It's our biggest cold outbreak so far this season, and it arrives with snow overnight. The snow will be LOW impact, but the cold temperatures will be a BIG impact.
Let's time if out and look at the snowfall amounts. Follow along with our Futurecast maps below.
Dry and "mild" this afternoon in the upper 50s and low 60s.
Rain showers arrive ahead of the front this evening, mainly after 8pm (sooner in S. Indiana).
The rain turns to sleet/snow generally after midnight for Louisville (again, sooner north). The best chance of snow will be from Midnight to 5am. Snow showers will linger south until around sunrise Tuesday morning. The snow will be melting on contact with the roads, but a dusting possible on decks, porch, grass and other elevated surfaces.
Temperatures will be near freezing tomorrow morning with gusty winds, pushing winds chills down to the 20s. Highs only in the 30s tomorrow, with colder wind chills. Heavy coats needed!
