..HEAVY RAINFALL POSSIBLE ACROSS SOUTHERN FLORIDA
 
 
...MAJOR TO HISTORIC RIVER FLOODING WILL CONTINUE ACROSS PARTS OF  
THE MISSISSIPPI AND MISSOURI RIVER BASINS WITH AREAL FLOODING ALSO  
POSSIBLE IN THE NORTHWEST/NORTHERN ROCKIES...  
 
A FRONT LINGERING ACROSS SOUTHERN FLORIDA WILL CONTINUE TO PRODUCE  
SHOWERS AND THUNDERSTORMS THROUGH TUESDAY, WITH LOCALLY HEAVY  
RAINFALL POSSIBLE. FLASH FLOODING SHOULD BE A MARGINAL THREAT AT  
BEST, ESPECIALLY NEAR THE HIGHLY URBANIZED MIAMI AREA. IN THE  
CENTRAL STATES, A COUPLE OF WEAK SYSTEMS MAY BRING MAINLY LIGHT  
RAIN (WITH SNOW POSSIBLE TO THE NORTH) FROM THE CENTRAL PLAINS ON  
TUESDAY, INTO THE MISSISSIPPI VALLEY, GREAT LAKES, AND OHIO VALLEY  
WEDNESDAY INTO THURSDAY. AND A COLD FRONT MOVING INTO CALIFORNIA  
AND THE SOUTHWEST WEDNESDAY AND THURSDAY WILL BRING INCREASED  
CHANCES FOR RAIN AND MOUNTAIN SNOWS TO CALIFORNIA, THE CENTRAL  
GREAT BASIN, AND INTO THE SOUTHWEST/FOUR CORNERS REGION.  
TEMPERATURES EAST OF THE ROCKIES SHOULD BE MOSTLY NEAR OR BELOW  
NORMAL FOR THIS TIME OF THE YEAR WITH THE GREATEST DEPARTURES FROM  
NORMAL ACROSS PARTS OF WEST TEXAS, THE HIGH PLAINS, AND  
FLORIDA/THE SOUTHEAST.  
 
MAJOR TO HISTORIC AND CATASTROPHIC FLOODING WILL CONTINUE ACROSS  
PARTS OF THE MISSOURI AND MISSISSIPPI RIVER BASINS DUE TO RAPID  
SNOWMELT AS A RESULT OF HEAVY RAINFALL LAST WEEK. A ROUND OF LIGHT  
RAIN SHOWERS MOVING THROUGH ON TUESDAY MAY ONLY EXACERBATE  
FLOODING ACROSS THE REGION AS WELL. FLOOD WARNINGS AND ADVISORIES  
REMAIN IN EFFECT, MAINLY FOCUSED ACROSS PARTS OF EASTERN NEBRASKA  
AND WESTERN IOWA. AREAL FLOODING IS ALSO A CONCERN ACROSS PARTS OF  
THE NORTHWEST AND NORTHERN ROCKIES/HIGH PLAINS AS WELL AS WARM  
TEMPERATURES LEAD TO ACCELERATED SNOWMELT AND THE POTENTIAL FOR  
ICE JAMS.
