Here's the latest discussion from the National Weather Service out of Indianapolis:
.SHORT TERM...(Tonight through Friday night) Issued at 317 AM EDT Wed Oct 16 2019 Models are close enough that the National Blend of Models initialization was accepted for most items. Quiet weather will continue throughout the short term with high pressure and upper ridging building in. Low clouds will erode tonight, but models often overdo how fast the clearing will occur. Went slower than the blend. Mostly clear to partly cloudy skies will then continue through the remainder of the short term. Temperatures will gradually moderate through the period. The NBM looks a bit fast on the warm up on Thursday, so trimmed a bit. && .LONG TERM /Saturday through Tuesday/... Issued at 323 AM EDT Wed Oct 16 2019 Two frontal systems are expected to move across central Indiana during the long term. The first is a weaker system from Saturday afternoon to the early morning hours Sunday. The Euro is more aggressive on rain with this weak front than most of the other models are showing, plus the trend for rain Saturday has been diminishing as we get closer. For these reasons, kept PoPs low in this timeframe. Most of Sunday should be dry before the next frontal system approaches the area starting late Sunday night. A better chance of rain and thunderstorms across the region exists from early Monday morning through Tuesday morning ahead and along an approaching cold front, with the potential for some of the storms becoming strong to severe at times. Warm air advection will keep temperatures above normal for most of the long range before dropping back down to normal by Tuesday behind the cold front. Gustier winds are expected during the day Monday and Tuesday with wind gusts of up to 25 to 30 kts. Otherwise, winds will generally be 3 to 8 kts out of the south.
