Here is my weekly weather quiz question for the last time. What is “Agglomerate?” Here is the correct answer.  Agglomerate is an ice cover of floe formed by the freezing together of various forms of ice. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer at the bottom of this page. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

An Upper Air Low Pressure Trough (Shaded “U” shape with blue arrows) pushed another frontal system shown on the days 1-3 graphic into the Pacific Northwest. The graphic for days 3-7 shows more frontal systems heading our way that will try to break through blocking surface high pressure. For mountain snow conditions at the local ski areas check out their websites or give them a call.
