Area Forecast Discussion National Weather Service Medford OR 946 PM PST Sat Jan 23 2021

UPDATE. The forecast has been updated for this evening through Monday morning. The primary adjustments made were to sky cover for this evening through Sunday morning, slowing the arrival of precipitation by about 3 hours over much of our inland area, and to adjust temperatures to be consistent with the most recent trends and guidance. Snow levels and amounts were also refined a bit.

DISCUSSION. Low level cloud cover trapped primarily between the Cascades, Siskiyous, and Coast Range this afternoon has lingered this evening keeping temperatures up a bit in the cloud affected areas. The forecast was updated to account for these clouds holding temperatures up some. Satellite trends indicate that this cloud cover in slowly thinning and dissipating as high level clouds generally increase. However, the high level clouds look as if they will be followed by a period of mostly clear skies overnight that should allow temperatures to fall to projected lows.

Overall, the inland progression of precipitation on Sunday looks a bit slower than previously anticipated, by about 3 hours. Snow levels are most likely to begin in the 1500 to 2500 foot range for areas inland from the coast. They then rise into the 2kft to 3kft range late Sunday morning into the early afternoon before falling again. Current headlines look good for snow accumulation to be an inch or more between 1500 and 2000 feet east of the Coast Range in the Josephine and Douglas counties, primarily in the Sexton/Canyon mountain Summit areas, and mostly around 2kft upward for other locations. As usual, precipitation rates, state of the ground, where the precipitation enhances most due to upslope flow behind the front, as well as how long showers continue Sunday evening, night, and into Monday morning will determine how much low elevations snow we get. The going headlines are on track. We will update our snowfall graphic and details in the Winter Weather Message text product shortly.

Keep in mind that we have another significant low pressure system expected Tuesday into Wednesday that is on track to bring heavy snowfall to much of Siskiyou and Josephine counties, as well as other portions of the forecast area. ~BTL

AVIATION. For the 24/00Z TAFs . Conditions are mainly VFR early this evening, though with areas of MVFR over the coastal waters north of Cape Blanco. Also, terrain obscuration in Coos County, eastern Douglas County, eastern Josephine County, and Jackson County. These conditions are expected to persist tonight. A cold front will reach the coast around 12Z Sunday morning with rain and a mix of IFR/MVFR. These conditions with a mix of rain and snow will spread inland, reaching the Cascades by 18Z then continuing across the east side during the afternoon. The freezing level will be around 2000 to 3000 ft. Conditions will transition to showers at the coast before 00Z Sunday afternoon with MVFR expected as rain and snow showers spread inland Sunday night. -DW

MARINE. Updated 800 PM PST Saturday, 23 Jan 2021 . A strong cold front will bring rapidly deteriorating conditions on Sunday. The marine hazards have been updated to begin the Hazardous Seas Warning earlier, at 10 AM Sunday morning. Also, this warning now extends across all of the waters, remaining in effect through Monday afternoon. A Small Craft Advisory remains in effect into Sunday morning (ahead of the front), while a Gale Watch remains in effect associated with the next strong cold front Tuesday morning through Tuesday evening.

The cold front, moving through on Sunday morning, will be accompanied by a long period west-northwest swell. This swell train will build from 3 ft at 22 seconds early Sunday morning to 6 ft at 19 seconds Sunday afternoon.

Behind the front, northwest winds increase to 20 to 30 kt across the waters with gusts to 35 kt possible in the outer waters. Rapidly building wind waves on Sunday will transition to a mix of wind wave and fresh swell. A dominant period of 12 seconds is expected while seas of 14 to 18 ft persist Sunday night through Monday.

Northwest winds diminish slightly late Sunday evening into Monday, and there will be a slight chance for thunderstorms late Sunday afternoon through Monday. Improvement in the sea state on Monday night will be very slight and brief. Winds increase Tuesday ahead of the next strong cold front. It is expected to move through the waters Tuesday afternoon through Tuesday evening with strong gales likely, and possibility of gusts reaching storm force. Another front is likely to follow on Wednesday with winds not quite so strong, likely at advisory strength. However, this will likely continue a trend of building steep to very steep seas into Wednesday night. A break between systems is likely Thursday with improving conditions into Friday morning. -DW

BEACH HAZARDS. Updated 800 PM PST Saturday, 23 Jan 2021 . A long period swell is moving into the waters tonight. As this swell builds, conditions will be favorable for a moderate to high threat of sneaker waves late tonight through Sunday afternoon. The sneaker wave threat is even higher considering this will arrive with an incoming high tide Sunday morning. The waves are not especially large, generally in the 3-6 foot range with periods of 19-21 seconds, but these waves could have the ability to run farther up the beach than usual, resulting in sneaker waves. See CFWMFR for details.

Even during calm conditions, sneaker waves can sweep up the beach without warning and knock unsuspecting people over and pull them out to sea. Shock and hypothermia can occur quickly in the cold Pacific waters. In addition, logs and other debris can be lifted and carried by the waves, crushing or entrapping unsuspecting victims underneath. Use extreme caution along the beaches and keep your distance from the ocean. NEVER turn your back on the ocean! /BR-y

PREV DISCUSSION. /Issued 304 PM PST Sat Jan 23 2021/

SHORT TERM . Tonight through Monday night . The forecast for tomorrow is a difficult one, but it remains on track. A frontal system will arrive tomorrow morning and could bring precipitation to southern Oregon, then northern California. The models continue to try and slow this front down, but overall the consensus is that precipitation will occur Sunday morning, with peak rates around 10 am to noon and then decreasing through the afternoon with showers in the evening into Monday morning. The snow levels remain on track around 2000 feet except for portions of Douglas County and the southern Rogue Valley where accumulating snow to 1500 feet is possible. The valley floors south of the Umpqua divide could see some light accumulation as well, but the best chances for snow are above the 1500-2000 foot levels. Portions of the Umpqua and Coquille valleys could see snowfall as well, but accumulations would be extremely modest if anything fell in those valleys (Camas mountain could see an inch or two). That being said, expect impacts to several highways, including Interstate 5 at Siskiyou Summit, Sexton, Stage Road, and Canyon Creek Passes. Please see the WSWMFR which highlights where snow impacts are expected in the short term.

Additionally, have kept the thunderstorm chances at the coast and along and west of the Coast range on Sunday night as the cold pool is the strongest at that time. Traditional thunderstorm metrics are a little less enthusiastic, but the cold pool could overcome the other stability metrics, warranting the slight chance we have. Snow showers will continue into Monday morning (except for the coast which may see rain showers). Any shower will be light in amounts, and things will dissipate in the afternoon and evening ahead of the next system coming in Tuesday. This is a much more potent system, and will be detailed in the Long Term discussion below. -Schaaf

LONG TERM . Long Term . Jan 26th through Jan 30th. 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, and continued lower snow levels.

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, rising in the afternoon. 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 and extreme southwest Oregon, especially in the Salmon and Scott Mountains and the Mt Shasta Region, which could see possible amounts of in excess of a foot in places, and one two 2 feet in places in the Mt. Shasta region. 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. With the heavy precipitation rates in Western Siskiyou county, and the the very narrow valleys in that area, the snow will cool the column of air and bring snow levels down lower than the rest of the region in valleys that are separated from the southerly winds. With this have lowered the watch down to 1500 feet in this area, although snow may come all the way down to the valley floors at times. Snow is trending towards lingering into Thursday in the Mt. Shasta region, and have extended the watch in this area. However, confidence is not high enough to extend the warning into the Wednesday night into Thursday time frame. -Sven
