DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A weather disturbance is forecast to rotate through a broad upper-level trough over Washington and Oregon, bringing a chance of showers to the northern zones. Skies will be partly to mostly cloudy over the southern zones. Maximum temperatures will be 10-15 degrees below normal with strong onshore flow. Smoke dispersal conditions should be fair to good. OUTLOOK (SATURDAY-MONDAY) A few showers could persist over the northern zones through Saturday morning, with at least partly cloudy conditions across the southern zones. A drier and progressively warmer northwesterly flow aloft is forecast Saturday afternoon through Monday, as the upper-level trough progresses east of the region. Subsidence will suppress mixing heights slightly, especially north, but smoke dispersion should remain fair to good. The strong onshore flow will turn more northerly Saturday and Sunday, especially over the southern zones. With increasing sunshine, temperatures will recover to within about 5 degrees of normal Saturday and to near normal on Sunday. By Monday an upper-level ridge is forecast to approach the coastline with transport winds turning northerly and perhaps offshore, especially south. Temperatures should climb above normal under mostly clear skies. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY An upper-level trough will slowly push east of the region. A very weak disturbance is forecast to move across western Oregon, in the drying northwesterly flow aloft. That will maintain some cloudiness across mainly the northern zones with a slight chance of morning showers over the higher terrain. Skies will begin clearing in the afternoon, as warming aloft begins to stabilize the atmosphere. Transport winds will remain onshore but should turn more northerly, especially across the southwestern zones. Temperatures will begin to recover but remain below normal. Smoke dispersal conditions should be fair to good. OUTLOOK (SUNDAY-TUESDAY) A dry northwesterly flow aloft is forecast to continue through Monday. Subsidence, associated with an approaching ridge of high pressure, will suppress mixing heights slightly, especially north, but smoke dispersion should remain fair to good. Continued onshore transport winds will turn more northerly by late Monday, and temperatures will warm to near normal. By Tuesday an upper-level ridge is forecast to build strongly enough over the region to turn the transport winds offshore. That may allow for burning in areas of the coastal range. It will also warm temperatures to above normal, and significantly drop humidity levels, under mostly clear skies. The offshore flow may continue on Wednesday, with the latest long-range computer models showing a return to onshore flow, and cooler temperatures, on Thursday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper air charts show a strong ridge aloft extending from about 600 miles west of northern California northward into the Yukon. This gives a dry northerly to northwesterly flow aloft over the region. At the surface a strong thermal trough extends from the central valley of California into southwest Oregon. A strong, generally northerly or northeasterly pressure gradient has set up. Morning soundings from Salem and Eugene show low level inversions. However with quite warm surface temperatures today any inversion should easily be broken for mixing heights rising to well above 5000 feet in the afternoon. Winds will be quite brisk today and wind precautions need to be observed. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2000 - 3000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY Upper air charts show a strong upper ridge offshore again tomorrow with a thermal trough extending from central California into SW Oregon. Low level flow will continue offshore except for light onshore flow developing at the extreme south coast. Temperatures in the interior will be from 15 to 20 degrees above average for the time of year...the warmest weather since last summer. Temperatures on the coast will be 10 to 15 degrees above average except temperatures will be near average on the south coast. Winds will be from the East in the north and from the southeast most southern zones. Maximum afternoon mixing heights will be well above 5000 feet for generally good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The surface thermal trough builds northward then shifts onshore during the day on Thursday. Low level flow will turn onshore most coastal areas except the extreme north. Temperatures will be near average for the coastal strip except near Astoria where temperatures will again be about 10 degrees above average. Interior locations will also again be about 15 to 20 degrees above average. With cooler temperatures on the coast but continued warm air aloft, maximum mixing heights will not be as high Thursday. Elsewhere mixing heights will remain high, but winds will be light and variable in much of the interior for a more difficult burning environment. The upper ridge flattens Friday and transport winds become more north or northwesterly except for southern zones where light and variable winds will continue. Temperatures cool to 8 to 14 degrees below average at interior locations. With warm temperatures aloft the atmosphere will be a little more stable than on Thursday with only marginal smoke dispersal conditions over the south coast range and fair to good conditions other areas. By Saturday a weak upper trough will reinforce the onshore flow and temperatures will drop a few more degrees although remain 3 to 9 degrees above average for most interior locations. Smoke dispersal conditions will be fair to good with highest mixing heights over the Cascades, but peaking at only about 3000 feet for the coast range. