Synopsis for the southern oregon coastal waters..Gusty north winds and steep to very steep seas will continue through Thursday evening as the thermal trough persists along the coast. The strongest winds are south of gold beach, and gale force gusts are possible offshore of brookings this evening. Conditions will improve Friday as the thermal trough weakens. Relatively calm conditions are then likely Friday night into early next week, although a low, long period south swell could result in problematic bar conditions this weekend.

Area Forecast Discussion National Weather Service Medford OR 901 PM PDT Wed Jul 1 2020

DISCUSSION. Satellite imagery shows some stratocumulus near the border of Coos and Curry County with mainly clear skies elsewhere. The marine layer will push back into the coast, Coquille, and Umpqua Valleys bringing some stratus clouds with it. Otherwise, expect the clear skies to continue elsewhere.

Tonight will be very similar to last night, with portions of the east side (especially near Lakeview and north of Klamath Falls) to see widespread areas of hard frosts. For Klamath Falls and Tulelake, it appears that frost will be probable, although it won't be as hard as for areas north of the area. Have issued a frost advisory anyway for Lakeview, Tulelake, Merrill, Bly, Bonanza, and the outskirts of Klamath Falls for tonight. Please prepare for frost conditions on any sensitive plants.

Other changes to the forecast were to lower the minimum temperature for tonight to be in line with the areas of expected frost. For more details on the full forecast, please read the discussion below. -Schaaf

MARINE. Updated 800 PM PDT Wednesday 1 July 2020 . Gusty north winds and steep to very steep seas will continue through Thursday evening as the thermal trough persists along the coast. The strongest winds with very steep and hazardous seas are south of Gold Beach. There will be little fluctuation in conditions with winds remaining strongest and seas highest during the afternoon and evening hours. But, there will be a detectable peak in winds and seas this evening with gale force gusts possible offshore of Brookings. Conditions will improve as the thermal trough weakens Friday, with Small Craft Advisory conditions retreating to areas south of Cape Blanco. Relatively calm conditions are then likely Friday night into early next week, although a low, long period southerly swell is expected later Friday through the weekend, which could result in problematic bar conditions and increased sneaker wave risk. The thermal trough will return next week, but models are showing it taking up a more inland position. This would keep north winds in place over the area, but at a much weaker strength than during a typical event. -DW/BPN

PREV DISCUSSION. /Issued 519 PM PDT Wed Jul 1 2020/

UPDATE . Updated the aviation section.

AVIATION . For the 02/00Z TAF Cycle . Gusty winds continue for most areas early this evening, along with mountain wave turbulence downwind of ridgelines and across the East Side. Another round of MVFR ceilings are expected after 04Z tonight along the coast and into the coastal waters, and are likely to develop in the Umpqua Basin later tonight as well. The coastal and Umpqua low clouds will gradually dissipate after sunrise Thursday morning. Otherwise, skies will remain clear into Thursday evening. -DW

PREV DISCUSSION . /Issued 235 PM PDT Wed Jul 1 2020/

DISCUSSION . Not much change in the forecast given the "troughy", stable, cool pattern that dominates the forecast period. We are anticipating another marine push that will bring overcast conditions to the coast north of Cape blanco, the Umpqua Basin, and into Jackson and Josephine counties. There is moderate confidence that fog in western and northwestern Douglas county will develop, certainly along the lower parts of ridges. Low confidence of fog in Coos county and over the coastal waters, more likely a low stratus ceiling will develop.

This persistent west-southwest flow aloft will translate to breezy winds at the surface, but drying throughout the mid-levels. This has resulted in an almost total reduction of thunderstorm possibilities for Lake county. Most likely on saturday, there will be some cumulus buildup that will move east-northeast, with development after moving well away from Lake county.

Ensemble systems are in fair agreement that a broad trough will pass through Washington on Sunday. This will cool the region back down some after peak warming on Saturday. It can be expected that the marine layer will once again influence the area and that afternoon winds will be stronger than those this Friday and Saturday. -Miles

MARINE . Updated 200 PM PDT Wednesday 1 July 2020 . Gusty north winds and steep to very steep seas will continue through Thursday evening as the thermal trough persists along the coast. The strongest winds with very steep and hazardous seas are south of Gold Beach. There will be little fluctuation in conditions with winds remaining strongest and seas highest during the afternoon and evening hours. But, there will be a detectable peak in winds and seas early Wednesday evening with gale force gusts possible offshore of Brookings. Conditions will improve as the thermal trough weakens Friday, with Small Craft Advisory conditions retreating to areas south of Cape Blanco. Relatively calm conditions are then likely Friday night into early next week, although a low, long period southerly swell is expected later Friday through the weekend, which could result in problematic bar conditions and increased sneaker wave risk. The thermal trough will return next week, but models are showing it taking up a more inland position. This would keep north winds in place over the area, but at a much weaker strength than a typical event. -BPN/Smith

FIRE WEATHER . Updated 200 PM PDT Wednesday, 1 July 2020 . The main concern for the forecast period will be gusty afternoon winds with lower relative humidity along, and east of the Cascades into this evening, and will be strongest over the ridges. Were not expecting winds to be strong, but enough where it will be noticeable. We'll maintain the headline in the fire weather forecast.

Additionally, gusty northeast winds are expected along the mid slopes and ridges in fire zones, 618, 619 and western 620 tonight into Thursday morning. Overnight recoveries should be moderate tonight into Thursday morning.

Aside from the winds, it's looking like a relatively quiet fire weather pattern for at least the next 7-10 days. The general pattern will feature troughiness over the area with a stable northwest, then southwest flow. This typically results in temperatures around or slightly below normal and no precipitation. A warm up is expected Thursday through early next week. Even then, afternoon temperatures are expected to be near normal for this time of the year.

Thunderstorm chances are next to zero through the forecast period. This is because of generally stable and dry northwest to southwest flow aloft and drier mid level moisture. A upper trough will move into the area by the start of next week with a weak trigger, but once again mid level moisture is lacking, thus no threat of thunderstorms.

Beyond next Monday the operational models, ensemble members and cluster analysis all point to a similar conclusion. General troughiness with continued dry and stable conditions. -Petrucelli/Keene
