Sorry no winner this week. Just in case you missed it, here for the last time is my new weather quiz question for this week. On average there are about 50,000 of these per day over the world and 10 million of them in a year. What kind of weather event am I describing? The correct answer is lightning. I’ll have another 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.

_______________

The upper airflow is bringing much colder air toward us both aloft and at the surface.  Another trough of low pressure will slide in along the coast sending more storms our way and dropping snow levels in the mountains. A complex frontal system will be moving into Oregon from British Columbia through Washington bringing with it cold air that will drop snow levels well below the passes. An arctic air mass will be pushed South by a strong jet stream (see airflow graphic above) and will move down behind that cold front Sunday night through Tuesday giving us the possibility of some snowflakes even reaching the Valley floor.

_______________

Advisories: A WINTER STORM WARNING IS IN EFFECT UNTIL 10 PM THIS EVENING ABOVE 2,000 FT. FOR EASTERN CURRY COUNTY AND JOSEPHINE COUNTY OF OREGON. A WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 7 PM TONIGHT THROUGH 7 AM SUNDAY ABOVE 2,000 FT. FOR JACKSON COUNTY OREGON.
