Check out my latest Eugene Daily News Weather Or Not column: Not Much Winter Weather Until Now. What’s going on?

Here is my weekly weather quiz question. What is  “Deep Percolation Loss?” 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 Low Pressure Trough (Shaded “U” shape with arrows) slides slowly eastward continuing the flow of colder Arctic air coming through Canada into the Northwest. Add that in the moisture that will be moving in and there’s the chance of some more snow. This time it might actually stick on the ground in the valley. The graphics for days 1-3 show the next frontal system that will be offshore Wednesday. The graphics for days 3-7 show a frontal system that will slide along the Pacific Northwest coast Sunday night through Monday.

Note: With the moisture remaining on the roadways and the cold temperatures you need to watch out for slippery road conditions. This storm most likely will give us a real snowfall down to the valley floor so please drive extra carefully.
