Fxus66 kpqr 191603 afdpqr area forecast discussion national service portland or 902 am pdt Mon aug 19 2019 Synopsis A warming trend through Tuesday will give way to a humid day with a chance of rain on Wednesday. The remainder of the week will be seasonable and dry, except for a small chance of precipitation on the southwest washington and far northwest oregon coast toward the weekend. Short term Today through Thursday... A few spots along and near the coast north of a tillamook-columbia gorge line have recorded measurable rain drizzle this morning, with the big winner being huckleberry raws at 0.07 inch as of their last report at 811 am. Most of the measurable rain has been in the hills, though astoria has had 0.04 inch as well. Increased pops in these areas to mention a chance of rain or drizzle this morning, and updated sky cover grids to reflect what is shown on visible satellite this morning. Otherwise, the existing forecast and discussion below look good and remain valid. weagle previous discussion follows... fog product satellite imagery early this morning reveals marine clouds are more patchy than the past couple of mornings. This should result in skies clearing faster today and high temperatures warming into the low to mid 80s in the willamette valley. Klgx doppler radar does indicate a few light showers are moving southeastward towards the north oregon and south washington coast so expect patches of drizzle through the morning hours in these areas. Building 500mb heights over the upcoming 36 hours should result in fewer marine clouds tonight into Tuesday morning with high temperatures warming several degrees on Tuesday. The biggest limiting factor for high temperatures on Tuesday will be increasing mid and high level clouds across the region in advance of the next storm system. The weather will change more dramatically as we move into Tuesday night and Wednesday as subtropical moisture phases with a shortwave trough dropping southward across the eastern gulf of alaska. A series of surface low pressures will develop and move north-northeastward across the northeast pacific along a boundary. Models are coming into agreement these will help to drive a moist surface front into southwest washington and northwest oregon on Wednesday. There still remains quite a bit of uncertainty on just much rain will fall across the region due to uncertainties in where weak surface low pressures do or do not develop along the front, though. Nonetheless, have continued the trend of raising pops in accordance with models coming into better agreement on the bigger picture. Naefs ivt values also continue to climb (now in excess of 500 kg ms) with each model run. These are values expected to occur once every 5-10 years in a three week window centered on the date and are at levels where orographics will certainly enhance rainfall in the coast range and willapa hills. Given some ensemble members of the GFS and ec suggest pw values could exceed or certainly come close to near record values for the region, do expect a rather humid and sticky feeling period on Wednesday in advance of the rain as well. Models are in good agreement the shortwave trough responsible for the unsettled weather on Wednesday will move east of the region Wednesday night into Thursday. This should result in the area drying out with decreasing cloud cover and temperatures topping several degrees below average for the date. Neuman Long term Thursday night through Monday... While models are in

reasonable agreement quasi-zonal flow will keep precipitation chances low and temperatures somewhat seasonable throughout the extended portion of the forecast, there are some differences between the gefs and eps ensemble means. The ec and its ensembles tend to support a gradual building of 500mb heights across the region as a broad, but shallow shortwave ridge builds over california this weekend. In contrast, the GFS and its ensembles keep lower 500mb heights in place across the region with a broad, but shallow shortwave trough over the northeast pacific and southwest canada. These subtle differences do lead to some uncertainty in high temperatures, at least for more interior locations. The cooler GFS scenario would likely keep high temperatures in the upper 70s and low 80s while the ec scenario would likely result in high temperatures climbing into at least the mid to upper 80s for the willamette valley and columbia river gorge over the weekend. In addition, the GFS scenario could lead to a weak front bringing some light rain to our far northern coastal zones Saturday. For now have gone with a blend of the model solutions given the uncertainty in all aspects of the forecast. Neuman Aviation Light west northwest flow expected to continue through the day with a slow transition to a more northerly wind pattern into the evening. Cloud cover is going to be the biggest challenge for today. Satellite is showing a fairly contained cloud deck within the willamette valley and coastal locations slowly breaking out. Overall the area will trend towardsVFR cigs. Currently, locations south of kuao have a MVFR deck that should start to improve over the next few hours withVFR conditions expected to slowly return between 19z and 21z Monday. Areas north of kuao while currently vfr should continue to improve in the same manner with the deck starting to break up by 19z to 21z Monday. Expect the marine stratus to reform tonight along the coast and within the willamette valley around 00z Tuesday. Kpdx and approaches...VFR conditions expected with a continuing trend towards the deck breaking out from now through 20z Monday. Around 00z Tuesday look for marine stratus to return with the possibility of MVFR cigs. 42 Marine Weak high pressure offshore for relatively quiet conditions over the waters. Seas remain in the 3 to 5 ft range, mainly from NW swell. North to northwest winds are expected to stay at 15 kt or less through Monday, so similar winds and seas as today. Significant changes begin Tuesday, with winds becoming s-se ahead of an approaching frontal system. Some forecast models suggest this front could be rather strong for august, potentially bringing small craft advisory-level southerly winds up to 25 kt tue night into wed. The wind wave and swell associated with this system may push seas up toward 10 feet Wed thu, with the best chance of 10 foot-plus seas being in our northern waters due to larger swells and potentially stronger wind.
