   .PREV DISCUSSION... /ISSUED 0346 AM CDT WED MAY 04 2016/

   ...SYNOPSIS...
   A TROUGH-RIDGE-TROUGH PATTERN WILL EXIST OVER THE CONUS TODAY.
   PRIMARY FOCUS FOR FIRE WEATHER CONCERNS WILL BE WITH A LARGE-SCALE
   UPPER TROUGH MOVING SLOWLY EWD FROM THE ERN PACIFIC TO THE WEST
   COAST BY LATE TONIGHT. ENHANCED MID-LEVEL WINDS ATTENDANT TO THIS
   TROUGH WILL OVERSPREAD MUCH OF THE SWRN CONUS INTO THE GREAT BASIN
   THROUGH THE PERIOD. WITH DIURNAL MIXING ALLOWING FOR MOMENTUM
   TRANSPORT OF THE THESE STRONGER WINDS ALOFT TO THE SFC...A BROAD
   AREA OF SLOWLY INCREASING SLY WINDS APPEARS LIKELY ACROSS THE SWRN
   CONUS TODAY.

   ...PORTIONS OF THE LOWER CO RIVER VALLEY AND WRN AZ...
   ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED FOR PORTIONS OF THE
   LOWER CO RIVER VALLEY AND ADJACENT WRN AZ...AS STRONG/GUSTY SLY
   WINDS OF 15-20 MPH WILL LIKELY COMBINE WITH RH VALUES BELOW 15
   PERCENT THIS AFTERNOON. LATEST FUEL GUIDANCE SUGGESTS FINE FUELS ARE
   SUFFICIENTLY DRY TO SUPPORT FIRE SPREAD. WITH STRONGER MID-LEVEL
   WINDS FORECAST TO ARRIVE LATER THIS EVENING /AFTER PEAK HEATING AND
   A MINIMUM IN RH VALUES/ CONFIDENCE IN SUSTAINED SFC WIND SPEEDS OF
   20+ MPH FOR 3 OR MORE HOURS THIS AFTERNOON REMAINS TOO LOW TO
   INTRODUCE A CRITICAL AREA.
