Cold front still coming...possible snow!

Lots of rain overnight, some areas have reporting 3-5” which has cause several issues this morning, Public Works reports they have been very active most of the night. As I write this, Miami Foley road has water covering both lanes at MP1, as does North Fork Rd., Foss Rd had a land slide and the road is closed, other land slides include Resort Dr, MP 2 partially blocking, and others are happening but things are very dynamic right now, changing moment by moment as they get cleared and others happen.

The heavy rains have also affected the rivers this morning, last reading the Nehalem was at 11.08 and cresting but forecasted to rise to 13.04’ later this morning, Action is 12.0 and Flood is 14.0. The Wilson River was at 9.69 (and cresting) and forecasted to crest at 11.26’ later this morning, Action is 10.5 and Flood is 12.0’. Obviously I will be monitoring this closely but my thinking is the rivers levels will fall until the next batch of rain then rise again briefly, but be below forecasted levels and below Action Stage.

More wet and breezy today as the cold front continues to develop and approach the coast. Currently the freezing level is near 4000’ and our temperatures are running in upper 40s across the area with light rain. We can expect another burst of rain as the front pushes through but the satellite picture suggest to me that the main surge of moisture and winds will pass us to the south. Once the front get through later today or tonight, the temperatures will start to fall until reaching a low of 35 by early morning. More showers are expected tomorrow with the snow level down near 500’ then rising in the afternoon to maybe 1000’ before falling again in the evening and we could see a rain/snow mix after 4pm, or snow overnight, with any remaining showers but little to no accumulation is expected. Wednesday night and Thursday night the lows will be near freezing but there is a decreasing chance of showers into Thursday and Friday. New Years Day we could get some sun breaks, high near 47, low near 35 as high pressure builds in though we will still need to watch a system forecasted to move into California next Friday into the weekend.
