...WW WILL LIKELY BE REQUIRED DOWNSTREAM PRIOR TO 04Z...

ISOLATED SUPERCELLS CONTINUE THEIR SEWD MOVEMENT AT ROUGHLY 40 KT
ACROSS SULLY AND POTTER COUNTIES.  THIS ACTIVITY IS MOVING INTO
INCREASINGLY MOIST BOUNDARY LAYER WHERE SFC DEW POINTS HAVE RISEN
INTO THE LOWER-MID 70S.  ALTHOUGH THIS CONVECTION IS MAINTAINING
DISCRETE STRUCTURES...WITH TIME STORM MERGERS AND CLUSTERING MAY
RESULT IN A SEWD PROPAGATING MCS.  IF AN MCS EVOLVES...DAMAGING
WINDS WILL BECOME INCREASINGLY LIKELY. OTHERWISE...ISOLATED
TORNADOES MAY YET DEVELOP ALONG WITH VERY LARGE HAIL.  CURRENT
TRENDS SUGGEST LEADING STORMS MAY EXIT SRN PORTIONS OF WW AROUND
0430Z.
