We have a Winner! Congratulations to Vanessa. You are the winner of this week’s weather quiz question.

Phillip Roberts answered correctly too, but Vanessa was first.

Here is my weekly weather quiz question repeated for the last time. Define the term “deliquescence.” here is Vanessa’s correct answer. “deliquescence: the ability of a substance to attract and hold water molecules from the surrounding environment.” Humid days are hazy because many particles in the air absorb water vapor and grow large enough to scatter all light waves as humidity increases. When the humidity is less than 100%, the growth and added water absorption of a particle is called “deliquescence.” 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.

A cold front is moving in bringing clouds and a chance of rain, but a high pressure ridge (“Arch” shape on the jet stream) will bring back the fog and freezing fog to start the workweek. An upper air trough of low pressure (“U” shape on the jet stream) will soon after return the clouds and chances for rain.
