NWS Forecaster Discussion
682 fxus66 kpdt 232101 afdpdt Area forecast discussion National Weather Service Pendleton or 200 PM PDT Wednesday Jul 23 2008 Short term...tonight through Saturday...a ridge of high pressure will build along the coast tonight...and then the ridge axis will move east of the Cascades Thursday. Thursday night a southwest flow with weak disturbances is expected...as the ridge continues to shift eastward...but with a dry stable airmass mostly sunny skies should prevail. By Friday evening an upper level low pressure system will approach the coast and a surface front may bring marine air through the Columbia River gorge as far east as The Dalles. Further east Friday will be the warmest day of the short term. There may be enough instability Friday for cumulus buildups over the higher terrain...but precipitation is not expected. The cool front will cross most of eastern Oregon and Washington Friday night...creating a cooler and more stable air mass across the area Saturday. 80 Long term...Saturday night through Wednesday...no significant issues to work out through the extended. Medium range models are in above average agreement regarding the large scale pattern showing typical summertime high pressure across the southern and central tiers of the Continental U.S. With quasi-stationary troughing across the northeastern Pacific. This would place the region under a fairly dry southwest flow aloft. Differences remain in the details but do not see any major differences that would greatly affect the trends. Will see periods of breezy winds, particularly across the Cascades gaps and occasionally reaching east to the lower elevations such as the Columbia Basin. Temperatures will be around seasonal normals. /Jbonk && Aviation...VFR cigs/vsbys. Reduced visibility at kpdt is due to dust from local field plowing activity. Actual surface visibility remains p6sm. Only significant aviation concern is for winds through the Colombia gorge. Expect westerly sustained winds to generally be in the 20-25kt range, including kdls, with locally higher speeds expected. Also expect potential gusts in the 30-35kt range. Winds should back off around 07z tonight with much lesser westerlies lasting until around sunrise. Tomorrow, winds are expected to remain below 15kts along with some possible high clouds. /Jbonk && Preliminary point temps/pops...
