DISCUSSION
 
 
SKIES ARE CLEAR ACROSS MUCH OF THE FORECAST AREA EARLY THIS  
MORNING WITH TEMPERATURES RANGING FROM THE UPPER 50S TO AROUND 70  
DEGREES. HIGH PRESSURE IS CENTERED NEAR ST. LOUIS AT THIS TIME.  
THE HIGH WILL MOVE SLOWLY NORTHEAST TODAY. THIS WILL RESULT IN DRY  
WEATHER. TEMPERATURES WILL BE SIMILAR TO YESTERDAY WITH HIGHS IN  
THE LOW TO MID 80S.  
 
THE SURFACE HIGH WILL REMAIN OVER THE GREAT LAKES REGION ON FRIDAY  
AND SATURDAY WHICH WILL RESULT IN CONTINUED DRY WEATHER WITH BELOW  
NORMAL TEMPERATURES FOR BOTH DAYS.  
 
THE FORECAST FROM SUNDAY THROUGH WEDNESDAY REMAIN HIGHLY DEPENDENT  
ON WHAT HAPPENS WITH TROPICAL STORM HARVEY. THE LATEST FORECAST  
SHOWS HARVEY REACHING THE SOUTH TEXAS COAST SOMETIME SATURDAY AND  
THEN REMAINING OVER SOUTH TEXAS THROUGH THE REMAINDER OF THE  
WEEKEND BEFORE STARTING TO MOVE NORTHEAST. THIS SCENARIO WOULD  
DELAY THE START OF RAIN MOVING INTO THE FORECAST AREA TO AT LEAST  
SUNDAY.  
 
AS THE REMNANTS OF HARVEY EDGE CLOSER TO THE REGION, THE CHANCE OF  
RAIN WILL INCREASE BETWEEN MONDAY AND WEDNESDAY. MUCH UNCERTAINTY  
REMAIN REGARDING THE EXACT TRACK OF HARVEY ESPECIALLY AFTER IT HAS  
MADE LANDFALL WHICH COULD DRASTICALLY AFFECT HOW MUCH RAIN DOES  
FALL IN THE REGION. THERE STILL REMAIN THE POSSIBILITY OF EXTREME  
RAINFALL AMOUNTS BY THE END OF THE FORECAST PERIOD. THIS WILL BE  
MONITORED CLOSELY AS HARVEY GETS CLOSER TO THE U.S.

AVIATION
 
 
06Z TAF CYCLE  
 
VFR CONDITIONS WILL PERSIST THE ENTIRE PERIOD WITH SURFACE HIGH  
PRESSURE DOMINATING. THE ONLY EXCEPTION TO THIS COULD BE KMKL  
OVERNIGHT WITH SOME FOG DEVELOPMENT. WINDS WILL GENERALLY BE FROM  
THE NE LESS THAN 10 KTS THROUGHOUT, WITH SKIES REMAINING MOSTLY  
CLEAR.
