...COOLER TEMPERATURES AND DRIER WEATHER ON THE WAY FOR MUCH OF  
THE EASTERN U.S...  
   
..HOT AND DRY WEATHER TO CONTINUE FOR THE DESERT SOUTHWEST
 
 
...DEVELOPING MONSOON PATTERN WILL BRING SHOWERS AND THUNDERSTORMS  
TO THE FOUR CORNERS REGION...  
   
..DEVELOPING TROPICAL SYSTEM OFFSHORE THE CAROLINAS
 
 
SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS ARE EXPECTED  
ACROSS THE SOUTH, SOUTHEAST AND MID-ATLANTIC REGIONS AS A COLD  
FRONT DROPS SOUTH AND THEN STALLS THIS WEEKEND. LOCALLY HEAVY  
RAINFALL AND AT LEAST AN ISOLATED THREAT OF FLASH FLOODING WILL BE  
POSSIBLE. BEHIND THE FRONT, COOL HIGH PRESSURE WILL SPREAD ACROSS  
THE GREAT LAKES, OHIO VALLEY AND THE NORTHEAST WHICH WILL ALSO  
FILTER SOUTH DOWN ACROSS THE MID-ATLANTIC REGION. MUCH DRIER  
CONDITIONS WILL BE NOTED AND TEMPERATURES WILL BE NEAR TO SLIGHTLY  
BELOW NORMAL.  
 
OFFSHORE OF THE CAROLINAS TROPICAL DEPRESSION THREE IS FORECAST  
FROM THE NATIONAL HURRICANE CENTER TO STRENGTHEN TO A TROPICAL  
STORM BY SATURDAY EVENING, YET ITS MOVEMENT LOOKS TO BE VERY SLOW  
AT THIS TIME. THIS WILL ALSO KEEP THE CHANCES FOR RAIN ACROSS THE  
MID-ATLANTIC INTO EARLY NEXT WEEK. PLEASE REFER TO THE NHC WEBPAGE  
FOR SPECIFIC INFORMATION ABOUT THE TROPICAL SYSTEM.  
 
MEANWHILE, A COLD FRONT WILL BE EJECTING OUT ACROSS THE NORTHERN  
HIGH PLAINS AND GRADUALLY THE UPPER MIDWEST THROUGH THE WEEKEND,  
WHICH WILL ALLOW FOR A RESURGENCE OF HOT TEMPERATURES ACROSS THESE  
AREAS. IN FACT, TEMPERATURES WILL LOCALLY BE APPROACHING 100  
DEGREES ON SATURDAY ACROSS THE DAKOTAS. THE FRONT AS IT ARRIVES  
THOUGH WILL BE A FOCUS FOR AT LEAST SCATTERED SHOWERS AND  
THUNDERSTORMS. SOME OF THE HEAVIEST RAINFALL WITH THE FRONT SHOULD  
TEND TO FOCUS OVER AREAS OF EASTERN NORTH DAKOTA AND NORTHERN  
MINNESOTA AND SOME LOCALIZED FLASH FLOODING WILL BE POSSIBLE HERE.  
 
HOT AND DRY CONDITIONS WILL PERSIST ACROSS MUCH OF THE DESERT  
SOUTHWEST AS THE MID AND UPPER-LEVEL RIDGING REMAINS IN PLACE.  
MANY LOCATIONS WILL HAVE AFTERNOON HIGHS OF 110 TO 115 DEGREES,  
WHICH COULD EASILY SET OR BREAK DAILY RECORDS. A DEVELOPING  
MONSOONAL PATTERN WILL BRING AN INCREASE OF SHOWERS AND  
THUNDERSTORMS TO THE FOUR CORNERS REGION THROUGH THE WEEKEND AND  
INTO EARLY NEXT WEEK.
