Area Forecast Discussion National Weather Service Pendleton OR 144 PM PST Thu Mar 4 2021

SHORT TERM. Tonight through Saturday night. Low pressure offshore with a cold front along the coast this afternoon. Ahead of this system a southwest flow aloft spreading mid and high level clouds over Washington and Oregon. This will continue through the evening and overnight. Temperatures will be milder than the past few nights with lows in the 30s to lower 40s. As the front moves onshore surface gradients will tighten with increasing southerly winds developing overnight across central and northeast Oregon. On Friday the frontal boundary will move to near the Cascades with rain in the afternoon. Elsewhere across the forecast area partly to mostly cloudy and warm with highs in the 50s and 60s. Breezy to windy over central and northeast Oregon. The upper trough and weakening front move through the region Fri night and Sat with a period of rain and higher elevation snow. Southerly winds will become westerly with locally breezy conditions. Cooler with highs only in the 40s to mid 50s. The next upper trough and front moving into the Pacific northwest Sat night with increasing clouds and precipitation reaching the Cascades by morning. 94

LONG TERM. SUNDAY THROUGH THURSDAY . The long term pattern is dominated by a deep trough slowly traveling south along the PacNW coast before moving onshore in CA midweek. This feature is coupled with persistent southwest flow aloft, allowing for moisture to spin up and around the system and develop upslope precipitation along the Cascades and northern Blues. The trough will also keep partly to mostly cloudy skies overhead as mild temperatures are expected with highs in the upper 40s to low 50s for lower elevations and low to mid-40s in the mountains, and lows near freezing for the Basin. As the system near the WA/OR coasts late Monday into Tuesday, precipitation chances will be heightened to allow for the best chance for low elevation rain, primarily during the afternoon hours on both days. As the system drops along the northern CA coast, drier air should infiltrate into our area late Tuesday into Wednesday to provide a slight dry period before the next system approaches from the northwest. Upper level flow will also be shifting from southwest to northwest by Wednesday afternoon/early evening to bring a return to upslope rain/mountain snow along the Cascades and northern Blues.

A weak system looks to be forced south through central and eastern BC early Thursday, and will pick up some Pacific moisture on its way through the interior PacNW, allowing for mountain snow chances to increase - especially for the WA Cascades. The system will be dissipating as it near the CAN/USA border, so precipitation chances are mainly expected at elevation and primarily along the western slopes of the Cascades and Blues, with little making it to lower elevations.

Snow levels should stay relatively consistent through the workweek, mainly staying between 2000-3000 feet. During frontal passages, Tuesday and late Wednesday into Thursday, snow levels will hover between 1000-2000 feet. No hydrologic concerns are currently expected due to low variability in snow levels and cloud cover through the long term. Models are in fairly good agreement on the offshore system until late Tuesday/Wednesday, where the GFS slows down the system as it moves onshore just south of the Bay Area, and the ECMWF keeps its earlier speed and because of that, pushes farther south and moves onshore along the USA/MEX border before continuing east. Observing ensemble cluster and phase space data, confidence is leaning slightly toward the ECMWF outcome. This would lead to a quicker and more southerly track of the system, resulting in faster drying behind the system and a more substantial influence from the offshore ridge FRI/SAT. 75

AVIATION. 18Z TAFs . VFR conditions currently across all sites, and will continue through the period. High level SCT/BKN clouds will build through the morning and early afternoon hours. Breezy winds are expected for central Oregon sites as wind gusts range between 20- 30 kts out of the S/SW, reaching upper bounds of this range toward the end of the TAF period. Locally breezy winds are likely this afternoon at PDT and ALW, as sustained winds hover around 10 kts. 75
