SYNOPSIS

The region will be between high pressure to the north, and a trough of low pressure over the coastal waters through Sunday. This trough will sink further to the south early in the week, as high pressure builds closer to the area. The gradient between the trough and the high will yield elevated conditions. A frontal system will drop south into region mid week, enhancing chances for showers and thunderstorms from mid to late week.
