South Texas Severe Storms Final Scorecard, Nov 8, 2026
South Texas severe storms (Nov 8, 2026) maps National Weather Service tornado, hail, and wind reports inside the stored search area. No tornado, hail, or wind report verified for this storm. That is the stored result. 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 the Day 1 Marginal Risk in a small part of South Texas, inside the stored search area. Corpus Christi is the tracked market in that area. The box follows the Marginal Risk outline, from the lower Texas coast inland toward Duval County. Austin, San Antonio, Victoria, Laredo, and Harlingen–Weslaco–Brownsville–McAllen sit outside it, as do Webb County and the Rio Grande Valley. The date is Sunday, November 8. Sunday's risk is strong to locally severe thunderstorms near the coast in the vicinity of Corpus Christi, with isolated damaging winds and perhaps a brief tornado. The Day 1 convective outlook valid from 12Z November 8 through 12Z November 9 is the window. Day 2 and Day 3 have no severe thunderstorm area, so this page closes after Sunday, November 8. Flood and heavy-rain reports for south Texas, including Duval County, Webb County, Corpus Christi, and the Rio Grande Valley, stay on the flash flood page.

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.
