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) is 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 Monday) that will keep the showers around into next week.
