Thunderstorm chances develop Monday over the cascades but continue Tuesday and expand westward to the valley as well. Temperatures trend gradually cooler with rain chances during the second half of the week as a disturbance tracks across the pacific northwest. Short term Tonight through Tuesday... Not much in way of changes. Warm night inland, where afternoon temperatures reached upper 80s and low 90s. In contrast, coastal beaches stayed in the lower 60s, with some spots stuck in the middle to upper 50s thanks to persistent low clouds. Low clouds now working up the river valleys from the coast into the coastal mountains, with a few spots reporting drizzle this evening. Gradients suggest that areas of low clouds will filter into the south willamette valley late tonight into early Sun am. Also, low stratus will seep up the columbia river to kelso, but likely stalling their inland progress around kalama. Otherwise, not big changes in the forecasts and trends through mon. Water vapor satellite imagery reveals a shortwave ridge over the northeast pacific. The ridge axis will slowly shift inland through Monday, which will produce little change in the overall weather pattern except for gradually cooling temperatures and an increase in marine clouds pushing inland each morning. Steeper mid level lapse rates moving into the region will open the door to the possibility of some showers and thunderstorms developing near the cascade crest late Monday afternoon and evening. A slight southeasterly component to the steering flow could allow a few showers to drift towards the willamette valley Monday evening, but confidence in this scenario is low at this point. As we move forward in time, the next shortwave trough is forecasted to impact the region on Tuesday. Operational model guidance continues to waver on rain chances for Tuesday with the latest ec coming in quite dry. Given the basic pattern and a number of ensemble members |
continue to show a pattern favorable for at least some shower and thunderstorm development, will maintain chance to low end likely pops for Tuesday afternoon and evening. Neuman Long term Tuesday night through Saturday... A cooler onshore flow pattern looks to take hold during the second half of the week. Cooled temperatures closer to model consensus for much of this period as a result. Rain chances continue to vary wildly among different models so left a fairly generic rain forecast at this point. However, pops were increased most periods, particularly during the afternoon and evening hours when daytime heating may trigger at least some showers across the area, especially if the upper level trough lingers over the region. Neuman Aviation Onshore flow will push the shallow marine stratus into the western valleys of the coast tonight and persist through much of Sunday with ifr lifr conditions. Inland areas mainlyVFR but ifr to low MVFR CIGS expected to seep into part of the south willamette valley, and along the lower columbia river to near kspb by early Sun morning. Clouds inland will dissipate by midday. Kpdx and approaches...VFR through Sunday. Western approaches may see patchy ifr CIGS between 11z and 19z Sunday. Mh Marine Winds will continue below 20 kt through at least the middle of next week. Northerly winds continue over most of the waters through the weekend. However nearshore winds will switch back to out of the south again tonight, accompanied again by low stratus and fog. Seas have settled in the 6 to 7 foot range and will settle to around 5 ft through most of next week. Decided not to issue a small craft advisory for rough columbia river bar for Sunday's morning ebb given the relatively benign reports from the morning ebb today and similar conditions expected tomorrow.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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. |
