   ...NO SVR TSTM AREAS FORECAST...
   
   ...UPPER GREAT LAKES REGION...
   WATER VAPOR IMAGERY SHOWS THAT THE TAIL-END OF THE UPPER TROUGH AXIS
   IS MOVING ACROSS UPPER MI.  ASSOCIATED COLD FRONT HAD MOVED TO A 19Z
   POSITION FROM ERN LAKE SUPERIOR-NWRN WI-SWRN MN.  THE ERN PORTION OF
   THE FRONT WILL CONTINUE SEWD INTO NRN LOWER MI TONIGHT...WHILE WRN
   PORTIONS BECOME STATIONARY ACROSS SRN MN AND CNTRL WI.
   
   WARM SECTOR REMAINS CAPPED PER RUC ANALYSIS/SOUNDINGS OWING TO WARM
   H85-H7 TEMPERATURES AHEAD OF THE FRONT.  GIVEN THE STRONGEST H5
   HEIGHT FALLS ARE TRANSLATING QUICKLY ENEWD THROUGH ONTARIO...
   CONVERGENCE ALONG THE COLD FRONT WILL BE WEAKENING WITH TIME THIS
   AFTERNOON/EVENING.  THIS WILL LEAVE BOUNDARY LAYER HEATING TO BE THE
   PRIMARY MECHANISM NEEDED TO INITIATE TSTMS.  18Z RUC SUGGESTS THAT
   THE BEST CHANCE FOR THIS TO OCCUR WILL BE IN NCNTRL/NERN WI.  LATEST
   VSBL IMAGERY DOES SHOW A BOUNDARY LAYER CU FIELD VCNTY WAUSAU AND
   THERE WILL BE A LOW PROBABILITY OF TSTMS AFTER 21Z.  GIVEN 40 KTS OF
   VERTICAL SHEAR IN THE LOWEST 6KM...ONE OR TWO STRONGER TSTMS WILL BE
   POSSIBLE WITH LARGE HAIL OR DAMAGING WIND GUSTS.  
    
   ...LOWER CO RVR VLY NEWD INTO SRN UT/NRN AZ...
   GOES SOUNDER PRECIPITABLE WATER PLOTS SHOW A PLUME OF 1+ INCH VALUES
   STREAMING NEWD FROM OFF OF BAJA INTO SRN UT/NRN AZ.  DIURNALLY
   DRIVEN TSTMS HAVE BEEN DEVELOPING WITHIN THIS INSTABILITY AXIS THIS
   AFTERNOON...AUGMENTED BY H25 JETLET OF 50 KTS. THE MID-UPPER LEVEL
   SHEAR IS SOMEWHAT WEAKER THAN YESTERDAY...BUT WILL CONTINUE TO BE
   SUFFICIENT TO SUPPORT ISOLD ORGANIZED TSTMS GIVING LARGE HAIL OR
   SEVERE WIND GUSTS.  ACTIVITY WILL WEAKEN DURING THE EVENING.
