Messy mix tonight, icy commute FridayBy
A powerful winter storm system is on its way to central Indiana. Eighteen states from as far west as Colorado, north to Minnesota, south to Arkansas and east to North Carolina are under winter weather advisories, winter storm watches and winter storm warnings. Up to a foot of snow is likely across the Great Plains and in the mountains in southern Colorado.
Closer to home, snow develops across western Indiana around 6pm and will be in Indianapolis between 7 and 8 pm. Snow will mix with sleet and freezing rain by 11pm. Due to southerly winds, temperatures will rise after midnight and our mixed precipitation will change to freezing rain after 2am and continue through 8am. All of central Indiana will receive a quarter inch of ice during that time frame.
Along with the ice we will also have minor snow accumulations. From Lafayette to Kokomo to Muncie, 2-3″ of snow is likely. From Greencastle to Indianapolis to Zionsville to Richmond, 1-2″ is likely. From Bloomington to Columbus to Seymour, an inch of snow is likely. The combination of ice and snow will coat the roadways before the Friday morning rush hour and will cause numerous school delays and closings. Trees and power lines may also be taken down by the weight of the ice.
A Winter Weather Advisory is in effect from 7pm tonight through 10am Friday for all of central Indiana. Due to the amount of ice expected, the National Weather Service may upgrade us to an Ice Storm Warning this afternoon.
