Area Forecast Discussion National Weather Service Portland OR 232 PM PDT Thu Aug 6 2020

SYNOPSIS. Lingering showers will dissipate this evening as high pressure returns to the Pacific Northwest. Friday will be drier with plenty of afternoon sunshine and mild temperatures. The tail end of a weak cold front will likely brush our northern zones Saturday morning, deepening the marine layer and perhaps bringing some patchy drizzle to coastal areas. Drier weather returns later Saturday through Monday, along with a warming trend to above normal temperatures by early next week.

SHORT TERM. Tonight through Sunday . Visible satellite imagery shows that sunbreaks are increasing from west to east across the forecast area this afternoon, behind a cold front which is moving eastward across the Cascades. Rainfall totals from this front overperformed expectations a bit, with 0.19" at PDX Airport and 0.27" at Troutdale. Mostly light rain continues in the Cascades, but should taper to scattered showers as drier air moves in aloft. Showers will become increasingly confined to the higher terrain toward sunset, with showers likely coming to an end across the forecast area by midnight tonight.

Friday will start out cool but dry, with areas of morning clouds as high pressure builds back into the Pacific Northwest. Any morning clouds should give way to sunshine by midday as clouds clear off the coast. Given the cool and potentially cloudy start and continued onshore flow, temperatures Friday will probably remain a little below average with inland highs ranging from the mid 70s to lower 80s. 12z HREF and deterministic GFS suggest high clouds ahead of our next weak frontal system will begin spreading into NW portions of our CWA by Friday evening, with clouds increasing and thickening overnight as the front approaches. Models have been trending slightly stronger - or perhaps better said, less weak - with this front over the past few runs, with several deterministic models and ensembles suggesting some light precipitation for our north coastal zones. At this point, moisture seems too shallow for significant precip east of the Coast Range Saturday morning.

Given the models' deeper trend with the marine layer Sat morning, morning clouds could be fairly extensive and persistent. However the clouds should clear back to the coast by early or mid afternoon, allowing temperatures to climb back into upper 70s to mid 80s inland. Sunday will be considerably warmer as low amplitude upper ridging tries to push into the Pac NW. Meanwhile, a thermal trough of low pressure will be strengthening along the south Oregon coast, causing low-level flow to veer more northerly. With low-level flow turning less onshore and a shallower marine layer due to 500 mb heights in the upper 580s, it seems reasonable to think temperatures could make a run at 90 degrees inland Sunday and/or Monday. Weagle

LONG TERM. Monday through Thursday . As mentioned above, low amplitude upper ridging appears likely to build over Oregon and possibly Washington by Monday, leading to above normal temperatures inland. After Monday longer range models' solutions begin to differ, but the majority solution appears to favor some sort of upper trough development over the Pac NW by midweek. Again, models vary considerably on the strength of this upper trough and whether or not it will be strong enough to bring us rain, so we held close to the NBM solution which generally keeps our CWA dry. After a warm day Monday, temperatures should cool back closer to seasonal norms or perhaps slightly below that by midweek. Weagle

AVIATION. Onshore flow behind the front continues to bring isolated showers this afternoon. But these showers will diminish in the evening as the air mass stabilizes with the sun setting. VFR conditions prevailing but expect some local MVFR with showers. Also mountain obscuration with scattered showers can be expected into the evening hours. But the overall trend is for showers to end and clouds dissipate some. Should see enough clearing and stabilization of the air mass tonight for some fog or low stratus development early Fri, but confidence in widespread coverage is low at this time.

KPDX and APPROACHES . Conditions continue to improve this afternoon as high pressure build in behind the front that move through this morning. VFR will continue into tonight with spotty showers for the early evening hours. May have a stray MVFR cigs but expect it to be brief enough not to include in forecast. Will have to watch for MVFR cigs or vis developing early Fri morning.

MARINE. Northwest wind over the waters this afternoon as high pressure builds behind the front. But winds back to more westerly in the northern zones as a weak front approaches the waters Fri morning, then southwesterly as it moves into the waters Fri evening. High pressure rebounds rapidly Sat an may bring northerly winds gusting 25-30 kt Sat afternoon and continuing at times into Monday. Seas near 5 ft today and Fri, but 7-9 ft are expected over the weekend with periods of steep and choppy conditions likely. Northerly winds continue through much of next week with seas around 5-7 ft.
