An Upper Level High Pressure Ridge (“Arch” shape) Known as a “Omega Block” is keeping our weather pattern stuck for a while. The graphics for days 1-3 show the next cold front that will move in tonight and Sunday. Sorry Mom. The graphics for days 3-7 Tuesday through Saturday show a complex frontal system moving into Oregon Monday, then another complex frontal system will be offshore then pushing into the Pacific Northwest between Friday and next Saturday.
