BASED ON THE LATEST FORECAST ADVISORY FROM THE NATIONAL HURRICANE  
CENTER, SUBTROPICAL STORM ALBERTO WILL MAKE LANDFALL THIS  
AFTERNOON IN THE FLORIDA PANHANDLE WITH GRADUAL WEAKENING OF THE  
STORM EXPECTED AS IT MOVES INLAND OVER ALABAMA AND INTO THE  
TENNESSEE VALLEY AND THE OHIO VALLEY BY LATE TUESDAY INTO  
WEDNESDAY. BANDS OF HEAVY RAINFALL AND GUSTY WINDS ARE ONGOING  
THIS AFTERNOON ACROSS PARTS OF THE SOUTHEAST, WITH A SLIGHT RISK  
FOR TORNADOES AS WELL. THE HEAVIEST RAINFALL IS EXPECTED TO BE  
NEAR THE CENTER OF CIRCULATION AS IT TRACKS NORTHWARD TOWARDS THE  
TENNESSEE AND OHIO VALLEYS. WPC CONTINUES TO MONITOR A MODERATE TO  
HIGH RISK FOR FLASH FLOODING ACROSS THE FLORIDA PANHANDLE, EASTERN  
AND CENTRAL ALABAMA, AND FAR WESTERN GEORGIA THROUGH TONIGHT. A  
SLIGHT RISK IS HIGHLIGHTED FOR THE TENNESSEE VALLEY AND INTO THE  
LOWER OHIO VALLEY TUESDAY AND INTO WEDNESDAY. A SECONDARY AXIS OF  
RAINFALL MAXIMA IS ALSO POSSIBLE ACROSS PARTS OF THE CENTRAL  
APPALACHIANS AND THE CAROLINAS ALONG A SURFACE TROUGH TO THE  
NORTHEAST OF ALBERTO'S CIRCULATION. ELSEWHERE, GENERAL RAINFALL  
AMOUNTS SHOULD BE MODEST IN COMPARISON TO THE GULF COAST INTO THE  
TENNESSE VALLEY, BUT IT WILL LIKELY REMAIN QUITE WET OVER ALL OF  
THE DEEP SOUTH INTO THE OHIO VALLEY AND THE MID-ATLANTIC.  
 
IN ADVANCE OF AN EXPANSIVE UPPER LEVEL LOW OVER THE GREAT BASIN, A  
NORTH-SOUTH ORIENTED FRONT AND DRY LINE OVER THE SOUTHERN/CENTRAL  
HIGH PLAINS WILL CONTINUE TO BE A FOCUS FOR ACTIVE CONVECTION  
TONIGHT AND ON TUESDAY. DEVELOPING STORMS ACROSS THIS REGION WILL  
BE CAPABLE OF PRODUCING SEVERE WEATHER AND HEAVY RAINFALL. THE  
LATEST OUTLOOK FROM THE STORM PREDICTION CENTER HAS PARTS OF THE  
CENTRAL/SOUTHERN HIGH PLAINS WITHIN A SLIGHT TO ENHANCED RISK FOR  
SEVERE WEATHER THIS EVENING, MOVING EASTWARD INTO CENTRAL OKLAHOMA  
AND CENTRAL KANSAS BY TUESDAY. GENERAL SCATTERED SHOWERS AND  
THUNDERSTORMS ARE ALSO EXPECTED ACROSS PARTS OF THE INTERMOUNTAIN  
WEST AND INTO THE UPPER MIDWEST/MISSISSIPPI VALLEY.  
 
AHEAD OF THIS SYSTEM, STRONG UPPER LEVEL RIDGING ANCHORED OVER  
TEXAS WILL KEEP RECORD BREAKING WARMTH IN THE FORECAST THROUGH  
MID-WEEK. AFTERNOON HIGH VALUES COULD BE IN THE HIGH 90S TO LOW  
100S, WHICH IS 10 TO 20 DEGREES ABOVE NORMAL. ABOVE NORMAL  
TEMPERATURES ARE EXPECTED ALL ACROSS THE GREAT PLAINS AND INTO THE  
UPPER MIDWEST AS WELL.
