Day 1 Convective Outlook NWS Storm Prediction Center Norman OK
0757 PM CDT Fri May 22 2020 Valid 230100Z - 231200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ALONG THE RED
RIVER CORRIDOR OF TEXAS AND OKLAHOMA... ...SUMMARY...
The primary threat for severe storms will continue overnight from
north Texas, across southern Oklahoma, into central Arkansas. ...01z Update... Early-day MCS that spread across OK/MO/AR produced an outflow
boundary that has mostly dissipated but remains highly influential.
Low-level flow remains east-southeasterly along a corridor from the
Red River into central AR. Deep convection is expanding in areal
coverage within this corridor where air mass is quite moist and
buoyant. 00z soundings from OUN/FWD exhibit MLCAPE around 3100 J/kg
with weak inhibition near 750mb. While deep-layer flow is a bit
marginal for supercells at FWD, OUN sounding is supportive of
supercells along with some threat for tornadoes. Given the OUN
sounding, and recent convective development, have adjusted higher
severe probabilities north to include much of southern OK. An
upward-evolving complex of storms should propagate along the Red
River well into the overnight hours. ..Darrow.. 05/23/2020
