Midwest & Tornado Alley

The hail corridor is tightening too — see who's likely still writing

Florida and California get the headlines. But across Illinois, Indiana, Ohio, Missouri and Tornado Alley, severe-convective-storm risk is repricing premiums fast, with far less attention. CoverGuard puts it on every property check.

Geographic resolution
County or forecast zone for each report; totals by state
Classification
Observed and derived — report counts are observed NWS reports as NCEI published them (files dated 2026-03-23 to 2026-08-19; the latest year is still being revised); the state record's hail-corridor tier is derived from CoverGuard's own hail-corridor classification, not from NOAA
What it decides
Shows how often and how large hail has been reported across the corridor. It does not score a property.
Limitation
Counts are National Weather Service hail reports, not storms, claims or losses, and they rise where more people are watching. Texas is counted statewide, though CoverGuard treats only north Texas as corridor. A state total says nothing about any one property.
When to refresh
NCEI reissues each year’s file as reports are finalized, and the prior year is usually complete by late spring. Re-run after each new complete year, and at least every 180 days.

A third geographic narrative — beyond FL and CA

Premiums in the hail corridor are rising without the same crisis framing the coasts have had. CoverGuard shows the risk, with its sources, on every property check.

  • See severe-convective-storm (hail) exposure for any property, scored 0–100 alongside flood, fire, wind, earthquake and crime
  • Know modeled carrier availability and appetite for the state market at that risk profile
  • Frame rising premiums for clients before they bid, with sourced public data — not marketing claims
  • Works across the IL/IN/OH/MO corridor and Tornado Alley (KS/NE/OK/TX-N)
