No winner this week. Here is my weekly weather quiz question for the last time. What is a “wall cloud?” Here is the correct answer. A wall cloud is a localized, persistent, often abrupt lowering from a rain-free base. Wall clouds can range from a fraction of a mile up to nearly five miles in diameter, and normally are found on the south or southwest (inflow) side of the thunderstorm. When seen from within several miles, many wall clouds exhibit rapid upward motion and cyclonic rotation. However, not all wall clouds rotate. Rotating wall clouds usually develop before strong or violent tornadoes, by anywhere from a few minutes up to nearly an hour. Wall clouds should be monitored visually for signs of persistent, sustained rotation and/or rapid vertical motion. I’ll have another 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.

We’ll be drying out as an upper air high pressure ridge (shaded “Arch” shape with blue arrows) builds in protecting us from any storms. A frontal system moved in bringing us some clouds with a slight chance of drizzle. Next week is looking dry, bright, and quite a bit warmer. Yesterday, June 1, was the official beginning of the Atlantic-Caribbean Hurricane season. Another frontal system will push into the Pacific Northwest Thursday, but again it looks like we’ll only see a few more clouds but no precipitation.
