   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0409 AM CDT SAT APR 28 2007
   
   VALID 281200Z - 291200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL/SRN GA AND NRN
   FL...
   
   ...SYNOPSIS...
   A BROAD UPPER RIDGE WILL RESIDE OVER THE WRN CONUS SUPPORTING WELL
   ABOVE NORMAL TEMPERATURES TO MUCH OF THIS PART OF THE NATION TODAY.
   MEANWHILE...SFC COLD FRONT ASSOCIATED WITH BROAD UPPER TROUGH
   LOCATED OVER THE ERN STATES WILL USHER IN A DRIER AIRMASS OVER THE
   SERN STATES. MODERATE LOW LEVEL WINDS COMBINED WITH VERY LOW RH
   READINGS AND ONGOING DROUGHT CONDITIONS WILL SUPPORT A CRITICAL FIRE
   WEATHER THREAT OVER SRN/CENTRAL GA AND NRN FL. ELSEWHERE AN UPPER
   TROUGH WILL GRAZE THE PAC NW/NRN ROCKIES SUPPORTING AN INCREASE IN
   LOW-MID LEVEL WINDS AND NEAR CRITICAL FIRE WEATHER CONDITIONS. MID
   LEVEL MOISTURE AND LIFT ASSOCIATED WITH AN UPPER LOW CENTERED OVER
   SONORA MX ALONG WITH WARM/DRY AND DEEPLY MIXED BOUNDARY LAYER WILL
   SUPPORT THE THREAT FOR ISOLATED DRY TSTMS OVER PORTIONS OF ERN/SRN
   AZ AND WRN NM.
   
   ...CRITICAL FIRE WEATHER AREA - CENTRAL/SRN GA AND NRN FL...
   
   PRIMARY CONDITIONS: SUSTAINED NWLY WINDS FROM 10-15 WITH GUSTS TO 20
   MPH...MIN RH READINGS FROM 20-30 PERCENT...LONG TERM DROUGHT
   
   IN THE WAKE OF A SFC COLD FRONT...DEWPTS HAVE FALLEN INTO THE
   40S/LOWER 50S OVER MOST OF SRN/CENTRAL GA. THIS TREND WILL CONTINUE
   INTO NRN/CENTRAL FL THROUGH THE REMAINDER OF THE MORNING. DEEPER
   MIXING COMMENCING BY LATE MORNING WILL SUPPORT AN INCREASE IN NWLY
   WINDS TO BETWEEN 10-15 MPH WITH GUSTS TO AROUND 20 MPH /STRONGER
   THAN CURRENT MODEL FCSTS/ GIVEN THE PRESENCE OF 25-30 KT WINDS NOTED
   ON REGIONAL RADAR DERIVED WIND WINDS EARLY THIS MORNING THAT WILL
   MIX TO THE SFC BY EARLY AFTERNOON. AS TEMPERATURES WARM INTO THE
   LOWER TO MID 80S /NEAR NORMAL/ MIN RH READINGS WILL FALL INTO THE
   20-30 PERCENT RANGE. THE COMBINATION OF THESE PARAMETERS WILL
   SUPPORT A CRITICAL FIRE WEATHER THREAT.
   
   ...SRN/ERN AZ AND WRN NM...
   ESELY MID LEVEL FLOW AROUND AN UPPER LOW CENTERED OVER THE GULF OF
   CALIFORNIA WILL SUPPORT AN INCREASE IN MID LEVEL MOISTURE OVER THE
   AREA TODAY. GREATER LOW LEVEL MOISTURE WILL REMAIN EAST OF THE
   AREA...ALLOWING FOR A DEEPLY MIXED BOUNDARY LAYER BENEATH THIS MID
   LEVEL MOIST LAYER. THE RESULT WILL BE AN ENVIRONMENT SUPPORTIVE OF
   MAINLY DRY TSTMS. THE GREATER TSTM COVERAGE IS EXPECTED TO REMAIN
   ALONG AND SOUTH OF THE MX BORDER AND AREAS WHERE LOW LEVEL MOISTURE
   IS HIGHER.
   
   ...MT...
   INCREASING MID LEVEL SWLY FLOW AND A DEEPLY MIXED BOUNDARY LAYER
   WILL SUPPORT SWLY WINDS FROM 15-20 MPH. MILD TEMPERATURES IN THE
   UPPER 70S/LOWER 80S WILL SUPPORT MIN RH READINGS FROM 15-20 PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0410 AM CDT SAT APR 28 2007
   
   VALID 291200Z - 301200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A BROAD UPPER RIDGE WILL REMAIN CENTERED OVER THE ROCKIES WHILE
   SHIFTING IT/S INFLUENCE INTO THE PLAINS TOMORROW. THIS WILL SUPPORT
   A WARMING TREND ACROSS THE PLAINS ALONG WITH AN INCREASE IN SFC
   WINDS. UPPER TROUGHING WILL GRADUALLY SHIFT AWAY FROM THE ERN
   CONUS...SUPPORTING A DECREASE IN SUSTAINED WINDS OVER THE SERN
   STATES. MEANWHILE...AN UPPER LOW OVER NRN MX WILL CONTINUE TO
   SUPPORT SCT CONVECTION OVER THE SWRN STATES.
   
   ...SERN STATES/FL...
   LOW RH READINGS WILL DEVELOP AGAIN TOMORROW AS TEMPERATURES WARM
   INTO THE 80S AND DWPTS REMAIN IN THE 40S/50S. UNLIKE TODAY...LOWER
   WIND SPEEDS /SUSTAINED LESS THAN 10 MPH/ WILL PRECLUDE A CRITICAL
   FIRE WEATHER OUTLOOK AREA. 
   
   ...NRN GREAT BASIN...
   AS A TROUGH DIGS INTO THE PAC NW...SWLY SFC WINDS WILL INCREASE OVER
   THE NRN GREAT BASIN AND NRN ROCKIES AHEAD OF A COLD FRONT. MIN RH
   READINGS WILL REMAIN LESS THAN 15 PERCENT AS THE SFC THERMAL RIDGE
   MOVES OVER THE AREA AND TEMPERATURES WILL BE WELL ABOVE NORMAL. LACK
   OF DROUGHT CONDITIONS AND ANNUAL GREEN-UP WILL PRECLUDE A CRITICAL
   FIRE WEATHER OUTLOOK AREA. 
   
   ...NRN MN/WI...
   AHEAD OF A NRN STREAM TROUGH TOPPING THE UPPER RIDGE...A COLD FRONT
   WILL SHIFT SEWD THROUGH MN LATE IN THE DAY. AHEAD OF THE FRONT...WLY
   WINDS WILL INCREASE TO BETWEEN 15-25 MPH. LOW RH READINGS FROM 20-30
   PERCENT WILL ALSO BE PRESENT.  IN THE WAKE OF THE FRONT...WINDS WILL
   SHIFT TO A NW DIRECTION AND INCREASE. BUT COLDER AIR LAGGING THE
   FRONT WILL LIKELY AID IN MIN RH READINGS NEAR 25 PERCENT FOR SEVERAL
   HRS AFTER THE PASSAGE OF THE FRONT. THE AREA WILL BE MONITORED FOR A
   POSSIBLE CRITICAL FIRE WEATHER AREA IN THE NEXT DAY 1 OUTLOOK.
