waters over the next several days. Latest sfc analysis this morning reveals a frontal system over the offshore waters of the WA Coast. A widespread area of rain was noted out ahead of the warm front, pushing inland across the Olympic Peninsula this morning. Rain will continue east through most of the day, with winds also picking up as front progresses inland. Current headlines remain in place with Gale Force winds expected over the Coastal Waters/Western Strait of Juan de Fuca and the Northern Inland Waters/Eastern Strait of Juan de Fuca, and Admiralty Inlet. Elsewhere, Small craft Advisory level winds are expected. Winds will gradually ease through the overnight hours into Thursday as the front passes, however, shower activity will persist.

Waves will increase over the Coastal Waters with the frontal system today, generally to between 10-12 feet. A more significant swell is likely on Thursday with waves building to between 14-16 feet. If this trend continues, a High Surf Advisory may be needed. Waves may continue into Friday before finally subsiding.

Additional frontal systems will affect the waters through the remainder of the week and through much of the weekend. Periods of elevated winds and agitated seas can be expected.

Kovacik/Kristell

HYDROLOGY. The anticipated atmospheric river has arrived, with 1-2 inches of rain in the Olympics and northern coastal areas today. Expect another few inches today in the high terrain and closer to 1 inch in the lower elevations as this moisture plume continues, with the focus shifting south into the evening. Sharp rises are anticipated on several rivers and streams flowing from the southern Olympics (including the Skokomish) and portions of the Cascades. While rivers should recede a bit Thursday as steady rain transitions to showers, additional heavy rainfall Friday and Saturday could bring additional rises to rivers - particularly those draining from the northern Olympics and North Cascades, though possibly elsewhere, too.
