A high pressure ridge (“Arch” shape on yellow line) is pulling away from us and a trough of low pressure (“U” shape on the yellow line) will be taking over returning the wet weather pattern. A frontal system moves through with the chance of rain. There will be even more frontal systems (position shown is Sunday) that will keep the showers around through the weekend into next week.
