Storms Dump Over 3 Inches of Rain and 2 Inch Hail Across Dallas Fort Worth Texas as Outflow Boundary Triggers Widespread Coverage Exceeding Forecasts
DALLAS, TX — Storms that developed across the Dallas Fort Worth metroplex after a capping inversion broke this afternoon produced far more widespread coverage and rainfall than initially forecast, with storm total accumulation radar showing 3.46 inches of rain recorded near Fort Worth, DFW Airport picking up 2.31 inches, some areas receiving over 3 inches, and the largest hail reports reaching 2 inches in diameter near Lebanon Road in The Colony.
Coverage Exceeded Expectations Significantly
Forecasters had anticipated approximately 30 percent storm coverage across North Texas heading into the afternoon, but a massive outflow boundary generated by the initial round of storms spread across the Dallas Fort Worth Metroplex and triggered additional slow moving storm development that pushed total coverage closer to 50 percent across the region.
The outflow boundary acted as a triggering mechanism for new storm initiation, extending the storm event well beyond the originally expected footprint and delivering rainfall to portions of the metroplex that may have otherwise stayed dry under the original forecast coverage scenario during the afternoon and evening hours.
Rainfall Totals Paint a Dramatic Picture
Storm total accumulation radar from KFWS Dallas shows a striking and concentrated pattern of extreme rainfall centered across the Fort Worth to Dallas corridor, with the deepest red accumulation values indicating 3.46 inches near Fort Worth and additional heavy totals extending northward toward Denton and into the Plano area where 1 to 2 inch totals were recorded.
The highly variable and localized nature of the rainfall distribution meant that while some locations received over 3 inches of rain, nearly half of North Texas saw little to no precipitation from the afternoon storm event, a characteristic pattern when outflow boundary triggered convection dominates the storm coverage distribution across a large metropolitan area.
Two Inch Hail Reported in The Colony
Beyond the significant rainfall totals, several storms within the complex produced large hail during their most intense phases, with the biggest confirmed hail reports reaching 2 inches in diameter near Lebanon Road in The Colony, a size well above the severe threshold of one inch and capable of causing serious damage to vehicles, roofing materials, and outdoor property.
Additional hail reports of half inch to one inch diameter were documented across other portions of the metroplex as individual storm cells moved through various communities during the afternoon convective period.
