Area Forecast Discussion National Weather Service Seattle WA 300 AM PDT Fri Jul 10 2020

SYNOPSIS. Dry weather and slightly warmer temperatures return for Friday into much of Saturday before another weak system brings a chance for showers on Sunday. The start of next work week is looking dry.

SHORT TERM /TODAY THROUGH SUNDAY/. Current radar not showing much this early morning but looking at satellite suggests there may yet still be a stray shower out there this morning over eastern portions of Snohomish and King counties. Not a lot to these individual cells and would not expect much from them . likely not surviving past sunrise.

W WA looks to be in store for a dry day today as upper level ridging traverses the area and even as the ridge axis moves east of the area this afternoon. An upper level low off the coast will try to push inland Saturday but neither the deterministic models nor the ensembles are particularly excited about the prospect of precip with this system as it appears to fall apart as it crosses the area. This system will linger into Sunday . again with PoPs having a hard time getting out of chance category . save for locations in higher elevations. A Pacific upper level ridge will then start to nudge into the area for dry conditions to resume Sunday evening.

Not much fluctuation in temps today and Saturday with highs in the interior lowlands generally in the lower to mid 70s while coastal locations can look forward to more mild conditions with highs generally in the mid 60s. Sunday will see conditions cool slightly thanks to the passing system with the interior lowlands generally around 70 and the coast in the lower 60s.

LONG TERM /MONDAY THROUGH THURSDAY/. Upper level ridging will bring a return to dry conditions Monday and most of Tuesday. Deterministic models are trying to show some sort of weak disturbance or front that wants to try and dip down into W WA Tuesday evening . but neither model really pulls it off. Ensemble members . however . are all over the board which is impacting PoPs in the forecast. While the general consensus remains unimpressed and would wager that the Tuesday night thru Wednesday morning time frame will likely remain dry . the ensemble mean does rise somewhat and as such . PoPs are present in the forecast. The ECMWF shows a better organized lobe off an upper level low over central Canada that should result in some precip over the area . however the GFS keeps things to the north and the ensembles maintain their general ennui/apathy toward any significant precip . once again keeping PoPs generally slight chance to low-end chance. Deterministic models in agreement that a weak upper level ridge should bring dry conditions Thursday while ensembles remain in their emo phase with low end PoPs in the forecast closing out the long term in a similarly adolescent mindset of low confidence. 18

AVIATION. Westerly flow aloft will become southwesterly late tonight as another upper trough moves into the offshore waters. Stratocumulus and some stratus has filled in across much of the lowlands with areas of high end MVFR ceilings. Expecting this to scatter out to VFR by mid to late morning with weak upper ridging building into the region. Low MVFR in stratus returns to the coast tonight, but expecting much of interior to remain VFR overnight.

KSEA . High end MVFR possible at times through about 18Z or 19Z then VFR through tonight. Surface winds light becoming W-SW this morning . then shifting to northerly by late this afternoon. 27

MARINE. Surface high pressure will remain over the coastal waters with lower pressure east of the Cascades over the next several days. Weak weather systems passing through the region will increase the onshore flow from time to time. Westerlies in the central and eastern portions of the Strait of Juan de Fuca will reach small craft advisory criteria most afternoons/evenings over the next few days, otherwise winds and seas will remain rather quiet. 27

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 from 5 PM this afternoon to 3 AM PDT Saturday for Central U.S. Waters Strait Of Juan De Fuca- East Entrance U.S. Waters Strait Of Juan De Fuca.
