The National Weather Service has confirmed two tornadoes touched down in Indiana Tuesday, one in Fountain County and one in Tippecanoe County.
A tornado watch is in effect until 8 p.m. for south central Indiana.
The warning issued Tuesday morning covers an area from Terre Haute to Indianapolis to Greensburg, extending to the Ohio state line.
Continued flooding across northern Indiana has caused widespread road closures and warnings that it could take several days for high waters to recede.
The National Weather Service says up to a quarter-inch of ice and 2-4 inches of snow will create hazardous conditions across much of southern Indiana.
Officials in central and northern Indiana are warning people that dangerously cold temperatures being felt in the state can quickly cause frostbite.
Meteorologists say expected snowfall late Friday or early Saturday just might stick around long enough for a Hoosier white Christmas.
Recorded temperatures haven't been as high as what's forecasted for the next few days since 2013, when they hit nearly 96 degrees.
The tornadoes impacted Clinton County, Crawford County and Jefferson County.
Indianapolis received a record rainfall total for April 29 of 1.99 inches. The old record was 1.71 inches set in 1970.
