RAIN AND THUNDERSTORMS ARE LIKELY IN THE CENTRAL AND SOUTHERN  
PLAINS THROUGH SUNDAY NIGHT. THE STORM PREDICTION CENTER HAS  
OUTLOOKED PARTS OF THE CENTRAL HIGH PLAINS UNDER AN ENHANCED RISK  
OF SEVERE WEATHER, WITH A SLIGHT RISK STRETCHING INTO THE SOUTHERN  
PLAINS. WITH PLENTY OF MOISTURE IN PLACE, FLASH FLOODING IS  
POSSIBLE AS WELL, AND A SLIGHT RISK OF EXCESSIVE RAINFALL IS ALSO  
IN PLACE FOR THOSE AREAS AS WELL AS FARTHER EAST INTO PARTS OF  
MISSOURI AND ILLINOIS.  
 
AN UPPER-LEVEL TROUGH OVER THE EASTERN HALF OF THE U.S., AS WELL  
AS A FRONTAL SYSTEM AND AMPLE MOISTURE, WILL LEAD TO RAIN AND  
THUNDERSTORMS FARTHER EAST IN THE SOUTHEAST AND MID-ATLANTIC ON  
SUNDAY NIGHT. THERE IS A SLIGHT RISK OF FLASH FLOODING OVER PARTS  
OF THE CAROLINAS THROUGH SUNDAY NIGHT. ON MONDAY, THE RAIN WILL  
INCREASE IN THE LOWER MISSISSIPPI VALLEY AND OHIO VALLEY TO THE  
SOUTHEAST AND MID-ATLANTIC. LOCALLY HEAVY RAINFALL IS POSSIBLE,  
AND THE GREATEST CHANCE OF FLASH FLOODING WILL BE IN THE LOWER  
MISSISSIPPI VALLEY. MORE RAIN IS EXPECTED ON TUESDAY AS THE FRONT  
REMAINS GENERALLY STATIONARY FROM THE OHIO VALLEY THROUGH THE  
LOWER MISSISSIPPI VALLEY.  
 
THE WESTERN U.S. WILL CONTINUE TO SEE WARMER THAN AVERAGE  
TEMPERATURES THROUGH THE BEGINNING OF THE WORKWEEK UNDER AN  
UPPER-LEVEL RIDGE. HEAT ADVISORIES ARE SCATTERED THROUGHOUT THE  
WEST, WITH EXCESSIVE HEAT WATCHES CURRENTLY IN THE NORTHERN GREAT  
BASIN FOR MONDAY AND TUESDAY, WHERE IT MAY REACH 100 DEGREES.  
OVERNIGHT LOWS ARE FORECAST TO BE WARM, WITH RECORD HIGH MINIMUM  
TEMPERATURES POSSIBLE. POOR AIR QUALITY COULD BE AN ISSUE ACROSS  
PARTS OF THE WEST. SCATTERED MONSOON THUNDERSTORMS WILL BE  
POSSIBLE IN THE SOUTHWEST, MAINLY IN THE AFTERNOON AND EVENING  
EACH DAY.
