Mon evening forecast – Jan 19, 2026 INDIANAPOLIS (WISH) — A brief warmup is ahead before we potentially lock in on another arctic blast. Cold weather advisories remain in effect until 9 AM Tuesday morning. Monday night: Very cold and mostly clear. Lows in the single digits with sub zero lows. Tuesday: Warmer, but still cold under mostly sunny skies. Highs in the mid 20s. Wednesday: Warmup continues, but we’ll turn quite windy as a result with returning rain/snow chances. Highs near 40. 7-Day Forecast: Colder air sinks back in Thursday, and then we’ll watch how this weekend’s pattern evolves. There is potential for a stronger and larger system somewhere in the eastern U.S. As of now, the trends are for more of a southern track with the brunt of the impact out of central Indiana. A potentially very strong high pressure system will slide in from the north as well, which will cause our highs to possibly fall back into the teens. ...read more read less
