Freezing Rain & Drizzle
Snow fell in many areas Friday night December 16th-the morning of Saturday December 17th, along with a wintry mix of freezing rain/drizzle, and even some sleet. Reports from the morning of the 17th were generally less than 0.1" for the Northern Indiana Forecast Area (IWX). This led to minor ice accumulations on trees, cars, and other elevated surfaces. Patches of ice were reported from the highways, with several accidents occurring. To see photos of the ice, click on "photos & Video." Near Indianapolis, icy totals were much higher and wreaked havoc on the roads in the area. Motorists were stranded on the highways, and there were numerous reports of serious accidents.

Arctic Blast
An unseasonably strong blast of arctic air invaded the region behind the system. A combination of fresh snow pack, clear skies and winds under 10 mph set the stage for rapid temperature drops with nearly every reporting site at or below zero. Several locations across northern Indiana into far southern Lower Michigan seen air temperatures drop into the -10 or lower range. A list of low temperatures for several locations can be found below. Despite winds being generally light, even a 4 to 6 mph wind was sufficient to make it feel 5 to 10 degrees cooler than the air temperatures. The second list shows the coldest wind chill readings. Record low temperatures were broken at both South Bend and Fort Wayne for the 19th of December.

Environment
A low pressure system moved through the area, bringing the wintry mix of precipitation. At the upper levels, a trough was moving from west to east. High pressure built in rapidly behind the low, bringing in much colder air, gusty north-northwest winds, and lake effect snow.

Warm air aloft allowed for mixed precipitation to occur along the frontal boundary Friday night into Saturday. Saturday night into Sunday, cold air filtering over Lake Michigan brought lake effect snow showers to the northwest portions of our forecast area.

Cold air filtering in behind the low pressure system and good wind convergence on the lake helped aid in the development of a lake effect snow band on Lake Michigan.
