Advisories: NONE AT THIS TIME.
________________
A weak high pressure ridge (“arch” on the orange jet stream line) will start to strengthen up again and give us some dry days. High pressure at the surface will combine with the upper air ridge to clear us out for some sunshine Monday and Tuesday, really. Another upper level low (“U” shape on jet stream line) will set up off the coast and a frontal system will move in to possibly bring back the rain by the middle and end of next week.
