MD 1580 CONCERNING TORNADO WATCH 414… FOR PART OF CENTRAL AND EASTERN TX
Mesoscale Discussion 1580 NWS Storm Prediction Center Norman OK 0741 PM CDT Sat Oct 13 2018 Areas affected...Part of central and eastern TX Concerning...Tornado Watch 414... Valid 140041Z - 140145Z The severe weather threat for Tornado Watch 414 continues. SUMMARY...Local extension (both spatial and temporal) may be needed for the southwest part of WW 414 and extending southward several counties, as a severe-weather threat persists beyond 01Z, including the tornado potential. DISCUSSION...Mosaic radar imagery showed storms continuing to develop within the the southwest flank of a central and northeast TX MCS, while GOES-16 IR imagery indicated ongoing cloud-top cooling across this same area of the MCS. Although the main band of storms appears to be located along and near the primary southward-moving outflow boundary, radar trends also indicated new storms developing in the warm sector, immediately to the south, from Burleson to Brazos to Madison Counties. Objective analyses indicated surface-based inhibition has been increasing, given time of day across east TX into LA, though the environment in proximity to the aforementioned storms remains unstable with surface-based storms. Given the presence of a moisture-rich environment with moderate instability and effective bulk shear of 40-45 kt, embedded bowing structures and low-level rotation/tornado threat should persist until the surface-based inhibition becomes too strong. ..Peters/Guyer.. 10/14/2018 ...Please see www.spc.noaa.gov for graphic product...
