   DAY 1 FIRE WEATHER OUTLOOK

   VALID 071200Z - 081200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR DRY TSTMS ACROSS A LARGE PORTION
   OF THE GREAT BASIN AND CENTRAL ROCKIES...
   ...CRITICAL FIRE WEATHER AREA FOR GUSTY WINDS/LOW RH FOR THE SRN
   GREAT BASIN...
   ...CRITICAL FIRE WEATHER AREA FOR GUSTY WINDS/LOW RH FOR A PORTION
   OF THE NRN PLAINS...
   
   ...SYNOPSIS...
   A BROAD AREA OF MID LEVEL MONSOONAL MOISTURE WILL ROTATE AROUND AN
   UPPER RIDGE CENTERED OVER THE SOUTHWEST. THIS MOISTURE COMBINED WITH
   VERY WARM TEMPERATURES/LOW RH READINGS IN THE LOW LEVELS WILL
   SUPPORT SCT/NMRS DRY TSTMS OVER MUCH OF THE GREAT BASIN/CENTRAL
   ROCKIES. ON EITHER SIDE OF THE DRY TSTM THREAT...GUSTY WINDS AND LOW
   RH READINGS OVER THE SRN GREAT BASIN AND NRN PLAINS WILL LEAD TO
   OTHER CRITICAL FIRE WEATHER THREAT AREAS AS WELL. ELSEWHERE SCT
   PRECIPITATION WILL REMAIN POSSIBLE OVER MUCH OF THE SERN STATES/SRN
   PLAINS.
   
   ...CRITICAL FIRE WEATHER AREA - A PORTION OF THE CENTRAL ROCKIES AND
   A LARGE PORTION OF THE GREAT BASIN...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   AROUND AN UPPER RIDGE CENTERED OVER THE SWRN STATES...MID LEVEL
   MOISTURE /MONSOONAL/ WILL CONTINUE TO SUPPORT TSTMS FROM THE GREAT
   BASIN INTO CENTRAL ROCKIES TODAY. LAST NIGHTS SOUNDINGS INDICATE A
   CONTINUATION OF VERY DRY LOW LEVELS OVER THE AREA WHICH WILL SUPPORT
   MAINLY DRY TSTMS. FORCING AHEAD OF A SHORTWAVE TROUGH OVER NWRN
   GREAT BASIN WILL SUPPORT A GREATER COVERAGE OF DRY TSTMS OVER THE
   NRN GREAT BASIN THAN AREAS FURTHER SOUTH AND EAST.
   
   ...CRITICAL FIRE WEATHER AREA - SRN GREAT BASIN...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 15-20 MPH WITH HIGHER
   GUSTS...MIN RH READINGS AROUND 10 PERCENT
   
   NORTH OF THE CENTER OF AN UPPER RIDGE OVER AZ...BUT SOUTH OF THE
   GREATER CONCENTRATION OF MID LEVEL MOISTURE AND DRY TSTM
   THREAT...ABOVE NORMAL TEMPERATURES...STEEP LAPSE RATES FROM THE SFC
   TO 20 KFT AND LOW RH READINGS WILL SUPPORT A CRITICAL FIRE WEATHER
   THREAT. ALTHOUGH SUSTAINED WIND SPEEDS WILL REMAIN UNDER 20 MPH FOR
   MOST OF THE PERIOD...THE COMBINATION OF GUSTS OVER 20 MPH AND NEAR
   RECORD WARMTH WILL STILL SUPPORT A CRITICAL FIRE WEATHER THREAT.
   
   ...CRITICAL FIRE WEATHER AREA - A PORTION OF THE NRN PLAINS...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 15-25 MPH...MIN RH
   READINGS AROUND 10 PERCENT
   
   AHEAD OF A SHORTWAVE TROUGH AND ASSOCIATED SFC FRONT...NEAR RECORD
   WARM TEMPERATURES FROM 100-107 DEG F WILL DEVELOP OVER PORTIONS OF
   WRN NEB AND WRN/CENTRAL SD. DRY LOW LEVELS WITH DEWPTS AROUND 40 DEG
   F WILL SUPPORT MIN RH AROUND 10 PERCENT. MODERATE SWLY WINDS WILL
   DEVELOP AHEAD OF A WEAK COLD FRONT IN RESPONSE TO AN INCREASING SFC
   PRESSURE GRADIENT...WITH SUSTAINED WINDS UP TO 25 MPH. THE
   COMBINATION OF THESE CONDITIONS WILL SUPPORT A CRITICAL FIRE WEATHER
   THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0437 AM CDT SAT JUL 07 2007
   
   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE GREAT
   BASIN/CENTRAL ROCKIES...
   
   ...SYNOPSIS...
   WNWLY FLOW OVER THE NRN GREAT BASIN WILL SHIFT THE MID LEVEL
   MOISTURE SWD INTO THE CENTRAL GREAT BASIN/ROCKIES ON DAY 2. ANOTHER
   DAY OF SCT DRY TSTMS WILL RESULT OVER THIS AREA AS DRY LOW LEVELS
   EXIST BENEATH THE MID LEVEL MOISTURE. VERY DRY AND WARM CONDITIONS
   WILL REMAIN OVER MUCH OF THE REMAINDER GREAT BASIN AND SOUTHWEST
   STATES. ELSEWHERE...SCT PRECIPITATION WILL CONTINUE TO BE POSSIBLE
   OVER THE SERN STATES...AND AHEAD OF A COLD FRONT OVER THE GREAT
   LAKES/NEW ENGLAND.
   
   ...CRITICAL FIRE WEATHER AREA - A PORTION OF THE GREAT BASIN/CENTRAL
   ROCKIES...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   JUST AHEAD OF A SEWD MOVING SHORTWAVE TROUGH OVER THE ROCKIES...MID
   LEVEL MOISTURE WILL REMAIN OVER THE CENTRAL GREAT BASIN AND
   CENTRAL/SRN ROCKIES REGION. VERY DRY/WARM LOW LEVELS BELOW STEEP MID
   LEVEL LAPSE RATES/MOISTURE WILL SUPPORT DRY TSTMS DURING THE
   AFTERNOON.
   
   ...NRN CA...
   ISOLATED DRY TSTMS MAY DEVELOP OVER THE HIGHER MTNS OF NRN CA AHEAD
   OF AN UPPER LOW OFF THE CA COAST. THE LACK OF A MORE SUBSTANTIAL
   SHORTWAVE TROUGH PASSAGE AND LITTLE TO NO MONSOONAL CONNECTION WSWLY
   MID LEVEL FLOW/ SHOULD PRECLUDE A GREATER DRY TSTM THREAT.
