Here is my weekly weather quiz question for the last time. What is “AWIPS?” Here is the correct answer. AWIPS is Advanced Weather Interactive Processing System. This system replaced the Automation of Field Operations and Services (AFOS). This system allows the operator to overlay meteorological data from a variety of sources. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

The weather is looking perfect for the Prefontaine Classic today. The whole long Memorial Day Holiday Weekend is looking bright, dry and warmer.
