...SEVERE WEATHER AND LOCALLY HEAVY RAIN FORECAST FOR NORTH DAKOTA  
AND MINNESOTA...  
 
...SHOWERS AND THUNDERSTORMS EXPECTED FOR THE SOUTHERN TIER OF THE  
COUNTRY...  
 
...HOT AND DRY WEATHER CONTINUES IN THE WEST, THOUGH MODERATING  
SOMEWHAT...  
 
A COLD FRONT SLOWLY MOVING THROUGH THE NORTHERN PLAINS WILL  
PROVIDE A FOCUS FOR THUNDERSTORM DEVELOPMENT ON SATURDAY NIGHT AND  
SUNDAY IN THE NORTHERN PLAINS TO THE UPPER MIDWEST. THE STORM  
PREDICTION CENTER HAS SLIGHT RISKS OF SEVERE WEATHER IN PLACE FOR  
NORTH DAKOTA AND NORTHERN MINNESOTA THROUGH SATURDAY NIGHT, AND  
FOR PARTS OF MINNESOTA ON SUNDAY. LOCALLY HEAVY RAINFALL IS ALSO  
POSSIBLE, BUT WIDESPREAD FLASH FLOODING IS NOT EXPECTED.  
 
FRONTS IN THE LOWER MISSISSIPPI VALLEY TO THE SOUTHEAST WILL  
LINGER THROUGH THE BEGINNING OF THE WEEK, LEADING TO CONTINUED  
SHOWERS AND THUNDERSTORMS THERE. PLENTY OF MOISTURE ALSO MOVES  
INTO TEXAS, AND THESE REGIONS WILL SEE RAIN THAT IS MOST  
WIDESPREAD ON SUNDAY. LOCALLY HEAVY RAIN IS EXPECTED, WITH SOME  
FLASH FLOODING POSSIBLE AS SOME STORMS PRODUCE LOTS OF RAIN IN A  
SHORT PERIOD OF TIME. 1-2 INCHES OF RAIN IS POSSIBLE ACROSS PARTS  
OF TEXAS AND LOUISIANA, WITH LOCALLY HIGHER AMOUNTS.  
 
THE SOUTHWEST AND INTO THE FOUR CORNERS REGION WILL SEE SOME  
RELIEF FROM THE HEAT AS A MONSOON PATTERN DEVELOPS THERE, LEADING  
TO INCREASED RAIN SHOWERS AND THUNDERSTORMS FOR SUNDAY AND MONDAY.  
A FEW STORMS COULD BE SEVERE IN THE SOUTHWEST ON SUNDAY, ACCORDING  
TO THE STORM PREDICTION CENTER.  
 
AFTER SEVERAL RECORD-BREAKING HOT DAYS IN CALIFORNIA AND THE  
SOUTHWEST, TEMPERATURES WILL STILL BE WARMER THAN AVERAGE FOR THE  
BEGINNING OF THE WEEK, BUT NOT QUITE AS SWELTERING. SOME EXCESSIVE  
HEAT WARNINGS WILL REMAIN IN EFFECT ON SUNDAY IN NEVADA AND  
CALIFORNIA, BUT WILL NOT BE AS WIDESPREAD. WARMER THAN AVERAGE  
TEMPERATURES ARE FORECAST FOR THE INTERMOUNTAIN WEST, WITH THE  
NORTHERN GREAT BASIN SEEING HIGH TEMPERATURES 10 TO 15 DEGREES  
ABOVE AVERAGE BY MONDAY. ON THE OTHER HAND, THE SOUTHERN PLAINS TO  
SOUTHEAST WILL BE SLIGHTLY COOLER THAN AVERAGE, WITH SHOWERS,  
THUNDERSTORMS, AND CLOUDS. IN FACT, WITH THE NORTHERN TIER OF THE  
COUNTRY WARMER THAN NORMAL AND THE SOUTHERN TIER SLIGHTLY COOLER  
THAN NORMAL, HIGH TEMPERATURES WILL BE APPROXIMATELY 90 DEGREES ON  
MONDAY ALMOST EVERYWHERE, OTHER THAN THE COOLER PACIFIC NORTHWEST  
AND WARMER SOUTHWEST, AS WELL AS HIGHER ELEVATIONS.  
 
TROPICAL DEPRESSION THREE OFF THE COAST OF NORTH CAROLINA IS  
EXPECTED TO STRENGTHEN INTO A TROPICAL STORM BY SUNDAY MORNING,  
BUT IS NOT EXPECTED TO MAKE LANDFALL IN THE U.S., AS A STATIONARY  
FRONT WILL KEEP IT EAST OF THE COAST. IT WILL LINGER OFFSHORE FOR  
THE NEXT COUPLE OF DAYS THOUGH, SO SHOWERS AND THUNDERSTORMS ARE  
FORECAST FOR THE OUTER BANKS IN PARTICULAR, WHICH COULD SEE UP TO  
AN INCH OF RAIN THROUGH MONDAY. HIGH SURF AND RIP CURRENTS ARE  
LIKELY THERE AS WELL. PLEASE SEE THE NATIONAL HURRICANE CENTER FOR  
MORE INFORMATION ABOUT THIS SYSTEM.
