Area Forecast Discussion National Weather Service Seattle WA 842 PM PDT Sat Aug 8 2020

UPDATE. Skies continue to clear this evening as an upper level ridge starts to build back into the region. Will likely see some clouds develop along the coast again overnight, however expect a sunnier and warmer day across the region on Sunday. No major updates were needed to the forecast package this evening. The previous discussion follows, with updates made to the marine and aviation sections. 14

SYNOPSIS. Clearing skies and dry conditions this afternoon. Clear skies and warming temperatures will persist into Monday. Another weak system will bring cool temperatures Tuesday and Wednesday followed by some possible showers for the latter part of the week.

SHORT TERM /TODAY THROUGH TUESDAY/. Both satellite and a peek out the window shows clouds very gradually breaking up east of the Sound this afternoon while clear to scattered conditions are present over the W half of the CWA. Current obs show how the differences in cloud cover have impacted area temps . with coastal obs sites reporting in the mid 60s while some sites east of the Sound are actually lagging behind that. Not so much though as to throw off inherited high temps as temp trends combined with a couple more hours of heating should do the trick.

Models remain on track for generally dry conditions this afternoon and throughout the weekend . even stretching into Monday . as an upper level ridge sets up over the area. This will result in generally clear skies for the area which will help afternoon highs Sunday and Monday climb back to near seasonal normals. Interior highs Sunday will rebound into the mid to upper 70s and Monday will see conditions get to maybe just a degree or two above seasonal normals with highs in the upper 70s to lower 80s.

An upper level low well to the north in Canada will drag an associated trough through W WA Tuesday. Current deterministic models keep any associated precip north of the border and ensemble members agree . so will dry out this portion of the forecast for the afternoon package. Cool temps with this feature remain in the forecast though . with mild temps expected in the interior as highs will range from the lower to mid 70s. 18

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Wednesday still on track to be the coolest day of the week although . as stated above . generally dry conditions expected to be in place. Some locations in the northern third of the CWA could possibly see some precip . but current PoPs below 15 pct. Thursday sees another upper level trough pass through the area . but this time the feature may plunge south enough to bring some chance of showers to the area. Deterministic models differ on this though . with the GFS keeping the feature far enough to the north for nothing to happen while the ECMWF manages to bring in an impressive slug of moisture. Given the time of year as well as the minimal confidence inspired by this divergence in solutions . to say nothing of the ensembles general meh on the matter . have opted to split the difference with only slight chance to low end chance PoPs in the forecast at this time. An upper level ridge starts to build over the area late in the afternoon Friday and intensifies Saturday . returning dry conditions to the area during this timeframe. Temps throughout the long term will gradually warm but never really getting above seasonal normals. 18

AVIATION. There were clouds this evening in much of the Puget Sound area south of about Poulsbo and also over the Cascades. Elsewhere skies were mostly clear. There will be some areas of morning low clouds, otherwise sunshine will be the rule on Sunday as an upper ridge shifts toward the area.

KSEA . Clearing skies and a northerly breeze this evening. Sunday will be sunny as an upper ridge shifts toward the area.

MARINE. Westerly small craft advisory level winds are likely in the Strait of Juan de Fuca most evenings. At least a couple of weak weather systems will reach the area in the week ahead-- strengthening onshore flow at times. Over the coastal waters, seas are forecast to get up around 10 feet Monday night and 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 . None. PZ . Small Craft Advisory until 2 AM PDT Sunday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.

Small Craft Advisory until 8 AM PDT Sunday for Coastal Waters From Cape Flattery To James Island 10 To 60 Nm-Coastal Waters From James Island To Point Grenville 10 To 60 Nm- Coastal Waters From Point Grenville To Cape Shoalwater 10 To 60 Nm.
