...MORE ACTIVE WEATHER ACROSS THE MID SECTIONS OF THE NATION, WITH  
ADDITIONAL ROUNDS OF THUNDERSTORMS, HEAVY RAINS, FLASH FLOODING  
AND SEVERE WEATHER...  
 
...HEAT TO CONTINUE ACROSS THE SOUTHWEST TO SOUTH TEXAS AND MUCH  
OF FLORIDA, WHILE BUILDING ACROSS THE INLAND VALLEYS OF  
CALIFORNIA...  
 
...COOLER THAN AVERAGE TEMPERATURES FOR THE PLAINS AND LARGE  
PORTIONS OF THE EASTERN U.S. THROUGH EARLY THIS WEEKEND...  
 
A TUMULTUOUS WEATHER PATTERN SPARKING SEVERAL ROUNDS OF ROBUST  
THUNDERSTORMS IS SET TO CONTINUE THROUGHOUT MUCH OF THE CENTRAL  
AND SOUTH-CENTRAL UNITED STATES. THE ATMOSPHERIC INGREDIENTS IN  
PLAY FOR THE NEXT SERVING OF SEVERE WEATHER INCLUDE AN UPPER  
TROUGH WITH EMBEDDED SHORTWAVES CROSSING THE ROCKIES TODAY,  
MULTIPLE FRONTAL BOUNDARIES DRAPED ACROSS THE GREAT PLAINS, AND  
AMPLE ATMOSPHERIC MOISTURE CONTENT LIFTING NORTHWARD FROM THE  
WESTERN GULF OF MEXICO. ADDITIONALLY, A REEMERGING DRYLINE OVER  
THE SOUTHERN HIGH PLAINS WILL HELP SPARK STRONG STORMS THIS  
AFTERNOON THAT ARE FORECAST TO PROGRESS EASTWARD TONIGHT OVER THE  
SOUTHERN PLAINS. THESE THUNDERSTORMS MAY CONTAIN LARGE HAIL AND  
DAMAGING WIND GUSTS, WITH THE LOCATIONS MOST LIKELY IMPACTED  
INCLUDING THE TEXAS PANHANDLE AND PARTS OF WEST TEXAS. A BROADER  
THREAT FOR ISOLATED SEVERE WEATHER STRETCHES THROUGHOUT A MAJORITY  
OF THE CENTRAL AND SOUTHERN PLAINS. INTENSE RAINFALL RATES ARE  
ALSO POSSIBLE AND CAN LEAD TO FLASH FLOODING WHERE STORM MOTIONS  
ARE SLOW. CURRENTLY, THE SCATTERED FLASH FLOOD THREAT INCLUDES  
MUCH OF THE CENTRAL/SOUTHERN PLAINS AND ARKLATEX REGION. THE  
ACTIVE WEATHER AND CLUSTERS OF REDEVELOPING THUNDERSTORMS ARE THEN  
FORECAST TO GRADUALLY SLIDE EASTWARD ON FRIDAY AS AN AREA OF LOW  
PRESSURE PUSHES ACROSS THE RED RIVER VALLEY OF THE SOUTH.  
ADDITIONAL CHANCES FOR DAMAGING WIND GUSTS AND LARGE HAIL EXISTS  
ACROSS CENTRAL AND EASTERN TEXAS, AS WELL AS INTO THE LOWER  
MISSISSIPPI VALLEY. FLASH FLOODING ALSO REMAINS A CONCERN FOR THE  
LAST DAY OF MAY ACROSS THE SOUTHERN PLAINS AND LOWER MISSISSIPPI  
VALLEY. WET WEATHER IS ANTICIPATED TO EXPAND TO START THE WEEKEND,  
BUT WITH LESS FOCUS FOR SEVERE WEATHER AS THUNDERSTORM CHANCES  
STRETCH FROM THE OHIO/TENNESSEE VALLEYS TO THE GREAT PLAINS.  
 
STORMINESS OVER THE CENTRAL U.S. WILL KEEP HIGH TEMPERATURES BELOW  
AVERAGE TO END THE WEEK, WHILE A POTENT HIGH PRESSURE SYSTEM OVER  
THE LOWER GREAT LAKES AND OHIO VALLEY ALSO OFFERS REFRESHING  
AFTERNOON TEMPERATURES IN THE 70S FOR LARGE SECTIONS OF THE  
EASTERN UNITED STATES. SUMMER HEAT WILL BE CONTINUE TO BE FOUND  
ACROSS THE SOUTHWEST AND SOUTHERN TIER. MUGGY HIGHS INTO THE  
MID-90S ARE FORECAST ACROSS THE CENTRAL/SOUTHERN FLORIDA PENINSULA  
UNTIL A COLD FRONT ENTERS ON SATURDAY AND OFFERS SOME MUCH NEEDED  
RELIEF IN THE FORM OF PERSISTENT NORTHEASTERLY FLOW. UPPER 90S AND  
LOW 100S ARE ANTICIPATED TO STRETCH FROM THE SOUTHWEST TO FAR  
WESTERN AND SOUTHERN TEXAS THROUGH THE WEEKEND. HEAT WILL ACTUALLY  
BUILD FURTHER NORTH INTO THE GREAT BASIN AND INTERIOR CALIFORNIA  
VALLEYS AS WELL, BUT NOT QUITE WARM ENOUGH TO APPROACH DAILY  
RECORDS. IF SPENDING TIME OUTDOORS IN THESE REGIONS, BE SURE TO  
FOLLOW PROPER HEAT SAFETY.
