   NRN FRINGE OF WRN U.S. UPPER RIDGE WILL FLATTEN SLIGHTLY WITH THE

   MPH ARE EXPECTED OVER MOST OF NWRN MT. GUSTS OF 25-30 MPH WILL BE
   POSSIBLE ON THE E SLOPES.  RH VALUES ARE EXPECTED TO BOTTOM OUT IN
   THE 15-20 PERCENT RANGE.  STABLE MID LEVEL LAPSE RATES WILL HELP

   ...NWRN INTO CNTRL OK...
   VERY HOT CONDITIONS WILL PREVAIL AGAIN TODAY AS TEMPERATURES REACH
