Here is my weekly weather quiz question for the last time. What is a “Disdrometer?” Here is the correct answer. A Disdrometer is a piece of equipment that measures and records the size distribution of raindrops. 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 graphics for days 1-3 show the weak frontal system that moved through wasn’t a big deal. An Upper Level High Pressure Ridge takes over bringing dry and sunny weather at least for a while. The graphics for days 3-7 show the frontal systems that will be affecting the Pacific Northwest next Tuesday through Saturday.
