Synopsis for the southern oregon coastal waters..Low pressure will move south of the area this morning and north winds will gradually increase with conditions becoming hazardous to small craft. Behind this low, warning level seas will develop late this morning as multiple swell trains move into the waters and north winds increase further. High pressure builds in Saturday and conditions improve some north of cape blanco. South of cape blanco, continued north winds will maintain very steep and hazardous seas. Winds increase, possibly to gales, Sunday as a strong cold front moves through the waters. A high and steep northwest swell is expected to follow Sunday afternoon into Monday.

Area Forecast Discussion National Weather Service Medford OR 327 AM PST Fri Jan 22 2021

DISCUSSION. A low pressure center is moving south about 100 NM offshore, currently off the Del Norte County coast, and the associated front is positioned over the coast. The low will continue south, so the front will not progress any further inland because the upper level support is diminishing. The rain produced by this front was mostly orographic driven. Red Mound RAWS has reported 0.41" and there are scattered reports of a few hundreths along the Coast Range north to about Humbug Mountain. Most of the rain falling over the valleys of Jackson and Josephine County is encountering a fairly deep dry layer almost 10 kft deep and turning to virga. This will saturate throughout this morning, allowing for the possibility of some sprinkles reaching the surface later in the day, though the chance of rain is quite low.

Cold air aloft will remain over the area Friday, creating an environment conducive for convection. Shower activity will peak in the afternoon, mostly over higher terrain, and diminish Friday evening as an upper ridge moves into the area from the west. Amounts will continue to be light. Snow levels will rise from 3000 feet overnight to between 3500 and 4000 feet by the afternoon.

A ridge will swiftly build over the region on Saturday, keeping the region dry, then just as hastily progress east. The ridging could allow for stratus and fog/freezing fog in west side valleys and the Klamath Basin, including along the Sprague River.

The remainder of the discussion is from the Thursday evening AFD . A short wave will ride over the ridge and this system will support the next front, which will move onshore Sunday. This front will be significantly stronger than the current system. This will bring the best chance for valley snows so far this year. Snow levels will largely be around 2000 feet early, so the low passes may see some impacts, including Hayes Hill, Siskiyou and Sexton Summits. The dry air in place may allow evaporative cooling in the lower layers of the atmosphere, which may bring snow levels down to the west side valley floors. That first shot won't last long, and the precipitation will change to rain. After the front moves through, it will change back to snow in post-frontal showers that will linger into Monday morning. Right now, there is a 60% chance for this scenario, while there is a 40% chance of snow occurring during the entire event everywhere except for the coast. However, even in the latter scenario, accumulations will not occur during the day, although some may occur at night. Overall amounts are not expected to be high, even in the mountains, but valley snow is always impactful.

Passing short waves will support shower activity into Monday night, then showers will diminish as an upper level ridge moves through. The break will be short though.

Long term discussion from the Thursday afternoon AFD . Tue 26 Jan through Thu 28 Jan 2021. As we head into Tuesday next week the system that moves in comes in unlike the systems that precede it through the weekend and very early next week. Previous systems ahead of this one were in northwest flow at 700 mb, while the one moving in on Tuesday sees the more usual southerly 700 mb flow. However, where the usual strong southerly flow brings warmer temperatures and higher snow levels, except for where the precipitation rates are very high like the Mt. Shasta region, cold air will be wrapped around the upper trough, bringing continued cold temperatures at ridge levels and higher.

As the front moves in Tuesday afternoon 850 mb temperatures are in the -3 to -5C range, which is very unusually cold for this type of strong southerly flow system. This will continue lower snow levels with this system, but with the stronger southerly flow orographic effects will be more dominant, with the bulk of the precipitation in Northern California, especially in the Salmon and Scott Mountains and the Mt Shasta Region, which could see possible amounts of near a foot or more. Heavy precipitation rates are possible on the Slater fire and the Red Salmon Complex Tuesday, but debris flow problems are not expected as the bulk of the precipitation will be as snow with snow levels of 1500 to 2000 ft during this time.

Previous EC runs showed very little precipitation, but the latest run came very much in line with with the GFS and confidence has increased to Moderate, say 40-50%, in these areas and out of our forecast area in the northern Sierras for this system. An active pattern with snow levels occasionally a bit higher will persist into the end of next week. Sven

AVIATION. For the 22/06Z TAFs . VFR will prevail for most areas late this evening and it will remain that way overnight over the east side. However, low pressure offshore will move southward. Rain is occurring along the coast currently (especially from around Bandon southward) along with MVFR and local IFR ceilings. This precipitation will spread inland by Friday morning, but it will be mostly on the light side. Expect MVFR ceilings and areas of higher terrain obscured over to around the Cascades Friday. Some lower ceilings and isolated showers could also reach Klamath Falls in the afternoon. Ceilings could be slow to break in North Bend, Medford and Roseburg, but VFR is expected to return mid-late afternoon. Showers by then should be focused in the mountains and areas south and east. -Spilde

MARINE. Updated 200 AM PST Friday, 22 Jan 2021 . Low pressure will continue to move south of the area this morning. North winds will gradually increase and conditions will become hazardous to small craft this morning. Behind this low, warning level seas will develop late this morning due to mixed swell and steep wind waves as multiple swell trains move into the waters and north winds increase further today. High pressure builds in Saturday and conditions improve some north of Cape Blanco. South of Cape Blanco, continued north winds will maintain very steep and hazardous seas. Winds increase, possibly to gales, Sunday as a strong cold front moves through the waters. A high and steep northwest swell is expected to follow Sunday afternoon into Monday. /BR-y
