Issued a severe thunderstorm warning strictly off of explosive CTC at 2315 UTC (previous post), with very little showing up on radar at the time.  As would be expected, through the following 15-20 minutes, the storm exploded, with MRMS MESH spiking up to 1″ by 2334 UTC, and a quarter size hail report by 2336 UTC.  This gave us 21 minutes of lead time from the initial warning issuance off of CTC.  Would have likely issued the warning based on traditional base products by 2325 UTC, 10 minutes after the CTC-based issuance.
