VALID 080539Z - 080715Z A LARGE-SCALE BOW ECHO WILL HAVE A WIND DAMAGE AND HAIL POTENTIAL AS IT MOVES EWD ACROSS MN OVERNIGHT. A NEW WW WILL LIKELY BECOME NECESSARY EAST OF WW 432. WATER VAPOR IMAGERY AND RUC ANALYSIS SHOWS A SHORTWAVE TROUGH ROTATING NEWD AROUND AN LARGE UPPER-LOW CENTER OVER THE NWRN STATES. THIS WILL DRIVE THE CONVECTIVE LINE EWD ACROSS MN OVER THE NEXT FEW HOURS. SFC ANALYSIS SHOWS A NEARLY STATIONARY FRONT/OUTFLOW BOUNDARY EXTENDING EWD FROM NE SD ACROSS SCNTRL MN. THE MOST SEVERE STORMS SHOULD TRAVEL EWD AND NEWD ALONG THE BOUNDARY AXIS WHERE MODERATE INSTABILITY IS IN PLACE.
