SYNOPSIS
Another atmospheric river will bring widespread heavy rain to the region Saturday night through much of Sunday, resulting in river flooding and some urban flooding. Yet another atmospheric river is expected to impact portions of the area Monday night through at least Tuesday night, bringing a continued threat of river flooding and urban flooding. Snow levels should rise above 7000 ft Saturday night and remain high through Wednesday.

SHORT TERM
Saturday afternoon through Sunday night...Webcam, radar, and surface weather observations from 2:30 PM PST Saturday show persistent heavy snow has generally ended over the south Washington Cascades, north Oregon Cascades, and Lane County Cascades.
Occasional post-frontal snow showers will still occur through Saturday evening above 4000 ft, however additional accumulations should stay under an inch or so at pass level. Snow levels are still expected to rise above 7000 feet Saturday night. Therefore, the Winter Storm Warning that was in effect for the Cascades has been cancelled.

For locations west of the Cascades, conditions were cloudy with a light breeze, temperatures in the upper 40s to mid 50s, and a few post-frontal showers. Small hail and brief heavy rain has been reported with the strongest showers, but no lightning. However, weather conditions will become more active again Saturday evening/night into Sunday as the next atmospheric river (AR) takes aim mainly at northwest Oregon. The GEFS/EPS IVT plume forecast shows excellent agreement regarding the strength of this AR as both suggest IVT values will peak just under 750 kg/ms, which is in the moderate category. However, the latest suite of model guidance has shown a southern shift with this axis of heaviest rainfall, with the heaviest rainfall now expected to occur south of a line extending from Tillamook to Wilsonville. Locations north of that line, including southwest WA and the Portland/Vancouver metro, will still see heavy rain Sunday morning along with a threat of urban/river flooding, however it likely will not last as long as locations further to the south.

Precipitation should become light and showery across all of northwest OR and southwest WA by Sunday evening as the atmospheric river weakens and shifts southward into southwest Oregon. However, river levels will remain elevated through the night. Forecast rain amounts and expected impacts are discussed below in the hydrology discussion.

LONG TERM
Monday through Friday...The rain will continue to come as yet another AR arrives Monday evening. However, prior to that arrival, enjoy a drier early Monday as a very weak transient ridge sets up over the area. It will be very short lived, but, a much needed break between the two ARs. This system is shaping up to be the strongest of the recent storms as it is tapping into warmer air from the Pacific. At 850 mb, incoming warm air is around 8-9 deg C which will hold considerably more moisture than the cooler previous systems. NAM12 model runs show precipitable water content around 2 inches over the northeastern Pacific on Monday which, when it moves inland over cooler air and with orographic effects, will easily precipitate out. Between these warm temperatures and moderate the heavy rain, this AR has the potential to be strong.

In recent model runs though, this AR is shifting a bit further to the north, and really encompassing the Coast Range, Cascades and areas north of Marion County. However, this is just where the heaviest rain will likely be. Because of this spread accumulations will vary quite a bit spatially. In the areas with the heaviest rain (northern Coast Range and in the Gifford Pinchot Natl Forest), values range from 2.5-6.5 inches which is the 10th-90th percentiles respectively. Lower elevations will see less rain due to a lack of orographic lift, but will still be wet. North of Salem, the 10th percentile is around 0.5-0.75 inches and the 90th percentile around 2.5-3.5 inches. South of Salem the 90th percentile is around 1.5 inches. With these rainfall totals and the warmer air there will be significant snow melt. Therefore, another round of river rises is likely. Please see the hydrology discussion for more information.

In the post AR environment, we will continue to be showery with some cloud breaks. On Thursday a cold front will begin to drop down from the Gulf of Alaska. While initially this pattern appeared to be more of an AR type scenario, as the days have passed, it is not necessarily taking the same shape and rather that of an elongated robust trough. The cold air coming in could bring another round of snow for the Cascades and moderate/heavy rain for the region.

