.AVIATION...
18Z TAF CYCLE
MCS MOVING ACROSS SRN MISSOURI COULD EVENTUALLY SEND OUT SOME
OUTFLOW BOUNDARIES THAT COULD MOVE INTO NORTHERN PARTS OF THE
MIDSOUTH AND KICK OFF ADDITIONAL TSRAS. ATTM IT LOOKS LIKE KJBR
STANDS THE BEST CHANCE FOR TSRAS SO WENT AHEAD AND ADDED A VCTS
THERE. THERE IS SOME THREAT AT KMEM AND KMKL BUT THE THREAT IS TOO
LOW TO ADD VCTS ATTM. OTRW EXPECT VFR CONDS AND LIGHT MAINLY SOUTH
WINDS WITH SOME LIGHT FOG POSSIBLE AT KMKL AND KTUP LATE TONIGHT.
