Synopsis for the southern oregon coastal waters..Weak high pressure will build into the waters today with improving conditions into Monday. Seas are likely to become steep Tuesday morning ahead of a cold front. The front will be the start of a new series of disturbances with steep seas possibly affecting the waters through the end of the week. This includes the potential for a high and steep long period west swell on Thursday.

Area Forecast Discussion National Weather Service Medford OR 401 AM PST Sun Dec 8 2019

DISCUSSION. 2:30 AM radar is showing some very light showers over the Rogue Valley and Cascades in Oregon and also across southeastern Siskiyou County and Modoc County. This is in relation to a weak area of low pressure moving across northern California. This low is best seen in the upper level water vapor satellite imagery, despite the actual circulation appearing pretty messy.

These showers will continue this morning as the low moves farther east. Then, the shower activity will largely decrease throughout the day as a ridge of high pressure moves in its place. This means that the inversion will likely set up tonight with valley fog setting up tonight. Some areas may even see that fog become dense. This pattern will continue again through Monday with relatively mild weather and chilly nights.

Then, on Tuesday and Wednesday, a weak frontal system will move across southern Oregon and northern California. This will weaken the ridge; but will likely mean very little in the way of precipitation except for areas near the coast and the Coast range. Some areas of the Umpqua basin may also see some light rain as well. The important part of the front will be weakening the ridge to more of a zonal flow which will allow multiple fronts to approach our area in quick succession.

The first of these fronts will arrive Thursday night. This front will bring some light to moderate precipitation with it. Snow levels will increase ahead of the front again and be much higher than the previous storm (looking at snow levels around 7000-8000 feet). Some areas near the coast may even see some periods of heavy precipitation on Thursday night and Friday.

The next system will arrive on Saturday bringing another shot of moderate to locally heavy precipitation with it. Snow levels will start to fall as this front will bring in colder air, but most of the precipitation will start as rain for the passes. Snow levels will quickly drop to around 4000 feet by Saturday night and to around 3000 feet by Sunday night. By this time, the precipitation will become more showery in nature. Confidence in the details of this system are pretty low since model and ensemble spread is very large; but it is safe to mention that this storm system should continue to be monitored as it brings a higher chance for travel impacts next weekend. -Schaaf

AVIATION. For the 08/12Z TAFs . Showers will continue to taper off this morning. A wide variety of conditions will persist this morning, though with IFR or MVFR and mountain obscuration for a majority of the area. Conditions will briefly improve in the afternoon with VFR expected to develop for nearly the entire area, perhaps a few patches of lingering lower ceilings near the higher terrain. Conditions will deteriorate in valleys this evening into early Monday morning with LIFR/IFR low clouds and fog developing. -DW

MARINE. Updated 200 AM PST Sunday, 8 December 2019 . Weak high pressure will build into the waters today with improving conditions into Monday. Seas are likely to become steep Tuesday morning ahead of a cold front. The front on Tuesday will be the start of a new series of disturbances through the end of the week. This includes the potential for a high and steep long period west swell on Thursday that will accompany a stronger front. Peak swell is still indicated to occur on Thursday afternoon at around 17 feet at 18 seconds. Gradual improvement is likely to follow at the end of the week, though seas are forecast to remain high and steep. -DW

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
