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. Even more frontal systems (position shown is Thursday) will keep the showers around through the week.
