   AREAS AFFECTED...WRN/CNTRL ND

   CONCERNING...FREEZING RAIN 

   VALID 100448Z - 100745Z

   SUMMARY...A BAND OF PRECIPITATION WILL CONTINUE NEWD FROM W-CNTRL ND
   INTO N-CNTRL ND. ADDITIONAL PRECIPITATION IS EXPECTED IN THE WAKE OF
   THIS BAND. THE ATMOSPHERIC PROFILE IS SUPPORTIVE OF FREEZING
   RAIN...WHICH MAY LAST LONGER THAN 3 HOURS AND SUPPORT ICE
   ACCUMULATIONS GREATER THAN 0.05 INCH.

   DISCUSSION...LATEST REGIONAL RADAR IMAGERY SHOWS A BAND OF
   PRECIPITATION EXTENDING ROUGHLY FROM BIS NWWD TO ISN. THERE IS SOME
   UNCERTAINTY AS TO WHEN THIS PRECIPITATION WILL BE ABLE TO OVERCOME
   THE SUBSTANTIAL DRY LAYER NOTED ON THE 00Z BIS SOUNDING AND REACH
   THE SURFACE BUT ISN HAS BEEN REPORTING FREEZING RAIN FOR ABOUT AN
   HOUR...WITH MUCH OF THE AREA BENEATH THIS BAND LIKELY NOW
   EXPERIENCING FREEZING RAIN AS WELL. THIS BAND IS EXPECTED TO
   CONTINUE NEWD WITH THE POTENTIAL FOR ADDITIONAL PRECIPITATION --
   LIKELY FREEZING RAIN -- IN ITS WAKE /PARTICULARLY ACROSS SWRN AND
   S-CNTRL ND/. AS THE BAND CONTINUES NEWD...A TRANSITION TO SLEET AND
   THEN SNOW IS EXPECTED. 

   THE COMBINATION OF PRECIPITATION WITHIN THE BAND AND THEN IN ITS
   WAKE IS EXPECTED TO RESULT IN FREEZING RAIN DURATION AT OR ABOVE 3
   HOURS WITH ICE ACCUMULATIONS OVER 0.05 INCH POSSIBLE.
