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 will continue to send storm systems our way producing more rain. A frontal system will slide through Sunday increasing the clouds and the chance of rain. Another frontal system will bring rain Tuesday, then things will dry out for a few days.
