Trends are being monitored for an additional severe weatherwatch downstream.DISCUSSION...A large and sustained cluster of storms continues toevolve, with strongest convection along a corridor arcing fromsoutheast of College Station, TX into the Fort Polk, LA vicinity.This appears to be near the northern periphery of warmer and morestrongly capping mid-level air associated with subtropical ridging.It is being supported by lift associated with lower/mid troposphericwarm advection, beneath a strongly divergent upper flow fieldassociated with coupled speed maxima along the subtropical jet.The forcing, and associated convection are forecast to continuedeveloping fairly rapidly east-northeastward into the lowerMississippi Valley through 00-02Z.Southerly 850 mb flow on the order of 40+ kt appears to besupporting moistening inflow, with lifted parcels characterized byat least modest CAPE on the order of 500-1000 J/kg. This likelywill continue, but the the motion of convection may still beoutpacing the advection of more substantive boundary-layerinstability, with leading stratiform precipitation tending tomaintain stable to neutral near-surface lapse rates northeast ofactivity.Still, there has been a strong signal within model output that anevolving mesoscale convective vortex will be accompanied byintensifying wind fields to 50-70+ kt within the 850-700 mb layeracross and east of the lower Mississippi Valley this evening. Asthis occurs, the risk for potentially damaging wind gusts seemslikely to increase somewhere across central Louisiana intosouthwestern Mississippi. A risk for tornadoes may also develop,but this will largely hinge on further boundary-layer moistening anddestabilization of near-surface lapse rates...Kerr.. 04/23/2021...Please see www.spc.noaa.gov for graphic product...ATTN...WFO...JAN...LIX...LCH...SHV...HGX...LAT...LON 31899450 32149338 32039205 31549027 30289163 3068932130769383 30449548 30689597 31789509 31899450BULLETIN - IMMEDIATE BROADCAST REQUESTEDSEVERE THUNDERSTORM WARNINGNATIONAL WEATHER SERVICE NORMAN OK613 PM CDT FRI APR 23 2021THE NATIONAL WEATHER SERVICE IN NORMAN HAS ISSUED A* SEVERE THUNDERSTORM WARNING FOR...
