  (on/off)  Help NOTE: mouseover dotted underlined text for definitionFxus66 kpdt 180305 afdpdt area forecast discussion national weather service pendleton or 705 pm pst Sun feb 17 2019 Short term Short wave moving through in the northerly flow aloft combined with a cold front resulting in scattered snow showers and cloudy skies. Expect this will continue overnight. Northerly flow continues Monday although the airmass is drying so partly to mostly cloudy skies. The next system to impact the region will be a low moving across the pacific northwest Tuesday into Wednesday. This will result in another round of accumulating snowfall. Model precipitation forecasts show a significant amount for the mountains. Temperatures will remain well below normal through the period. 94 Prev discussion issued 239 pm pst Sun feb 17 2019 short term... Tonight through Wednesday... A large trough remains over most of the CONUS this afternoon. An upper low is moving south over northern california and nevada and its influence over our area is steadily decreasing. Another low pressure area in southern alberta is sending a cold northerly flow into the area. Moisture is limited with the incoming arctic air but radar is showing some returns over the columbia basin and blue mountain foothills. Am expecting isolated light snow showers mainly over the washington cascades, blue mountain foothills and northeast oregon mountains but anywhere aside from the washington columbia basin and central oregon could see a stray shower. Snow amounts will be less than an inch. Snow showers will taper off tomorrow morning and the area will get a break Monday afternoon through Tuesday morning. The main story will be colder temperatures as lows tonight will be in the teens and in the mid single digits to mid teens Monday night. Tomorrow will have high temperatures mainly in the 20s though central oregon should reach the lower 30s. The next concern will be a system out of the gulf of alaska arriving Tuesday afternoon and impacting the area through Wednesday. The entire area will have snow with this system and winter weather highlights appear probable Tuesday night and Wednesday over the blue mountain foothills, grande ronde valley and wallowa county (2-5 inches) and eastern oregon mountains (4-9 |
inches). The rest of the area will get 1-3 inches. Future shifts will have to monitor to see when the confidence is there for any watches, advisories and warnings to be issued. With increased cloud cover, lows Tuesday night will be in the 20s and highs Wednesday will be in the mid 20s to mid 30s. Perry long term... Wednesday night through Sunday. Snow showers will linger over the area Wednesday night as the upper level system starts to move east. It will continue to be cold through the week, but should be drier Thursday into Friday as a ridge of high pressure moves through. Another low pressure system will be approaching the area Friday night with a chance of light snow across the area Saturday with a cold front Saturday night. The upper level trough remains over the area Sunday with another low dropping down the coast. This will turn the flow more zonal and keep some area just east of the cascades more shadowed from light snow but most area will continue to see some periods of light snow. Temperatures will remain below normal. 93 aviation... 00z tafs. Ifr lifr low clouds and fog will continue through the evening at pdt alw psc as band of low clouds continue to move south over the area and bank up against the blue mountains. Ykm will also see slight upslope flow with light snow and MVFR conditions overnight. Northerly flow will continue on Monday with some clouds banked along the foothills with MVFR at alw pdt and mainlyVFR at other locations. 93 Preliminary point temps pops Pdt 18 29 13 30 30 10 0 20 alw 19 28 15 30 30 10 0 20 psc 19 30 15 29 20 0 0 20 ykm 22 31 15 30 30 10 0 20 hri 21 31 16 31 20 10 0 20 eln 18 30 13 30 30 10 10 30 rdm 18 34 16 36 10 10 10 20 lgd 16 28 11 31 30 10 0 30 gcd 19 29 14 33 10 10 10 20 dls 26 37 24 37 20 10 10 30 Pdt watches warnings advisories Or...

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. |
