Here is my weekly weather quiz question. What is the average ratio of melted liquid to actual snowfall? In other words how much melted snow (liquid amount) will equal a specific amount of snow? Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good Luck.

Another upper level trough of low pressure is moving down from the Gulf of Alaska following the one that is moved away from us. A warm front (shown in red) pushed through raising temperatures a bit and raising the snow levels above the valley floor. It is followed by a cold front that moved through the Pacific Northwest. For skiers Mt. Ashland, Hoodoo and Willamette Pass are all open.

The Winter Solstice takes place at 3:12 AM PST tomorrow and that marks the official beginning of Winter and the shortest day of the year. For more detail see The Old Farmer’s Almanac. And NO, in my opinion, I don’t think it will trigger the end of the world.
