An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) slides southeastward bringing us the slight chance of showers today and a better chance Friday. The graphics for days 1-3 show the frontal system that moved through Wednesday and the next one approaching Saturday morning. A High Pressure Ridge takes over late in the week trying to calm things down, but 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 to possibly produce a bit of snow.
