...TROPICAL STORM CHRIS WILL CONTINUE TO STRENGTHEN AND LINGER OFF  
THE CAROLINAS, EVENTUALLY BEGINNING TO LIFT AWAY FROM THE COAST BY  
WEDNESDAY...  
 
...SEVERE THUNDERSTORMS POSSIBLE FROM MONTANA TO MINNESOTA THIS  
WEEK, WITH FLASH FLOODING ALSO POSSIBLE ON WEDNESDAY IN PARTS OF  
THE UPPER MISSISSIPPI VALLEY...  
 
...HEAVY RAINFALL AND FLASH FLOODING POSSIBLE ACROSS PORTIONS OF  
THE SOUTHWEST...  
 
AS PER THE LATEST ADVISORY FROM THE NATIONAL HURRICANE CENTER,  
TROPICAL STORM CHRIS IS FORECAST TO STRENGTHEN INTO A HURRICANE AS  
IT LINGERS OFF THE CAROLINAS THROUGH TOMORROW, AND FINALLY BEGIN  
LIFTING NORTH AND EASTWARD AWAY FROM THE EAST COAST BY WEDNESDAY.  
WHILE MUCH OF THE HEAVIEST RAINFALL SHOULD STAY WELL OFFSHORE,  
OUTER RAIN BANDS FROM CHRIS MAY CLIP THE OUTER BANKS OF NORTH  
CAROLINA THROUGH TOMORROW. DESPITE THIS, DANGEROUS SURF AND  
RIP-CURRENTS WILL CONTINUE THROUGH THE NEXT FEW DAYS ALONG THE  
CAROLINA COASTS AS WELL AS FARTHER UP THE MID-ATLANTIC COAST.  
REFER TO THOSE PRODUCTS ISSUED BY THE LOCAL FORECAST OFFICES AS  
WELL AS NHC FOR THE LATEST INFORMATION REGARDING CHRIS AND ITS  
IMPACTS.  
 
EXPECT MAINLY SCATTERED SHOWERS AND THUNDERSTORM TO CONTINUE ALONG  
A COLD FRONT AS IT MOVES EASTWARD THIS EVENING AND ON TUESDAY  
THROUGH THE GREAT LAKES AND INTO THE NORTHEAST. THE WESTERN  
PORTION OF THIS FRONT WILL EVENTUALLY START PUSHING EASTWARD AS A  
COLD FRONT BY TOMORROW ACROSS THE NORTHERN ROCKIES AND HIGH  
PLAINS. RAIN AND THUNDERSTORMS WILL ACCOMPANY THIS FRONT AS IT  
MOVES ACROSS THE NORTHERN PLAINS AND INTO THE UPPER MISSISSIPPI  
VALLEY BY THURSDAY WITH SEVERE THUNDERSTORMS AND HEAVY RAINFALL  
POSSIBLE. THE STORM PREDICTION CENTER HAS HIGHLIGHTED PORTIONS  
MONTANA AND NORTH DAKOTA WITHIN A SLIGHT RISK FOR SEVERE WEATHER  
ON TUESDAY, AND INTO PARTS OF MINNESOTA ON WEDNESDAY. WPC ALSO HAS  
A SLIGHT RISK FOR EXCESSIVE RAINFALL/FLASH FLOODING ALONG THE  
BOUNDARY IN MINNESOTA ON WEDNESDAY.  
 
ELSEWHERE, EXPECT MONSOONAL MOISTURE AND DIURNALLY DRIVEN SHOWERS  
AND THUNDERSTORMS TO CONTINUE IMPACTING PORTIONS OF THE SOUTHWEST,  
GREAT BASIN, AND SOUTHERN ROCKIES THROUGH THE SHORT RANGE PERIOD,  
WITH HEAVY RAINFALL AND FLASH FLOODING A POSSIBILITY WITH WPC  
INDICTING A MARGINAL TO SLIGHT RISK FOR MUCH OF THIS REGION ON ITS  
EXCESSIVE RAINFALL OUTLOOKS. IN THE DEEP SOUTH, SCATTERED SHOWERS  
AND STORMS WILL CONTINUE ACROSS FLORIDA, THE GULF COAST STATES,  
AND PARTS OF THE LOWER MISSISSIPPI VALLEY ALONG AND BEHIND A  
LINGERING STATIONARY BOUNDARY.
