Sorry, no winner again this week. Here is my weekly weather quiz question just one more time. How long can a lightning bolt be? Here is the correct answer. Recent research from Vaisala-GAI’s LDAR and LDAR II lightning detection networks show that lightning can travel 60 miles or more. The longest bolts start at the front of a squall line and travel horizontally back into clouds trailing behind the squall line. The longest bolt they have seen to date was 118 miles long in the Dallas-Ft. Worth, TX area. Since 3-D lightning measurements are relatively new, scientists are learning more every day and these numbers may change. I’ll have a new weekly weather quiz question for you starting next 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.

Advisories: NONE AT THIS TIME.
________________
The Jet Stream airflow is still pushing storm systems our way. A frontal system slid through the Pacific Northwest overnight and another one that will slide through on Sunday will increase the clouds and the chance of rain by Sunday afternoon. We are now in the space between them so we will be dry for the most part for the rest of today and Sunday morning.
