Recent Major Storm Days in Indiana

By StormAuditor Editorial Team · Published 2026-07-20 · Updated 2026-08-11

Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.

Damage-threshold ranges in this article are general guidance synthesized from industry and federal research — IBHS building-performance research, NWS severe criteria, and product standards such as UL 2218 (hail impact resistance) and ASTM D3161/D7158 (shingle wind ratings). Actual performance depends on product rating, age, installation quality, exposure, and impact characteristics — thresholds describe when damage becomes possible, not when it occurs.

Indiana frequently experiences severe weather, and understanding past storm events is crucial for homeowners, contractors, and insurance professionals. StormAuditor provides historical weather insights for significant storm days across the state.

Recent Major Storm Days and Historical Weather in Indiana

Indiana sits in the heart of the Midwest. Severe weather is no stranger here. The state sees a range of powerful storms every year. These include widespread damaging wind events and hailstorms that can cause major property damage. Knowing the history of these events is key. It supports accurate date-of-loss research and property assessments.

What Constitutes a Major Storm Day in Indiana?

For historical weather research, a "major storm day" in Indiana often involves widespread reports of severe conditions. The National Weather Service (NWS) defines severe as:

  • Hail 1.00 inch (quarter size) or larger,
  • Wind gusts of 58 mph (50 kt) or greater, or
  • A tornado.

"Significant severe" events include hail 2.00 inches (hen egg) or larger, wind gusts of 75 mph or greater, or EF2+ tornadoes.

These severe weather events can cause major property damage. For example, asphalt shingles typically begin to show functional damage from hail impacts around 1.00–1.25 inches. Wind gusts above 70 mph are often considered damaging. Widespread shingle blow-off becomes common above 75–85 mph for older 3-tab shingles. For newer architectural shingles, it takes gusts greater than 90–100 mph. StormAuditor combines data from multiple sources to help map these historical storm impacts.

How StormAuditor Measures Past Weather Events in Indiana

StormAuditor uses a strong method to give detailed historical weather insights for Indiana properties. For wind events, our SAWE-2 (Storm Auditor Wind Estimate) method builds a station-consistent background wind field. It blends data from HRRR and daily peak gusts. We then refine it with a two-pass objective analysis. That analysis uses ASOS/AWOS measured gusts and NWS Local Storm Reports (LSRs) with measured wind qualifiers. This approach helps estimate wind speeds at specific locations.

For hail events, StormAuditor's SAHE-2 (Storm Auditor Hail Estimate v2) mainly uses Maximum Estimated Size of Hail (MESH) data from MRMS radar products. This gives highly detailed hail swaths with per-pixel size estimates for areas that cross a property. Human-observed SPC storm reports and NWS severe thunderstorm warnings back these radar estimates. Remember: "at location" data means the property falls within the warning polygon or hail swath (with a 0.25-mile buffer).

How to Research a Date of Loss in Indiana

Need to check weather conditions for a specific date at an Indiana address? StormAuditor offers powerful tools:

  • Property-Level Reports: Use our /address-lookup tool. It gives a detailed historical weather report for any address. The report covers historical wind and hail data plus NOAA warning information.
  • Date-of-Loss Research: For deeper investigations, use our /date-of-loss-weather-research workflow. It guides you through compiling historical weather evidence.
  • General Weather on a Date: To see wider weather patterns for a specific date across Indiana, visit our /weather-on-this-date page.

These tools give you the data to understand the severe weather context for your date of loss.

Practical Guidance for Indiana Residents and Professionals

Understanding historical storm events like these is vital. For homeowners, this knowledge helps put property damage in context. It also helps document claims. For contractors and adjusters, accurate historical weather data is the base for assessing damage cause and scope. Attorneys can use this information to build strong cases on property claims.

Remember, StormAuditor provides detailed weather estimates. These do not replace professional on-site inspections. Our data helps establish the likelihood of severe weather at a specific place and time. It assists qualified inspectors and engineers in their damage assessments.

Limitations

StormAuditor provides best-in-class historical weather estimates. Even so, some limits apply. Radar-derived hail estimates (MESH) can sometimes under-estimate wet hail. They can also over-estimate in very high reflectivity cores. Ground-based weather stations are crucial but sit miles apart. They can miss localized microbursts. Actual peak gusts between stations might exceed reported values. Also, properties inside a warning polygon were under a warning for severe weather. They did not necessarily experience the maximum reported conditions. StormAuditor provides objective data for putting events in context. We do not offer legal, insurance, or engineering advice. We do not claim to prove damage causation. For more on our methods and limits, visit our /methodology/wind and /methodology/hail pages.

FAQ

When was the last major hail storm in Indiana?

Recent data shows severe weather, including damaging wind events, as recently as July 2026 in various Indiana counties. For specific hail events at your location, use the StormAuditor /address-lookup tool.

How do I find storm history for my Indiana address?

Enter any Indiana address into StormAuditor's /address-lookup tool. You will get a detailed report of historical wind, hail, and warning data for that specific location.

What size hail causes damage to roofs in Indiana?

Asphalt shingles typically begin to show functional damage from hail impacts around 1.00 to 1.25 inches in diameter (quarter to half-dollar size). Softer or older shingles may show bruising from smaller impacts. Window and skylight breakage can become common with hail 1.75 inches (golf ball) or larger.

What wind speeds are considered damaging for homes in Indiana?

Wind gusts of 58 mph (50 knots) or higher are considered severe by the NWS. Wind speeds above 70 mph can cause widespread damage. Shingle uplift and blow-off become common for older roofing at 75-85 mph. For newer architectural shingles, it takes 90-100 mph.

Can StormAuditor help with insurance claims in Indiana?

StormAuditor provides objective, historical weather data. It puts conditions on a specific date of loss in context. This helps homeowners, contractors, adjusters, and attorneys with their assessments. We don't offer legal or insurance advice. Still, our data can be a valuable tool for understanding the weather events that occurred.
