Area Forecast Discussion National Weather Service Portland OR 225 PM PST Sun Jan 19 2020

SYNOPSIS. Rather pleasant day across region today. But, clouds return tonight, with spotty light rain arriving later tonight. Overall, mostly dry on Monday, but good deal of clouds. Stronger front arrives Monday night and Tuesday, with rain. Series of fronts through rest of the week will maintain clouds and rain, with snow in the Cascades.

SHORT TERM. Tonight through Wednesday . Rather balmy in areas across the region this afternoon, with afternoon temperatures in the lower to middle 50s, through areas along the coast and to south of Albany towards Eugene are in the upper 50s to around 60.

Mid and high level clouds will be increasing from the south this afternoon into this evening. But, will stay dry. Weakening system well offshore will push towards the coast later tonight, with spotty rain along western Washington coast and Willapa HIlls, extending back along the north Oregon coast and nearby Coast Range. Overall, will stay dry farther inland with patchy fog and variable clouds. Still think have a minor chance of rain for Mon am inland, mainly from Portland northward, as the remains of the front pushes more onshore. As Mon progresses, will keep decreasing chance of rain along the coast, and return to cloudy and dry conditions inland.

Next front pushes toward the region Mon night, with rain increasing across the region later Mon evening. Some potential that the front will slow a tad, affecting how quick rain spreads inland. This due to the parent low slows as it approaches the Pac NW Mon night, and lifts towards Vancouver Island early Tue. Regardless of that, does look that will be quite wet later Mon night into Tue am, as the front shifts inland. Will transition to showers Tue am. Will keep minor chance of thunderstorms along the coast and over the coastal waters for later Tue am through the afternoon. Front will also bring breezy southerly winds to the region later Mon night and Tue, with gusts 25 to 35 inland and 45 to 55 mph along the coast. Even breezy over the higher terrain.

Interestingly, models show another enhanced boundary shifting across the region later Tue afternoon and evening. Lift could be widespread enough to produce more steady state rain for a time, but will word the forecast as showers for that timeframe.

Snow levels will stay up around 6000 to 8000 feet through Mon, then slowly lower later Mon and Mon night. Snow levels generally 3000 to 4000 ft by Tue am, and hold there into Wed.

Another strong low pressure over the north Pac will lift into the Gulf of Alaska on Wed. As it does, it will lift a warm front up and across the region on Wed, with rain increasing across the region from south to north. Will boost PoPs at 70 to 90 pct. /Rockey

LONG TERM. Wednesday night through Sunday . Rather progressive pattern with fronts shifting across the region from time to time. This will maintain periods of rain and Cascades snow, though timing of when heavier bands occur still somewhat in question. Overall, a wet period, with snow levels staying between 5000 and 6000 feet. Temperatures stay near seasonal range for mid to late January, with inland highs in the upper 40s to near 50.

AVIATION. VFR across the area, except for localized IFR/MVFR around KSLE to KCVO and another area of MVFR in the Gorge from KCZK to K4s2 and the upper Hood River Valley. Would expect the lower conditions from KSLE to KCVO to erode through the afternoon. Do not expect much, if any, improvement through Mon in the Gorge east of KCZK and in the Upper Hood River Valley due to the persistent offshore or up-slope low-level flow. Increasing mid and high level clouds after 06Z Mon, with MVFR cigs and/or vis in -RA at the coast 12-14Z Mon as a weakening frontal band moves onto the coast. This frontal band falls apart as it moves inland. There will also be areas of IFR or lower conditions in the central and south interior valleys after 05Z Mon due to fog development.

KPDX AND APPROACHES . VFR at the terminal and vicinity through Mon morning. Increasing mid and high clouds after 06Z. Will likely see IFR or worse conditions develop in the Tualatin River Valley after 05Z Mon. Offshore flow continues through the Gorge with gusts 35-45 kt at the west end. Easterly gradient slowly weakens overnight. Weishaar

MARINE. Slowly diminishing wind speeds today with strengthening high pressure aloft. However, speeds will start to ramp up tonight as the next front approaches the waters. Models have trended slightly weaker with wind speeds associated with the front. Expect 25-30 kt gusts late tonight, primarily over the outer waters. A stronger system moves through the region Mon night, which will likely produce solid gale force wind. There looks to be a slight lull late Tue through Tue night, followed by another potential gale event Wed. Model differences become more apparent for the latter half of the week, but do show some agreement that overall wind speeds will be on the order of 20-25 kt.

At 21Z seas were generally 11-13 ft, which was pretty close to the 12Z ENP guidance. Seas will hover around 10 ft late this afternoon through tonight and then build to 12-15 ft by Mon afternoon. There is the potential for 20-foot combined seas late Tue through Tue evening. Weishaar

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
