WATCH WILL LIKELY BE WARRANTED FOR THIS ACTIVITY. DISCUSSION...STRONG BOUNDARY LAYER HEATING ACROSS THE SRN HIGH PLAINS HAS CONTRIBUTED TO NEAR-DRY ADIABATIC LOW LEVEL LAPSE RATES WITH RESULTANT LOW LEVEL PARCELS NOW APPROACHING THEIR CONVECTIVE TEMPERATURES. LATEST VIS IMAGERY SUPPORTS THIS WITH SCATTERED CU DEVELOPING ALONG PRE-FRONTAL CONFLUENCE ZONE THAT CURRENTLY STRETCHES FROM LIPSCOMB TO DONLEY COUNTIES IN THE ERN TX PANHANDLE. THIS DEVELOPING CONVECTION WILL LIKELY DEEPEN OVER THE NEXT FEW HOURS WITH MATURATION INTO ONE OR MORE SEVERE COMPLEXES ACROSS WRN/NRN OK LATER THIS EVENING. THIS EVOLUTION IS POSSIBLE DUE TO A WEAK SHORT-WAVE TROUGH THAT IS MIGRATING INTO THIS REGION AND EXPECTED DIURNAL INCREASE IN LLJ THAT SHOULD FOCUS INTO CNTRL OK AFTER DARK. INITIAL TSTM ACTIVITY IS EXPECTED TO BE HIGH BASED WITH A THREAT FOR LARGE HAIL AND DAMAGING DOWNBURSTS...ESPECIALLY IF SUPERCELL-LIKE STRUCTURES CAN EVOLVE. HOWEVER...MOISTURE DOWNSTREAM ACROSS OK IS SUBSTANTIALLY HIGHER AND GIVEN THE SOMEWHAT STRONGER LOW LEVEL SHEAR A TORNADO OR TWO CAN NOT BE RULED OUT. REGARDLESS...VERY LARGE HAIL AND POTENTIALLY MORE WIDESPREAD DAMAGING WINDS MAY BE NOTED WITH MCS ACTIVITY THIS EVENING. ..DARROW/CARBIN.. 06/03/2012 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...
