SUMMARY...STORMS CAPABLE OF LARGE TO VERY LARGE HAIL AND SEVERE

DISCUSSION...THUNDERSTORM ACTIVITY ONGOING NEAR THE TRANS PECOS AND

THE ENVIRONMENT ACROSS THIS REGION IS CHARACTERIZED BY MLCAPE AROUND
500-1000 J/KG, STEEP LOW TO MID-LEVEL LAPSE RATES, AND DEEP LAYER
SHEAR 45-50 KTS. FURTHER DAYTIME HEATING AND MOIST ADVECTION WILL

WILL SUPPORT A MIX OF SUPERCELLS AND MULTI-CELL CLUSTERS CAPABLE OF
LARGE TO VERY LARGE HAIL (SOME 2-2.5 IN) AND SEVERE WIND. THERE IS
SOME UNCERTAINTY ON WHEN THE MOST ROBUST CONVECTION WILL DEVELOP
