Our warning decision for northern Hidalgo County was mostly based on radar observations. The 50 dBZ core significantly exceeded the height of the hail growth zone and a three-body scatter spike was observed. Prob Severe increased to 86% simultaneous with our decision to warn based on the above radar signatures. This was a substantial increase from the previous prob severe value two minutes prior of only 38%. Although prob severe didn't offer much lead time, it helped to confirm our analysis that the storm was severe.
