ANOTHER 1-3 HOURS. AS SUCH...SEVERE THUNDERSTORM WATCH 370 WILL BE

DISCUSSION...A GRADUAL WEAKENING TREND HAS BEEN NOTED IN RADAR DATA
OVER THE LAST HOUR OR SO. THE EXCEPTION IS WITH STORMS JUST NORTH OF
MSP AND FURTHER SOUTH ALONG THE MS RIVER IN FAR NORTHEAST
IA/SOUTHWEST WI. 00Z MESOANALYSIS ALONG WITH THE 00Z MPX RAOB
INDICATE MLCAPE NEAR 1000-1500 J/KG STILL EXISTS WITH STEEP MIDLEVEL

FURTHER EAST OF THE REGION. PER COLLABORATION WITH WFO MPX AND
ARX...SEVERE THUNDERSTORM WATCH 370 WILL BE EXTENDED IN SPACE/TIME.
