Area Forecast Discussion . UPDATED National Weather Service Portland OR 844 PM PST Fri Mar 5 2021 Updated Aviation and Marine Sections

SYNOPSIS. The rather complex system that has been impacting the area the past day continues to slowly move inland tonight as the overall system weakens. Another front arrives Sunday and also looks to weaken as it comes onshore. Generally speaking, the coast will receive the bulk of precipitation while the Cascades receives far less. Low pressure slowly slides south while centered well offshore to bring some form of rain and snow for much of next week.

SHORT TERM. Tonight through Monday . As the trough axis of this system moves onshore this evening and continues to push across the CWA, expect showers to continue to diminish. Late tonight and into Saturday a shortwave upper level ridge becomes established which will likely usher in a period of reduced precipitation. The air mass looks to remain slightly unstable and could produce some small hail through Saturday. However, this period will be short lived as the next large system coming from the Gulf of Alaska swiftly moves in by Saturday night. The front associated with the incoming system brings elevated PoPs back into the forecast for Sunday. Through Sunday and into Monday the parent low is expected to become more loosely organized, which will result in any precipitation follow a similar pattern. While the general organization of the system will diminish, there will likely be some atmospheric instability Sunday afternoon but, at this time thunder concerns are minimal. Monday the large system in which the surface looks to be centered close to 135W and 55N will start to dive southeast towards northern California. As the system drops southeast and continues to spread out, expect precipitation chances to diminish slightly but not fully disappear.

The air mass through the weekend and into Monday will be cool, which will cause a drop in snow levels to around 2000 to 3000 feet. This will result in new snow accumulations of 2 to 6 inches across the Cascades over the weekend and into Monday. Also, temperatures over the next few days will stay a couple degrees below normal. /42

LONG TERM. Monday night through Friday . The large low mentioned previously, will continue to move southeast through Wednesday. As it does so, there will be opportunities for embedded short-waves to rotate around the base of the upper low and bring rain chances every day through Tuesday. The remainder of the week look to be rather dry albeit with temperatures remaining somewhat below normal. /42

AVIATION. 06Z TAFS: As of 0430Z a cold front was situated over western Washington and Oregon and moving very slowly east. Generally VFR conditions along the coast and interior lowlands, with localized MVFR cigs, mainly associated with post-frontal showers. Precipitation coverage should diminish overnight, with the Cascades the favored location. VFR to be the dominant category at all TAF sites through 06Z Sun. However, decreasing showers and wind will enhance the likelihood of MVFR cigs late tonignt through Sat morning. In fact, the 00Z HREF ensemble mean low cloud guidance suggests MVFR cigs along the Cascade foothills will back-build into the Willamette Valley and southwest Washington interior lowlands late tonight.

KPDX AND APPROACHES . VFR at the terminal as of 0430Z. Localized MVFR exists in the Tualatin River Valley. Do not expect much change in overall conditions through 10Z or so. Thereafter, there is an increased likelihood of MVFR cigs developing, especially between the east part of the north Willamette Valley to the Cascade foothills. The threat of MVFR cigs persists through about 18Z Sat, then VFR thereafter. Weishaar

MARINE. Minimal changes to current forecast. Wind speeds have diminished this evening in the wake of a cold frontal passage. As of 0430Z general wind speeds were under 20 kt. Most recent ASCAT pass confirms this trend. Wind speeds continue to decrease through the night, becoming 10 to 15 kt by Saturday morning. However, another frontal reaches 125W longitude Sat evening. Wind speeds begin to ramp up Sat afternoon, but more so Sat evening. The 00Z NAM and GFS suggest a short period of low-end gale force gusts over the outer waters between 00Z Sun and 08Z Sun. Will hold off on issuing a gale watch as confidence is moderate at best and the time duration for potential gale force gusts is short.

Seas have eased to 12 to 15 ft this evening. There remains a distinct 8 to 10 ft WNW longer-period swell and a shorter period south wave train. Seas to remain above 10 feet through Sat morning and may briefly dip below 10 ft Sat afternoon. Seas build again Sat night and Sun, possibly getting close to 20 ft over the outer waters late Sun or Sun evening. The GEFSWAVE probabilistic wave height guidance valid 00Z Mon shows around a 40-50 percent chance of seas reaching or exceeding 18 ft. Weishaar

PQR WATCHES/WARNINGS/ADVISORIES. OR . None. WA . None. PZ . Small Craft Advisory until 1 AM PST Sunday for coastal waters from Cape Shoalwater WA to Florence OR out 60 NM.

Small Craft Advisory until 1 PM PST Saturday for Columbia River Bar.
