MD 0396 CONCERNING SEVERE POTENTIAL…WATCH LIKELY FOR NORTHEAST TX INTO SOUTHEAST OK
Mesoscale Discussion 0396 NWS Storm Prediction Center Norman OK 0116 PM CDT Fri Mar 31 2023 Areas affected...Northeast TX into southeast OK Concerning...Severe potential...Watch likely Valid 311816Z - 311945Z Probability of Watch Issuance...80 percent SUMMARY...Storms capable of hail, damaging gusts, and a couple of tornadoes are possible this afternoon. Watch issuance is likely. DISCUSSION...Convection is gradually increasing along a cold front/effective dryline from northeast TX into southeast OK. Strong heating of a moist low-level environment has resulted in MLCAPE of 1500-2500 J/kg across the region, with effective shear of 50-70 kt more than sufficient for organized storm structures. Storm coverage across this region remains uncertain, with stronger large-scale ascent expected to remain north of the region, but a few supercells are likely to develop later this afternoon. Large hail and locally strong/damaging gusts are expected to be the primary initial threat, but low-level shear/SRH will be sufficient to support a threat of a couple tornadoes as well, even with surface winds likely remaining somewhat veered. Watch issuance is likely later this afternoon in order to cover these threats. ..Dean/Hart.. 03/31/2023 ...Please see www.spc.noaa.gov for graphic product...
