Here is my weekly weather quiz question. We all know that tornadoes are dangerous and can kill. What were the deadliest tornadoes recorded in the U.S.? 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.

A short-lived high pressure ridge (shaded “Arch” shape) has taken over just in time for Thanksgiving bringing out the sunshine and drying us out. A frontal system (shown still well offshore) and an upper level trough of low pressure (moving out of the Gulf of Alaska) will push into Oregon Friday bringing back the wet weather, but that won’t last too long. Again, please make sure the storm drains on your street are clear of debris so they will have a better chance of staying clear when the next wave of rain hits. Building high pressure at the surface (blue “H”) and aloft, will clear us out again Sunday into early next week. In other words we’ll be on an interesting roller coaster ride for a while fighting between clouds and sun and wet and dry.
