Here is my weekly weather quiz question for the last time. What is the “NAO Index?”  Here is the correct answer. The NAO Index measures the anomalies in sea level pressure between the Icelandic low pressure system and the Azores high pressure system in the North Atlantic Ocean. When the NAO is in its is positive phase (+NAO), the northeastern United States sees an increase in temperature and a decrease in snow days; the central US has increased precipitation, the North Sea has an increase in storms; and Norway along with Northern Europe has warmer temperatures and increased precipitation. When the NAO is in its negative phase (-NAO), the Tropical Atlantic and Gulf coast have increased number of strong hurricanes; northern Europe is drier, and Turkey along with other Mediterranean countries has increased precipitation. I’ll have a new weekly weather quiz question for you starting Monday. 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.

large upper level low (Shaded U shape with blue arrows) is still controlling our weather.  A frontal system moved through the Pacific Northwest. There will be a short break on Monday as upper level high pressure drys us out for a day. Next week another frontal system will approach the Oregon coast returning our wet weather. Here comes a frontal system next Thursday to keep the rain falling.
