Synopsis: Low pressure will continue to track across the eastern Great Lakes this afternoon. A warm front will lift northward across our area. A strong cold front will then cross our region this evening. Weak high pressure briefly moves in by late Saturday before the next low pressure system crosses the area west to east on Sunday. High pressure moves back in to start next week before the next system moves in next Tuesday. A frontal boundary looks to then stall in the general vicinity of the region through the remainder of next week as additional waves move through along it.
