SYNOPSIS
Moderate to heavy rainfall continues across the region through tomorrow as an atmospheric river stalls. As a result, river and urban flooding concerns will continue through at least Wednesday evening. A colder weather system will arrive Thursday, bringing additional rain and Cascade snow. There will be a brief break in the weather Friday before another warmer, yet weaker weather system arrives over the weekend.
SHORT TERM
TONIGHT THROUGH WEDNESDAY NIGHT...Current radar imagery and observations as of 2pm PST show widespread rain across northwest Oregon and southwest Washington as an atmospheric river pushes through the region. The cold front that moved in last night has slowed down, and is nearly stationary. Right now, the bulk of the rainfall is north of a line extending from western Lane County to Hood River.
Since last night, several rivers have reached at least minor flood stage and there have been numerous reports of urban flooding, including flooded roadways. Expect the threat for river and urban flooding to continue through at least Wednesday evening as this atmospheric river event continues. Please read the hydrology section below for more details.
The highest observed 1 hr rainfall rates so far have been between 0.25-0.40 in/hr. Here are general observed rainfall totals in the past 24 hours (2pm Mon to 2pm Tue PST):
- Coast: 2-4 inches - Coast Range, Willapa Hills, south WA Cascades and the northern-most portions of the north OR Cascades: 4-7 inches - I-5 corridor between Salem and Kelso/Longview: 0.50-1 inch - I-5 corridor between Salem and Eugene: 0.05-0.50 inch - Columbia River Gorge/Hood River Valley: 0.60-1.5 inch - Southern-most portions of the north OR Cascades and Lane County Cascades: 0.01-0.50 inch
The latest high-resolution models are in agreement of the front stalling, with moderate to heavy rain continuing across the region through at least Wednesday morning. The heaviest precipitation is still expected along the coast, Coast Range, south Washington Cascades, and northern-most portions of the north Oregon Cascades.
Forecast rainfall amounts over the next 24 hours are in the hydrology section. Winds in general will gradually weaken through tomorrow and be around around 5-10 mph.
Model guidance suggests that by late Wednesday afternoon, an upper level shortwave trough will begin pushing the front eastward. Once this happens, overall rainfall activity will decrease and briefly become more showery until the next system arrives Thursday. Post- frontal thunderstorms are a possibility along the coast Wednesday night as colder air moves in aloft and creates a more unstable atmosphere. -Alviz
LONG TERM
THURSDAY THROUGH MONDAY...Broad upper level troughing expected to shift over the region on Thursday bringing another round of precipitation and cooler temperatures aloft. A frontal system will likely move across the area on Thursday while snow levels fall from 4000 ft to around 2500-3000 ft by late Thu night. Ensemble 850 mb temperatures drop to around -2 to -4 deg C which would support accumulating snow at Cascade passes. Due to the previous days of warm air, warm soils and roads, accumulation may be difficult to significant amounts. However, still may see anywhere from 6-10 inches in 24-hours.
Drier weather expected on Friday as appears likely to have a brief break between weather system. The next frontal system then expected to bring another round of precipitation on Friday. A plume of moisture with increased IVT values likely to be associated with this front, though there remains considerable uncertainty with exactly where the Atmospheric River will take it's aim. Latest models show this to be more directed toward the southern Oregon coast. Snow levels are expected to rise again on Saturday from around 3000 ft to 6000 ft. WPC cluster analysis shows upper level ridging building over the Pacific coast on Sunday, likely trending toward another break between systems. -Muessle/DH
HYDROLOGY
Still have rather slow moving front over the region, with continued rain, some locally heavy over the Coast Range and Willapa Hills into early this evening. Still, not much rain to south and southeast of Albany. As rest of the afternoon and evening progresses, the rain will push farther east and south, with all areas back in the rain for a while. Rain will decrease later tonight. Even, so, will be enough rain to maintain high water levels in our streams and rivers.
Expected rainfall over next 24 hours (most will fall tonight)...
** S WA Coast/Willapa Hills 0.5 to 2 inches ** OR Coast /Coast Range 2 to 4 inches ** Inland I-5 Corridor 0.75 to 1.5 inches (includes Cowlitz, lower Columbia, Willamette Valley)
** South Washington Cascades/foothills 1 to 3 inches ** Western Columbia Gorge 1 to 1.5 inches ** North Oregon Cascades/foothills 1 to 2 inches ** Lane County Cascades/foothills 0.5 to 1.5 inches ** Mid-Columbia Gorge/Hood River Valley 0.5 to 1 inch
Flooding continues along many of the rivers and streams draining the Coast Mts and Willapa Hills. Numerous flood warning remain in effect, with minor to moderate flooding. Have had reports of slides as well, one affecting Amtrak line in northwest Clark County. Other slides may occur, so anyone near steep hillsides should remain alert for changes in conditions of soil and vegetation. Flood Watch remains up for most of southwest Washington and northwest Oregon through Wed. But, with not so much rain over to south and southeast of Salem, suspect may have to lower watch in that area, as rivers not expected to flood in Linn or eastern Lane County.
On top of that, many of the smaller streams and creeks remain full tonight into Wed, with some minor flooding expected. Areas with poor drainage, such as railroad crossings and underpasses, as well as areas with leaf-clogged drains, will see significant ponding of water. An Small Stream and Urban Flood Advisory remains in effect through Wed evening as well. /Rockey
AVIATION
Moist, southwest flow aloft as a slow moving frontal boundary associated with an atmospheric river continues across the area through Wednesday morning. Predominately MVFR conditions along the coast, while a mix of VFR and MVFR conditions persist inland due to variable VIS with the rain. MVFR CIGS probabilities increase above 50% after 06Z Wed across the central and northern Willamette Valley, and after 14Z Wed for KEUG as the front pushes farther south. Expect rain and mountain obscurations through much of the TAF period. Still breezy just above the higher terrain, with southwest winds 20 to 40 kt at 2000 ft and higher through 06Z Wed.
*Please note that the automated weather station at KONP (Newport) is currently out of service. This site is not maintained by the National Weather Service. Because of this, the TAF produced for KONP is based on model data without the input of observations, and may not be representative of current conditions.*
PDX AND APPROACHES...Rain will likely continue to maintain MVFR VIS this evening, while CIGS are expected to lower from around 4000-6000 ft to 1500-2500 ft overnight. As rain eases Wednesday afternoon, expect conditions to become a mix of MVFR and low VFR around 20-22Z Wed. South to southeast winds around 7-9 kt expected into Wed morning. /DH
MARINE
A dynamic pattern will maintain active weather across the waters through the weekend. Winds have eased and are expected to become northerly as weak high pressure moves over the area on Wednesday. The main impact across the coastal waters will be hazardous seas through Wednesday due to a strong, long period westerly swell. Seas Tues night are likely to peak around 17 to 20 ft before gradually subsiding to below 15 ft late Wed afternoon to early evening.
The next frontal system is expected to approach from the west later Wednesday and move across the coastal waters Wed night.
Small Craft Advisory conditions are likely to continue through Thursday. High pressure on Friday will bring a relatively brief break. Another strong frontal system on Saturday will bring increasing chances for Gales.
