DISCUSSION. An unusual patter with the fog and low stratus unfolded today with clearing in the Roseburg area, but remaining through the day in Northern California and east of the Cascades. The stratus should move in quickly around or shortly after sunset to similar locations as last night/this morning. The only mix in the scenario is the approaching front later Tuesday morning, although the current timing with the current cloud cover suggests that the inversions will remain in place until the front moves inland and starts to mix the lower atmosphere with increased mid to upper layer clouds and winds. The front moves inland Tuesday with the right entrance region of an 85 kt jet seeping through. this front stretches well south of the region with a northwesterly jet extending well south to offshore of the southern California coast. Showers behind the front slowly taper off with weak ridging building in ahead of the next system that moves in Wednesday afternoon.
As we head into Thursday IVT models continue to indicate a weak atmospheric river event as the front stalls over the Pacific Northwest Through Thursday night. This system will see a westerly 150 kt jet sitting overhead for most of the duration of the event, but BL winds will not be as strong feeding low level moisture into the region. However, with the weaker low level winds the precipitation will not be a strong orographically influenced, and areas north of the Siskiyous will not be as strongly rain shadowed. In the continued zonal flow pattern and westerly winds pretty much up the column, showers will continue into at least Friday evening as the axis of the jet wobble north and south over the forecast area. There is showing just a brief break in the action Friday night into early Saturday morning before the next system moves in. Snow levels drop on the tail end of the exiting system prior to this, but precipitation amounts are looking low. Sven
AVIATION. For the 10/00Z TAFs . A mix of IFR/MVFR ceilings and local stratus/fog are still impacting portions of the Illinois, Scott and Shasta Valleys as well as some of the valleys east of the Cascades, including near Klamath Falls. These areas will likely hold onto the low conditions through Tuesday morning. It did manage to clear to VFR in Roseburg and Medford this afternoon, but MVFR stratus held at North Bend. The valley locations that did clear this afternoon will see a few hours of VFR into this evening, but IFR/LIFR stratus/fog will likely return late this evening and continue overnight into Tuesday morning. A frontal system will arrive at the coast Tuesday morning with some light precipitation moving in west of the Cascades in the afternoon/evening, then shifting east of the Cascades at night. This will produce areas of MVFR and terrain obscuration. -Spilde
MARINE. Updated 230 PM PST Monday, 9 December 2019 . Weak high pressure will persist over the waters this afternoon with light winds into early evening. South winds will increase tonight and seas will become steep early Tuesday morning ahead of a cold front. Latest data suggests winds won't quite reach Small Craft Advisory criteria, but the combination of gusty south winds and west swell will create conditions that are hazardous to small craft. The front will be the start of a new series of disturbances. A stronger front with increasing south winds will likely arrive Wednesday while a high and steep long period west swell builds late Wednesday into Friday. We now have high confidence in the west swell reaching at least 16 feet at 16 seconds which will impact some bar crossings and crab pots. Keene

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
