The National Weather Service has upgraded over half of Southern Indiana to a Winter Storm Warning which means winter weather is expected. Rain showers will begin transitioning to a rain/snow mix this afternoon before becoming all snow. A flash freeze is likely as a result of temperatures crashing from the 40s to the single digits to near sub-zero. Snow accumulation is expected ranging from 2-4 inches area wide with locally higher amounts where snow squalls or bursts of heavy snow form. The change over to wintry precipitation is expected in Western Southern Indiana after 2pm CST./3pm EST. and closer to 5pm CST./6pm EST. in Central Southern Indiana and around 7pm CST./8pm EST. in Eastern Southern Indiana.
Aside from the snow is dangerously cold temperatures. Tonight's low is -4 degrees with wind chill values ranging from -25 to -30 degrees.
