2245 UTC:  Switch to NC domain.  Severe storms and warnings already in progress.  Substantial convection in KS/MO/NE has not initiated.

2229 UTC: 1″ hail Eastern Johnston NC.  Biased corrected MESH underestimated by 0.5″ and MESH 0.25.

2307 UTC:  30 min rotation tracks coincident with hook echo from KMHX.  0-2 km AzShear ~0.11.  Concern that 0-2km AzShear may have too much contribution from higher level rotation.  Thought of having a very low-level AzShear product in multiradar mode.

WDSS-II Color scale on MR EchoTop at 50 did not agree with cursor-sampled  values.

2320 UTC: NE Craven County storm intensifying based on MESH trends.

MR/MS trend products potentially useful for mesoanalyst forecaster position.

2338 UTC: NE Craven County storm — storm split observed in MESH track

2345 UTC: Southern Suffolk County VA — bowing segments. MARC signature noted in vertical velocity cross section @ 2322 UTC.  Damage reported 2330

0000 UTC: Northen Craven County NC — funnel cloud report in left mover

Since we were in discussion mode, started montoring with live NWS warnings turned on.

It might be useful in some type of IOP exercise to have a WDSS driver to pull up the products faster.  Group discussion mode/thinking out loud not a bad technique.

Possible useful visualization technique:  spatial map of MR/MS trends tendency.

At 0045 UTC:  Group IOP ended. and a final CASA archive case was played back for the rest of the shift.
