MOISTURE STREAMING NORTHWARD INTO THE EASTERN U.S. THIS AFTERNOON  
AHEAD OF A COLD FRONT WILL CONTINUE TO ALLOW FOR THE DEVELOPMENT  
OF SHOWERS AND THUNDERSTORMS FROM THE DEEP SOUTH TO THE NORTHEAST  
TONIGHT. CONDITIONS APPEAR FAVORABLE FOR SOME SEVERE WEATHER, WITH  
THE STORM PREDICTION CENTER HIGHLIGHTING A SLIGHT RISK ACROSS  
PARTS OF THE NORTHERN APPALACHIANS THIS AFTERNOON AND INTO THE  
EVENING. STORMS SHOULD CLEAR OUT BY THURSDAY ACROSS THE NORTHEAST  
AND MID-ATLANTIC REGIONS, BUT MAY CONTINUE ACROSS THE DEEP SOUTH  
INTO THURSDAY AS THE BOUNDARY LINGERS ACROSS THE REGION. THE  
WESTERN PORTION OF THIS BOUNDARY WILL BEGIN LIFTING AS A WARM  
FRONT ACROSS THE CENTRAL PLAINS, WHERE ADDITIONAL SHOWERS AND  
STORMS (MAYBE SEVERE) ARE EXPECTED TONIGHT.  
 
A STRONG COLD FRONT PUSHING INTO THE NORTHWEST STATES TODAY, WILL  
MOVE INTO THE NORTHERN PLAINS BY THURSDAY. MOISTURE AHEAD OF THIS  
SYSTEM WILL ALLOW FOR THE DEVELOPMENT OF NUMEROUS SHOWERS AND  
THUNDERSTORMS ALONG THE BOUNDARY, WITH SOME STORMS CONTAINING  
HEAVY TO EXCESSIVE RAINFALL AND/OR SEVERE WEATHER POSSIBLE. SPC  
HAS A SLIGHT TO ENHANCED RISK FOR SEVERE WEATHER ACROSS THE  
DAKOTAS AND INTO WESTERN MINNESOTA ON THURSDAY, WHILE WPC IS  
HIGHLIGHTING A SLIGHT RISK FOR FLASH FLOODING ACROSS PARTS OF THE  
NORTHERN PLAINS TO THE UPPER MIDWEST ALONG THE ATTENDANT WARM  
FRONT AS IT LIFTS THROUGH THE REGION THURSDAY INTO FRIDAY. SEE THE  
OUTLOOKS FROM THESE TWO CENTERS FOR ADDITIONAL DETAILS ON THE  
SEVERE WEATHER AND FLASH FLOOD THREAT. AHEAD OF THIS SYSTEM,  
RIDGING IN THE UPPER LEVELS WILL KEEP TEMPERATURES VERY WARM, WITH  
AFTERNOON HIGHS 10 TO 20 DEGREES ABOVE NORMAL POSSIBLE,  
PARTICULARLY ACROSS THE NORTHERN AND CENTRAL PLAINS.  
 
ELSEWHERE, WARM, DRY, AND WINDY CONDITIONS ACROSS PARTS OF THE  
GREAT BASIN WILL CREATE FAVORABLE FIRE WEATHER CONDITIONS.  
NUMEROUS RED FLAG WARNINGS ARE IN EFFECT ACROSS SOUTHERN UTAH AND  
WESTERN COLORADO. MEANWHILE, THE HEATWAVE ACROSS THE SOUTHWEST  
SHOULD SUBSIDE AS MOISTURE AHEAD OF TROPICAL STORM BUD BEGINS  
IMPACTING PARTS OF THE SOUTHWEST BY THE END OF THIS WEEK. REFER TO  
THE NATIONAL HURRICANE CENTER FOR THE LATEST INFORMATION REGARDING
