Advisories: NONE AT THIS TIME.

A high pressure ridge (“Arch” shape on yellow line) has moved away and a trough of low pressure (“U” shape on the yellow line) is taking over. A frontal system pushed through to the southeast dragging rain along with it. There will be even more frontal systems (position shown is Thursday) will keep the showers around through the week.
