Watch hot day end with a thud in Port Angeles

The radical shift from relatively hot to chilly in a matter of minutes is a summertime staple along the coast and northern Olympic Peninsula when the thermal troughs give way to the marine breezes. Sometimes the temperature can drop more than a dozen degrees in just a few minutes -- one of the few areas around where such large temperature drops come without the aid of a storm or front.

The scene played out again in Port Angeles Wednesday when easterly winds pushed the temperature into the 80s, only to have the thermometer come crashing down when the west wind moving down the Strait of Juan de Fuca won the battle.

These images and temperature data are from my parents' camera and weather station they have on their deck on the bluff in Port Angeles (camera to be live to the public soon, once some bandwidth issues get straightened out).

Around 5 p.m. Wednesday, the temperature was 80.4 degrees -- very hot for their location right on the water. (The official gauge at Fairchild Airport reported a high of 85).

At 7:30 p.m., the temperature drifted down a bit to the upper 70s but now you can see the wind ruffling the Strait waters as it approaching from the west.

Then the wind hits and boom! There goes your heat wave... 15 minutes later the temperature has dropped from 75.6 degrees to 62.2 degrees. Don't try this in the Midwest, you're liable to get soaked!
