NATIONAL WEATHER SERVICE DULUTH MN
232 PM CDT MON SEP 1 1997

FORECAST PROBLEM TONIGHT IS DECREASE OF CONVECTIVE ACTIVITY THIS
EVENING AND DECREASING CLOUDS OVERNIGHT.

NO TIME TO REALLY LOOK AT ANYTHING AS HAVE RECENTLY CAME ON THE
PUBLIC DESK. 18Z SFC STREAMLINE AND SFC ANALYSES SHOW THAT COLD
FRONT HAS REACHED A CKC-TWM-BRD LINE. LOWER TROPOSPHERIC THETA-E
RIDGE AHEAD OF THE FRONT IS BEING SHUNTED TO THE SOUTHEAST ACROSS
NW WISCONSIN. SURFACE BASED LIFTED INDICES SHOW MAXIMUM INSTABILITY
MOVING INTO THIS AREA. CURRENT +TSRAGS CELLS MOVING INTO THIS AREA
ATTM AND SVR THUNDERSTORMS SHOULD CONTINUE TO MAINTAIN INTENSITY
INTO THE EARLY EVENING AS THEY TRACK THROUGH THIS AREA.

BEHIND THE FRONT...BAND OF LOW LEVEL SC SHOULD BEGIN TO DISSIPATE
DURING THE EVENING HOURS WITH CLEARING FOR THE NORTHERN MN ZONES
BY 06Z. MODERATE LOW LEVEL COLD AIR ADVECTION SHOULD ALLOW OVERNIGHT
LOWS TO FALL INTO THE LOWER TO MIDDLfE 40S IN THE FAR NORTH...MIDDLE TO
UPPER 40S IN REMAINDER OF MN ZONES. LOWS IN THE LOWER 50S
SHOULD REMAIN ACROSS NORTHWESTERN WISCONSIN ZONES.

THANKS TO MPX FOR EARLY LOOK AT WORK ZONES.
