Area Forecast Discussion National Weather Service Seattle WA 740 PM PDT Sun Sep 27 2020

SYNOPSIS. Warm and dry conditions across Western Washington this week with strong high pressure aloft over the region. Temperatures warm more significantly starting Monday as offshore flow begins to develop, with temperatures expected to be well above normal through much of the week. A slight cooldown begins next weekend as the next disturbance may begin approach the region.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/. Clear skies in place over W WA this evening with temperatures ranging in the upper 50s to lower 60s at the time of this writing. Upper level ridging should keep clear skies in place . although some isolated spots more prone to fog such as Hoquiam and Olympia might see some development late tonight/early tomorrow morning For forecast details. please see the Previous Forecast Discussion section below. 18

From Previous Forecast Discussion . Warm and dry conditions will be the general rule across the region this week as strong high pressure amplifies over the region. Meanwhile, low level flow becomes northerly tonight before transitioning to more of an offshore (easterly) direction tonight into Monday. Expect to see some shallow fog or low stratus again in the typically fog-prone river valleys and near Puget Sound, but this is not expected to be particularly widespread otherwise given the increasing north to northeast flow overnight.

This sets the stage for plenty of sunshine Monday, with temperatures warming into the 70s across much of the area - a generally 5-7 degree increase over today's highs. A very similar day is expected Tuesday as compared to Monday, but few morning clouds given the continued drying of the air mass and temperatures will likely trend up another few degrees as the thermal trough over the coast intensifies a bit more. Wednesday generally looks like a copy of Tuesday across the interior, though the coast might see a little cooling later in the afternoon as the thermal trough begins to push inland allowing a late afternoon sea breeze to return.

Cullen

LONG TERM /THURSDAY THROUGH SUNDAY/. From Previous Forecast Discussion . The long term period looks to remain generally warm and dry, at least through most of the period. Guidance suggests the ridge will very gradually weaken through the late stages of the weak as the ridge axis slowly shifts eastward. Nonetheless, temperatures will still likely remain in the 70s inland, or several degrees above normal. Light offshore flow across the interior and some marine influence closer to the coast will likely continue. The next disturbance may begin to approach the area by the end of the weekend, returning temperatures closer to seasonal normals and perhaps a renewed chance of rain across the region.

One other note is that guidance suggests that some smoke from fires in northern California may be transported offshore and back around into the Pacific Northwest late by late Wednesday or Thursday. While confidence in the precise timing and just how concentrated the smoke may be remain quite low and depend on many factors (including fire behavior/smoke production and winds aloft), this wouldn't be expected to be nearly as widespread as the persistent smoke earlier this month. For now, just something to be aware of and continue to monitor in the coming days.

Cullen

AVIATION. High pressure will remain in control over the area through much of this week. Flow aloft will become westerly with surface flow remaining light, turning offshore tonight and Monday. VFR conditions into tonight. Fog is possible Monday morning along the coast and into the southwest interior for brief period of IFR to LIFR conditions. Otherwise VFR conditions will continue elsewhere through the period with a few high clouds.

KSEA . VFR conditions through the period. A few mid to high level clouds at times. Northerly winds 5 to 10 kts.

CEO/18

MARINE. Offshore flow will rule this week as high pressure builds into the area. For the most part, flow will remain light and below any headline criteria. Increasing long period swell Monday afternoon into Tuesday with 10 to 12 feet possible. Inherited small craft advisories for the coastal waters and for a rough bar in Grays Harbor Bar cover this cover this well and see no need for forecast updates with the evening package.

CEO/18

HYDROLOGY. Warm and dry conditions are expected through the next 7 days, with no significant rainfall expected across the region.
