A major winter storm is setting its sights on Indiana, threatening to bury parts of the state with mounds of snow and other portions of Indiana with crippling ice.A winter storm watch is in effect for most of the state from Monday night through Wednesday evening. A blizzard watch was posted for parts of northwestern Indiana. Check: Watches, Warnings | Two waves of precipitation are expected to roll through Indiana, with the first beginning late Monday evening. The Interstate 70 corridor is expected to be a dividing line during both waves, with snow falling north of that area and freezing rain generally along and south of I-70.In far southern Indiana, temperatures are expected to be warm enough for most of the precipitation to fall as rain.A strong low-pressure system that will track to the south of Indiana will bring both waves of the wintry mix through.There could be a lull in the precipitation for a while on Tuesday before the second, stronger wave moves in.This setup could cause a prolonged period of freezing rain in the Indianapolis area and in other parts of the region under the watch.In areas that receive mostly snow, accumulations could be quite heavy, with storm totals that could exceed a foot. The Lafayette and Kokomo areas appear in line to receive more snow than ice.For areas that receive primarily freezing rain, ice accumulation could be significant. Up to an inch of freezing rain could fall in the Indianapolis area before the precipitation changes to snow as the storm system moves away on Wednesday. Several inches of snow could fall in the Indianapolis area on Wednesday.There is a potential for widespread downed trees and power lines in areas that receive primarily freezing rain because winds could gust up to 35 mph on Wednesday as the precipitation changes to snow across the entire area.A lot could change in the next day or two as the storm system forms and begins moving through Indiana. Changes in the track of the storm system could significantly alter the forecast. Stay with Storm Team 6 and TheIndyChannel.com for the latest winter weather information.
