Indiana starts the day under crisp air and wet, slushy pavement as light flakes drift across central counties and visibility dips near open fields. Skies stay gray, and temperatures hover near the freezing mark, giving roads a slick feel as drivers roll into the late morning.

According to the National Weather Service, patchy snow continues today as a colder airmass settles in across the Midwest. Accumulations stay light, but pavement may refreeze during the afternoon as melting snow quickly hardens. Plan extra time if traveling, especially on shaded stretches of U.S. 31, I-65, and rural routes where black ice forms fastest.

Meteorologists now track a broader winter push developing upstream. A stripe of accumulating snow stretches from the Northern Plains toward the Midwest, and this band is expected to slide toward Indiana through Saturday. While exact placement still shifts, models hint at a “winter tease” for central and eastern Indiana with scattered snow by Saturday afternoon and a colder, wind-driven feel by Sunday.

By Sunday, biting air sweeps in from the Upper Mississippi Valley, dropping highs into the teens and low 20s. Any snow that fell earlier in the weekend may stick firmly as wind chills dip below zero. Watch for icy patches on neighborhood streets, parking lots, and bridges where freezing will be quick and persistent.

A more active pattern rebuilds lake-effect snow north of Indianapolis late Saturday into Sunday, with heavier pockets possible closer to the Indiana–Michigan line. Those traveling for early holiday plans should expect rapidly changing conditions.
