   DAY 2 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1152 AM CDT THU MAY 23 2013
   
   VALID 241200Z - 251200Z
   
   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE CNTRL HIGH PLAINS...
   
   ...CENTRAL/SOUTHERN PLAINS...
   
   MEAN UPPER RIDGE WILL REMAIN ANCHORED OVER THE MIDDLE OF THE CONUS
   THROUGH THE DAY2 PERIOD.  WHILE EMBEDDED SHORT-WAVES WILL ROTATE
   INTO THE BASE OF THE WRN U.S. TROUGH AND EJECT NEWD...IT APPEARS THE
   PRIMARY INFLUENCE OF THESE FEATURES WILL BE NOTED ACROSS THE GREAT
   BASIN INTO THE NRN ROCKIES...WELL WEST OF THE HIGH PLAINS.  EVEN
   SO...FAVORABLE LEE TROUGHING SHOULD ENCOURAGE A MOISTENING BOUNDARY
   LAYER ACROSS THE HIGH PLAINS AND SFC DEW POINTS IN THE 50S SHOULD
   EASILY BE TRANSPORTED ACROSS WRN KS INTO THE NEB PANHANDLE.
   
   STRONG BOUNDARY LAYER HEATING IS ANTICIPATED ACROSS SERN WY/ERN CO
   FRIDAY AFTERNOON AND THIS WILL PROVE INSTRUMENTAL IN CONVECTIVE
   DEVELOPMENT NEAR/JUST EAST OF PALMER DIVIDE SFC LOW THAT IS EXPECTED
   TO MIGRATE INTO NERN CO DURING THE EVENING.  FAVORABLE UPSLOPE FLOW
   AND SFC HEATING SHOULD PROVE ADEQUATE IN AT LEAST ISOLATED
   SUPERCELLS BENEATH MODEST SWLY FLOW ALOFT...ON THE ORDER OF 35KT AT
   500MB.  LARGE HAIL IS EXPECTED WITH THESE STORMS AND IF DEW POINTS
   CAN RISE INTO THE UPPER 50S CLOUD BASES SHOULD BE ADEQUATELY LOW AND
   SUPPORTIVE OF TORNADOES.
   
   FARTHER SOUTH...MUCH WEAKER FLOW IS EXPECTED ACROSS THE SRN PLAINS
   WHERE SFC-6KM DEEP LAYER SHEAR SHOULD BE ON THE ORDER OF 15KT.  IT/S
   NOT ENTIRELY CLEAR HOW CONVECTION WILL EVOLVE ACROSS THIS REGION BUT
   SFC HEATING BENEATH MID LEVEL WEAKNESS/COOLER MID LEVEL TEMPERATURES
   FAVOR A FEW STRONG STORMS...ESPECIALLY GIVEN THE HIGHER DEW
   POINTS/INSTABILITY.  HAIL IS THE PRIMARY THREAT WITH THE MORE ROBUST
   ACTIVITY.
   
   
   ...ELSEWHERE...
   
   A FEW TSTMS MAY DEVELOP ACROSS THE CNTRL/SRN PENINSULA DURING THE
   HEAT OF THE DAY AND ALONG NW-SE ORIENTED CONFLUENCE ZONE ACROSS SERN
   TX INTO SRN LA.  CONVECTION ACROSS BOTH REGIONS SHOULD EVOLVE WITHIN
   AN ENVIRONMENT SUPPORTIVE OF GUSTY WINDS OR SMALL HAIL BUT LITTLE
   CHANCE FOR MEANINGFUL ORGANIZATION.
