| Area Forecast Discussion ...UPDATED National Weather Service Portland OR 1051am PST Wednesday Feb 11 2026 Updated aviation discussion. Synopsis High pressure maintains dry weather through Thursday with nightly chances for fog and frost in interior valleys and gusty east winds through the Columbia River Gorge. There is moderate to high confidence in a return to cooler and wetter weather Thursday night into early next week. .SHORT TERM...Now through Thursday...An upper-level ridge continues to slide eastward overhead, maintaining largely dry and benign weather across the region. Latest satellite imagery highligheights clouds over portions of Lane and Linn Counties on the northern fringes of an upper low meandering over California. These clouds along with continued low (10-25%) chances for light snow showers in the central Oregon Cascades will decrease through today as the aforementioned upper low weakens. Given widespread clear skies, a chilly morning with frost and patchy fog is expected across the region as temperatures fall well into the 30s. Thermal troughing along the coast will also support offshore flow, turning northerly to northeasterly through the Willamette Valley and along the coast. A pressure gradient of -3 to -4 mb between Portland and The Dalles favors gusts reaching around 25-30 mph at the western edge of the Columbia Gorge including the far eastern Portland/Vancouver metro, with higher gusts in terrain to the north and south through tonight. A weak upper-level shortwave passing overhead on Thursday will increase cloud cover, but is not expected to bring any precipitation. -36 Long Term Thursday Night through Tuesday...Upper-level ridging will continue to slide eastward away from the region while upper-level troughing shifts overhead from the Gulf of Alaska late in the week and persists into early next week. An initial frontal system will return rain to the region beginning late Thursday night at the coast and spreading inland through Friday. Ensemble guidance has come into better agreement that by the end of the weekend, the upper trough will pinch off into a closed low to the south while the Pacific Northwest instead remains in the col or saddle of the 500-hPa height field. This pattern would place the best synoptic support for ascent to the south of the region, while disorganized hit-or-miss showers are more likely locally. As such, post-frontal precipitation chances will persist through the weekend, but will trend lower as the cut-off low develops. Weaker support for ascent and the scattered nature of showery precipitation both contribute to a lowering of potential precipitation totals through the period. Snow levels falling to 3000-4000 ft within the upper trough will allow for accumulating snow at the Cascade passes, with 25-45% chances of six inches or more falling from Friday through Sunday afternoons, and 10% or less chances for one foot of snow. Valley locales will also see cooler temperatures within the upper trough, as morning lows fall to near or below freezing each of Sunday, Monday, and Tuesday mornings. Particularly on Monday and Tuesday, there is a 10-25% chance that snow levels will fall to 1000 ft or lower, which could see snow fall across the Coast Range, Cascade foothills, and possibly even to the valley floor in the early morning hours. Chances for even 0.1 inches of snowfall along the I-5 corridor remain only some 2-3%, and any snow that does accumulate would quickly melt as marginal morning temperatures warm above freezing each day, thereby limiting potential impacts. -36 Marine Thermal troughing along the coast will maintain breezy north winds over the waters into today, with gusts as high as 25-30 kt across the outer waters, particularly to the south of Cape Falcon. Small Craft Advisories remain in effect until 10 AM PST beyond 10 NM from Cape Foulweather to Cape Falcon, and until 7pm PST beyond 10 NM from Cape Falcon to Florence. Nearer to the shore, a slight offshore component to the wind (north-northeast flow) will minimize the risk of gusts hazardous to small craft, however locally higher winds can be expected downwind of gaps in the coastal terrain. As winds ease to 10 kt or less through tonight, seas continue at 5-8 ft through Thursday. Ahead of an approaching frontal system, winds will shift out of the south Thursday night into Friday, but are not expected to increase above 15 kt. Seas, however, will rise dramatically late in the week as a westerly long-period swell arrives, yielding increasing chances for seas to reach 14-16 ft by early Friday morning, however there remain low (less than 20%) chances for seas reaching into the upper teens. Seas look to ease to 7-10 ft by Saturday, continuing at those levels into early next week. -36 .BEACH HAZARDS...A high threat for sneaker waves is likely Friday through Sunday evening due to a long period westerly swell. Waves can run up significantly farther on a beach than normal, including over rocks and jetties. Sneaker waves can suddenly knock people off of their feet and quickly pull them into the frigid ocean which may lead to serious injury or drowning. Caution should be used when in or near the water, especially those who will be razor clamming. Keep children and pets away from the surf zone. Keep off of jetties, rocks and logs near the surf zone. If you see someone swept into the sea do not swim in after them. Call 911 and keep an eye on them until help arrives. -10 NOAA Portland OR Office: Watches - Warnings - Advisories OR...None. WA...None. PZ...Small Craft Advisory until 7pm PST this evening for PZZ272-273. |
