   DAY 1 FIRE WEATHER OUTLOOK

   VALID 161200Z - 171200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NRN CA/ORE...
   
   ...SYNOPSIS...
   AN UPPER TROUGH OFF THE CA COAST WILL PROGRESS EWD INTO NRN CA/SRN
   ORE THROUGH THE PERIOD. THIS SYSTEM WILL INTERACT WITH MID LEVEL
   MOISTURE AND A VERY DRY BOUNDARY LAYER TO SUPPORT SCT DRY TSTMS OVER
   PORTIONS OF THE CASCADES/SIERRA NEVADA MTNS. IN ADDITION...A HOT/DRY
   AIRMASS WILL LEAD TO CRITICAL FIRE WEATHER CONDITIONS OVER THIS
   REGION. ISOLATED DRY TSTMS WILL ALSO BE POSSIBLE OVER PORTIONS OF
   THE SRN GREAT BASIN. OTHERWISE...A LARGE AREA OF HIGH PRESSURE OVER
   MUCH OF THE NATION EAST OF THE ROCKIES WILL SUPPORT DRY
   CONDITIONS...BUT LIGHT WINDS WILL PRECLUDE ANY CRITICAL FIRE WEATHER
   THREAT.
   
   ...CRITICAL FIRE WEATHER AREA - NRN CA....SRN ORE MTNS/VALLEYS...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS...LOW RH READINGS FROM 10-15
   PERCENT
   
   AN UPPER TROUGH OFF THE NRN CA COAST WILL MOVE SLOWLY EWD
   TODAY...BEFORE LIFTING NEWD TONIGHT /AROUND AN UPPER RIDGE CENTERED
   OVER THE ROCKIES/. AHEAD OF THIS SYSTEM...MID LEVEL MOISTURE WILL
   COMBINE WITH INCREASING LIFT/DESTABILIZATION TO SUPPORT SCT TSTM
   DEVELOPMENT /MAINLY OVER THE NRN SIERRA/SRN ORE CASCADE MTNS/. A
   VERY WARM/DRY BOUNDARY LAYER BENEATH THIS LAYER WILL SUPPORT MAINLY
   DRY TSTMS WITH LITTLE RAINFALL AND GUSTY/ERRATIC WINDS. TSTMS ARE
   EXPECTED TO MOVE NWD THROUGH THE ORE CASCADES/ADJACENT VALLEYS
   OVERNIGHT AS THE UPPER TROUGH MOVES INTO NRN CA.
   
   ...PAC NW...
   OUTSIDE OF THE CRITICAL OUTLOOK AREA...VERY DRY/WARM TEMPERATURES
   /OWING TO THE PRESENCE OF AN UPPER RIDGE IN CLOSE PROXIMITY/ WILL
   SUPPORT A VERY WARM/DRY BOUNDARY LAYER. FORECAST SOUNDINGS INDICATE
   WIDESPREAD HIGH HAINES INDICES /6/ OVER MUCH OF THE INTERIOR
   PORTIONS OF THE PAC NW. IN ADDITION...ISOLATED DRY TSTMS WILL BE
   POSSIBLE OVER PORTIONS OF THE NRN ORE CASCADES LATER TONIGHT.
   
   ...SRN GREAT BASIN...
   A PLUME OF MID LEVEL MOISTURE /NOTED ON SATELLITE IMAGERY/ WILL MOVE
   WWD ACROSS THE SRN GREAT BASIN TODAY. ISOLATED TSTMS /MAINLY DRY/
   WILL BE A RESULT OVER THE REGION DURING THE AFTERNOON HOURS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 171200Z - 181200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE NRN GREAT
   BASIN/INTERIOR PAC NW...
   
   ...SYNOPSIS...
   AHEAD OF AN UPPER SYSTEM...ANOTHER CRITICAL FIRE WEATHER THREAT WILL
   OCCUR AS SCT DRY TSTMS DEVELOP FROM PORTIONS OF THE NRN GREAT BASIN
   INTO THE INTERIOR PAC NW TOMORROW. OTHERWISE...A LARGE AREA OF HIGH
   PRESSURE AT THE SFC AND ALOFT WILL KEEP DRY CONDITIONS OVER MUCH OF
   THE ERN HALF OF THE NATION...WITH NO OTHER CRITICAL FIRE WEATHER
   THREAT AREAS ANTICIPATED.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF THE NRN GREAT
   BASIN/INTERIOR PAC NW...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   ASSOCIATED WITH AN UPPER TROUGH MOVING THROUGH NRN CA/SRN ORE AT THE
   START OF THE PERIOD...MODEST FORCING COMBINED WITH MID LEVEL
   MOISTURE/INSTABILITY WILL SUPPORT THE DEVELOPMENT OF HIGH BASED
   CONVECTION FROM PORTIONS OF ERN WA SWD INTO NRN NV. DRY/WARM
   BOUNDARY LAYER WILL SUPPORT MAINLY DRY TSTMS WITH GUSTY/ERRATIC
   WINDS.
   
   ...WRN GREAT BASIN/SIERRA NEVADA...
   IN THE WAKE OF AN UPPER TROUGH...MODEST SWLY WINDS /15-20 MPH/ WILL
   DEVELOP OVER THE NRN SIERRA NEVADA/WRN GREAT BASIN TOMORROW. THESE
   WINDS WILL COMBINE WITH LOW RH READINGS /10-15 PERCENT/ TO PRODUCE
   NEAR CRITICAL FIRE WEATHER CONDITIONS.
