January 10 will mark the beginning of a change in weather patterns. High pressure cells will be developing just off the coast in the Pacific Ocean and in the arctic, bring a slow end to the continuous rain and mild temperatures.
It will be a lot dryer and cooler. There will still be a few showers and milder times for the coast. However, there won’t be any record breaking mild temperatures.
Because the high pressure cells will be developing very close to the coast, it is unlikely for any snow to fall in lower elevation areas of the Pacific Northwest.
Based on teleconnection forecasts from NOAA and our own calculated teleconnections, the high pressure systems will move further away from the coast, and develop in the arctic sometime around mid-late January. Snow will be possible for coastal Pacific Northwest under those conditions.
