7 Day Forecast
Rain Thursday morning across Northwest Indiana was only a prelude to more severe thunderstorms through the early evening and overnight, the National Weather Service said.
Rainfall totals for Thursday morning's storm was recorded at 1.27 inches, as reported by Porter County Regional Airport. Meteorologist Matt Friedlein, of the National Weather Service, said the rest of the Region's rainfall totals averaged between three-fourths of an inch and one inch.
Storms were expected Thursday night and could produce ping-pong ball-sized hail, wind gusts of up to 70 mph, a potential for localized flash flooding and even a limited tornado risk, forecasters said.
Friedlein said Northwest Indiana would see the heaviest rain overnight.
The greatest chance for severe storms was expected along and south of Interstate 80, according to the weather service's Romeoville office.
Some of the storms could produce torrential downpours. If storms repeatedly move through the same areas, some locations could see more than 3 inches of rain, resulting in flash flooding.
Widespread rainfall totals Thursday night could be between a half inch and 1.5 inches, forecasters said.
A flash flood watch was issued for overnight Thursday to 7 a.m. Friday for Lake and Porter counties, the NWS said.
Heavy rain during a 24-hour period was expected to leave to rising water levels on local rivers, creeks and streams.
Residents should stay alert for any weather-related watches or warnings, forecasters said.
