...SEVERE THUNDERSTORMS POSSIBLE ACROSS PORTIONS OF NEW MEXICO  
TODAY...  
 
...ONE MORE DAY OF WET WEATHER AND POSSIBLE HEAVY RAINFALL FOR THE  
MID-ATLANTIC...  
 
...ABOVE NORMAL AND CLOSE TO RECORD BREAKING TEMPERATURES WILL  
CONTINUE FOR PORTIONS OF THE SOUTHERN PLAINS TO THE SOUTHEAST...  
 
SHOWERS AND THUNDERSTORMS WILL CONTINUE TODAY ALONG A COLD FRONT  
FROM THE OHIO VALLEY TO THE DEEP SOUTH, WITH A MARGINAL THREAT FOR  
SEVERE WEATHER AND HEAVY RAINFALL. ORGANIZED RAINFALL SHOULD MOVE  
INTO THE NORTHEAST BY MONDAY AS THE ASSOCIATED UPPER LEVEL SYSTEM  
ROTATES ACROSS THE REGION. ON THE WESTERN EDGE OF THIS FRONT,  
RETURN MOISTURE INTO THE SOUTHERN ROCKIES WILL INTERACT WITH UPPER  
LEVEL ENERGY SCOOTING EASTWARD INTO THE FOUR CORNERS REGION.  
NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP TODAY  
AS A RESULT WITH HEAVY RAINFALL AND SEVERE WEATHER POSSIBLE. THE  
STORM PREDICTION CENTER HAS HIGHLIGHTED PORTIONS OF NEW MEXICO  
WITHIN A SLIGHT RISK.  
 
MUCH OF THE MID-ATLANTIC WILL HAVE TO ENDURE ONE MORE DAY OF WET  
WEATHER AS AN UPPER LEVEL LOW MEANDERS ACROSS THE REGION WITHIN AN  
INCREDIBLY MOIST ATMOSPHERE. NUMEROUS SHOWERS AND THUNDERSTORMS  
ARE EXPECTED, WITH HEAVY RAINFALL POSSIBLE. ALTHOUGH THE FLASH  
FLOOD THREAT IS LOWER THAN PREVIOUS DAYS, ISOLATED FLASH FLOODING  
CANNOT BE RULED OUT GIVEN THE ALREADY VERY SATURATED SOILS. AS  
SUCH, THERE IS A MARGINAL TO SLIGHT RISK SHOWN ON THE WPC DAY 1  
EXCESSIVE RAINFALL GRAPHIC. BY MONDAY, THE UPPER LEVEL LOW SHOULD  
FINALLY MOVE OFFSHORE WITH MUCH DRYER CONDITIONS EXPECTED TO START  
THE NEW WORK WEEK.  
 
AS FOR TEMPERATURES ACROSS THE COUNTRY, LOCATIONS FROM THE FAR  
SOUTHERN PLAINS TO THE SOUTHEAST WILL CONTINUE TO EXPERIENCE ABOVE  
NORMAL TEMPERATURES UNDERNEATH STUBBORN RIDGING IN THE UPPER  
LEVELS. ACROSS DEEP SOUTH TEXAS, AFTERNOON HIGHS COULD BE IN THE  
UPPER 90S TO LOW 100S, WHICH WOULD CERTAINLY APPROACH DAILY  
RECORDS. VERY WARM OVERNIGHT TEMPERATURES IN THE 70S ARE ALSO  
EXPECTED FROM SOUTH TEXAS AND POINTS EASTWARD, WHICH COULD  
APPROACH OR BREAK RECORD OVERNIGHT HIGH MINIMUMS FOR A HANDFUL OF  
LOCATIONS. ELSEWHERE, MUCH OF THE WESTERN U.S. WILL ALSO SEE ABOVE  
NORMAL TEMPERATURES WITH BUILDING UPPER LEVEL RIDGING, BUT COLDER  
THAN AVERAGE TEMPERATURES, ON THE ORDER OF 5 TO 15 DEGREES BELOW  
NORMAL, WILL CONTINUE SUNDAY AND MONDAY FOR MUCH OF THE UPPER  
MIDWEST TO THE NORTHEAST.
