CONCERNING...SEVERE THUNDERSTORM WATCH 780...

VALID 130619Z - 130715Z

WW MAY BE REQUIRED FOR SERN MN INTO PARTS OF WRN WI AND FAR NERN IA.

OUTFLOW BOUNDARY ASSOCIATED WITH LEADING EDGE OF FORWARD PROPAGATING
MCS ACROSS THE UPPER MS VALLEY/WRN GREAT LAKES REGION EXTENDED FROM
SAWYER/RUSK COUNTIES WI SSWWD TO BUFFALO COUNTY WI AND THEN WWD TO
SOUTH CENTRAL MN INTERSECTING A BOW ECHO OVER THIS PART OF MN. THIS
SRN MN BOW IS MOVING ENEWD AT 40 KT INTO AN UNSTABLE ENVIRONMENT
ALONG AND AHEAD OF THE LEADING CONVECTIVE OUTFLOW BOUNDARY.  THUS...
A THREAT FOR DAMAGING WINDS IS EXPECTED TO SPREAD ACROSS SERN MN
THROUGH 08Z.  

IF THE LEADING OUTFLOW BOUNDARY CONTINUES TO MOVE FARTHER SSEWD OVER
WRN WI DURING THE NEXT FEW HOURS...THEN THIS BOUNDARY WILL LIKELY
UNDERCUT THE ENEWD MOVING BOW ECHO OVER SRN MN.  THIS WOULD LIMIT
THE THREAT FOR DAMAGING WINDS EWD INTO WRN WI. 

ADDITIONAL ELEVATED STORMS SHOULD CONTINUE TO POSE AN ISOLATED
THREAT FOR STRONG TO SEVERE STORMS...AS THE NRN PORTION OF THE SRN
MN BOW ECHO TRACKS ENEWD ATOP A MORE STABLE AIR MASS IN THE WAKE OF
THE LEADING BOW ECHO NOW OVER NRN WI.
