Area Forecast Discussion National Weather Service Portland OR 925 PM PST Fri Feb 26 2021

SYNOPSIS. Cool northwest flow aloft continues tonight, but showers will gradually decrease. Still, up to another foot of new snow could fall over the high Cascades tonight. Then, a break in the weather for Sat and Sun, with mostly dry weather for most areas. Next front will bring rain back across the region on Monday, with showery weather continuing well into next week. But, at least temperatures will moderate into the 50s next week, with a chance, yes a chance of near 60 deg inland valleys by Thu and Fri. Gardeners, stand by.

SHORT TERM. Tonight through Monday . Showers to continue overnight under a cool northwest flow aloft. Orographically enhanced showers continued over the Cascades Fri evening, but expected to only slowly decrease overnight. Will allow the winter storm warnings to run their course until expiration early Sat morning. Will go ahead and drop the high surf headlines for the coast a little early as seas have already dropped under 20 ft at 14 seconds, and expected to continue to subside overnight.

Remainder of short term discussion unchanged from 221 PM Friday discussion . Weather begins to become more quiet on Saturday, with decreasing showers from north to south. Will maintain snow showers over the Cascades, with another 1 to 6 inches of snow likely. But, elsewhere, generally dry with partly cloudy skies for the afternoon. High pressure will build across the region Sat night, and remains in place through Sun. This will maintain dry weather during that time, with some patchy fog or low clouds later Sat night. Otherwise, near seasonal temperatures for the last day of February.

Another front arrives in the region early Mon, with increasing clouds and spotty rain in the morning. But, transitions to showers by afternoon. Snow levels will start near 5000 ft Mon, but drop back to 3500 to 4000 feet in the afternoon.

After peaking at 25 to 30 ft this morning, seas are subsiding. As of 2 pm, seas still running 21 to 25 ft close to shore. Seas bit lower as move southward along the Oregon Coast, with 17 to 20 ft towards Florence. This will maintain rather chaotic surf zone this evening. Will extended the High Surf Advisory out through rest of this evening. Conditions will gradually improve overnight. /Rockey

LONG TERM. Monday night through Friday . Models continue to have a challenging time resolving what to expect through next week. Given the uncertainty, have chosen to use a blend of model solutions with the NBM as a foundation. Despite keeping some chance of showers for most of next week, does appear will have a slight warming trend. In fact, some models suggesting potential for highs getting close to 60 by Thu and Fri across the Willamette Valley. Ah, signs of spring, with return of robins, daffodils bursting, and near 60 degrees. Regional gardeners, prepare your shovels and rakes. /Rockey

AVIATION. Active weather this evening will slowly dissipate through the night. Radar is continuing to show showers move southeast across the area but these should become more sparse and cease by roughly 10Z Saturday. Potential for brief periods of MVFR ceilings with passing showers. Gusts around 20 kt will continue along the coast through the night but winds will weaken inland. Predominantly VFR conditions with light winds after 15Z as high pressure builds in behind the front.

KPDX AND APPROACHES . VFR with light showers expected through roughly 10Z. Potential for MVFR conditions with passing showers but these should be brief. Light winds with VFR ceilings expected through the end of the TAF period. -BPhillips

MARINE. Active seas remain with high energy waves and gusty winds. Seas are exceeding 20 ft throughout all of the waters with the highest seas north of Cascade Crest. Seeing 23-25 ft waves at 16 seconds in the northern waters, while the central waters are trending more at the 21-23 ft range. Likely will see the seas begin to ease over the next several hours but will take a bit of time to truly fall below 18 ft. Models have been rushing the dissipation of these conditions as buoys continue to show the elevated waves. Decided to extend the time frame of higher seas through early Saturday morning. A high surf advisory is in place along the central coast and a high surf warning issued for the northern Oregon and southern Washington coast through this evening. As previously stated, expecting a very slow decrease in energetic seas through the overnight hours into Saturday. By Saturday afternoon, expecting 13 to 15 ft seas at 14 seconds. Likely will see a bit more deterioration on Sunday as more intense high pressure takes over and the passing disturbances shift eastward.

Winds are another concern, but they are beginning their steady decrease already this afternoon. The northern outer waters are still under the Gale Force Warning while the central waters are lower and under a Small Craft Advisory. While gales are still present up north, should see them ease overnight;this will be one of the drivers for the seas lowering during this time. Could still see isolated gusts to 35 to 40 kt after midnight Saturday, but not expected to be widespread. By Saturday afternoon, winds will almost completely drop off to marginal small craft levels through Monday morning.

Monday afternoon, a front will pass over the waters which will bring another surge of increased winds, but doesn't look to impact seas where they will remain 12 to 14 ft with winds 15 to 20 kt with gusts to 25 kt. The next system arrives late Wednesday into Thursday. At this point, there is still quite a bit of uncertainty but it does appear to be the addition of a very energetic southerly fresh swell. Could see wave heights exceeding 20 ft but staying conservative due to a great amount of uncertainty. -Muessle
