Here is my new weekly weather quiz question. What is the difference between Doppler Radar and the older generation radar? Please post your answer as a comment after the forecasts on  this page. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.

The upper air flow (yellow jet stream and dark colors for winds) shows a  trough of low pressure a (“U” shape offshore) sliding Eastward into the coast as a frontal system moves slowly through the Pacific Northwest. Notice that the jet stream airflow moves so that it brings the colder air from the north and northwest toward the middle and end of the week into New Years Day.
