...TROPICAL STORM GORDON HAS MADE LANDFALL AND WILL CONTINUE TO  
TRACK INLAND BRINGING HEAVY RAIN THREATS AND FLASH FLOODING TO THE  
LOWER MISSISSIPPI VALLEY...  
 
...EXCESSIVE RAINFALL AND FLASH FLOODING LIKELY ACROSS THE CENTRAL  
PLAINS, MIDDLE AND UPPER MISSISSIPPI VALLEYS, AND INTO THE UPPER  
GREAT LAKES...  
   
..EXCESSIVE HEAT WILL BE FELT ACROSS THE NORTHEASTERN U.S.
 
 
TROPICAL STORM GORDON MADE LANDFALL LATE TUESDAY EVENING NEAR THE  
ALABAMA AND MISSISSIPPI BORDER AND IS FORECAST TO WEAKEN AS IT  
HOOKS NORTH-NORTHEAST THROUGH ARKANSAS, MISSOURI AND THROUGH THE  
UPPER MIDWEST/ GREAT LAKES REGION BY THE END OF THE WEEK. A SWATH  
OF 2 TO 5 INCHES, WITH LOCALIZED HIGHER AMOUNTS, IS FORECAST FROM  
MISSISSIPPI TO ILLINOIS IN A BOOMERANG PATTERN. A VAST AREA WILL  
HAVE ELEVATED FLOODING CONCERNS OVER THE NEXT FEW DAYS. WPC HAS  
PORTIONS OF THE LOWER MISSISSIPPI VALLEY AND MIDWEST IN A MODERATE  
RISK FOR EXCESSIVE RAINFALL.  
 
MULTIPLE ROUNDS OF RAIN AND THUNDERSTORMS WILL PERSIST ACROSS  
PARTS OF THE CENTRAL PLAINS AND MID/UPPER MISSISSIPPI VALLEY,  
WHICH WILL MAINTAIN AND ELEVATED THREAT FOR CONTINUED FLOODING. A  
STRONG FRONTAL SYSTEM WILL PUSH THROUGH THE NORTHERN PLAINS AND  
UPPER MISSISSIPPI VALLEY TODAY AND PROVIDE A FOCUS FOR HEAVY RAIN  
ACROSS THE MID AND UPPER MISSISSIPPI VALLEY AND INTO THE UPPER  
GREAT LAKES REGION. NUMEROUS AREAS WITHIN THIS REGION ARE ALREADY  
EXPERIENCING SATURATED SOILS AND ONGOING FLOODING, SO ANY FURTHER  
RAINFALL WILL ONLY FURTHER EXACERBATE THE SITUATION. LARGE AREAS  
OF THE CENTRAL PLAINS, MIDDLE AND UPPER MISSISSIPPI VALLEY AND THE  
UPPER GREAT LAKES ARE CURRENTLY UNDER FLASH FLOOD WATCHES AND  
WARNINGS. EXPECT THESE THREATS TO MOVE SLIGHTLY SOUTHWARD AND  
EASTWARD WITH THE FRONTAL SYSTEM OVER THE COMING DAYS.  
 
AHEAD OF THIS APPROACHING COLD, HOT AND MUGGY CONDITIONS WILL  
CONTINUE ACROSS MUCH OF THE EASTERN STATES. HEAT ADVISORIES ARE IN  
EFFECT FOR PARTS OF THE NORTHEAST AND COASTAL MID-ATLANTIC.
