Winter makes another comeback later this week. From the NWS:

.LONG TERM /Friday through Monday night/...
Issued at 252 AM EST Tue Jan 24 2017

Central Indiana will see a few upper waves drop southeast across the
area in mean western ridge and northeastern trough pattern. This
will result in slightly below seasonable weather with snow showers
or flurries from time to time. That said, moisture will be lacking
somewhat, so will not go any higher than the regional blend small
chance pops over all or parts of the forecast area Friday and Sunday
and Sunday night.

Upper ridge should allow for dry and seasonable weather next Monday.
