Forecast Models Indicate Winter's Wrath Could Be Potent

The long-range forecast indicates that Indiana could be in for another dose of wild winter weather this season.RTV6 chief meteorologist Kevin Gregory said long-range forecasts should always be taken with a grain of salt, but forecast models are showing a weather pattern that's conducive to below-average temperatures and more precipitation, a recipe for waves of snow and ice."Indications are that we may repeat last winter in Indiana with more storms than average, above-average precipitation and significant cold air outbreaks," Gregory said.The forecast is similar to the kind of weather central Indiana had last season. The first snowfall hit on Dec. 1, and temperatures plunged into the single digits by Dec. 6.Indianapolis had 28 inches of snow in December and January alone. The city averages 26 inches of snow for the entire winter.
There wasn't much snow in February last season, but freezing rain events mixed with snow made it a tough month, too."Indications are that La Niña, a weather pattern that results from cooler-than-average temperatures in the central Pacific Ocean, will form again this year," Gregory said. "La Niña typically brings above-average precipitation and below-average temperatures to the Hoosier state."While patterns can shift or not be as strong as expected, forecasters use what they call teleconnections to increase confidence in long-term forecasts.
