Why A North Wind on Sunny Days?

SEATTLE - Karen in Greenwood wondered why, while riding her bike in the evenings on sunny days, there's a warm, north wind. However, in the winter, a north wind usually brings colder air.

A north wind in Puget Sound usually signals that we have our winds coming from the offshore direction, instead of our usual marine-born winds. In the summer, that's a double-whammy of pulling air from the hotter interior of Eastern Washington and southern B.C., plus holding our cooler ocean breezes at bay.

In the winter, the north winds can bring the arctic air usually entrenched in Eastern Washington and southern B.C., while keeping the relatively warmer ocean breezes away.

The pattern is caused when we have a large area of high pressure further inland that pushes the air out to sea. It'd be more of a northeast wind, but the Cascades and Olympics funnel them so it's nearly due north through the Seattle area.

This was a once-in-a-lifetime shot of a brilliant sunrise on the water of Poulsbo. When I saw the pink light streaming into my window early that morning, I ran outside to capture this photo. Once I saw the photo, I realized that the sunrise created a fire and ice effect that was stunning.

Driving toward Silverdale on Hwy 3, from brilliant fall sunshine, into this churning black storm, was unlike anything I've witnessed in Washington. Sheets of rain, gusts of wind, and a completely black sky overtook the area, while the periphery stayed sunny.
