Synopsis for the southern oregon coastal waters..Heavy and steep long period swell will remain high into Sunday, with winds diminishing this evening and overnight. Seas will continue to diminish tonight into Sunday, finally subsiding below advisory criteria late Sunday into Monday. This will be short-lived, however, as another swell train moves into the waters Tuesday ahead of the next frontal system. This front will bring increasing southerly winds Tuesday night and Wednesday, and with building seas, conditions will likely become hazardous to small craft.

Area Forecast Discussion National Weather Service Medford OR 733 PM PST Sat Dec 14 2019

UPDATE. Updated Marine and Aviation sections. The only changes to this evenings forecast was to add an additional small, broad amount of snow coverage along the Siskiyous and Cascades near Klamath falls. On radar, the most recent bands have been falling apart after moving over Coos County, but a few isolated showers are pushing further inland causing this change to be made.

The surface low that is responsible for this precipitation is visible on IR and the nighttime RBG satellite products. The low is just offshore of Florence and will continue to move onshore through the night with slight southerly movement. This will shift any linger showers south, mainly near the Oregon, California border.

Models are trending down cloud coverage for tomorrow afternoon and more places may be likely to get some much desired sunlight. With this, the high temps will likely need to be nudged up a few degrees. However, this break in cloud cover will be fairly brief, as another weak front will graze the coast Tomorrow night. More information on this and the active weather pattern following it can be found in this afternoons discussion below. -Miles

PREV DISCUSSION. /Issued 159 PM PST Sat Dec 14 2019/

DISCUSSION . The latest visible image clearly shows an upper through moving in from the northwest. Precipitation ahead of it is already reaching the coast with Brookings and Gold beach reporting rain. Precipitation will continue to push inland early this evening with most centered along the coast, coastal mountains and northwest California. A weak surface low will follow the front late this evening and tonight. The models are in good agreement tracking the low through southwest Oregon and northwest California.

Snow levels this afternoon are expected to be around 3000 feet, then lowering to around 2500 feet tonight, but road snow accumulations are not expected to be a concern because were not expecting a significant amount of precipitation. For example up to an inch is expected over Siskiyou Summit, Lake of the Woods and Diamond Lake area from late this afternoon into early Sunday morning.

Sunday, there's some hint as warm frontal precipitation over the northwest part of the forecast area in the afternoon through Sunday night. However at the same time 500 mb heights will be on the rise as upper ridging builds in. For now kept in a slight chance to chance pops of the above mentioned area.

Monday will be dry as shortwave ridging builds into the area. If there's enough clearing, we could be dealing with low clouds and patchy to areas of fog later in the evening through the morning hours Sunday night through Tuesday.

The upper ridge axis shifts east Monday night into Tuesday as an upper trough approaches from the west. Models vary on the evolution and details, but the general consensus is for the upper trough to split which will limit the amount of precipitation. Most of Tuesday will be dry, but could not rule out a chance of rain along the coast late in the afternoon. -Petrucelli

EXTENDED DISCUSSION . 12Z Wednesday through 12Z Sunday.

Heading into Wednesday, the models are starting to come into consensus with a low strengthening in the Pacific and with high pressure building off the southern California coastline. This will set the stage for a strong atmospheric river (AR) hitting southern Oregon from roughly Thursday into perhaps Saturday. Given how low the rivers will be before the AR arrives, this AR will be more of a beneficial AR for building snow pack and avoiding serious flooding. At this time, some points on the Coquille river are projected to hit action stage, yet avoid flood. However, we are still quite far out from this event, so flooding still remains possible, especially on the Coquille river. Many of the rivers will likely experience some rapid rises between the 20th and 21st. As for building on the snow pack, we're expecting snow levels around 5000 to 6000 feet for most of this event. This will result in some travel concerns over the Cascade passes, specifically around Diamond Lake, Crater Lake and elevations above 6000 feet.

Eventually, this low will probably become more progressive and start to deepen and shift eastwards, this would be a good thing. The AR would then probably take aim towards Canada and Washington with the heavy precipitation shifting northwards. The other scenario is we stay at the receiving end of this AR and still see some significant precipitation well into Saturday. It's still too uncertain to say at this point what exactly will happen Saturday and beyond.

Overall, the potential for minor flooding along the Coquille remains a concern along with travel above 5000 to 6000 feet from Thursday into Saturday.

-Smith

AVIATION . For the 15/00Z TAFs . Rain will start to valley at most terminals this evening. Look for patchy fog and perhaps some LIFR visibilities later tonight in valleys west of the Cascades. East of the Cascades, we'll see some snow reduce visibilities to IFR thresholds. Eventually skies should clear up near the end of the TAF period on Sunday afternoon.
