DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Mild weather in store for the area. Upper level flow generally westerly. A weak short-wave trough slides over the area Friday afternoon. Not much associated with this feature other than a few clouds and enough decrease in stability to keep mixing good over northeast Oregon. Low level winds light northwest to north. In general good smoke dispersion during the day but mostly clear skies will allow rapid stabilization after sunset and poor nighttime mixing. OUTLOOK (SATURDAY - MONDAY): Over the next few days, a gradual strengthening of the upper ridge will continue the pleasant weather. Only drawback 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. DISPERSION FRIDAY Mixing height 2400 - 3400 ft during the morning. Afternoon mixing height rises to 4500 - 5000 ft or more, then lowers to 2000 - 3000 ft during the evening. Overnight mixing becomes very poor. Transport wind NW to N at 5 - 9 mph in the morning, NW to N at 8 - 14 mph during the afternoon and, NNW to N at 11 - 23 mph during the evening. Surface wind NW to N at 4 - 8 mph during the morning, becoming NW to N at 9 - 15 mph during the afternoon and evening. OUTLOOK: SATURDAY Mixing height below 1000 ft early, rising to 3300 to 4300 ft by late morning, and 4200 to 5000 ft during the afternoon. Transport wind NNW to NNE at 7 - 11 mph during the morning, becoming NNW to N at 10 - 22 mph during the afternoon. Surface wind light and variable, becoming NW to N at 10 - 16 mph during the afternoon. SUNDAY Mixing height below 1000 ft early, 3000 to 4000 ft by late morning, and 4000 to 5000 ft during the afternoon. Transport wind NW to NNE at 6 - 10 mph. Surface wind light and variable, becoming NW to N at 4 - 8 mph during the afternoon. MONDAY (Memorial Day) Mixing height below 1000 ft early, rising to 2900 to 3900 ft by late morning, and 3800 to 4800 ft during the afternoon. Transport wind NW to NNE at 6 - 10 mph.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Weak ridging continues to build slowly. A minor short-wave crosses the area, weakening the ridge temporarily. Looks pretty insignificant but the wave could destabilize the upper levels just enough for afternoon heating to trigger a thunderstorm or two. In the lower levels, enough stability remains that mixing will be slightly limited. As the trough moves away and the sun sets, a strong surface inversion sets up and mixing height falls. After some variability in the morning transport, it settles to brisk northwest to north. Biggest problems will be units that could smolder into the night, and the upcoming Memorial Day weekend. Recommend backing off from burning near SSRAs or recreation areas for the weekend. OUTLOOK (SUNDAY - TUESDAY): As the short-wave drifts east, the air mass gradually stabilizes. Heating will provide good mixing during the afternoons but overnight mixing becomes very poor and smoke will tend to flow down drainages. Light overnight surface winds don't help either. Chances of thunderstorms decrease but still cannot be totally ruled out. As mentioned above, recommend holding off burning through the weekend due to both dispersion and the holiday. 2. DISPERSION SATURDAY Mixing height 2500 - 3500 ft during the morning, 3800 - 4800 ft in the afternoon, lowering to 1000 - 1800 ft during the evening and less than 1000 ft overnight.

Surface wind NW to N at 4 - 8 mph during the morning and NW to NNW at 9 - 15 mph during the afternoon and evening. OUTLOOK: SUNDAY Mixing height below 1000 ft early, 3100 to 4100 ft by late morning, and 4100 to 5000 ft during the afternoon. Transport wind NW to N at 7 - 13 mph in the morning and NNW to N at 12 - 24 mph during the afternoon. Surface wind light and variable, becoming NW to NNW at 9 - 15 mph during the afternoon.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 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.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Upper level ridge will remain in place through Saturday with the axis of the ridge near the Oregon/Idaho border. Expect continued summer-like weather. Air mass will remain stable except for brief afternoon instability inland due to daytime heating. Some thunderstorm buildups will continue in the afternoon to evening - mainly to the south. Wind flow will remain weak and favor generally a NW to N flow. Smoke dispersion will remain poor to fair. OUTLOOK (SUNDAY - TUESDAY): Upper level ridge starts weakening on Sunday as a trough moves down from the north and an upper low approaches from the southwest. However, expect continued warm and dry conditions. Thundershower threat will get pushed mainly southward. Eventually the upper level low in the eastern Pacific and to the southwest of the state will move close enough to bring increased clouds and maybe some moisture over the region on Tuesday. Wind flow will remain light and mostly northerly Sunday and Monday. As the low approaches Tuesday, wind flow appears it will turn lightly offshore. Smoke dispersion will remain poor to fair. 2. DISPERSION SATURDAY Mixing height below 1000 ft early, rising to 2500 - 3500 ft by late morning. Afternoon mixing height rises above 5000 ft then lowers below 1000 ft during the evening.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Upper level ridge will weaken over the next couple of days as an upper low approaches from the southwest and a trough drops down from the north. Southerly flow aloft will continue the thundershower threat over the region but mainly to the south. Air mass will remain stable and smoke dispersion mostly poor due to little wind movement. Otherwise expect mostly fair skies. OUTLOOK (MONDAY - WEDNESDAY): Upper level trough moves in closer on Monday and Tuesday. However, expect little change in the weather other than slightly cooler temperatures. Isolated afternoon to evening thundershowers are still possible. Expect little change to the air mass with stable mornings and unstable afternoons due to heating. Wind flow will remain fairly light favoring NW to NE flow. Smoke dispersion will remain poor to fair. 2. DISPERSION SUNDAY Mixing height below 1000 ft early rising to 1800 - 2800 ft by late morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 An upper level ridge centered over the northern Great Basin will keep conditions warm into the first part of next week. Southerly flow will continue to produce enough moisture for the threat of afternoon and evening thunderstorms mainly over the Cascades. Nighttime inversions will hold smoke close to the ground overnight and into the morning hours. During the afternoon mixing heights will improve smoke dispersal conditions to good most areas. OUTLOOK (TUESDAY - THURSDAY): The upper level ridge slips slowly eastward and an upper level low moves slightly closer to the California coastline on Monday. Upper flow will continue to bring moisture northward for the threat of afternoon and evening thunderstorms. The upper low remains off the California coast through the outlook period. Afternoon instability will help smoke dispersion, but the window for acceptable smoke dispersal conditions remains narrow with marginal conditions evenings and mornings. 2. DISPERSION MONDAY Zone 630 and 632: Mixing height 3900 - 4900 ft during the morning. Afternoon mixing height lowers to 3100 - 4100 ft then lowers below 1000 ft during the evening. Transport wind NNE to ENE at 4 - 8 mph during the morning. Transport wind increases to NNE to ENE at 12 - 24 mph during the afternoon and increases to NNE to ENE at 15 - 29 mph during the evening. Surface wind light and variable and controlled by local terrain during the morning. Surface wind increases to NNW to NNE at 9 - 15 mph during the afternoon and evening. Zone 633 - 638: Mixing height 3500 - 4500 ft during the morning. Mixing height rises above 5000 ft during the afternoon then lowers below 1000 ft during the evening. Transport wind N to ENE at 4 - 8 mph during the morning. Transport wind increases to N to NE at 10 - 20 mph during the afternoon and evening. Surface wind NW to N at 4 - 8 mph during the morning.
