Morning lows in the mid to lower 40's coupled with the still relatively warm waters of the Sangamon River produced a local steam devil opportunity on Wednesday. With a reinforcing shot of cold air forecast for the weekend that will result in lows in the 30's by Monday, this phenomena will be widespread on area waterways. The best time for viewing these ghostly whirlwinds is anywhere between dawn and around 9:30 AM while the sun angle is fairly low and winds are somewhat calm.
