Forecast: The upper level ridge of high pressure is very strong and will continue to dominate our weather pattern likely through the end of the month. For the week and through the weekend expect low clouds and fog for the majority of the time. Some afternoons might burn off to partly sunny or mostly sunny skies but they will be the exception. There appears to be no chance of precipitation in any 5-7day forecasts right now. Temperatures will hover from the low 30's to the upper 30's. If we get a sun break we could make it into the low-mid 40's for a high temperature.

Air Stagnation Advisory: The National Weather Service in Seattle has issued an air stagnation advisory for the entire Puget Sound lowland region, in effect until 10am Friday January 24, 2014. A low level temperature inversion has formed and is creating minimal movement of the air. This will allow pollutants to increase near the surface. Burn Bans are likely and I recommend checking Puget Sound Clean Air Agency's website for the status of any burn bans. As I write this Sunday afternoon there are currently no bans in effect.

Last weekend's storm: We had a good series of storm fronts move through the area last Friday and Saturday bringing us a lot of wind, and a much needed dose of mountain snow and lowland rain. Friday - Sunday we received 1.17 inches of total rainfall, bringing the total rainfall for January so far at 2.41 inches. This however may be the total rainfall for the entire month as we are expected to be dry for the rest of the month. Winds were strong, but not severe. We had gusts in the area range from 35-40mph, I didn't see anything stronger than that recorded within Shoreline or Lake Forest Park. I was checking stations such as the Home Education Exchange station (formally North City Elementary) and the Shorecrest High School weather station.
