- Snow develops and becomes heavy at times Sunday into Monday
- Wide range in totals across Central Indiana
- Gusty winds lead to blowing and drifting Sunday night into Monday
A Winter Storm WARNING covers much of Central and southern Indiana from 10AM Sunday to 7PM Monday. A Winter Weather ADVISORY is in effect for northern locations from 1PM Sunday to 7PM Monday. Lowest snow totals are expected in the Advisory area.
It's important to note that this system will take time to move from south to north across Central Indiana through the day Sunday. While southern areas are likely to start accumulating snow through the morning, areas along and north of I-70 may not see much accumulation until late Sunday afternoon into the evening.
Widespread snow is expected Sunday evening. At this point, some moderate snow will be possible. Due to the cold temperatures, snow will accumulate quickly.
The highest snowfall rates are expected Sunday night into early Monday. Rates of 1"+ per hour will be possible across much of Central and southern Indiana. Much lighter snow continues for northern areas.
There's still some question how far north a wintry mix may come into Central Indiana overnight Sunday into Monday. Despite surface temperatures below freezing, a warmer layer of air above may lead to a period of sleet (or even freezing rain) south of I-70. If this does develop, it would cut down on snow totals in those areas.
Given the storm track shifting a bit more to the north, we have also adjusted snowfall amounts up (especially across northern areas). Currently leaving a broad area of 5"-10"+ snowfall across much of Central Indiana. Think there will be a band of double digit snow totals. Exactly where that band sets up may not become apparent until we get into the storm.
Winds increase Sunday night into Monday. Gusts between 30 and 40 mph will lead to a blowing and drifting of snow. This will make it difficult for crews to clear roads. If you can, delay travel until after the storm. Power outages are also possible. Snow lasts into Monday morning, but should move out of the area by the afternoon.
Very cold temperatures remain in place for the foreseeable future. Factoring in the wind keeps wind chills in the teens Monday.
