An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) sits offshore and surface high pressure is near the coast. The two combine to keep our weather stable for the next couple of days. The graphics for days 1-3 show the cold front that will be approaching the coast today to move through between Friday and Saturday. The graphics for days 3-7  show that frontal system right on shore Saturday.

Note: The Autumnal Equinox occurs at 6:54 pm Saturday ushering in the Fall season.
