Wider weather episode

Several rounds of showers and thunderstorms prompted a widespread flash flood problems across the Ohio River Valley on April 2nd to April 3rd. The synoptic pattern across the CONUS was a slow moving and deep elongated trough over the Great Plains phasing with a ejecting trough over the Midwest that created an area of converging moisture over eastern Ohio and western Pennsylvania. Overall, over a span of 4 days, four to five an half inches of rain fell across the region. Not only was small tributaries impact, but the main river reached moderate flood stage.

Along with flooding, there was a brief period of severe storms that tracked along eastern Ohio on the evening of April 2nd. A number of tornadoes touched down and were surveyed. Special soundings released by PBZ and ILN depict effective instability over eastern Ohio (1200J/kg to 1700J/kg), effective low-level shear (+50kts), and low-level helicity (300m2/s2) for rotating updrafts just before storms tracked through the area.
