- Frost/Freeze04/06/2007
Ohio
$620K damage
What happened
Unseasonably warm temperatures for an extended period of time in March allowed much of the Ohio Valley to begin its agricultural growing season early. In early April, a cold snap with low temperatures dropping from the upper teens to middle 20s threatened agricultural interests across the region.|The full effect of these weather extremes is still yet to be known, and will not be known until the fall harvest can be compared with yields from previous years. The initial estimate of 5.58 million in crop damage was split evenly between 9 Indiana counties.
