SUPPORT WIDESPREAD PRECIPITATION AND EMBEDDED THUNDERSTORM CLUSTERS
BASED AOB THE 850 MB LEVEL.  THOUGH INSTABILITY AND VERTICAL SHEAR
WILL NOT BE PARTICULARLY STRONG...MID LEVEL LAPSE RATES NEAR 7 C/KM
AND MUCAPE APPROACHING 1000 J/KG COULD SUPPORT A ELEVATED FEW STORMS

BASED NEAR THE GROUND...ISOLATED DAMAGING GUSTS MAY ALSO
