Ohio Valley Severe Storms Final Scorecard, Nov 11, 2026

Ohio Valley severe storms (Nov 11, 2026) maps National Weather Service tornado, hail, and wind reports inside the stored search area. 66 National Weather Service local storm reports are on file for tornado, hail, and wind. Stored counts: 60 hail, 2 wind, 4 wind damage. Reports were filed at these places: 3 SE Lecta, KY; 1 SE Drakesboro, KY; Central City, KY; Bremen, KY; Belton, KY; 3 NE Mcquady, KY; 6 SE Hebbardsville, KY; Macio, KY; Rockport, IN; Dawson Springs, KY; 5 NE Reed, IN; 2 E Chandler, IN, and 26 more. The final scorecard grades the archived Day 1 severe outlook for each date against the stored local storm reports. That score stays as it was written. The damage map keeps National Weather Service tornado, hail, and wind reports for eastern Illinois, Indiana, western and central Kentucky, and middle Tennessee, inside the stored search area. Indianapolis, Louisville, Lexington, Nashville, Evansville, Bowling Green, Cincinnati, Terre Haute, Lafayette, Fort Wayne, and Champaign, Springfield, and Decatur are tracked markets in that area. Indianapolis, Louisville, Lincoln, Paducah, Nashville, Northern Indiana, and Wilmington, Ohio are the National Weather Service offices for the airports inside the area. Chicago, South Bend, the Paducah market, Dayton, Knoxville, and St. Louis sit outside it, as does Jackson, Kentucky. The date is Wednesday, November 11. Wednesday's risk is a marginal threat of isolated hail, damaging winds, and perhaps a tornado from parts of eastern Illinois into Indiana, western and central Kentucky, and middle Tennessee. Storms are expected to form over eastern Illinois around 18Z to 21Z and spread east through the afternoon and evening, then wane this evening. The Day 1 convective outlook valid from 12Z November 11 through 12Z November 12 is the window.

Final scorecard

The archived outlook for this event is not stored yet, so there is no score.

The technical details

The grade uses the Storm Prediction Center Day 1 categorical outlook issued at 1630 UTC for each event date, from the public archive GeoJSON named day1otlk_YYYYMMDD_1630_cat.lyr.geojson. Later updates at 2000 UTC and 0100 UTC are not used, and neither are the 0600 UTC or 1300 UTC issuances. One issuance keeps every date on the same product. A report counts when its time is at or after that issuance and before 12 UTC the next day, which is the valid window written on the product. A report exactly at 12 UTC is not in the window. Reports between 12 UTC and 1630 UTC are not graded, because this outlook was not valid yet. A report on the outline counts as inside. A point in more than one outline is counted once, in the higher risk: High, then Moderate, Enhanced, Slight, and Marginal. General thunder is the categorical thunder outline. It is not a Marginal, Slight, Enhanced, Moderate, or High risk, so it is not part of the inside count. The check is the outline itself. A report just outside the line counts as outside. This is not the Storm Prediction Center neighborhood that treats a nearby report as inside. The stored local storm reports are the ones already kept for this event. A day whose archive file could not be fetched has no score. A day that has been graded is not replaced on a later collect.
