Be prepared for snow covered roads and slick surfaces. * ADDITIONAL DETAILS...An active storm track will continue to produce accumulating snow across the passes in the Cascades into this weekend. However, there are two time periods when snow levels appear likely to rise to 5000-5500 feet and be far enough above the passes to temporarily limit snow accumulations. The first window where snow levels will rise above the passes appears most likely to occur between 3 AM Friday and 9 AM Friday. Another round of warmer air aloft will most likely push snow levels above the passes Friday night as well.

Hydrologic Outlook issued December 26 at 12:15PM PST by NWS Portland OR

3 months 4 weeks ago
ESFPQR A series of systems will continue the wet weather pattern of late across northwest Oregon through the weekend. This will lead to rises on rivers and creeks through at least Sunday, December 29th. There is currently a 30-50% probability that several rivers in northwest Oregon including the Siuslaw River, the Mohawk River, the Marys Rivers, the Luckiamute River and the Pudding River will reach minor flood stage over the next week. Heavy rainfall may also lead to ponding of water, general lowland flooding and localized urban flooding, especially in low lying areas or other areas with poor drainage. Heavy rainfall will also increase the potential for landslides and debris flows in areas of steep terrain. The exact track of these upcoming storms will influence rainfall amounts, and thus the potential for flooding. There is a 10% chance that the southern Willamette Valley receives 2-3" of rain and the adjacent higher terrain of the Coast Range and Cascades receive 3-5" of rain late Saturday into early Sunday. This scenario would likely produce more widespread flooding issues. Shifts in storm track can change the current outlook, so be sure to monitor weather.gov/portland for the latest weather updates, as well as any watches, warnings, or advisories that may be issued.
