(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kpdt 210253 afdpdt area forecast discussion national weather service pendleton or 753 pm pdt Sun aug 20 2017 Short term Tonight and Monday... A weak shortwave passing by is pushing some mid and high level clouds across the forecast area. These clouds will exit to the southeast overnight leaving clear skies in place for the eclipse on Monday. An upper level ridge of high pressure off the coast will push inland on Monday helping to boost temperatures by 5 to 10 degrees Monday. Only made some minor changes to the evening forecast update. Prev discussion issued 305 pm pdt Sun aug 20 2017 short term... Tonight through Wednesday afternoon... A weak mid upper level shortwave continues moving across the region this afternoon with attendant high clouds. This system will move east and exit the forecast area this evening resulting in clearing skies by late this evening. A mid upper level ridge of high pressure upstream near 135w will move inland this evening. The ridge moves over the forecast area on Monday for clear skies for the eclipse. The ecmwf, canadian and GFS models all show a mid upper level low just offshore of the southern california coast Monday, which captures mid level monsoon moisture and wraps it around to the northern and northeastern flanks of the low Monday night. The low then transports the monsoon moisture northward Tuesday morning into northern california and the great basin. By Tuesday morning, the ridge over the pacific northwest moves to the rockies thus yielding a flow aloft that backs to the southwest during the day on Tuesday. This sets the stage for the monsoon moisture to enter southern oregon late Tuesday afternoon. Elevated instability associated with the moisture will bring a slight chance of late afternoon and evening thunderstorms to central oregon. The monsoon moisture then moves northeast across the blue mountains Tuesday night and Wednesday for a slight chance of nocturnal thunderstorms in ne oregon with a chance of showers and a slight chance of thunderstorms continuing through Wednesday afternoon. At this point conditions do not appear to support any threat of severe thunderstorms on Tuesday and Wednesday. Polan long term... Wednesday night through Sunday... Wednesday evening there will be an upper level ridge in mt, a cutoff low off central ca coast, and a strong low in the gulf of alaska. These systems will |
combine to form a southwest flow over wa and or with instability and moisture advecting into eastern or, triggering showers and isolated thunderstorms from central to northeast or. A thermal trough will enhance pressure gradients across the cascades and breezy conditions in the eastern columbia river gorge. As the low in alaska shifts southeast to vancouver island by Thursday morning then east across southern canada Thursday the associated cold front will push the moisture and instability in or east and dry west to northwest flow will move into eastern wa and or with clearing skies. There could be a lingering showers or thunderstorms over wallowa county Thursday afternoon. Strong cold air advection, tightening pressure gradients and increasing winds aloft will develop behind the front. The downslope winds will dry out the lower atmosphere with patchy blowing dust developing in the columbia basin. The winds and low relative humidity will cause fire weather concerns. Temperatures will be much cooler Thursday afternoon... With highs only reaching the upper 70s to mid-80s... Except 70s mountains. Radiational cooling from clear skies and light winds will keep Friday and Saturday night cool. An upper level ridge will move across wa and or Friday through Sunday. The dry northwest flow ahead of the ridge will keep eastern wa and or dry with a warming trend through the weekend. Coonfield aviation... 0z tafs...VFR conditions are forecast to prevail at all taf sites over the next 24 hours. Sct to bkn high level clouds are expected to continue through the early evening hours.

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. |
