DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 The upper ridge that provided several days of sunny and warm weather to the Pacific Northwest will have moved to the northern plains states by Tuesday and an upper level low will be moving into British Columbia. A broad upper level trough will cover Oregon and Washington. This will produce showers in portions of the state, but south-central Oregon may escape any significant rain. Cooler air aloft will give high mixing heights and good to excellent smoke dispersal conditions. OUTLOOK (WEDNESDAY - FRIDAY): Temporary weak ridging will return to the region Wednesday to begin a period of generally dry weather. Afternoon mountain showers are a possibility. Mixing should remain high for favorable smoke dispersal conditions. By Thursday a thermal trough will develop and move into southwestern Oregon. This will give northeasterly transport winds to the region.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Sunny and warm weather on tap for the area. Upper level flow generally westerly. Although a weak short-wave trough slides into the Pacific Northwest Friday afternoon, it will have little impact on the area. Low level winds light west northwest to north. In general good smoke dispersion during the day. Rapid stabilization of the air mass after sunset and light surface wind will necessitate avoiding smoldering units near SSRAs. OUTLOOK (SATURDAY - MONDAY): Over the next few days, the upper ridge will gradual strengthen and will continue the pleasant weather. The downside of this is that mixing height gradually lowers as the air mass becomes more stable. Daytime heating will yield good afternoon mixing but mixing height plummets after sunset. Smoldering units will need to be avoided near SSRAs. May need to gradually back off on burning as the air mass continues to stabilize into the holiday weekend. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Weak ridge over the area. A minor short-wave crosses to the north. Still, when the influence of this trough combines with afternoon heating, there exists the slightest chance of afternoon thunderstorms. In the lower levels, the air mass just stable enough that mixing will be slightly limited. Overnight a strong surface based inversion brings the mixing height down to less than 500 feet. Transport wind light in the morning, then increases from the northwest. Biggest are nighttime smolder, poor dispersion except in the heat of the afternoon, and the upcoming Memorial Day weekend. Recommend backing off from burning near SSRAs or recreation areas for the weekend. OUTLOOK (SUNDAY - TUESDAY): Over the weekend, the air mass continues to gradually stabilize. Heating will provide good mixing in the afternoons but overnight mixing becomes very poor and smoke will tend to settle into the Basin. Light overnight surface winds don't help either. Chances of thunderstorms decrease but still cannot be totally ruled out for Sunday afternoon. As mentioned above, recommend holding off burning through the weekend due to both dispersion and the holiday. 2. DISPERSION SATURDAY Mixing height 2300 - 3300 ft during the morning.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 West to southwest flow aloft over the Pacific Northwest brings warm dry weather to Oregon. Afternoon heating creates enough instability that there will be a slight chance of thunderstorms. Light north to northeast transport continues. Surface winds light and variable much of the day, so terrain a major factor in smoke movement. Poor night and morning dispersion but heating brings generally good dispersion in the afternoon. OUTLOOK (MONDAY - WEDNESDAY) Not a lot of change through mid-week. The upper level ridge tends to strengthen, thus limiting mixing. Transport flow mostly northerly through the period with considerable variability under the subsiding air aloft. Generally light surface wind complicates keeping smoke out of sensitive areas. Poor dispersion in the mornings but heating will provide good dispersion during the afternoons. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 The Pacific Northwest will remain under a generally west-southwest flow aloft on Tuesday. A weak front will move across Washington, but be too far away to have any effect on this area. Mixing heights should be favorable for good smoke dispersal. Transport winds will be generally northwesterly. OUTLOOK (WEDNESDAY-FRIDAY) Weak ridging aloft will continue the dry weather for the area on Wednesday. Transport winds will be generally northerly. Mixing heights still providing good smoke dispersal conditions. However nighttime inversions will hold residual smoke close to the ground during the early morning hours. Thursday and Friday the ridge sharpens a bit with its axis to the east for more southerly flow over the region. This could allow isolated thunder storms over mountainous areas. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 The jet stream shifts northward on Wednesday as high pressure builds aloft. Dry weather will prevail across the entire Pacific Northwest. Temperatures should be up about five degrees from Tuesday. Mixing heights will be high and smoke dispersal conditions will be good to excellent, but nighttime inversions will hold residual smoke close to the ground. OUTLOOK (THURSDAY-SATURDAY) The upper level high pressure area continues to build. The high center will be over the Great Basin and clockwise flow around the high could bring some moisture north for the possibility of afternoon or early evening thunderstorms Thursday and Friday, mainly over mountainous areas. Mixing heights will remain favorable for good smoke dispersal conditions. A weather system moving across British Columbia flattens the ridge Friday and turns upper flow more southwesterly with lessons the chance for thunderstorms. 2.
