Area Forecast Discussion National Weather Service Portland OR 416 PM PDT Mon Jun 14 2021

SYNOPSIS. Scattered showers will continue tonight in moist south/southwest flow before the last in a series of more significant shortwaves ejects eastward on Tuesday, bringing one last shot at organized rain. Rapidly building high pressure will bring a return to seasonable temperatures Wednesday, and then a rather rapid transition to prevailing summer-like conditions the remainder of the week. Temps should continue to gradually warm to above normal temps by this weekend and persisting into early next week - and perhaps beyond.

SHORT TERM. Tonight through Tuesday night . GOES-West water vapor and multispectral satellite imagery reveals the mean upper trough axis centered around 130W this afternoon, with continued moist, southerly flow on its eastern periphery across western Oregon/Washington. Forcing diagnostics, however, reveal only modest (at best) large scale ascent remains in place as we are in between systems this afternoon/evening. There will still be isolated/scattered showers around through much of tonight, initially driven by modest daytime instability this evening, and subtle low level lift overnight, but coverage is not expected to be widespread, and rainfall amounts should generally be light with the exception of the very few isolated locations that happen to be underneath heavier showers (such as what is currently ongoing near the Kelso/Longview area)

The vort max attendant to the last of a long series of more significant shortwaves rotating through the mean trof position is located near 43N/138W this afternoon, and this will make the turn eastward and come ashore on Tuesday/Tuesday night, deamplifying and shearing out as it does so. This will bring one last period of organized rain and probably at least a few weak thunderstorms. Precipitation doesn't look to be quite as widespread as the previous few waves, but sufficient instability and forcing for ascent should result in rather widespread showers and a few thunderstorms with coverage greatest along and north of roughly the Highway US 20 corridor, and especially southwest Washington. Precipitation will then end from southwest to northeast Tuesday night with rapidly building heights aloft and high pressure starting to build in the lower atmosphere. Miller

LONG TERM. Wednesday through Monday . Ridging is expected to build rather rapidly and strongly throughout the depth of the troposphere Wednesday-Thursday, with 24 hour 500 mb height rises between 150-200 meters across a large part of the Pacific NW. This will result in the end of precip chances, and a return to seasonal normal temps for Wednesday, and then a continued warming trend with a gradually drying boundary layer through the remainder of the 7 day forecast window. For Wednesday-Friday, wet ground and slightly higher boundary layer moisture content should hold temperatures in check somewhat, but most valley locations should reach into at least the mid 80s by this weekend, with 70s in all but the highest of elevations (and of course - cooler on the immediate coast with prevailing north winds). Many ensemble members from both the ECMWF and GFS suggest at least some potential for heat continuing to build during the early to middle part of next week and beyond, with quite a few members having high temps reach the low-mid 90s in the Willamette Valley. The most recent medium range ensemble forecasts for heat ended up not being quite as hot as initially advertised on days 5-6 and beyond, so we will see as this window comes more into focus over the next several days, but it certainly appears that a typically warm to hot, and sunny/dry pattern will commence beginning Wednesday-Thursday and persisting for the foreseeable future. Miller

AVIATION. Covering the 00z TAF issuance . South-southwesterly flow remains over the area in the post frontal environment, but will transition to a more westerly onshore flow after 03Z Tuesday. Marine stratus encompasses much of the area, but clearing continues moving from south to northeast. CIGs are lifting to VFR, but some MVFR persists north and east of KSLE. Clouds should continue to clear and lift to VFR over the next few hours. One exception may be KONP which has a tendency to get locked into IFR stratus. The flow pattern may make it difficult to break through, but most likely will see some improvements. Could see slightly enhanced southerly winds but not expected to exceed 15 kt. Overnight, a weak disturbance will pass over the area bringing another round of showers. With strongest showers, could see moderate rain, gusty winds and reduced visibility. Showers will persist through Tuesday. Slight chance for patchy fog formation after 10Z Tuesday in areas that experienced the most mixing and warming during the day today.

After 18Z Tuesday there is a slight chance for thunderstorms along the north coast, northern coast range, Willamette Valley, and along the Cascades. This is a slight chance situation so more likely thunderstorms will not be observed . but still worth mentioning. Thunderstorm chances should dissipate by 04Z Wednesday. Because locations are unknown and confidence is low, have left out of the TAF.

KPDX AND APPROACHES . Southwesterly flow through Tuesday morning as it becomes westerly. Showers are weakening and CIGs are lifting to low level VFR this afternoon. May still see short periods of MVFR CIGs but predominately VFR. Showers return overnight which may reduce visibility and create gusty winds at times. Slight chance for afternoon thunderstorms after 18Z Tuesday but confidence is low so have left out of the TAF. -Muessle

MARINE. An area of weak low pressure over the northeast Pacific will gradually dissipate over the next 24 hours and be replaced by high pressure. Along the leading edge of the low, south- southwesterly flow persists which is bringing slightly elevated winds to the waters - especially the central outer waters. Southerly winds 10 to 15 kt with gusts up to 20 kt likely. May see a few isolated gusts to 25 kt in the central waters but not expected to be widespread. These levels will persist through Tuesday morning as the transition to high pressure takes place. Expecting winds to become westerly Tuesday around 10 kt with gusts around 15 kt. Winds continue to shift becoming northerly by Wednesday morning. Gusty winds are likely, especially in the central waters where northerly winds 10 to 15 kt with gusts up to 20 kt. The northern waters will follow suit in the afternoon. Gusts up to 25 kt are possible in the early evening on Wednesday as the high pressure really begins to build. Winds will remain northerly through the remainder of the week, intensifying to around 15 to 20 kt with gusts up to 25 kt each afternoon.

Seas during this time will be fairly consistent at heights lower than 8 ft. Current seas are around 4 to 5 ft with a 9 second period. This will continue through Wednesday with a northwesterly fresh swell will take over. This fresh swell combined with a slightly amplified wind wave will bring seas to 6 to 8 ft at 9 seconds. Highest speeds will likely be in the central waters south of Newport. These heights will persist through the remainder of the week. -Muessle
