From the National Weather Service in Indianapolis:
The calendar turns to March today, but this weekend will provide yet another reminder that winter is still very firmly in control over the Ohio Valley. A significant winter storm will impact central Indiana and the surrounding region during the second half of the weekend. Precipitation will be likely as early as tonight, falling as snow over north central Indiana, with a wintry mix of snow, sleet and freezing rain further south. Snow will become the predominant precipitation type along the I-70 corridor and points north on Sunday and Sunday night. Sleet and freezing rain will mix in with the snow over southern portions of central Indiana during the day Sunday south before transitioning to all snow Sunday night. Precipitation will end early Monday morning as the system exits the area and colder air filters in.
At this time, total snow accumulations of 5-7 inches are possible over northern counties, with 6-10 inches along the I-70 corridor. Over southern portions of central Indiana, 4-8 inches of snow/sleet will be possible with the potential for ice accumulations up to 0.25 inches from Vincennes northeast through Bedford and Greensburg.
Subtle fluctuations in the storm track could have significant impact on resultant precipitation types and amounts. Stay with NWS Indianapolis and local media outlets for forecast updates on this winter storm. Be prepared for difficult travel conditions and significant snow and ice accumulations beginning tonight and continuing into Monday morning.
