Here is my weekly weather quiz question for the last time. What is a “Dart Leader?” Here is the correct answer. A Dart Leader is a faint, negatively charged channel that travels more or less directly and continuously from cloud to ground. (It moves down and the lightning flash moves from the ground up.) I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.

An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) slides southeastward bringing us the better chance of showers today. The graphics for days 1-3 show the frontal system that will through today and Sunday. A High Pressure Ridge tries take over late in the week trying to calm things down, but it brings us air cold enough to possibly produce a tough of snow at lower elevations. An Upper Level Low Pressure Trough (Shaded “U” shape with arrows on first graphic) returns the precipitation. The graphics for days 3-7 show the frontal system to our north pushing colder air our way Sunday into Monday to possibly produce a bit of snow, then a frontal system coming through next Friday.
