.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)
ISSUED AT 544 PM MDT THU AUG 7 2014

COMPLICATED SET OF TAFS DUE TO CLUSTER OF THUNDERSTORMS MOVING
THROUGH THE AREA AT THIS TIME AND THE MESOSCALE AFFECTS THEY WILL
CAUSE. THUNDERSTORMS WILL AFFECT KGLD FIRST THEN KMCK ABOUT A
COUPLE OF HOURS LATER. IT LOOKS LIKE AT THIS TIME THAT SOME
STRATUS AND FOG WILL OCCUR WITH THE BEST CHANCE OF MVFR CONDITIONS
EXPECTED AT KMCK.

ALSO INTERESTING SCENARIO FOR KMCK. MORE THAN ONE MODEL IS SHOWING
ANOTHER CLUSTER OF STORMS MOVING THROUGH KMCK BETWEEN 12Z AND 18Z.
SO SINCE THERE IS SOME SUPPORT CHOSE TO PUT IN A VCTS AT THAT TIME
AND REVISIT THIS ISSUE AGAIN FOR THE 06Z TAFS. AT KGLD THE NEXT
BATCH OF AFTERNOON AND EVENING THUNDERSTORMS WILL START AFFECT THE
AREA LATE IN THE DAY. SO CHOSE TO INTRODUCE VCTS AT THAT TIME.
