   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0400 AM CDT MON AUG 03 2015

   VALID 041200Z - 051200Z

   ...SYNOPSIS...
   A WEAKENING UPPER TROUGH OVER THE NRN ROCKIES/INTERMOUNTAIN WEST AT
   THE START OF THE PERIOD WILL MOVE EWD INTO THE PLAINS DURING THE
   DAY...AS A DEEP UPPER TROUGH CENTERED OVER BRITISH COLUMBIA
   CONTINUES BUILDING INTO THE PACIFIC NORTHWEST. A SHORTWAVE TROUGH
   OVER THE ERN PACIFIC IS EXPECTED TO EJECT NEWD INTO CNTRL/NRN CA AS
   IT BEGINS TO FEEL THE INFLUENCE OF THE DEEP TROUGH TO THE
   NORTH...WHILE AN UPPER RIDGE CONTINUES TO REBUILD OVER THE DESERT
   SOUTHWEST.

   ...NRN CA/SRN ORE NEWD INTO WRN MT...
   LARGE-SCALE ASCENT /FROM A COMBINATION OF THE DEEP TROUGH OVER BC
   AND THE SHORTWAVE MOVING INTO CNTRL/NRN CA/ AND LINGERING
   INSTABILITY WILL AGAIN SUPPORT A THREAT OF ISOLATED TO WIDELY
   SCATTERED TSTMS FROM NRN CA/SRN ORE NEWD INTO WRN MT. WHILE SOME
   LOW-LEVEL COOLING IS EXPECTED...DECREASING THE POTENTIAL FOR
   EVAPORATION...SOME DRYING IS ALSO EXPECTED IN THE WAKE OF THE TROUGH
   MOVING INTO THE PLAINS...RESULTING IN PW VALUES GENERALLY IN THE 0.5
   - 0.75 INCH RANGE. THIS WILL SUPPORT A MIX OF WET/DRY TSTM MODES
   THAT WILL POSE A RISK OF IGNITION GIVEN THE PRESENCE OF VERY DRY
   FUELS.

   ...COLUMBIA RIVER BASIN EWD INTO NRN ID PANHANDLE/NWRN MT...
   MODESTLY ENHANCED LOW-LEVEL WLY FLOW AND RH VALUES IN THE 10-20
   PERCENT RANGE WILL AGAIN SUPPORT A THREAT OF ELEVATED FIRE WEATHER
   CONDITIONS ACROSS THE ERN SLOPES OF THE CASCADES INTO PORTIONS OF
   THE COLUMBIA RIVER VALLEY. THERE IS SOME POTENTIAL FOR ELEVATED
   CONDITIONS TO EXTEND EWD INTO NWRN MT...BUT GIVEN UNCERTAINTY
   REGARDING THE STRENGTH OF LOW-LEVEL FLOW WITH ERN EXTENT...THE
   ELEVATED DELINEATION HAS BEEN CONFINED TO THE COLUMBIA RIVER BASIN
   AREA.
