Synopsis for northern california waters..Periods of breezy west winds will impact the coastal waters through the weekend. In addition, seas will remain elevated as a series of larger mid- to long- period northwesterly swells fill in and continue into early next week. A larger long period swell is expected to build in by midweek.

AVIATION
02/00Z TAFs...The main concern will be low level wind shear at Roseburg and Medford late this evening and possibly lasting until the end of the TAF period. Winds at the coast, including North Bend will increase later this evening and tonight, so were not expecting low level wind shear. However winds 2000 feet above ground level could get close to 40-45 kts.
Ceilings have improved for all of the terminals as were catching a relative break in the action. However this won't last long with ceilings likely lowering later this evening as another strong front approaches the area. Both ceilings and visibilities will lower, especially in the presence of moderate to heavy precipitation.
Snow levels will hover around 4000 to 4500 feet, so rain looks to be the primary precipitation type for most terminals. Evidence suggest precipitation at Klamath Falls could start out as snow for a brief period of time, then transition over to rain as snow levels rise.
-Petrucelli
SYNOPSIS
A parade of systems will be moving through the Pacific Northwest this weekend into next week. This will lead to multiple days of precipitation with small breaks (if any) in between. Snow levels will start around 4000 feet today and rise to 6000 feet by Saturday night and 9000 by Tuesday.
KEY POINTS: *Moderate to heavy snow is expected again tonight between 4AM and 4PM Saturday.
*Moderate to heavy rain is expected to continue through the next several days.
*Gusty winds are expected along and east of the Cascades, and possibly at the coast Saturday and Sunday.
*Ponding of water and rapid rises of streams and creeks are possible, but river flooding is not expected.
*High Surf with 15 to 20 breaking waves are expected through Tuesday.
*There is a limited risk for sneaker waves through Tuesday.
SHORT TERM
Tonight 12/1 through Saturday night 12/2...This morning Roxy Ann had snow! Although snow levels were above 3,500 feet, this shows that the precipitation was heavy enough this morning to push down the cold air. The Medford airport received 0.25" this morning and Phoenix saw 0.50". A quick view of rainfall totals at the coast show that the 24-hour total through 1 PM has reached 0.50"-1.00", and Brookings, Agness, and North Bend are near or have surpassed the 1" mark.
Another round of heavy snow will be found between Saturday 4 AM to 4 PM Saturday. Through this timeframe, locations along the Cascades, including Crater Lake, have a 70-100% probability to see 1" per hour snowfall rates. Road surfaces are forecast near the Cascades and east to fall below freezing tonight. With the current snowfall and anticipated snowfall tonight, this will create an extra hazard for slick spots on the road as snow and ice will stick to the surfaces.
Currently, wind gusts near Summer Lake of 40-60 mph have been reported, helping support the current Wind Advisory. Please keep in mind that gusty winds are possible where the heavy snow is falling and could lead to blowing snow and reduced visibility. Another area of concern is higher elevations for west side Saturday night into Sunday. A wind advisory is possible with guidance supporting stronger gusts near 50 mph, and that will be analyzed further.
The heavy rainfall concern continues through the weekend.
Forecasted PWATs for a 3-hour time range between 4 PM-10 PM Saturday are forecast to near 0.75" for Brookings, and with a forecast nearing 1 inch over that 6 hour timeframe, heavy rain is favored in the area for the evening. This heavy rainfall will continue for the coast into the overnight hours with another burst late Sunday morning into the afternoon.
The heavy cloud cover tonight will keep temperatures similar to last night and slightly warmer than normal. Afternoon temperatures will also be near normal with highs ranging from the low 60s at the coast to 30s/low 40s east of the Cascades. -Hermansen
LONG TERM
Sunday 12/3 through Friday 12/8... The Longer term portion of the forecast will continue the parade of systems moving through the Pacific Northwest and northern California. Periods of moderate rain are expected through Sunday evening, especially along the Cascades, Douglas County, and the coast and Coastal Range. Snow levels will be particularly high, between 7500 and 8500 feet with this atmospheric river.
A relative break is expected on Monday with less than a 5% chance for precipitation expected for Modoc County. Higher precipitation chances will exist everywhere else, with the highest chances (near 90%) for the Coast and the southern Oregon Cascades. These rain chances will spread out through Tuesday and Wednesday as additional systems parade through the area. Snow levels will rise to around 9000 feet. As a result, we will have to wait to see the potential impacts that this rain on snow can cause.
Will the snow pack we've established so far be enough to soak up the rain like a sponge, or will the rain cause the snow to melt and run off causing flooding? The best guess is somewhere in the middle of those two extremes, although confidence is relatively low at this point. The other concern we'll be monitoring over the extended forecast will be the potential for river rises. Currently the Northwest River Forecast center indicates a 5% chance of the south fork of the Coquille River at Myrtle point reaching action stage by Monday and maybe a 25% chance of reaching action stage by Thursday.
Chances remain at less than 5% for flooding at any river location; but the rapid river rises will need to be considered for the smaller streams and creeks.
The National Blend of Model suggests that snow levels may fall back down to around 4500 to 5000 feet by Wednesday and Thursday with additional systems moving through the area. With westerly flow, this is possible, but snowfall impacts will likely be negligible east of the Cascades. We will need to continue monitoring the extended forecast for additional impacts. -Schaaf
AVIATION
01/18Z TAFs...A complicated set of TAFs are expected over the next 24 hours with a wide range of ceilings, visibilities, and precipitation in the forecast. Generally expecting a range of MVFR to IFR conditions, but expecting more of the MVFR conditions.
Terrain obscuration is expected in periods of moderate rain and snow. Snow levels will hover around 4000 to 4500 feet, so rain looks to be the primary precipitation type for most terminals, but Klamath Falls (KLMT) will have snow in the forecast. The TAFs will continue to be busy through this cycle with brief breaks in precipitation expected. Also of note is the breezy to gusty wind speeds expected for KLMT this afternoon. -Schaaf/Guerrero
MARINE
Updated 200 PM Friday December 1, 2023...We'll catch a relative break in the action the rest of the afternoon through this evening with respect to winds, then they will increase again tonight as a warm front approaches the waters. At the same time, west to northwest swells remain elevated between 10-12 feet.
Winds will diminish for a brief time Saturday, then a strong warm front will result in increasing southwest winds Saturday evening and likely lasting through Sunday afternoon. High end Small craft conditions are likely and there's some data supporting low end gales for a brief period of time between 5 and 30 nm from shore over the northern waters, Sunday morning, but for now we'll hold off on anything for now and have the next shift take another look at this.
Keep in mind that it's possible a short duration Gales could be issued by tomorrow morning. In the meantime, we extended the end time of the Small Craft Advisory until 4 AM PST Monday.
The active weather will continue through the early next week with additional front moving through the waters with moderate to occasionally strong south to southwest winds. At the very least Small Craft Conditions are likely to continue through Tuesday afternoon.
-Petrucelli
BEACH HAZARDS
Active weather continues through early next week. A series of fronts will move through the region during this time along with multiple moderate swell trains. An extended period of sustained wave action is expected. Breaking waves of 15 to 20 ft will coincide with higher than normal ocean levels, leading to an increased risk of beach erosion. Additionally, there is a minor risk of sneaker waves as these swell trains build into the waters. Confidence is low, however, considering wind wave interference is likely to limit, but not completely negate the sneaker threat. If venturing to area beaches during this time, use caution when visiting and remember to never turn your back on the ocean! /BR-y/Hermansen
