As a low pressure system passes through Indiana we can expect some colder temperatures that what we have received these past few days. There will be some slight warming on Saturday as we get some warm air pushing from the south. The northern part of the state will see temperatures fluctuate around freezing temperatures while the middle of the state will see mid 30s to 40s. As for southern Indiana they are seeing the strongest part of warm advection over the next few days.
Looking into Sunday there seems to be in increase in the relative humidity along with instability in the atmosphere. Temperatures will be above freezing at the surface so there is a chance of snow Sunday morning that will change over to rain as it moves across the state. The event is followed by a cold front that will enter the state from lower pressure moving in extending from Canada.
