Area Forecast Discussion National Weather Service Seattle WA 824 PM PDT Tue Jul 7 2020

UPDATE. Clouds and some sunshine this evening across Western Washington as the system slides east of the area. A few showers currently across the South Sound with weak convergence activity across southern King and northern Pierce Counties. Light rain possible in this area into tonight with drier weather on Wednesday as weak ridging builds into the area.

SYNOPSIS. A few showers around into tonight as an upper disturbance departs the area. After a short break on Wednesday for drier weather, additional disturbances will rotate across the region Thursday and again over the weekend, maintaining cooler than normal conditions and a few rounds of precipitation through early next week.

SHORT TERM /TONIGHT THROUGH FRIDAY/. Latest satellite imagery depicts an upper trough axis aligned across the state this afternoon, with a persistent cloud deck and scattered showers. Per latest NWS radar imagery, most showers are organized either across the southern/western parts of the forecast area or in a region of developing convergence across the northern and central Puget Sound. Expect to see the atmosphere begin to dry out in the mid- levels later tonight and into Wednesday as a weak upper ridge of high pressure pushes into the region. This should bring showers largely to an end for most locations, though weak onshore flow will continue tonight and a lingering Puget Sound Convergence Zone may develop and persist through much of the night. Elsewhere, the weak onshore flow should serve to maintain a relatively solid lower cloud deck. For some areas that do begin to scatter out, there may be brief a window for localized fog to develop in the more favored locations toward daybreak, but many locations should instead maintain a more solid cloud deck. With the drying trend and weak onshore gradients into Wednesday, expect morning clouds to eventually give way to increasingly sunny skies by the afternoon. The slightly warmer air mass and decreasing sky cover should allow temperatures to rebound into the lower 70s for the interior lowlands.

However, the break in the weather looks be short-lived as the next upper trough quickly approaches Western Washington late Wednesday. Expect to see an increase in mid-level clouds streaming into the region by Wednesday evening, with some guidance indicating the leading edge of rain reaching the coast during the late afternoon or early evening hours, before advancing inland overnight and into early Thursday. This will likely yield another cool and damp day across the region on Thursday, with rain eventually tapering off from southwest to northeast later in the day. Much of the interior lowlands may be a bit shadowed in the predominantly southwesterly flow, but precipitation amounts up to around half an inch are possible in the more favored terrain of the Olympics and Cascades. Behind this system, another round of higher pressure and warmer temperatures looks likely for Friday with plenty of sun after morning clouds. Of course, the rather progressive weather pattern continues with yet another disturbance quickly following.

Cullen

LONG TERM /SATURDAY THROUGH TUESDAY/. The next weather system will then approach the region over the weekend. Current guidance suggests that this low pressure system may be a bit stronger and better organized that recent systems, with a slightly slower trend in recent model runs. However, there is a significant bit of spread in guidance, likely partially due to the potential influence of a strengthening ridge across the southwestern U.S. Nonetheless, the front is expected to push across Western Washington over the weekend with another round of increasing clouds and precipitation chances. Onshore flow then follows into early next week, with at least some chance of showers (especially across the higher terrain and near the coast), but flow aloft likely becomes more zonal with temperatures returning to near or slightly below normal values closer to midweek.

Cullen

AVIATION. Northwesterly flow aloft will transition westerly on Wednesday with weak ridging over the area. VFR cigs for most this evening with MVFR along the coast and across portions of the central and southern Puget Sound with weak convergence activity. MVFR late tonight through Wednesday morning with onshore flow and stratus. VFR cigs expected Wednesday afternoon with more clearing through the day. Winds south across the South Sound and light northerly across the central Sound into tonight. South winds across the area for Wednesday 4 to 8 knots.

KSEA . VFR cigs this evening with MVFR at times with convergence activity around the central Puget Sound. Drier weather late tonight through Wednesday. MVFR cigs late tonight through Wednesday morning with VFR in the afternoon. Light north winds tonight will transition south 4 to 8 knots Wednesday morning. JD

MARINE. Onshore flow through the week with mainly light winds as a few systems move through the area. Small Craft Advisory winds this evening into early tonight for the central and eastern portions of the Strait of Juan de Fuca. SCA winds possible at times through the Strait of Juan de Fuca this week with the onshore flow. JD

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 1 AM PDT Wednesday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.
