   CONCERNING...TORNADO WATCH 76...
   
   VALID 260022Z - 260115Z
   
   THE THREAT FOR TORNADOES WILL INCREASE IN SRN PORTION OF WW 76 AS
   DISCRETE TSTMS APPROACH LOW-LEVEL MOIST AXIS AND BACKED S/SSELY
   SURFACE WINDS.
   
   AS OF 0015Z...A N/S LINE OF SCATTERED DISCRETE CELLS HAD REACHED
   AROUND 25 E AUW TO 40 W OSH FROM SHAWANO TO WAUSHARA COUNTIES. THE
   MOST INTENSE SUPERCELL /WITH A HISTORY OF PRODUCING LARGE HAIL/ IS
   CURRENTLY TRACKING FROM PORTAGE COUNTY INTO WAUPACA COUNTY. AS IT
   DOES SO...THIS STORM WILL ENCOUNTER A MORE FAVORABLE AIR MASS FOR
   TORNADOES. LATEST SURFACE ANALYSES INDICATE A MOIST AXIS OF SURFACE
   DEW POINTS IN THE UPPER 50S TO AROUND 60 CONTINUES TO BE MAINTAINED
   ACROSS ERN WI. ASSOCIATED BACKED SURFACE WINDS FROM THE S/SSE WILL
   PROVIDE A FAVORABLE LOW-LEVEL SHEAR ENVIRONMENT AS EVIDENCED BY 00Z
   GRB SOUNDING. AS SUCH...TORNADIC POTENTIAL WILL LIKELY INCREASE
   THROUGH AT LEAST 02Z.
