..DANGEROUS HEAT CONTINUES ACROSS THE SOUTHEAST AND SOUTHWEST
ACROSS THE SOUTHEAST, HOT AND HUMID CONDITIONS WILL PERSIST AND

ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER PARTS
OF THE UPPER/MIDDLE MISSISSIPPI VALLEY TO THE CENTRAL PLAINS ON

AND LOW-LYING AREAS BEING THE MOST VULNERABLE. IN ADDITION,
SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER PARTS OF THE
MID-ATLANTIC/CENTRAL APPALACHIANS, INTO THE SOUTHERN

THUNDERSTORMS FROM LATE AFTERNOON INTO THE LATE EVENING ON