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY Upper air charts show a strong upper ridge offshore again tomorrow with a thermal trough extending from central California into SW Oregon. Low level flow will continue offshore except for light onshore flow developing at the extreme south coast. Temperatures in the interior will be from 15 to 20 degrees above average for the time of year...the warmest weather since last summer. Temperatures on the coast will be 10 to 15 degrees above average except temperatures will be near average on the south coast. Winds will be from the East in the north and from the southeast most southern zones. Maximum afternoon mixing heights will be well above 5000 feet for generally good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The surface thermal trough builds northward then shifts onshore during the day on Thursday. Low level flow will turn onshore most coastal areas except the extreme north. Temperatures will be near average for the coastal strip except near Astoria where temperatures will again be about 10 degrees above average. Interior locations will also again be about 15 to 20 degrees above average. With cooler temperatures on the coast but continued warm air aloft, maximum mixing heights will not be as high Thursday. Elsewhere mixing heights will remain high, but winds will be light and variable in much of the interior for a more difficult burning environment. The upper ridge flattens Friday and transport winds become more north or northwesterly except for southern zones where light and variable winds will continue. Temperatures cool to 8 to 14 degrees above average at interior locations. With warm temperatures aloft the atmosphere will be a little more stable than on Thursday with only marginal smoke dispersal conditions over the south coast range and fair to good conditions other areas. By Saturday a weak upper trough will reinforce the onshore flow and temperatures will drop a few more degrees although remain 3 to 9 degrees above average for most interior locations. Smoke dispersal conditions will be fair to good with highest mixing heights over the Cascades, but peaking at only about 3000 feet for the coast range. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY A weak upper-level trough will approach the southern Oregon and northern California coast with increasing light southerly flow aloft over southwestern Oregon. The surface thermal trough will shift into the western interior around midday with mostly northerly transport winds along the coast and over the coast range. Transport winds may turn slightly onshore in the afternoon, especially in the western zones, as the surface thermal trough shifts eastward to over the Cascades. Near record high temperatures are likely east of the coastal range crest, especially across the northern zones. Cooler low-level marine air will begin seeping inland and will act to suppress afternoon mixing heights across the coastal range, especially south. Higher mixing heights should prevail over the Cascades. Smoke dispersal conditions should be generally fair to good, but watch for transport winds shifting to more onshore in the afternoon, especially across the western zones. OUTLOOK (FRIDAY-SUNDAY) A weak upper-level trough will move over Oregon Friday and force the surface thermal trough east of the Cascades. Some morning clouds could briefly penetrate east of the coastal range. Inland temperatures will remain above normal, but increasing onshore flow will likely provide several degrees of cooling compared to Thursday. A dry north to northwesterly flow aloft is forecast for Saturday and Sunday with weak onshore flow maintaining above normal temperatures and fair to good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A broad-scale upper-level ridge of high pressure will remain over the Pacific Northwest. However, a very weak upper-level trough will move over Oregon and force the surface thermal trough east of the Cascades. That will turn the wind-flow onshore and initiate a surge of cooler marine air inland to the Cascades. Temperatures will remain well above normal. The cooler marine air will act to suppress afternoon mixing heights across the coastal range. Afternoon mixing heights should be relatively high over the Cascades. Smoke dispersal conditions should be generally fair to good. Watch for transport to shift onshore and increase in the afternoon. OUTLOOK (SATURDAY-MONDAY) The upper-level ridge axis will be offshore with a dry north to northwesterly flow aloft over the weekend. A gradual flattening of the upper-level ridge will increase the northwesterly flow aloft by Monday. Increasing onshore transport winds will lower temperatures to near normal, by Monday, with mildly suppressed mixing heights over the western zones. Expect fair to good smoke dispersal conditions during the outlook period. 2.

This will be the last regularly scheduled smoke management forecast for western Oregon for the 2010 spring burning season. With the hot weather and many areas now in fire season we do not anticipate any significant prescribed burning form this point through the summer. Clearances for any burning still planned can be handled individually with a phone call to the duty forecaster at 503-945-7401. Smoke management forecasts and instructions will resume this fall when conditions are again conducive to prescribed burning. 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY The strong upper-level ridge of high pressure that has been over the Pacific Northwest will shift offshore with an increasing north to northwesterly flow aloft over Oregon. That will turn the low-level winds weakly onshore and initiate a cooling trend across the interior of western Oregon. Morning marine low clouds could penetrate through some of the coastal mountain gaps with mostly sunny skies expected in the afternoon. Temperatures will remain well above normal but will back away from the near-record highs of the past three days. The cooler marine air will act to suppress afternoon mixing heights across the coastal range, but afternoon mixing heights should remain relatively high over the Cascades. Smoke dispersal conditions will be fair to good. OUTLOOK (SUNDAY-TUESDAY) The upper-level ridge axis will remain offshore with a continued dry northwesterly flow aloft during the extended forecast period and perhaps through all of next week. A fairly strong trough is forecast to cut across southern British Columbia on Monday, which will drive a dry cold front through the region. Increasing onshore transport winds will lower temperatures to near normal and maintain mildly suppressed mixing heights west of the Cascades. Onshore surface winds could become quite gusty across the eastern zones Monday afternoon. Other than a chance of morning drizzle over the northern coastal range, dry conditions should prevail with afternoon clearing each day. Expect fair to good smoke dispersal conditions during the outlook period. 2.
