Here is my weekly weather quiz question for the last time. What is  an“ Artesian Well?” Here is the correct answer. An Artesian Well: In hydrologic terms, a well drilled into a confined aquifer with enough hydraulic pressure for the water to flow to the surface without pumping. Also called a flowing well. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

The graphic for days 1-3 shows the next frontal system approaching the Pacific Northwest Sunday. The graphic for days 3-7 shows the next frontal systems that will be moving into Oregon through next Friday. For mountain snow conditions at the local ski areas check out their websites or give them a call.
