A cold front over the Great Lakes will move southeastward, reaching Lake Erie tonight where it will stall. A wave of low pressure will move northeast along the front Friday and Friday night bringing widespread rainfall to the area.
As the low pressure system moves east of the area late Friday night or early Saturday, the front will be pulled southward across the area. A much stronger system will develop across the southern Plains Saturday, and move northeastward into the eastern Great Lakes on Sunday. The front will return northward as a warm front on Saturday, ushering in warmer and more humid air. Heavy rain will become increasingly likely on Saturday as deep moisture streams across the area ahead of the approaching system. The combination of heavy rain and rapid snow melt could lead to flooding problems this weekend.
