Here is my weekly weather quiz question. What is a “Dry Thunderstorm?” 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.

________________

We are seeing an increase in marine airflow which cools us down. The Upper Level High Pressure Ridge has weakened enough to allow the chance in surface air movement and an Upper Level Low in the far Southwest U.S. keep the chance of getting wet with us for another day. The graphics for days 1-3 show surface low pressure moving eastward. The graphics for days 3-7 show a series of storm systems that will approach and try to move through the Pacific Northwest Saturday through next Wednesday.
