MESOSCALE DISCUSSION 0453
NWS STORM PREDICTION CENTER NORMAN OK
1009 AM CDT TUE APR 26 2016

AREAS AFFECTED...NRN/CNTRL OK...SERN KS

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 261509Z - 261645Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...AN ISOLATED HAIL THREAT WILL EXIST THIS MORNING ACROSS
PARTS OF NRN/CNTRL OK AND POSSIBLY INTO SERN KS. A WW IS NOT
CURRENTLY ANTICIPATED AS THIS THREAT SHOULD REMAIN LOCALIZED IN THE
SHORT-TERM...BUT TRENDS WILL BE MONITORED.

DISCUSSION...AN ISOLATED TSTM HAS DEVELOPED NE OF THE OKC METRO AREA
THIS MORNING...ALONG THE NRN PERIPHERY OF A RIBBON OF
MOISTENING/ISENTROPIC ASCENT NOTED IN WATER VAPOR IMAGERY. THIS
STORM IS LIKELY ROOTED NEAR 700 MB AT THE MOMENT...BUT WITH VERY
STEEP MIDLEVEL LAPSE RATES /NEAR 9 C/KM PER 12Z OUN SOUNDING/ A HAIL
THREAT MAY CONTINUE TO ACCOMPANY THIS STORM AND ANY ADDITIONAL TSTMS
THAT DEVELOP. HOWEVER...COVERAGE IS EXPECTED TO REMAIN ISOLATED
THROUGH THE LATE MORNING GIVEN THE RELATIVELY CONFINED AREA OF
ASCENT...AND THIS SHOULD PRECLUDE WW ISSUANCE IN THE
SHORT-TERM...BEFORE MORE WIDESPREAD TSTM/SVR POTENTIAL ACCOMPANYING
THE LARGER UPSTREAM TROUGH INCREASES LATER TODAY.
