Synopsis for the southern oregon coastal waters..Active weather will continue through the weekend with periods of moderate to heavy rain. Isolated Thunderstorms are possible today across the waters from cape blanco northward. Winds will continue to diminish this morning, however, seas will remain elevated and transition to swell dominated. A steep, heavy, long period west swell moves into the waters this morning and lingers into Friday evening, resulting in dangerous bar crossing conditions and hazardous surf zones. Seas gradually lower Saturday into Monday, but will remain steep due to ongoing swell.

Area Forecast Discussion National Weather Service Medford OR 834 AM PST Thu Dec 12 2019
SHORT TERM. An active wet pattern will continue to affect the area through Friday. A front has moved inland overnight and another shortwave will move into the area today. The area remains under moist westerly flow and a strong upper level jet is over the region. Expect this pattern to remain in place through Friday. As a shortwave move into the area later today, followed by another shortwave and weak surface low moving into Southern Oregon and Northern California Friday morning and afternoon, expect additional rounds of precipitation to affect the area.
Isolated thunderstorms have been observed over the northern coastal waters and models show weak instability from Cape Blanco northward through this afternoon. So have updated the forecast to add a slight chance of thunderstorms to the northern half of the coastal waters and along the Coos and Douglas coasts.
Overnight, precipitation amounts of around 0.5 to 1.5 inches have occurred over Coos County and into the Southern Oregon Cascades with lighter amounts of around 0.25 to 0.75 across other areas. Additional precipitation is expected today through Friday with heaviest amounts along the south coast, Kalmiopsis mountains and the Southern Oregon Cascades.
Snow levels are around 5500 to 6000 feet elevation this morning over northern portions of the CWA near Diamond Lake, Crater Lake and Chemult. Wet snow is possible down to around 4500 to 5000 ft in heavier showers but expect little accumulation below 6000 feet through this afternoon. Across central and southern portions of the CWA, snow levels are higher this morning around 6000 to 6500 feet and will remain elevated through this afternoon. Snow levels are expected to lower this evening through Friday morning down to 4000 to 4500 feet across southwest Oregon with higher snow levels of 5000 to 6000 feet from the Siskiyous southward. With continued showers during this period, light to moderate snow accumulations are expected over the mountains and for areas east of the Cascades. Heaviest amounts will occur above 5000 feet in the South Central Oregon Cascades, mainly in the Diamond Lake and Crater Lake areas. A winter weather advisory is in effect for these areas (please see the WSWMFR for details).
Otherwise, expect continued light to moderate rain today into Friday. This will result in ponding of water on some roadways and some moderate rises on area rivers and streams. Winds will be gusty to breezy over the area today with strongest winds over the higher mountains and into the Summer Lake area. Winds have gusted to 45 mph at Summer Lake and expect continued gusty winds through late today. Winds have trended lower in the last couple hours at Summer Lake but expect winds to increase again this afternoon with additional gusts to 45 mph expected.
AVIATION. For the 12/12Z TAFs . A mix of IFR/MVFR ceilings with terrain obscurations and local areas of LIFR are expected to remain the predominant conditions through this evening for most locations. A frontal boundary will remain draped across the area, bringing periods of rain through this evening. MVFR conditions may become more widespread later this morning and afternoon, but confidence in timing and exactly where is low. /BR-y
MARINE. Updated 130 AM PST Thursday, 12 December 2019 . Active weather will continue through the weekend with periods of moderate to heavy rain. Winds will continue to diminish this morning, however, seas will remain elevated due to building steep long period west swell. Swell dominated seas of about 15-17 feet at 17 seconds will impact the coastal waters from Thursday morning into Friday evening, resulting in dangerous bar crossing conditions and hazardous surf zones. Seas gradually lower Saturday into Monday, but will remain steep due to ongoing swell. /BR-y
PREV DISCUSSION. /Issued 300 AM PST Thu Dec 12 2019/
DISCUSSION . 13/00Z NAM/GFS/EC in.
There is widespread light precipitation across the Medford CWA this morning. The 12/00Z MFR sounding recorded a freezing level of 7500 feet, indicating the snow level around that time was 6500 feet.
The northern hemispheric pattern shows a wave number of 4 to 5 around the globe, which usually is a progressive pattern. That will be the case here. A ridge over the intermountain states continues to break down with a broad upper trough offshore.
Brisk quasi-zonal upper level flow will persist into Saturday with the jet stream pretty much focused on the Medford CWA. This will support low amplitude quick-moving systems moving onshore in rapid succession.
It will be quite wet over the Medford CWA into Friday evening, especially in the Coast Range. Storm total precipitation amounts from now through Friday evening will be 0.5-2.0 inches along the coast and up to 4.0 inches in the Coast Range. The Cascades will see 1.5-3.0 inches. Most other inland areas will see 0.5-1.0 inches of precipitation. The dry spot will be Lake County east of Winter Rim, which will see 0.25-0.5 inches. Snow levels will remain high, generally above 6000 feet through Thursday.
Rivers will rise quite a bit, but given the antecedent low stage levels, they should remain well below flood stage. Some small stream flooding may occur though.
Winds will also be a factor, especially today. Gusty south to southwest winds will be strongest over the mountains, but gusts to around 40 mph are expected into the southern Shasta Valley Thursday afternoon and gusts to 45 mph will occur in the Summer Lake area through Thursday evening.
Thicknesses will fall Thursday night into Friday and snow levels will lower to 4000-5000 feet Friday morning over Oregon and 5000-5500 feet over northern California. With continued showers during this period, moderate snow is likely Thursday night into Friday in the Southern Oregon Cascades, mainly in the Diamond Lake and Crater Lake areas, and over the Siskiyous and Coast Range from south central Siskiyou county northwest into the Kalmiopsis. Snow levels will fall further to around 3000 feet Saturday morning, but precipitation will be waning by that time.
Long term discussion from the Wednesday afternoon AFD . Sat 14 Dec though Wed 18 Dec 2019. There's decent agreement among the operational and ensemble models that the pattern will remain fairly active during the forecast period. It's all going to come down to the timing and details of individual systems.
On Saturday, we'll be on the colder side of things as a weak upper trough will move in from the northwest in the afternoon. Snow levels are expected to range between 3000 and 3500 feet and much will depend on precip intensity. For the most part it should be on the light side during the day, but could pick up in intensity Saturday night with snow levels around 3000 feet. Even then snow accumulations are not expected to be a high concern for the higher passes along the Cascades, Siskiyou Summit and Diamond Lake area. Preliminary estimates show generally 1-3 inches from Saturday afternoon into Sunday morning, but details on this could change in the coming days.
The operational models show different solutions Sunday through Sunday night. The ECMWF shows overrunning precipitation from a warm front moving into the area while the GFS is drier with warm frontal precipitation arriving Monday morning. This is also in line with the respective ensembles. For now did not make much change to the pops during this time.
Ridging builds into the area Monday with dry conditions expected. Another upper trough could end up splitting as it moves into the shortwave ridging Tuesday. There's a timing difference with this one and we could end up staying dry, but confidence remains low. More systems will head in our direction Wednesday through Wednesday night. -Petrucelli
