What is a Chinook?

By By Steve Pool

SEATTLE - A Chinook is a fast, sinking wind that can cause dramatic increases in temperature.

These winds are somewhat common in Montana and Alberta as strong winds come down the eastern slopes of the Rocky Mountains. As the air sinks, it becomes warmer and drier.

There have been some incredible temperature changes due to these winds -- also known as "snow eaters" in those areas.

On Jan. 11, 1980 in Great Falls, MT, a Chinook wind brought the temperature up from -32 to 15 above -- in 7 minutes! That stands as the record for fastest temperature change in the United States.

But the Canadians don't miss out on this either. On Jan. 6, 1966, the temperature rose 37.8 degrees in 4 minutes in Pincher Creek, Alberta.

YouNews Almost Old Enough!! (New) Almost Old Enough!!
About a week ago I posted 3 pictures of 4 newly hatched Dark-Eyed Oregon Junco chicks. These are the same little ones, 8 days old now. They should fledge by June 1. It's amazing how quickly they grow. A week ago there was tons of room in the nest.

Each year since 1946, the Nisei Veterans Committee has held a Memorial Day Service to honor all who have died in service of their country, especially members of the 442nd Regimental Combat Team, the most highly decorated unit for size and length of service in the history of the US Military, and the Military Intelligence Service, a group credited by General MacArthur's staff with shortening the War in the Pacific by two years
