Another upper level high pressure ridge (the shaded “Arch” shape) is moving eastward away from us bringing the rain back as a trough of low pressure (Shaded “U” shape) moves in along the coast and a frontal system pushes through Oregon. Another storm will come in late tonight and Tuesday AM. Yet another frontal system will slide toward us Thursday increasing the rain chances.
