NWS Forecaster Discussion
855 fxus66 kpqr 041531 afdpqr Area forecast discussion National Weather Service Portland or 830 am PDT Sat Jul 4 2009 Synopsis...a strong upper level ridge of high pressure will remain over the Pacific northwest through the Holiday weekend...with continued hot temperatures through Sunday. An upper level trough will approach the area Sunday night...ushering in a fairly strong marine push and a quick 15 to 20 degree cool down for most inland areas by Monday morning. && Short term...visible satellite imagery shows that low clouds have come up the Columbia River as far as Kelso this morning. Models consistent in slight offshore in the low level winds this morning becoming only northerly in the afternoon while the 850 mb temperatures rise to Thursday levels. So continued very warm today. It looks like we see a change to more onshore Sunday afternoon with the main surge coming late in the day and in the evening. So...slight cooling with relative humidity up some and the main cooling Monday with deepening marine layer. Models not impressive with instability late Sunday...will back thunderstorm threat back to the Cascade crest. Likens Long term...no changes. Previous discussion follows...an upper level trough of low pressure will establish itself over the forecast area the first part of next week and will persist through the week. This will bring cooler temperatures and a chance of showers. && Aviation...IFR stratus along the coast and in the coastal gaps this morning will burn back to the beach later in the morning. Clouds should even break up along the coastline this afternoon as the surface gradients turn northerly. IFR stratus will return to the coast tonight in weak onshore flow. Clear skies are expected elsewhere for the next 24 hours. Kpdx and approaches...no significant weather impacts expected. && Marine...seas running 5 to 6 feet. However...with short period wind waves sea conditions will remain a little choppy. No advisories expected through the weekend. Winds will shift to the south to southwest on sun as a trough swings inland and surface high pressure builds in from the southwest. && Pqr watches/warnings/advisories... or/WA...none. && $$ More weather information online at... http://weather.Gov/Portland This discussion is for northwest Oregon and southwest Washington from the Cascade crest to 60 nautical miles offshore.
