VALID 241914Z - 242015Z

STORMS ARE EXPECTED TO CONTINUE DEVELOPING SEWD THROUGH ERN OK INTO
NRN AND CNTRL AR NEXT FEW HOURS. LARGE HAIL AND ISOLATED DAMAGING
WIND WILL BE THE PRIMARY THREATS. A NEW WW WILL LIKELY BE NEEDED FOR
PORTIONS OF ERN OK INTO WRN AR WITHIN THE NEXT HOUR OR SO.

THIS AFTERNOON A LINE OF SEVERE STORMS FROM NERN OK INTO NWRN AR
CONTINUES SEWD. THE LINE HAS TRANSITIONED TO A FORWARD PROPAGATING
MCS...AND THE ATMOSPHERE DOWNSTREAM ACROSS NWRN AR AND ERN OK HAS
BECOME MODERATELY UNSTABLE WITH MLCAPE FROM 2000 TO 2500 J/KG. LOW
LEVEL CONVERGENCE AND LIFT ALONG THE GUST FRONT ALONG WITH WEAKENING
CONVECTIVE INHIBITION SHOULD SUSTAIN THE MCS THROUGH ERN OK NRN AR
NEXT FEW HOURS. STEEP MID LEVEL LAPSE RATES...STRONG INSTABILITY AND
SUFFICIENT CLOUD LAYER SHEAR FOR EMBEDDED SUPERCELLS WILL CONTINUE
TO SUPPORT A THREAT FOR LARGE HAIL. ISOLATED DAMAGING WIND GUSTS MAY
ALSO ACCOMPANY THE STRONGER STORMS.
