Fxus66 kpqr 230358 afdpqr area forecast discussion national weather service portland or 857 pm pdt Fri mar 22 2019 updated aviation and marine Synopsis A cold front will continue to move northeast across the forecast area this afternoon bringing a period of rain followed by some showers tonight and Saturday. Dry conditions are expected Sunday, before another series of frontal systems brings more rain next week. Short term Rest of today through Monday... Radar imagery shows a narrow cold front moving across the region this afternoon, with the back edge of the front starting to move into southwest oregon. This front has generally brought up to 0.20 inches of rain to southern portions of the forecast area and is expected to bring up to an additional 0.10 inches to northern portions of the area. Snow levels are currently above 5000 feet this afternoon so not expecting to see accumulating snow at pass level today. Models continues to show the cold front moving northeast across the pacific northwest this evening ushering in a moist and unstable air mass as the base of the upper level trough approaches the northern california coast. This upper level trough will then move inland on Saturday. Guidance continues to show a decent cold pool accompanying the upper level trough, with modest mid level instability and weak surface based instability aided by a weak shortwave disturbance and daytime heating. Will continue to keep thunderstorms in the forecast for Saturday. Snow levels are expected to lower to around 3000 feet on Saturday, with another couple of inches of new snow possible in the cascades but don't think we will reach advisory criteria. Also, given the lowering snow levels can't rule out the chance that some of the stronger showers may produce some small hail shower chances will come to an end late Saturday as the upper level trough moves east of the cascades and upper level ridging approaches the region. Given a stabilizing air mass, residual surface moisture, and light winds suspect most areas in the interior will see some patchy fog develop Saturday night and linger into Sunday morning. Otherwise, expect a rather pleasant Sunday with sunshine returning for the afternoon and evening and temperatures climbing back into the 60s. Rain chances will start to increase late Sunday as another cold front approaches the region from the south. This front is expected to approach the coast by Monday morning and move inland through the day bringing another round of valley rain and a couple of inches of new snow for the high cascades. 64 Long term Monday night through Friday... Active weather next week, as a large upper-level trough sits off the coast of washington and oregon most of the week, sending shortwaves into the pacific northwest. Used the national blend of models primarily for precipitation chances through next week because deterministic guidance doesn't reflect the uncertainty in the timing of these shortwaves that is reflected in more of a probabilistic forecast produced by the nbm. Monday night we will have lingering post-frontal showers from the

first of these shortwaves. Deterministic models (gfs and ecmwf) show us drying out on Tuesday as we are between systems. The nbm, however, keeps a chance of a few showers suggesting a the possibility of weaker, unresolved shortwaves generating a few showers on Tuesday. Have left a chance of showers in the forecast on Tuesday. Wednesday, deterministic models show another shortwave moving in, and this is supported by an increase in chance for rain in the nbm. Therefore, have likely pops in the forecast for Wednesday. Thursday, the trough that has been sitting offshore all week finally starts to weaken and move onshore. This will keep showers over our area through Thursday. There is greater uncertainty on Friday, with some guidance showing the development of an upper- level ridge starting Friday into next weekend, which would dry us out, or the pattern turning to more zonal flow which could keep a chance for showers on Friday. For that reason, the nbm keeps a chance for showers on Friday. The nbm does show a trend toward lower pops, however, suggesting most of the ensemble members are leaning toward drier conditions Friday going into next weekend. -mccoy Aviation Showery precipitation will taper off throughout tonight for inland locations.VFR conditions prevail through the morning hours as a mixture of mid and high stratus clouds remain in the postfrontal airmass. Fog lower CIGS could be seen inland as winds are starting to diminish. This could create areas of MVFR which could develop into ifr conditions towards the late evening or early morning timeframe. Kpdx and approaches... Postfrontal showers still remain, but are moving quickly out of the area.VFR conditions will remain through most of the night. CIGS could bring MVFR conditions around 16z-18z.VFR conditions look to return by 20z-22z. 42 Marine a showery post-frontal air mass will remain over the waters through Saturday, with a slight chance of thunderstorms over the waters during this time. Winds will remain fairly quiet through the weekend. The next system looks to weaken as it enters our waters Sunday night into Monday. However, this could bring back small craft advisory winds. The weather looks to be active, but no significant storms are forecasted at this time. Seas have now built into the low teens, with a dominant period of around 16 seconds. Seas will be peak around 12 to 14 ft tonight. Seas likely to remain above 10 ft well into Saturday night, before subsiding early Sunday. Seas then remain below 10 ft for most of next week, although they may briefly build back up near 10 ft with the Monday system. Pyle 42 Pqr watches warnings advisories Or... None. Wa... None. Pz... Small craft advisory for hazardous seas until 11 am pdt Sunday for coastal waters from CAPE shoalwater wa to florence or out 60 nm. Small craft advisory for rough columbia river bar until 11 am pdt Sunday. Interact with us via social media:

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
