...SEVERE THUNDERSTORMS AND FLASH FLOODING WILL IMPACT PORTIONS OF  
THE GULF COAST TONIGHT AND THE SOUTHEAST ON TUESDAY...

A SLOW-MOVING FRONTAL BOUNDARY EXTENDING ALONG THE GULF COAST WILL  
REMAIN A FOCUS FOR UNSETTLED WEATHER, WITH SEVERE THUNDERSTORMS  
AND HEAVY RAIN EXPECTED TO IMPACT PORTIONS OF THE REGION THROUGH  
TUESDAY. ONGOING SHOWERS AND STORMS ARE LIKELY TO CONTINUE  
THROUGH TONIGHT, WITH SEVERE STORMS EXPECTED FROM SOUTH-CENTRAL  
AND SOUTHEAST TEXAS ACROSS SOUTHERN LOUISIANA, AS WELL AS THE  
FLORIDA PANHANDLE. THE STORM PREDICTION CENTER (SPC) HAS  
HIGHLIGHTED THESE AREAS WITH AN ENHANCED RISK (LEVEL 3/5) FOR  
SEVERE WEATHER, INDICATING THE POTENTIAL EXISTS FOR MULTIPLE  
CORRIDORS OF DAMAGING WINDS, VERY LARGE HAIL, AND A FEW TORNADOES.  
IN ADDITION TO THE SEVERE WEATHER THREAT, ABUNDANT MOISTURE  
POOLING ALONG FRONT WILL SUPPORT HEAVY RAINFALL AND THE POTENTIAL  
FOR FLOODING. A SLIGHT RISK (LEVEL 2/4) FOR EXCESSIVE RAINFALL  
EXTENDS ALONG THE GULF COAST FROM SOUTHEAST TEXAS THROUGH THE  
FLORIDA PANHANDLE, WITH A MODERATE RISK (LEVEL 3/4) FROM SOUTHEAST  
LOUISIANA TO THE FLORIDA PANHANDLE.  
 
DRIER AIR WILL PUSH THROUGH THE WESTERN GULF COAST, CONFINING THE  
THREAT FOR SEVERE STORMS AND HEAVY RAINFALL TO NORTHERN FLORIDA  
AND SOUTHERN GEORGIA ON TUESDAY. SPC IS INDICATING A SLIGHT RISK  
(LEVEL 2/5) FOR SEVERE WEATHER AND WPC IS HIGHLIGHTING THE AREA  
WITH A SLIGHT RISK FOR EXCESSIVE RAINFALL.  
 
FURTHER TO THE NORTH, A LOW PRESSURE SYSTEM WILL DRIFT SLOWLY  
EAST, SPREADING SHOWERS AND THUNDERSTORMS FROM THE LOWER MISSOURI  
AND MID MISSISSIPPI VALLEYS TO THE OHIO VALLEY TONIGHT. SHOWERS  
AND STORMS WILL CONTINUE ACROSS THESE AREAS ON TUESDAY WHILE  
EXPANDING EAST THROUGH THE MID-ATLANTIC AND THE NORTHEAST.  
UNSETTLED WEATHER WILL PERSIST ACROSS THE MID-ATLANTIC AND THE  
NORTHEAST THROUGH WEDNESDAY. A BRIEF WINDOW OF DRIER WEATHER OVER  
THE MISSISSIPPI VALLEY LATE TUESDAY INTO EARLY WEDNESDAY WILL BE  
FOLLOWED BY THE NEXT ROUND OF SHOWERS AND STORMS THAT WILL BEGIN  
TO SPREAD INTO THE REGION BY LATE WEDNESDAY.  
 
BEFORE IMPACTING THE CENTRAL U.S. ON WEDNESDAY, THIS PREVIOUSLY  
NOTED SYSTEM WILL SPREAD SHOWERS AND STORMS FOLLOWED BY MUCH  
COOLER TEMPERATURES FROM THE NORTHERN ROCKIES INTO CENTRAL ROCKIES  
AND HIGH PLAINS ON TUESDAY.  
 
TEMPERATURES WILL REMAIN WELL ABOVE-NORMAL, WITH NEAR TO RECORD  
HIGH TEMPERATURES EXPECTED ACROSS SOUTH FLORIDA TUESDAY AND  
WEDNESDAY. WHILE NOT EXPECTED TO BE RECORD-SETTING, TEMPERATURES  
WILL BUILD ACROSS MUCH OF THE WEST, REACHING WELL-ABOVE NORMAL  
HIGHS ACROSS THE REGION BY MIDWEEK.
