Group 1:  Amarillo.  Tornado Warning for meso continues and severe warning for rest of storm for baseball size hail.  Vortex2 (DOW) reports brief tornado, other mobile mesonets report funnel clouds with storm. Concerned as southern storm merges into main supercell.  As storm continues to take right turn, will only maintain tornado warning for storm and let severe expire.   0-2 km azmuthal shear product tracking well with TOR warning.  Comparing to storms depicted by HRRR and NSSL/WRF from lunchtime briefing.

Group 2:  Pueblo.  Anticipated hail size growth (to quarters) based on trend reflectivity structure to issue warning; MESH hail size matched expected growth and provided forecaster confidence to SVR warning.  First issuance of tornado warning in Crowley and Kiowa counties, using primarily velocity data combined with reflectivity structure.
