Area Forecast Discussion National Weather Service Pendleton OR 836 AM PDT Mon Mar 30 2020

SHORT TERM. Today and tonight . A cold front will sweep across the region this morning followed by increasingly windy westerly winds through this evening before gradually decreasing overnight. Wind advisories continue through this evening. Precipitation will mainly be focused along the crest of the Cascades and over the eastern mountains. Snow levels will begin to lower behind the frontal passage with accumulating snow through tonight and into Tuesday. Winter weather advisories continue until Tuesday evening. .

PREV DISCUSSION. /issued 254 AM PDT Mon Mar 30 2020/

SHORT TERM . Today through Wednesday night. Strong upper level trough and jet moving into the Pacific northwest. Radar and satellite showing cold front moving onshore early this morning. This front will cross the forecast area during the morning and early afternoon with rain likely. Surface gradients and winds aloft are strong and expect increasing winds. Southerly winds this morning ahead of the front becoming westerly by afternoon. Expect widespread 20-35 mph winds with some locations having 40-50 mph gusts. Winds will diminish later in the evening and advisories will be in effect through 7pm. Current snow levels are 4-5k feet however these will lower to 2-3k late this evening and overnight. Based on this precipitation will be mostly rain through early afternoon becoming rain and mountain snow by evening into the overnight period. For Tuesday and Wednesday an upper level trough will remain over the region. Skies will be mostly cloudy with occasional rain and mountain snow. Temperatures will be cooler with highs in the 40s to mid 50s. Breezy westerly winds 10-25 mph each day. Persistent west to northwest flow aloft with the cooler airmass tonight into Tuesday will result in snow accumulations for the mountains. Winter weather advisories remain in effect. 94

LONG TERM . Thursday through Monday . Models are in fairly good agreement for the long term with long wave troughing over the western US with a main upper low meandering over western Canada. Deterministic solutions and model ensembles trending towards a persistent, moist west to northwest flow through the Pacific Northwest with a series of shortwaves embedded in the flow passing over the region. Expect a chance of low elevation rain and mountain snow showers most days, especially over the weekend as a duo of stronger waves pass over the Inland NW. Have trended cooler temps from previous runs as models starting to keep lower heights over the region. Expect afternoon temps in the 40s and 50s.

AVIATION . 12Z TAFs . Mainly VFR conditions expected through the period. Another weather system will move into the region today and tonight and bring more widespread showers and increasing winds. Can't rule out potential for a few thunderstorms, as well as small hail. Conditions will become MVFR, to possibly IFR, at times under steadier/heavier showers due to lowered CIGs and/or VIS. Mountain obscuration likely. Winds will increase late morning 18-28g30-40kts and continue through evening, becoming around 10kts or less tonight.

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.
