Flood — Jan 31, 2025

A closed upper level low slowly moved out of SW CONUS and opened into a positively tilted trough as it approached KY. Large scale flow ahead of the lows approaching cold front, pulled gulf moisture northward.

A MCS developed in the Upper Mississippi Valley and continued to push southeast towards the Commonwe...
