MESOSCALE DISCUSSION 0767
NWS STORM PREDICTION CENTER NORMAN OK
0235 PM CDT MON MAY 25 2015

AREAS AFFECTED...SERN OK/SWRN AR/E TX

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 251935Z - 252030Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...CONTINUED EWD ADVANCE OF A WELL-ORGANIZED MCS ACROSS
CENTRAL TX AND MORE ISOLATED ROTATING STORMS EVOLVING AHEAD OF THE
LINE WILL RESULT IN AN INCREASING RISK FOR DAMAGING WINDS AND
ISOLATED TORNADOES ALONG WITH HAIL ACROSS THE MD AREA.  NEW TORNADO
WATCH WILL BE REQUIRED WITHIN THE NEXT HOUR.

DISCUSSION...LATEST RADAR LOOP SHOWS WIDESPREAD STRONG/SEVERE STORMS
ACROSS CENTRAL TX -- INCLUDING A WELL-ORGANIZED BOWING MCS AND
INCREASINGLY NUMEROUS SUPERCELLS AHEAD OF THE MAIN CONVECTIVE LINE.
THE STORMS ARE MOVING THROUGH A MOIST/MODERATELY UNSTABLE
ENVIRONMENT...AND ARE BEING AIDED BY A MID-LEVEL JET STREAM CROSSING
CENTRAL TX S OF A NWRN TX/SWRN OK VORT MAX.  WITH THE ENVIRONMENT E
OF THE CONVECTION/E OF THE ONGOING TORNADO WATCHES SUPPORTIVE OF
MAINTENANCE OF STORM INTENSITY...LIKELIHOOD FOR SEVERE STORMS TO
PERSIST/SPREAD EWD ACROSS SERN OK AND ERN TX APPEARS HIGH.  AS
SUCH...AREAS E OF THE EXISTING WATCHES -- I.E. ACROSS THE MD AREA --
WILL REQUIRE NEW WW ISSUANCE IN THE NEXT HOUR.
