Indianapolis, Indiana – A shift toward colder-than-normal weather during the Jan 20–24 period is increasing concern for winter weather across central and southern Indiana, particularly if precipitation moves through while colder air is established. While significant snow is not guaranteed, the evolving pattern raises the risk for snow or ice, especially during overnight and early morning hours.
According to the National Weather Service Climate Prediction Center, Indiana carries a 50–60% probability of below-normal temperatures during the January 20–24 window. Precipitation probabilities remain above normal at 40–50%, a combination that supports wintry precipitation potential when temperatures dip toward or below freezing.
In Indianapolis and much of central Indiana, daytime temperatures may hover near seasonal averages but are expected to fall below freezing at night. That setup could allow rain to transition to snow or a wintry mix if systems pass through during colder periods. Southern Indiana, including Bloomington, Columbus, Seymour, and areas along the Ohio River, may also see snow or ice if colder air deepens behind passing systems. Farther south, precipitation type may vary at times, but slick conditions remain possible if temperatures cool quickly.
Major travel corridors such as I-65, I-69, I-70, I-74, and State Road 37 could become slick during wintry precipitation, particularly overnight and during the morning commute. Cold pavement temperatures may allow snow or ice to linger on untreated roads, bridges, and overpasses, increasing the risk for hazardous travel.
Residents are encouraged to prepare ahead of the Jan 20–24 window by monitoring updated weather information, checking heating systems, and ensuring vehicles are winter-ready. While significant snow is not guaranteed, the evolving pattern supports the possibility of at least one impactful winter weather event across central and southern Indiana.
This cooler pattern is expected to persist through late week, and additional winter weather advisories or alerts may be issued as confidence in timing and impacts increases.
