   NO CHANGES HAVE BEEN MADE TO THE ONGOING FORECAST.

   ..COHEN.. 09/01/2015

   .PREV DISCUSSION... /ISSUED 0300 AM CDT TUE SEP 01 2015/

   ...SYNOPSIS...
   WITHIN A BROADER UPPER LEVEL CYCLONIC CIRCULATION OVER MUCH OF WRN
   CANADA...A SHORTWAVE TROUGH WILL MOVE SEWD FROM OFF THE BRITISH
   COLUMBIA COAST TO THE PACIFIC NORTHWEST THROUGH THE PERIOD. SWLY
   MID-LEVEL FLOW WILL CONTINUE OVER PORTIONS OF THE GREAT BASIN AND
   NRN ROCKIES BETWEEN THIS TROUGH AND UPPER RIDGING THAT WILL REMAIN
   OVER MUCH OF THE DESERT SOUTHWEST AND CNTRL/ERN CONUS. SOME OF THE
   ENHANCED WINDS AT MID LEVELS COULD BE PROMOTED TO THE SFC THIS
   AFTERNOON ACROSS PORTIONS OF THE PACIFIC NORTHWEST...GREAT BASIN...
   AND NRN ROCKIES WITH DIURNAL HEATING/MIXING OF THE BOUNDARY LAYER.

   ...PORTIONS OF THE NRN ROCKIES AND ADJACENT HIGH PLAINS IN N-CNTRL
   MT...
   AS DOWNSLOPE SWLY WINDS INCREASE TO 15-20 MPH FOR A FEW HOURS THIS
   AFTERNOON...WARMING/DRYING OF THE BOUNDARY LAYER SHOULD LOWER RH
   VALUES TO 15-20 PERCENT PER LATEST RAP/GFS FORECAST SOUNDINGS. IN
   THE PRESENCE OF DRY FUELS...THIS COMBINATION OF GUSTY WINDS WITH
   SUFFICIENTLY LOWERED RH VALUES SHOULD ELEVATE FIRE WEATHER CONCERNS
   ACROSS THIS REGION TODAY. THEREFORE...A SMALL ELEVATED AREA HAS BEEN
   INTRODUCED ACROSS A PORTION OF THE NRN ROCKIES AND ADJACENT HIGH
   PLAINS IN N-CNTRL MT. WEAKER FORECAST WINDS SURROUNDING THE ELEVATED
   DESIGNATION CURRENTLY PRECLUDE A LARGER FIRE WEATHER THREAT AREA.
