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.

An Upper Level High Pressure Ridge (Shaded “Arch” shape with blue arrows) is moving away allowing an Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows)  to take over as the workweek begins. The graphics for days 3-7 show that no frontal systems will move through the Pacific Northwest next Wednesday through Sunday. The rest of the long Memorial Day Holiday Weekend is looking good, just not quite as warm as I expected.
