INDIANAPOLIS — This winter storm is well underway for central Indiana. So far today, the area of low pressure has been to our southwest in Kentucky. As this tracks into southern Indiana over the next few hours, colder air will become more dominant, which impacts the "wetness" of the snow and increases snow ratios.
As of 7 a.m., Indianapolis has received 0.9" of snow, but with very low snow ratios. That means temperatures have been slightly above freezing at the surface, which limits snow accumulation. As the ratio increases, bands of snow will become heavier and begin higher accumulations through the mid-morning.
Snow will be consistently heavy through the lunch hour and begin tapering off in the afternoon. Look for road conditions to continue to worsen until the snow lets up.
As the heaviest snow exits, this wet snow will begin to compact, allowing for roads to clear quicker. Road conditions should improve quite a bit by this evening.
Most spots around the metro are looking at 5+ inches with slightly higher amounts — up to 8 inches — west and north of the metro. With more of a mix to areas south, snowfall totals will remain lower.
