NWS WEATHER PREDICTION CENTER COLLEGE PARK MD  
333 AM EDT SAT MAY 11 2024  
 
VALID 12Z SAT MAY 11 2024 - 12Z MON MAY 13 2024  
 
...WET WEEKEND IN STORE FOR THE CENTRAL/SOUTHERN PLAINS AND  
ADJACENT ROCKIES...  
 
...HEAVY RAINFALL AND FLASH FLOODING POSSIBLE FOR PARTS OF THE  
SOUTH AND SOUTHEAST SUNDAY THROUGH TUESDAY...  
 
...ABOVE AVERAGE TEMPERATURES FORECAST FOR THE WEST AND  
NORTH-CENTRAL U.S. THIS WEEKEND...  
 
PRECIPITATION CHANCES WILL CONTINUE TODAY FOR PORTIONS OF THE  
CENTRAL/SOUTHERN PLAINS AND ADJACENT ROCKIES, AND COVERAGE IS  
EXPECTED TO INCREASE WITH WIDESPREAD SHOWERS AND THUNDERSTORMS  
FORECAST TO IMPACT THE PLAINS TODAY. LOCALLY HEAVY RAINFALL AND  
ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE EAST OF A STALLED  
FRONTAL BOUNDARY DRAPED UP AGAINST THE ROCKIES. POTENTIAL STORM  
HAZARDS WILL INCLUDE HAIL, STRONG WIND GUSTS, AND ISOLATED FLASH  
FLOODING. IN THE HIGHER ELEVATIONS WEST OF THE FRONTAL BOUNDARY,  
WINTRY PRECIPITATION IS EXPECTED, AND SOME OF THE HIGHER PEAKS IN  
COLORADO AND NORTHERN NEW MEXICO COULD RECEIVE A FEW ADDITIONAL  
INCHES OF SNOW.  
 
THE SURFACE FRONT IS EXPECTED TO REMAIN IN PLACE THROUGH TONIGHT,  
THEN THE FRONT WILL BEGIN TO LIFT NORTH AS A WARM FRONT ACROSS  
TEXAS AND THE LOWER MISSISSIPPI VALLEY ON SUNDAY WHILE LOW  
PRESSURE DEEPENS OVER THE PLAINS. ANOTHER ROUND OF WIDESPREAD  
SHOWERS AND THUNDERSTORMS WILL DEVELOP ON SUNDAY, AND THE THREAT  
OF HEAVY RAINFALL WILL INCREASE AS WARM GULF AIR MOVES INTO THE  
REGION. THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL (LEVEL 2/4)  
FROM CENTRAL TEXAS EAST TO THE MISSISSIPPI RIVER. SCATTERED  
INSTANCES OF FLASH FLOODING WILL BE POSSIBLE, ESPECIALLY WHERE  
SOILS ARE STILL MOIST AFTER RECENT HEAVY RAINS. THE DEVELOPING LOW  
PRESSURE SYSTEM IS FORECAST TO PUSH EAST ACROSS THE LOWER  
MISSISSIPPI VALLEY TOWARDS THE SOUTHEAST ON MONDAY AND TUESDAY,  
AND THE HEAVY RAINFALL/FLASH FLOOD THREAT WILL SHIFT EAST ACROSS  
THE NORTHERN GULF COAST STATES.  
 
TO THE EAST, PRECIPITATION CHANCES WILL RETURN TO THE MID-ATLANTIC  
AND GREAT LAKES REGIONS TODAY AS AN OCCLUDED FRONTAL SYSTEM PUSHES  
TOWARDS THE EAST COAST. SHOWERS AND THUNDERSTORMS WILL LINGER INTO  
SUNDAY MORNING BEFORE THE SYSTEM MOVES OFFSHORE SUNDAY AFTERNOON.  
ANOTHER FRONTAL SYSTEM WILL DROP SOUTH INTO THE NORTH-CENTRAL U.S.  
OVER THE WEEKEND, WHICH MAY RENEW PRECIPITATION CHANCES NEAR THE  
WESTERN GREAT LAKES ON SUNDAY. OTHER AREAS OF THE COUNTRY SHOULD  
REMAIN MOSTLY DRY THROUGH MONDAY.  
 
UPPER-LEVEL RIDGING OVER THE WEST COAST AND NORTH-CENTRAL U.S.  
WILL LEAD TO WELL-ABOVE AVERAGE TEMPERATURES IN THESE REGIONS  
THROUGH THE WEEKEND. HIGH TEMPERATURES THIS AFTERNOON WILL RANGE  
FROM THE 80S TO LOWER 90S IN CALIFORNIA AND THE PACIFIC NORTHWEST  
AND FROM THE 70S TO LOWER 80S IN THE NORTHERN PLAINS. THE FOCUS  
FOR WARMER TEMPERATURES WILL SHIFT MORE INTO THE INTERIOR  
WEST/GREAT BASIN AND UPPER MIDWEST ON SUNDAY. BELOW AVERAGE  
TEMPERATURES ARE FORECAST ELSEWHERE ACROSS THE EASTERN AND CENTRAL  
U.S. THROUGH THE WEEKEND, BUT TEMPERATURE WILL TREND BACK TOWARDS  
NORMAL EARLY IN THE WORK WEEK.
