Sorry no one correctly answered my weekly weather quiz question. What is the difference between  freezing rain and sleet? Here is the correct answer. Freezing rain is rain that falls as water and then freezes to surfaces that are below freezing and sleet is made up of small irregularly shaped pieces of ice falling from the sky. I’ll have another Weather quiz question for you on Monday. The first person to post the correct answer will win one free week of personalized forecasts tailored to your needs.

High Pressure (the arch-shaded and with blue arrows-moving ashore) is moving in to replace the trough of low pressure moving eastward away from us. High pressure is also moving in at the surface which will give us some more sunshine. A couple of storms will move through Oregon next week.
