Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Updated Aviation Section.
DISCUSSION. The marine layer is mostly offshore this evening, except it is hugging the immediate coast near Cape Arago, where it'll likely remain overnight. Offshore flow is redeveloping south of Cape Blanco, so expect it to stay clear there overnight. Some low clouds/patchy fog could develop in the Umpqua Valley toward sunrise, but these should be short-lived. Other than some high clouds inland, it'll be another clear and chilly night with the lowest temperatures down in the teens and low 20s east of the Cascades/northern CA.
After the chilly start, another sunny, warm late February afternoon is expected Thursday with highs again widely in the 60s. Some readings near 70 are possible in the inland west side valleys south of the Umpqua Divide. Highs in the mid to upper 70s are expected in the lower Klamath River Valley of SW Siskiyou County. We're going with a high of 69 degrees here in Medford; and 60-64 degrees in Roseburg, Klamath Falls, Lakeview and Alturas. -Spilde
AVIATION. For the 27/06Z TAF Cycle . VFR ceilings/visibility will continue through the TAF period. The exception will be in portions of the Umpqua Basin and along the Coast. Low ceilings and fog will be possible in these locations tonight. If fog and low stratus is able to form LIFR conditions are possible around the locations mentioned above. Otherwise the fog and stratus should clear up pretty quickly after sunrise and VFR conditions will prevail shortly after sunrise as the boundary layer dries out.
MARINE. Updated 800 PM PST Wednesday 26 Feb 2020 . Moderate north winds and building west swell will generate steep seas south of Cape Blanco across all the waters late tonight through Thursday night. Conditions will improve briefly Friday, then a cold front will move onshore Friday night. The front Friday night doesn't look strong, so seas will remain swell dominated through Saturday. Strong north winds are expected Sunday and seas will likely increase to 10 feet with a shorter period as wind waves become more dominant. The active weather pattern will likely continue into next week as a thermal trough forms builds up the coast yet again.
PREV DISCUSSION. /Issued 850 PM PST Wed Feb 26 2020/
SHORT TERM . (Tonight through Saturday night) Satellite imagery are showing mainly clear skies across southern Oregon and northern California. For those of you in the Rogue Valley looking west of Talent/Ashland seeing that large plume of smoke, it is visible on the visible imagery, but other indicators traditionally used on other satellite channels are not showing up. Overall, the benign weather will continue through Friday morning with tonight being similar to last night, and tomorrow morning to be another chilly one with low clouds expected in the Illinois, Umpqua and Coquille Valleys.
A front will then come in Friday afternoon, moistening up the atmosphere, and bringing in some light precipitation to the Coast, Coast Range and areas north of the Umpqua Divide. This front will be accompanied with several impulses, with the second impulse (short wave) bringing in another wave of moisture and bring precipitation to more areas west of the Cascades on Friday night into Saturday. This front will continue to dig southward before becoming a closed upper level low pressure system as we transition into the long term discussion. This will keep allowing waves of light precipitation to move across southern Oregon and northern California.
In the mean time, this frontal system will be ushering in colder air into our forecast area. This will also cause snow levels to lower from 6000 feet on Friday to 4000 feet on Friday night to 2500 feet or so on Saturday to around 1500 feet on Saturday night. This means that there will be a chance for a few flakes on the Valley Floors in snow showers on Saturday night, but impactful snow is not expected for the Valley Floors at this time. Snow amounts on the passes will be up to 2 inches on some of the higher passes with more of a dusting on the lower passes. Overall, this system does not appear to be impactful at this time, but keep an eye on the forecast in case things change. -Schaaf
LONG TERM . Sun 30 Feb through Wed 03 Mar 2020.
A long wave trough will be over the west coast states at the beginning of the extended, supporting a post-frontal showery scenario. However, the showers will be light, with most of the west side seeing light precipitation and most east side locations likely seeing trace or no precipitation.
The trough will dig into the intermountain states and shear Sunday into Sunday night, leaving a cutoff low over southern California Sunday night. During this evolution, the flow aloft over the Medford CWA will become northeasterly. Showers will end Sunday and the low level flow will turn easterly, drying out the air mass.
The easterly flow event will be short-lived, as a short wave will ride over the offshore ridge, moving onshore Monday. The associated front will be quite weak, and it will also move onshore Monday. Once again, the precipitation will be light and most of it will fall from the Cascades west. Post-frontal showers will spread to the east side Monday night into Tuesday. Curiously enough, the NBM output suggests that the precipitation will be heavier with this front over inland locations west of the Cascades, perhaps because this front will linger over the area with showers persisting into Tuesday night. Still, the precipitation will be light. This trough will also dig into the intermountain states Tuesday night, but it won't shear, continuing to progress east. Flow aloft over the Medford CWA will remain northwesterly with a strong long wave ridge offshore through the remainder of the extended period.
The deterministic GFS and EC solutions differ a bit from Tuesday night on, as the GFS brings another short wave over the ridge onshore Tuesday night, while the EC has no short wave activity. Accordingly, the GFS supports continued shower activity into Wednesday while the EC dries things out. Going with FB here, which went with a compromise solution here.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