HYDROLOGY
A series of atmospheric rivers will bring periods of widespread heavy rain through early next week. Rain will become heavy again Saturday night into Sunday morning while snow levels rapidly rise above 7000 ft. Additional rain amounts expected Saturday afternoon through Sunday night: 0.75 to 2.0 inches along the south Washington and north Oregon coast, 2.0 to 4.5 inches along the central Oregon coast, 1.0 to 2.0 inches over the Willapa Hills, 1.5 to 4.0 inches over the north Oregon Coast Range, 3.5 to 7.0 inches over the central Oregon Coast Range, 1.0 to 2.5 inches across the interior lowlands of southwest Washington and northwest Oregon (highest in the Eugene-Springfield area), 4.0 to 8.0 inches across the Cascades and western Columbia River Gorge, and 1.0 to 2.5 inches over the central Columbia River Gorge and Upper Hood River Valley.
More rain is expected Monday through Wednesday with another atmospheric river, but uncertainty is high regarding exacting rain amounts with this system. That being said, this atmospheric river has the potential to be strong and warrants close monitoring. As of right now, the NBM is showing a 20-40% chance of 24-hour rain amounts in excess of two inches from Monday evening through Tuesday evening across the interior lowlands. The coast has a 50-70% chance, while the coastal mountains and Cascades have a 80-95% chance.

Given the forecast rainfall amounts expected this weekend into early next week, river levels will continue to rise. Most coastal rivers show a 40-60% chance of reaching minor flood stage and a 10-30% chance of reaching major flood stage in the next 10 days. This includes the Wilson River and Trask River near Tillamook, the Naselle River near Naselle, the Nehalem River near Foss, the Nestucca River near Beaver, the Grays River near Rosburg, and the Siletz River at Siletz.

Additionally, many other rivers across northwest OR and southwest WA still show anywhere from a 30-50% chance of reaching at least minor flood stage in the next 10 days, except for the mainstem Columbia and Willamette Rivers where the chance of reaching minor flood stage remains lower, around 5-10%.

Lastly, urban flooding is also possible this weekend, especially in low-lying areas with poor drainage. If you have gutters and/or storm drains that still need to be cleared out, now is the time.
Significant ponding of water and localized roadway flooding is expected on roads. Any motorists with travel plans this weekend should also allow extra time for their commute as hydroplaning will be a risk. Never drive through flooded roads. -TK/HEC

AVIATION
Rain and predominantly MVFR conditions spreading northward across the area this evening as a warm front lifts into the northern Willamette Valley ans stalls, with a few pockets of IFR possible after 09z. Will see southerly winds increase tonight as well, gusting 20-30 kt in the Willamette Valley after about 12Z Sun. Coastal areas may see gusts in the 30 to 40 kt range, with strongest wind south of KTMK. Winds gradually ease Sunday afternoon. Rain will taper to showers 21z-00z Mon as a trailing cold front sweeps across the area, with conditions improving to VFR across the north and high end MVFR as rain lingers south of KSLE.

KPDX AND APPROACHES...MVFR cigs likely to remain around FL015 overnight as rain continues into Sunday morning. Wind will gust out of the south to 20-25 kt at the terminal around 17z Sun into the afternoon. Rain tapers to showers 21-00z Mon with cigs improving back towards VFR around FL040. /CB

MARINE
Current observations at buoy 46050 as of 330am PST Saturday show southwesterly winds at 20-25 kt with gusts up to 40 kt as a frontal system moves through the waters. Seas are also building to 14-17 ft. Note that buoy 029 is currently out of service.
Expect winds to weaken to sub-Gales after mid-morning Saturday.
Following these Gales, winds will generally be westerly at 10-15 kt.
However, seas will remain elevated today so a Hazardous Seas Warning will be in effect from late morning Saturday through the evening.

Saturday night into Sunday morning, the next frontal system will approach the waters from the southwest. This will bring another round of southwesterly winds gusting up to 40 kt across the waters from Cape Falcon, OR southward. Therefore, another Gale Warning has been issued for these areas beginning Sunday night. Seas will remain between 10-14 ft.

A very active weather pattern persists Sunday through early next week, with a greater than 80% chance for additional rounds of Gale force gusts over the waters. Sub-Gale force winds are possible after Tuesday, however seas will remain elevated and build up to 18-20 ft at 16-17 seconds through mid-next week. This will also maintain the threat of sneaker waves along our coast. -Alviz
