| Area Forecast Discussion National Weather Service Medford OR 356am PDT Thu Mar 30 2023 Although the large upper level low has moved well out of the area, a few weak shortwaves within the northwest flow aloft will produce another chance for showers this afternoon, especially given the increasing lapse rates due to warming at the surface. Most of these showers will occur along the coast and in the coastal ranges, and along the Cascades, where general west flow will produce the strongest orographic uplift. Diminishing shower activity is likely to continue into the evening and perhaps persist overnight. The next front will approach the area Friday, and move onshore Friday evening into Saturday morning, followed by a second front and the arrival of a deep upper level trough from the northwest on Sunday. The result will be a cool and wet weekend for most of the area. For the mountains and east, the snow levels will be low enough to impact the majority of the area, and the latest ensemble probabilities indicate that areas from Willamette Pass to Crater Lake have an 80-100% chance of at least another foot of snow by early Monday. Parts of the Curry Coast range and western through south-central Siskiyou County are similar. For the inland west side, snow levels look like they'll start near 3000 feet Saturday then lower to near 2000 feet Sunday. Some areas down to 2000 feet may see some accumulation, so winter travel is possible for the low elevation passes Sunday. The upper trough should keep cold cyclonic flow over the region with continued rain and snow showers through late Tuesday. Near- freezing or sub-freezing morning temperatures also look like a good bet for much of the western valleys for successive days beginning Monday, and we can not rule out low elevations snow on Monday or Tuesday mornings as showers persist behind the departing trough, much like the last several northwest trough events of the past several weeks. The majority of the ensemble means suggest the trough axis will head east Wednesday into Thursday with drier, warmer ridging moving in, at least for a short time. -BPN/Stavish Marine Updated 230am PDT Thursday, March 30, 2023...Seas will continue to diminish into early Friday as high pressure briefly builds over the area. Winds and seas will increase Friday, with gales possible ahead of a strong cold front on Friday night. The pattern is expected to remain active this weekend into early next week.
