MD 1027 CONCERNING SEVERE THUNDERSTORM WATCH 285… FOR SOUTHEAST OKLAHOMA…ARKLATEX REGION
Mesoscale Discussion 1027 NWS Storm Prediction Center Norman OK 1010 PM CDT Tue Jun 13 2023 Areas affected...Southeast Oklahoma...Arklatex Region Concerning...Severe Thunderstorm Watch 285... Valid 140310Z - 140515Z The severe weather threat for Severe Thunderstorm Watch 285 continues. SUMMARY...Strong/severe convection will focus along a corridor from southeast Oklahoma into the Arklatex region. DISCUSSION...Low-level warm advection continues to aid convective regeneration across the Arklatex as 1km AGL wind near 30kt is focused into this region, per SHV VAD profile. Over the last hour or so, numerous elevated showers have developed across southeast OK, likely a sign of increasing warm advection immediately ahead of approaching short-wave trough. Latest thinking is convection will continue to develop within a strongly sheared, and steep lapse rate environment such that some severe risk will likely continue beyond watch expiration. 00z soundings from SHV, FWD, and OUN all exhibit thermodynamic profiles favorable for robust updrafts capable of generating hail. ..Darrow.. 06/14/2023 ...Please see www.spc.noaa.gov for graphic product...
