Re: franklin going away, SAT brought a question

Actuallly DM, the hite line that Franklin is on is the trough exiting. The Dark area in the Ohio valley is ridging/higher pressure. The trough or cold front is pushing Franklin out. Sometimes storms duck under the cold front and head westward underneath the building ridge (dark area). Associate troughs with areas of lower pressure/Moisture (white areas on the picture) usually amplifying or rising air,and ridges with clear skies (dark areas on picture) and sinking air/drier conditions.
