MESOSCALE DISCUSSION 0982
NWS STORM PREDICTION CENTER NORMAN OK
0148 PM CDT FRI JUN 13 2014

AREAS AFFECTED...ERN NM...FAR W TX

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 

VALID 131848Z - 131945Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...TSTMS DEVELOPING OVER THE HIGH TERRAIN OF CNTRL NM AND FAR
W TX ARE EXPECTED TO PROGRESS EWD ACROSS THE HIGH PLAINS THIS
AFTERNOON. AN INCREASING THREAT FOR LARGE HAIL AND DMGG WINDS WILL
LIKELY REQUIRE WW ISSUANCE BY 20Z.

DISCUSSION...VISIBLE SATELLITE LOOPS SHOW TOWERING CU PERCOLATING
OVER THE SACRAMENTO/SANGRE DE CRISTO MTNS OF NM...AND THE DAVIS MTNS
OF W TX...WITH LIGHTNING TRENDS SLOWLY INCREASING. WIDESPREAD
STRATUS HAS BEEN OBSERVED OVER THE HIGH PLAINS THIS MORNING AND IS
LIMITING DIABATIC HEATING...BUT HAS SHOWN INDICATIONS OF ERODING
MORE RECENTLY. AS A RESULT...AT LEAST WEAK CINH IS LIKELY IN PLACE
OVER THE HIGH PLAINS...BUT THIS SHOULD QUICKLY ERODE AS TEMPERATURES
APPROACH THE 80S F. 

LATEST THINKING IS THAT CONVECTIVE TRENDS WILL CONTINUE TO INCREASE
NEAR/JUST E OF THE HIGHER TERRAIN...AND PROGRESS EWD INTO A MORE
MOIST AND DESTABILIZING AIR MASS. VERTICAL WIND PROFILES ARE
EXHIBITING LOW-LEVEL SLYS VEERING TO MODERATELY STRONG WLYS IN
MIDLEVELS...AND WILL BE SUFFICIENT FOR SUPERCELLS CAPABLE OF
PRODUCING LARGE HAIL AND DMGG WIND GUSTS. TSTMS MAY EVENTUALLY
CONGEAL INTO CLUSTERS/LINE SEGMENTS VIA STORM/OUTFLOW INTERACTIONS.
MIDLEVEL WLYS DECREASE WITH SWD EXTENT INTO FAR W TX...WHERE
COVERAGE MAY ALSO BE MORE ISOLATED...LENDING SOME UNCERTAINTY
WHETHER THIS AREA WILL NEED TO BE INCLUDED IN A WW.
