Arctic Blast Grips Indiana: Dangerous Cold and Snow Disrupt Daily Life Today

Indianapolis, IN – Indiana is bracing for a severe Arctic blast today, Friday, January 23, 2026, with plummeting temperatures, biting wind chills, and potential snow squalls threatening public safety and triggering widespread school closures.

The National Weather Service (NWS) has issued a Cold Weather Advisory for portions of central, east central, north central, and west central Indiana, effective from 1 AM today until 10 AM Saturday. Wind chills are expected to drop as low as 20 below zero, posing risks of frostbite in as little as 30 minutes on exposed skin and hypothermia with prolonged exposure.[2]

In Indianapolis, forecasts indicate daytime highs around 39°F dropping to 27°F overnight, with 25% chance of precipitation and light winds of 4 mph. However, the extreme wind chills combined with gusty conditions amplify the danger across the state.[2][6]

Broader state forecasts align with partly cloudy skies and moderate cold, but hazardous conditions dominate. Temperatures will hover in the low to mid-30s during the day in some areas, falling sharply overnight amid scattered snow showers.[8] Similar patterns are noted in Jeffersonville with highs near 35°F and lows around 17°F.[7]

Schools across northern Indiana, particularly in Porter, La Porte, and surrounding counties, have shifted to e-learning days due to the extreme cold and wind chills. Institutions like Bishop Noll Institute, East Porter County Schools, Michigan City Area Schools, and Valparaiso Community Schools announced virtual or asynchronous learning.[5] Community centers such as the Porter County Expo Center and Bonner Senior Center are also closed.

Residents are urged to limit outdoor time, dress in layers with hats and gloves, check on vulnerable neighbors, and avoid using generators indoors. Travel may be hazardous due to wintry mixes and squalls, especially in northern regions.[1][2]

January in Indiana typically sees average highs of 36°F and lows around 22°F, but today's anomaly underscores the intensity of this cold front.[3] Stay tuned for updates as conditions evolve.
