   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0408 AM CDT WED JUN 15 2005
   
   VALID 151200Z - 161200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UNSEASONABLY STRONG UPPER TROUGH WILL APPROACH THE WEST COAST
   LATE IN THE PERIOD. DOWNSTREAM OF THIS TROUGH...UPPER RIDGING WILL
   GRADUALLY BUILD EWD INTO THE PLAINS STATES. VERY WARM TEMPERATURES
   WILL OCCUR OVER THE SRN THIRD OF THE NATION WITH TEMPERATURES 5-10
   DEG ABOVE NORMAL. RH READINGS WILL BE LOW AS A RESULT OVER THE SWRN
   STATES AND GREAT BASIN. THE LATE TIMING OF AN APPROACHING STRONG
   TROUGH INTO THE WEST COAST WILL PRECLUDE A CRITICAL FIRE WEATHER
   THREAT OVER THE GREAT BASIN/SWRN STATES TODAY. ELSEWHERE...MID LEVEL
   MOISTURE WILL INTERACT WITH A LEAD SHORTWAVE TROUGH TO AID IN
   ISOLATED-SCT DRY TSTMS OVER PORTIONS OF THE SRN/CENTRAL ROCKIES.
   
   ...GREAT BASIN/SWRN STATES...
   SUSTAINED SWLY WINDS MAY BRIEFLY EXCEED 20 MPH OVER THE REGION
   DURING THE AFTERNOON HOURS TODAY AS MID LEVEL FLOW GRADUALLY
   STRENGTHENS AND STEEP LAPSE RATES EXIST BENEATH THE INCREASING MID
   LEVEL FLOW. VERY WARM TEMPERATURES WILL AID IN MIN RH READINGS
   FALLING TO BETWEEN 6-10 PERCENT.
   
   ...SRN/CENTRAL ROCKIES...
   MID LVL MOISTURE STREAMING NWD OVER THE SRN ROCKIES WILL INTERACT
   WITH SRN STREAM SHORTWAVE TROUGH.  AS A RESULT..ISO-SCT TSTMS WILL
   DEVELOP OVER MUCH OF NM...ERN AZ NWD INTO ERN UT AND WRN CO. FCST
   SOUNDINGS SUGGEST THAT A SUFFICIENTLY DEEP DRY SUB-CLOUD LAYER WILL
   EXIST THAT LITTLE TO NO PRECIPITATION WILL REACH THE SFC.
   HOWEVER...OVERALL COVERAGE OF DRY-TSTMS IS NOT EXPECTED TO BE
   SUFFICIENT FOR A CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0409 AM CDT WED JUN 15 2005
   
   VALID 161200Z - 171200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE GREAT
   BASIN/SOUTHWEST...
   
   ...SYNOPSIS...
   STRONG UPPER TROUGH WILL CONTINUE TO DIG INTO THE WRN STATES THROUGH
   THE PERIOD...LEADING TO INCREASING SFC WINDS OVER THE GREAT
   BASIN/SWRN STATES. COMBINED WITH MIN RH READINGS LESS THAN 15
   PERCENT...CRITICAL FIRE WEATHER CONDITIONS WILL EXIST OVER THE
   REGION DURING THE PERIOD. FARTHER EAST...UPPER RIDGING WILL REMAIN
   OVER THE PLAINS STATES...WITH TROUGHING OVER THE ERN THIRD OF THE
   NATION
   
   ...CRITICAL FIRE WEATHER AREA 1 - SRN/ERN AND PORTIONS OF CENTRAL
   NV...NWRN AZ AND WCENTRAL/SWRN UT...
   
   PRIMARY CONDITIONS: MIN RH READINGS FROM 10-15 PERCENT...SUSTAINED
   SWLY WINDS AROUND 20 MPH FOR 3-4 HRS
   
   DEEPENING UPPER TROUGH OVER THE WEST COAST WILL LEAD TO
   STRENGTHENING SFC CYCLONE OVER THE NRN GREAT BASIN. THIS COMBINED
   WITH INCREASING MID LVL WINDS WILL SUPPORT THE DEVELOPMENT OF
   MODERATE SUSTAINED SFC WINDS OVER PORTIONS OF THE REGION. DESPITE
   THE LIKELY PRESENCE OF MID/HIGH CLOUD COVER /AHEAD OF THE WEST COAST
   UPPER TROUGH/ OVERSPREADING THE AREA DURING THE AFTERNOON AIDING IN
   A FEW DEGREES OF COOLING FROM THAN DAY ONE...RH READINGS ARE STILL
   FCST TO RANGE FROM 10-15 PERCENT. BREEZY CONDITIONS WILL LIKELY
   CONTINUE WELL INTO THE OVERNIGHT HOURS IN HIGHER TERRAIN GIVEN
   STATIONARY NATURE OF THE UPPER LEVEL FEATURES. IN ADDITION
   ...ISOLATED-SCT DRY THUNDERSTORMS ARE POSSIBLE OVER NRN NV/NRN UT
   DURING THE AFTERNOON/EVENING HOURS WHERE STRONG FORCING AND MID
   LEVEL MOISTURE/INSTABILITY PLUME WILL CO-EXIST.
   
   ...CENTRAL/SRN ROCKIES...
   WEST OF THE LOW LEVEL MOISTURE OVER THE HIGH PLAINS OF ERN
   CO/NM...SUFFICIENT MID-LVL INSTABILITY WILL EXIST FOR ISOLATED TSTMS
   OVER CENTRAL CO/NM DURING THE PERIOD. ENOUGH MID LEVEL INSTABILITY
   AND SHEAR WILL EXIST THAT ISO DRY THUNDERSTORMS WILL BE POSSIBLE
   DURING THE AFTERNOON/EVENING HOURS.
