..HEAVY RAINS TO IMPACT NEW ENGLAND
 
 
...RISK OF FLASH FLOODING AND SEVERE WEATHER FOR THE  
CENTRAL/SOUTHERN ROCKIES AND CENTRAL HIGH PLAINS...  
 
...DANGEROUS HEAT TO CONTINUE ACROSS THE SOUTHWEST AND PORTIONS OF  
THE WEST COAST...  
 
THE HEAVY RAIN THAT HAS PLAGUED THE MID-ATLANTIC AND CAROLINAS HAS  
FINALLY MOVED OFF SHORE AND DRY CONDITIONS WILL SETTLE IN FOR NOW.  
MEANWHILE, THE COLD FRONT THAT HAS USHERED THE RAINFALL TO EXIT  
THESE REGIONS WILL PUSH ACROSS THE NORTHEAST AND NEW ENGLAND  
TODAY. HEAVY RAINFALL WILL MOVE ACROSS MAINE WHERE THERE IS A  
SLIGHT RISK OF FLASH FLOODING. MEANWHILE, ANOTHER ROUND OF SHOWERS  
AND THUNDERSTORMS WITH AN INCOMING COLD FRONT WILL OCCUR FROM THE  
CENTRAL APPALACHIANS, MID-ATLANTIC NORTHWARD INTO NEW ENGLAND ON  
FRIDAY AFTERNOON/EVENING. SOME OF THESE THUNDERSTORMS COULD BE  
SEVERE; THUS, THE STORM PREDICTION CENTER HAS HIGHLIGHTED THE  
MID-ATLANTIC AND PORTIONS OF THE NORTHEAST IN A SLIGHT RISK.  
SHOWERS AND THUNDERSTORMS CAN ALSO BE EXPECTED DURING THIS TIME IN  
THE COASTAL CAROLINAS.  
 
THE CENTRAL AND SOUTHERN ROCKIES WILL CONTINUE TO RECEIVE ROUNDS  
OF THUNDERSTORMS OVER THE NEXT FEW DAYS. SOME OF THESE STORMS  
COULD PRODUCE HEAVY RAINFALL THAT MAY LEAD TO FLASH  
FLOODING--ESPECIALLY OVER FAVORED TERRAIN AND RECENT BURN SCARS.  
FOR TODAY, THE HEAVY RAINFALL WILL MOSTLY CONCENTRATE ACROSS THE  
SOUTHERN AND CENTRAL ROCKIES. BY FRIDAY, THE AXIS OF HEAVY  
RAINFALL AND THE RISK OF SEVERE THUNDERSTORMS WILL SHIFT TO THE  
CENTRAL HIGH PLAINS.  
 
THE DANGEROUS HEAT WILL PERSEVERE INTO FRIDAY AS TEMPERATURES  
ACROSS THE SOUTHWEST, CALIFORNIA AND PARTS OF THE PACIFIC  
NORTHWEST CONTINUE TO BE WELL ABOVE AVERAGE. AREAS IN THE  
SOUTHWEST AND SOUTHERN CALIFORNIA CAN EXPECT HIGH TEMPERATURES  
NEAR AND ABOVE 110 DEGREES. THIS HEAT IS EXPECTED THROUGH AT  
LEAST FRIDAY--WHERE EXCESSIVE HEAT WARNINGS AND HEAT ADVISORIES  
ARE ISSUED. BECAUSE OF THESE HOT AND DRY CONDITIONS, FIRE WEATHER  
WILL REMAIN A CONCERN ACROSS THE WESTERN U.S.
