...LOWER MS VALLEY...

SWLY LOW LEVEL JET WILL INTENSIFY IN ASSOCIATION WITH RIGHT ENTRANCE
REGION OF UPPER JET DEVELOPING OVER THE OH VALLEY. THE LOW LEVEL JET
WILL TRANSPORT PARTIALLY MODIFIED GULF MOISTURE ABOVE MODIFYING
ARCTIC AIR AND CONTRIBUTE TO SOME DESTABILIZATION. HOWEVER...MODEST
MID LEVEL LAPSE RATES AND MOISTURE RETURN WILL RESULT IN ONLY WEAK
INSTABILITY. ISENTROPIC LIFT AND WARM ADVECTION ASSOCIATED WITH THE
LOW LEVEL JET IS ALREADY CONTRIBUTING TO SHALLOW ELEVATED CONVECTION
FROM SERN OK INTO THE LOWER MS VALLEY. HOWEVER...IT APPEARS THAT
INSTABILITY WILL REMAIN INSUFFICIENT TO SUPPORT MORE THAN AN
ISOLATED LIGHTING STRIKE OR TWO.
