Wind And More Wind
We have over two weeks of cold windy weather. It started in mid April around the time of the big wind storm. And in relation of the wind storm on April 24th, Rick Thoman wrote: "Winds this strong in the Anchorage are rare at this time of year. An unusually strong storm for the season in the southeastern Bering Sea produced southeast strong winds blowing across the Chugach Mountains. However, being April, the temperature profile of the atmosphere close to the ground was more conducive than in winter for allowing the very strong winds aloft to reach down to the ground.
