In the upper atmosphere a strong ridge of high pressure has developed up in the eastern Pacific and the Gulf of Alaska with a cold trough extending from north-central Canada into southern California. This leaves the Pacific Northwest in a cold northerly flow aloft. Computer models indicate one disturbance in this northerly flow will move through the region Sunday afternoon and evening with another following Monday night and early Tuesday. The latest model runs are also more aggressive with the potential for significant low level snow, especially in northern sections. Some light accumulation (less than an inch) is possible in valley locations the north Sunday night and early Monday. For southern zones the snow level will likely be about 2500 feet and above for Monday. Mountain locations will generally receive 2-4 inches of new snow through Monday evening. <o:p></o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:10.0pt;font-family:"Courier New"'>Smoke dispersal conditions will be generally fair with most areas seeing a southwesterly transport wind, but a northerly component to the transports will develop in the northern zones. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'> EXTENDED OUTLOOK (TUESDAY – THURSDAY)<o:p></o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:10.0pt;font-family:"Courier New"'>The upper disturbance that moves through Monday afternoon and evening has the potential to be a significant snow producer for virtually all of western Oregon. Snow levels will reach to all elevations of interior western Valleys. Accumulations depend on the amount of available moisture. As mentioned above, latest model runs are more aggressive with snow amounts. At the high end, 2-4 inches is possible late Monday in the Willamette Valley with greater amounts at higher elevations. Drier air will filter into northern sections to end the snow Tuesday. Southern valley locations could see 1-3 inches during the day on Tuesday. Smoke dispersal conditions will be mostly fair to good throughout western Oregon.<o:p></o:p></span></p><p class=MsoNormal style='margin-left:.5in'><span style='font-size:10.0pt;font-family:"Courier New"'>For Wednesday and Thursday, the cold upper trough will move east and the ridge in the Pacific will begin to move over the area. Upper flow will be northerly and dry for mostly sunny weather. Temperatures, however, will remain cool. Cold nighttime temperatures will promote overnight inversions that will be slow to break and limit maximum mixing heights. Thus smoke dispersal conditions will be marginal Wednesday and beyond. </span><span style='font-size:10.5pt;font-family:"Courier New"'><o:p></o:p></span></p><p class=MsoPlainText><span style='font-family:"Courier New"'>2.
