Area Forecast Discussion National Weather Service Seattle WA 720 PM PDT Thu Aug 13 2020

SYNOPSIS. A warm upper ridge will nose into the area with much warmer weather on tap for the weekend. Temperatures will peak across the inland portion of Western Washington Sunday before easing Monday and Tuesday as the ridge weakens.

SHORT TERM /TONIGHT THROUGH SUNDAY/. Clear skies through Friday and high temps on Friday will warm to around 80 in the typically warmer spots. High pressure aloft will build fully over the region Saturday with low level flow becoming offshore during the day - allowing temperatures to warm further. Areas in the interior particularly east of I-5 will reach into the mid to upper 80s and from Tacoma-Olympia southward into the low 90s. Ensemble guidance continuing to advertise warmest temperatures Sunday, trending a bit warmer than previous forecasts with most locations through the interior reaching to the mid 80s to mid 90s. The warmest temperatures continue to be expected east of I-5 and south of Puget sound where temperatures could rise into the upper 90s, especially in the Cascade valleys. Temperatures this warm and widespread represent heat risk concerns with most areas seeing a potential for at least moderate heat risk. The warm temperatures coupled with the dry conditions also highlight fire weather concerns, especially in the Cascades.

LONG TERM /MONDAY THROUGH THURSDAY/. The forecast for Monday continues to reflect a transition day as the upper level ridge shifts eastward and low level onshore flow develops. This will bring relief to the coast with high temperatures dropping back into the 60s. As is often the case, interior will remain warm one more day with high temperatures reaching into the mid to upper 80s for the warmest locations. Overnight lows will cool Monday night back down into the 50s. The forecast continues to reflect a low chance for some spotty, high-based showers over the Cascades. Onshore flow will help bring a bit more cooling to the interior Tuesday with highs reaching in the lower to mid 80s. A more fully developed, and stronger onshore push Wednesday will bring conditions back to normal with increasing clouds, cooler temperatures and even a few passing showers as a trough moves into the area Wednesday into Thursday.

AVIATION. Clear skies. There might a few patches of low marine clouds along the coast around daybreak.

KSEA . Clear skies, north breeze.

MARINE. A small craft advisory is in effect for the typical wly push down the Strait of Juan de Fuca this evening. The afternoon northerly looks a bit breezy along the coast Friday afternoon and there is a small craft advisory up for that. Over the weekend the air mass will heat up under thermally induced low pressure and gradients should be fairly light until marine air pushes back into the area by Sunday evening.

FIRE WEATHER. Significantly warmer temperatures continue to be expected this weekend with maximum values reaching well into the upper 80s and 90s by Sunday. Dry and unstable conditions are also anticipated across the Cascades and lowland areas south of Olympia - which could lead to critical fire weather conditions particularly on Sunday. Minimum relative humidity values in those areas will drop into the 20s with mid-level Haines values of 6. There remains uncertainty regarding the weather pattern beyond Sunday particularly the transition to cooler conditions Monday into Tuesday.

HYDROLOGY. The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed until then.

SEW WATCHES/WARNINGS/ADVISORIES. WA . Excessive Heat Watch from Sunday morning through Sunday evening for Bellevue and Vicinity-Bremerton and Vicinity-Cascades of Pierce and Lewis Counties-Cascades of Snohomish and King Counties-Cascades of Whatcom and Skagit Counties-East Puget Sound Lowlands-Everett and Vicinity-Hood Canal Area-Lower Chehalis Valley Area-Seattle and Vicinity-Southwest Interior-Tacoma Area.

PZ . Small Craft Advisory from 1 PM to 11 PM PDT Friday for Coastal Waters From James Island To Point Grenville Out 10 Nm- Coastal Waters From Point Grenville To Cape Shoalwater Out 10 Nm.

Small Craft Advisory until 5 AM PDT Friday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
