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) moved in along the coast and a frontal system is pushing southward through Oregon. Another storm will come in late tonight and Tuesday AM. Yet another frontal system will slide toward us Friday increasing the rain chances. See the pattern here of frontal systems that will march through the Pacific Northwest.
