Young County Severe Tstm – ENI cell tracking issues cont

2347 graham 8.0 degree

Severe thunderstorm warning issued for the cell above at 2350z…with close to 60 dbz at 40 kft. Warning mentioning 3 inch hail threat was issued based on predecessor cells in this region with similar characteristics.

Once again…because the ENI cell tracking was detecting this as 2 separate cells with each less than 40 strikes/min in close vicinity…no dangerous thunderstorm alert was issued. I would have missed the 1.25 inches hail report at Graham at 2357z. It was not until 00z that a singular cell reported greater than 40 flasher/min to send out a dangerous thunderstorms alert.  If these cell tracking had counted this as one storm…a dangerous thunderstorms alert would have been initiated at 2348z…which would have increased confidence in my warning at the same time.2348z ENI

The upward trend in lightning in the ENI lightning trace did increase confidence in severe though.

Also of note. The MRMS MESH in the CIMS prob severe did signal hail of 1 1/2 inches…which was pretty close to the reported hail size. The CIMS prob severe came in after that fact due to technical issues though.
