HURRICANE CHRIS IS EXPECTED TO PICK UP THE PACE AND TRACK FURTHER  
NORTHEAST OUT OVER THE ATLANTIC OCEAN, WHILE TRANSITIONING TO A  
POST-TROPICAL SYSTEM. AS IT CONTINUES TO SHIFT AWAY FROM THE  
COAST, IMPACTS WILL LESSON ALONG THE COAST LINES THIS EVENING AND  
THROUGH THE OVERNIGHT. FOR THE MOST CURRENT INFORMATION REGARDING  
CHRIS, VISIT THE NATIONAL HURRICANE CENTER (WWW.HURRICANES.GOV)  
AND THE LOCAL FORECAST OFFICE FOR INDIVIDUAL  
WATCHES/WARNINGS/ADVISORIES.  
 
A STRONG COLD FRONT WILL CONTINUE TO SHIFT EASTWARD ACROSS THE  
NORTH-CENTRAL U.S., RESULTING IN THE RISK OF SEVERE WEATHER ACROSS  
THE NORTHERN PLAINS AND UPPER MISSISSIPPI VALLEY TONIGHT THROUGH  
THURSDAY. THIS WILL COUPLE WITH A VERY MOIST ATMOSPHERE, AND MAY  
ALSO RESULT IN THE POTENTIAL OF EXCESSIVE RAINFALL AND FLASH  
FLOODING FOR PORTIONS OF THIS REGION THROUGH THE OVERNIGHT  
TONIGHT. EXCESSIVE RAIN CONCERNS MAY ALSO CONTINUE INTO THE DAY  
THURSDAY FOR PORTIONS OF THE NORTHERN PLAINS.  
 
COVERAGE OF SHOWERS AND THUNDERSTORMS WILL INCREASE ACROSS THE  
SOUTHWEST THROUGH THE END OF THE WEEK AS MONSOONAL MOISTURE SURGES  
NORTH. HEAVY RAINFALL ALONG THE TERRAIN COULD LEAD TO FLASH  
FLOODING IN ADDITION TO FLOOD PRONE AREAS. BY THURSDAY, HEAVY  
RAINFALL WILL CONTINUE IN THE SOUTHWEST BUT ALSO BEGIN TO SPREAD  
INTO THE SOUTHERN AND CENTRAL ROCKIES. THERE IS A SLIGHT RISK OF  
FLASH FLOODING IN THE SOUTHWEST TODAY WITH THE SLIGHT RISK  
SHIFTING EASTWARD BY THURSDAY ALONG THE ROCKIES.
