Showers and even a few unusual December thunderstorms will mark Indiana's transition from near-record warmth to more fitting early-December chill.
Temperatures Monday were on track to top 70 degrees, not only in Indianapolis, but over the southern two-thirds of the Hoosier State.
The warmth will prime a cold front to trigger some rain, beginning at night over the west and north. Showers and any thunderstorms will shift to southern and eastern Indiana before ending on Tuesday.
While Tuesday's cold front will shave about 10 degrees off Tuesday's daytime readings, the day will still be significantly mild, and highs will be about 15 degrees above normal.
Wednesday, further cooling will bring highs nearly in line with normal for the date, which would be 42 degrees in Indianapolis.
