POWERFUL SHORT WAVE TROF AND ITS ASSOCIATED VORT MAX WERE MOVING

PROGRESSES THROUGH THE REST OF NE MN THIS MORNING...IT WILL GLANCE
NW WI. HAVE TIMED POPS TO ACCOUNT FOR THE SPEED AND MOVEMENT OF THE
TROF/VORT MAX/MCS THROUGH THE FA. THE BULK OF THE PCPN WILL EXIT THE
FA BY 18Z TODAY. HAVE A SMALL POP OVER THE ARROWHEAD THROUGH 19Z TO
ACCOUNT FOR ANY LINGERING BACKWASH FROM THE DEPARTING SYSTEM.
MEANWHILE...SFC RIDGING BEGINS TO BUILD ACROSS THE AREA FROM MID
MORNING THROUGH THE AFTERNOON. EVENTUALLY...HUMIDITIES WILL DROP AND
MAX TEMPS WILL BE IN THE SEASONAL NORMAL RANGE.

THE SFC RIDING CONTINUES TO BUILD OVER THE FA TONIGHT AND WEDNESDAY.
