UPDATE: The Winter Weather Advisory has been expanded across central Indiana from 10 p.m. Friday until 7 a.m. Saturday. A yellow travel advisory has been issued for Hamilton County, meaning routine travel or activities may be restricted in areas because of a hazardous situation.
The evening commute should remain mostly dry. But conditions will change throughout the night.
Precipitation will be light and really does not ramp up until later tonight. A quick look at forecast radar 10 PM Friday from latest RPM model is posted below.
Light snow accumulation of up to 1" and a light coating of ice is possible until temperatures climb throughout night especially over north central Indiana. I'm posting the latest snowfall possibility through 8 am Saturday.
It's after 2-3 am that the wintry mix changes to rain from south to north. Travel conditions will improve for motorists by sunrise Saturday area-wide. If travelling further north to northern Indiana, conditions will be slick through noon.
