Area forecast discussion National Weather Service Portland or 245 PM PDT Tuesday Sep 16 2014 Synopsis...a low pressure system currently well off the Oregon coast will move towards southern Oregon and bring a chance of showers late Wednesday into Thursday across northwest Oregon and southwest Washington. Onshore flow will keep most of the smoke from the 36 pit and deception complex fires over the Cascades and points east. However...high pressure and offshore flow looks increasingly likely to build over the region towards the weekend so expect smokey conditions and temperatures possibly approaching 90f again across the Willamette Valley. && Short term...tonight...water vapor satellite imagery shows a large shortwave trough located off the California coast...placing the County Warning Area under deep south to southwesterly flow aloft. Visible satellite imagery shows the first round of middle to upper level clouds pushing northward off the Oregon coast and across southwest Washington. Doppler radar indicates some light precipitation is falling out of these clouds...but suspect this is almost entirely virga. Another cluster of virga currently off Cape Mendocino should track along the Oregon coast this evening. The 36 pit and deception complex fires continue to produce plenty of smoke. Continue to check with your state air quality agency for the latest air quality observations. Expect valley locations immediately down river of these fires like Estacada and Oakridge to experience problems with smoke each night and early morning this week. Fortunately...west winds each afternoon and evening should disperse smoke...especially when the fires are generally most active....to the east. For Wednesday...models agree the upper level trough and surface low pressure currently well off the California coast will shift northeastward towards the California/Oregon state line through Wednesday evening...before splitting and nose diving into Southern California late Thursday. This rather messy pattern will result in waves of mainly middle to upper level clouds spreading across the area through Wednesday evening. Aside from a few sprinkles from time to time...suspect most locations will remain dry based on model soundings. Kept a slight chance mention of thunder across our southeastern zones Wednesday afternoon and evening where perhaps enough middle level instability could generate a lightning strike or two...but confidence in this scenario panning out is very low. For Thursday...the NAM and GFS suggest a low level surge of isentropic lift ahead of the trough axis late Wednesday night into Thursday morning may saturate the atmospheric column and result in light precipitation across much of the area Thursday morning. Low level westerly flow should also aid in wringing out light rain across the orographically favorable Coast Range and Cascades. As a result...probability of precipitation were nudged upwards during this period into the low end likely category along the coast and across the topography...and high end chance category for valley locations. Models suggest cloud cover will be ample on Thursday...but if we do get any breaks in the clouds...it will not take much heating to produce thunderstorms. At this point...cloud cover looks pretty solid Thursday so left the mention of thunder out of the forecast...but this will be Worth monitoring over the next 48 hours. Overall...continue to remain nervous that models are too aggressive with the moisture and precipitation chances late Wednesday into Thursday given the splitting nature of the upper level trough. In addition...this will be the first fall like storm system to try and break down the longwave ridge...which also does not Bode well. For Friday...shortwave ridging moving into the area late Thursday into Friday should allow the area to dry out considerably. Strengthening thermal low pressure over California on Friday will turn winds more northerly...and the area will begin another warming trend. /Neuman Long term...Saturday through Tuesday...GFS...dgex...and European model (ecmwf) all show a return to easterly flow on Saturday which will warm temperatures across the area. This warm up will only last through Sunday...as winds shift back to the west from an upper-level trough and associated cyclone deepening over the Gulf of Alaska. This will cool temperatures and bring the marine layer back in at night Monday and Tuesday. -McCoy && Aviation...light southeast winds have helped clear the marine clouds sooner than anticipated this afternoon. Marine stratus with MVFR ceilings should fill in along the immediate coast after 0z. Onshore winds across central Oregon coast will bring some clouds through the coastal gaps near konp early this evening...and up the lower Columbia River towards kspb.. light south to southeast winds will develop late tonight and prevent the clouds to move much inland. Would not be surprised if the marine clouds actually push away from the coast early Wednesday morning. There may be a brief period of low MVFR for the southern Willamette Valley including keug around 09z...but forecast confidence is low for keug ceilings. Smoke from the 36 pit wildfire will generate MVFR ceilings in vicinity of the fire. This smoke should remain mostly over the Cascade foothills this afternoon and evening...but may expand its coverage when the winds calm late tonight...and possibly impact parts of the northern and central Willamette Valley early Wednesday morning. Kpdx and approaches...VFR today and tonight with a mix of high clouds. Tj && Marine...fairly benign conditions persist over the waters for the next few days as weak low pressure will maintain south wind generally less than 15 knots. There will be a mix of wave trains with varying periods...out of the northwest...and SW with the overall wave heights gradually building tonight. Sea heights of 5 to 7 feet can be expected through Thursday. High pressure will rebuild over the waters Friday and Sat...with thermal low pressure over the coast and coastal waters. This will bring another round of north winds to the waters this weekend with winds possibly reaching Small Craft Advisory levels at times. Tj && Pqr watches/warnings/advisories... or...none.
