Right now: A few thundershowers are moving through southern Indiana to the  northeast.  These showers will just skim the southern edge of our viewing area.  The colder air is already filtering in…temps range from the upper 30s in Lafayette to the lower 50s in southeastern Indiana.

Today: Temperatures continue to fall this afternoon…reaching the mid 30s by the evening commute.  This is also when our first wave of precipitation moves in, first in the form of rain.


Timing through tonight & Ice Accum.: This afternoon we will be dry and cloudy.  By the evening commute some light rain moves in…there could be some sleet that mixes in with the rain.  The colder air cuts into the system as it spreads through Indiana this evening.  By 8pm according to Forecast 8 Futurecast we see the sleet in Indianapolis and snow in northwestern Indiana.  The ice accumulation continues in southern Indiana through midnight and the ice changes to snow for Indy by that time.  Ice accumulation overnight tonight will be .10″ along I-70 and northward, .10″ to .25″ around I-70, .25″ or more in southern Indiana.

Timing the Snow & Accum.: There is a break from the snow 7am Friday, but then more snow fills in again for the afternoon and evening hours.  Total snow accumulation will be 4″ to 7″ along I-70 (including Indy), lesser amounts to the north due to the sharp cut-off, 7″ of snow or more in southern Indiana.  This is through Saturday morning.

*If there is more ice that mixes in with the system that could make the snowfall totals less.

Extended forecast: Arctic air settles in as we get a break from the winter precipitation on Saturday.  Sunday into Monday another wave moves through central Indiana, giving us a mix of sleet, freezing rain and snow.  Stay tuned for updates on totals with this system.
