Indiana residents who slogged through last year's icy, snowy winter may be facing a repeat of that icy blast in the coming months.
Associate state climatologist Ken Scheeringa says the same La Nina weather pattern that brought Indiana a cold and snowy winter last year appears poised to return this winter. La Nina occurs when the central Pacific Ocean around the equator cools by at least 1 degree below normal.
Last year, La Nina combined with a warming of the ocean around Iceland and Greenland called the North Atlantic Oscillation to make Indiana's winter particularly long and cold.
Scheeringa tells The Indianapolis Star (http://bit.ly/pv5zpn ) those two weather patterns appear as though they could repeat again this winter.
He says, "When they join forces, they make us very miserable."
