Area Forecast Discussion...UPDATED National Weather Service Portland OR 1000 AM PST Wed Dec 6 2023
Updated public forecast discussion...
SYNOPSIS
Moderate to heavy rainfall continues across the region through today as a stalled atmospheric river slowly moves east through the region. As a result, river and urban flooding concerns will continue through at least this 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. Dry weather expected to return early next week.
SHORT TERM
Wednesday through Friday...UPDATE: Current radar imagery and observations as of 10 AM PST show moderate to locally heavy rain across northwest Oregon and southwest Washington as a stationary front remains draped over the area. Hourly rain rates remain around 0.1-0.25 inches per hour, though occasionally higher rain rates up to 0.4 inch per hour could be observed over the Coast Range and Cascades due to orographic forcing. The highest rainfall amounts have been from Salem to the Portland/Vancouver Metro Area, where around 0.50-0.75 in of rain has fallen between 7-10 AM. Several rivers remain over 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 this evening as this atmospheric river event continues. Please read the hydrology section below for more details.
Model guidance suggests that by late this afternoon, another stronger upper level shortwave trough will begin pushing the front eastward at a faster pace. 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 into Thursday as colder air moves in aloft and creates a more unstable atmosphere. Snow levels will also begin falling to around 4000-4500 ft by Wednesday evening, though the showery nature along with warm roads and surfaces means only a few inches of snow will be likely to accumulate in the overnight hours.
Broad upper level troughing is still expected to shift over the region on Thursday, bringing another round of widespread precipitation and cooler temperatures aloft. Rain amounts will be much lower than previous days, though the convective nature of this system may bring brief periods of scattered moderate rain. Snow levels will continue to fall through the day to around 2500-3000 ft by late Thursday night as another frontal system moves through the area. Ensemble 850 mb temperatures drop to around -2 to -4 deg C which would support accumulating snow at Cascade passes. Accumulation may still be difficult to significant amounts due to warm roads and surfaces. However, elevations above 3500 ft still may see anywhere from 4-14 inches in 24-hours. -Alviz/HEC/DH
LONG TERM
Friday through Tuesday...Drier and colder weather expected on Friday as ensemble guidance continues to indicate a brief break between weather systems. The next frontal system is slated to bring another round of precipitation on Saturday into early Sunday. GEFS/EPS continue to indicate an 80-90% probability of a plume of moisture with increased IVT values likely to be associated with this front. However, uncertainty still remains with exactly where the main plume of moisture with this AR will fall as well as in the timing of heaviest rainfall, though confidence is pretty high that this will not be as impactful as previous ARs. Latest guidance has shifted the main plume of moisture north into central and northern Oregon with rainfall totals of 1-2.5 inches over the Coast Range and Casacdes and 0.5-1.25 inches for inland lowlands. 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 early next week bringing a couple of dry days to the region. However, there are indications that another frontal system could impact the region sometime mid to late week, though uncertainty is high in precipitation amounts at this time. -HEC
HYDROLOGY
A surface front and associated atmospheric river remains over the region, moving extremely slowly southeast.
Widespread rain, locally heavy at times over the Coast Range and Cascades, will continue into this morning before the front begins pushing east quicker later this afternoon. Additional rounds of quicker moving light to moderate showers are expected tonight through Thursday.
Expected rainfall from 4 AM to 4 PM Wednesday ...
** S WA Coast/Willapa Hills 0.25 to 0.5 inches ** OR Coast /Coast Range 0.25 to 1 inches ** Inland I-5 Corridor 0.25 to 1.25 inches (includes Cowlitz, lower Columbia, Willamette Valley)
** South Washington Cascades/foothills 0.5 to 1 inches ** Western Columbia Gorge 0.5 to 1 inches ** North Oregon Cascades/foothills 0.5 to 1.5 inches ** Lane County Cascades/foothills 0.5 to 1 inches ** Mid-Columbia Gorge/Hood River Valley 0.15 to 0.75 inch
Flooding continues along many of the rivers and streams that drain from the Coast Range and Willapa Hills. Numerous flood warnings remain in effect with minor to moderate flooding occurring or expected. Landslides 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 today.
On top of that, many of the smaller streams and creeks will remain full into today, 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 Urban and Small Stream Flood Advisory remains in effect through this evening. -Rockey/HEC
AVIATION
Moist, southwest flow associated with an atmospheric river continues across the area through Wednesday. Predominately MVFR conditions along the coast and inland, with occasional heavy rain lowering conditions to IFR. MVFR cig probabilities remain above 50% for northern and central Willamette Valley and increase above 50% for the southern Willamette Valley after 14Z Wednesday as the front pushes farther southeast. All sites have a 30-50% of MVFR cigs persisting throughout the TAF period, as rain and mountain obscurations are expected.
*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 through Wednesday morning, while CIGS have begun to lower from around 4000-6000 ft to 1500-2500 ft Wednesday morning. As rain eases Wednesday afternoon, expect conditions to become a mix of MVFR and low VFR around 20-22Z Wed. South to southeast light winds Wed morning, increasing to 9-12 kts around 08z Thursday. /JH
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 of 16-18ft begin to gradually subside, expecting to be 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.
