Area Forecast Discussion National Weather Service Medford OR 332 PM PST Tue Jan 26 2021

SHORT TERM. The big upslope heavy snow event has begun in the Mount Shasta City area and will continue tonight into Wednesday. More snow is expected to continue, albeit lighter, the rest of Wednesday into Thursday. Our simple message remains the same in that area -- please don't travel during this time frame. Dangerous conditions are expected tonight with intense snowfall rates at times (1-3"/hour) from Weed/Mount Shasta City southward, very limited visibility and low wind chills. This also includes McCloud and some spillover into the Tennant area. Strong winds at times (45-65 mph), especially north of Mount Shasta City near Weed could also result in possible whiteout conditions at times. Wind chills down to around 10 degrees are possible. Snow load could become an issue as snow piles up with tree damage and power outages possible. Snow amounts north of those areas in the Shasta Valley will be much lighter due to downslope effects. We are also expecting wind/snow impacts across southern OR (Coast Ranges of Curry/Josephine County), but impacts there won't be as extreme as what's expected in Siskiyou County.

A strong frontal system is moving onshore currently. A very tight pressure gradient in advance of this front (-11.8 MFR-RDD at 23z) is causing strong very winds in the Shasta Valley near Weed with a gust to 62 mph in the last hour. These southeast winds are also channeling through the Rogue Valley where gusts to 40 mph have been common with some gusts up to 55 mph in and around Ashland. Winds have also been strong along the coast south of Cape Blanco with gusts to near 60 mph at Port Orford and Flynn Prairie RAWS earlier this afternoon. High wind headlines have been updated and are out at NPWMFR.

The winds have been a precipitation killer here in Medford (so far) this afternoon with significant downsloping sending dewpoints down into the mid 20s. Where downsloping has been less, steadier precipitation is moving into the narrower Illinois Valley area with latest web cams showing roads getting snow covered at Hayes Hill. Expect a period of moderate to heavy snow this evening in those areas, especially at elevations above 1500 feet and also at the passes north of Medford like Sexton, Stage Road, Smith Hill and Canyon Creek where snowfall rates may briefly reach 1 inch per hour as the front moves through. Snow amounts of 3 to 6 inches are expected. As the front moves in this evening, winds should ease a bit in the Rogue Valley. Snow levels near Medford/Grants Pass will be around 1500 feet and this could bring some accumulating snow to the higher spots on the edges of the valley. The snow levels could also dip down to 1000 feet at times (perhaps slightly lower if precip is heavy enough) with light (1" or less) accumulations. In the Cascades, expect periods of snow overnight into Wednesday with accumulations generally 6 to 12 inches. Over the east side and in Modoc County, we expect lighter snows, but we've expanded the winter weather advisories to include most of the area that is expected to get 2 inches or more of snow. The reason is that the gusty winds may also cause blowing snow resulting in reduced visibility and hazardous driving conditions. The updated winter headlines can be viewed at WSWMFR.

The strong upslope flow will ease somewhat Wednesday morning, but another disturbance will rotate around the closed low offshore and this will continue to bring periods of moderate snowfall Wednesday into Thursday to the same general areas, but especially in the Mount Shasta region. Snow levels are expected to rise slightly with this next round of precipitation, so winter headlines will likely need to be adjusted by future shifts. -Spilde

LONG TERM. Fri 29 Jan through Tue 02 Feb 2021.

The stormy pattern will persist through the extended forecast period.

The extended period will start in a fast progressive pattern. A long wave upper trough over the area Friday morning will move out quickly. The upstream ridge will then move right through, with the ridge axis breaking to the east of the area Friday evening.

Any lingering showers from the previous front will end Friday. However, the next front will move onshore Friday night. This front won't amount to much, with relatively light winds and precipitation. Snow levels will start off around 2000 feet Friday morning, rising to near 3000 feet as the Friday night front moves in.

However, the progression will then slow as the ridge amplifies over the intermountain states and the upstream trough deepens offshore between 130W and 140W.

This evolution will slow the progress of the next front, which will move onshore Saturday night. It will stall over the west side, bringing an extended period of precipitation to the west side, especially in the "wet crescent" extending from the Coast Range in the Kalmiopsis wilderness area southeast to western Siskiyou county. Snow levels will mostly be 3000 to 4500 feet during this interval.

The progression will pick up speed Monday, and the trough will eventually move onshore Tuesday, but it will weaken quite a bit in the process. The stalled front will weaken Monday night into Tuesday, and precipitation will become lighter at that time. Snow levels will drop down to around 2500 feet Tuesday morning.

A strong ridge will move in behind the trough, bringing in strong north flow aloft. At low levels, the air mass will dry out and a east flow event will commence. There may be low clouds and fog trapped in the valleys, but the rest of the areas will clear out with gusty winds over the ridges.

AVIATION. For the 26/18Z TAFs . Over the coastal waters and along the coast . Areas of MVFR cigs in low clouds and rain will become widespread by this afternoon with higher terrain obscured. The lower conditions will persist into Wednesday with partial clearing Wednesday afternoon. Winds will be strong until a front moves inland late Tuesday afternoon. LLWS will be a concern at KOTH.

Inland from the Cascades west . VFR conditions will prevail initially, except for patchy IFR cigs/vsbys over the west side valleys, which will clear to VFR by Tuesday afternoon. However, widespread MVFR/IFR conditions will develop this evening in low clouds, rain and snow. The lower conditions will persist into Wednesday with partial clearing Wednesday afternoon. Winds will be strong until a front moves through this evening. LLWS will be a concern at KRBG and KMFR.

East of the Cascades . VFR conditions will prevail initially, but areas of MVFR cigs/vsbys in snow and local IFR cigs/vsbys in snow will develop late this afternoon with higher terrain becoming obscured. The lower conditions will persist into Wednesday morning, clearing Wednesday afternoon. Winds will be strong until a front moves through tonight. LLWS will be a concern at KLMT.

MARINE. Updated 340 PM PST Tuesday 26 Jan 2021 . Storm force Winds will weaken after the front moves inland this evening, but very steep fresh swell will follow tonight into early Wednesday morning.

South winds increase again Wednesday after a warm front moves through, followed by a cold front Wednesday evening. Winds will be much weaker than today's system, and are only expected to reach advisory levels at 20 to 30 kt. But, very steep seas build again Wednesday into Wednesday evening, peaking to around 18 ft.

Weak low pressure will remain over the coastal waters Thursday into Friday, then additional fronts will move onshore Friday night and Saturday evening.
