   NWS STORM PREDICTION CENTER NORMAN OK
   0332 AM CDT SUN MAR 25 2007
   
   VALID 251200Z - 261200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL/SRN FLA...
   
   ...SYNOPSIS...
   A SPLIT FLOW PATTERN AT UPPER LEVELS WILL CONTINUE TODAY ACROSS THE
   CONUS...WITH THE BEGINNING OF A TRANSITION TO A WRN TROUGH/ERN RIDGE
   PATTERN. IN THE NRN STREAM...A PROGRESSIVE UPPER TROUGH WILL PRODUCE
   SCT PRECIPITATION OVER THE UPPER MIDWEST/GREAT LAKES. IN THE SRN
   STREAM...AN UPPER LOW WILL SLOWLY PROGRESS EWD THROUGH NRN MEXICO.
   AHEAD OF THIS UPPER LOW...SCT PRECIPITATION WILL OCCUR OVER THE SRN
   PLAINS. DOWNSTREAM OF THIS SYSTEM...UPPER RIDGING CENTERED OVER THE
   SERN STATES WILL PROVIDE FOR ABOVE-WELL ABOVE NORMAL TEMPERATURES TO
   MUCH OF THE NATION EAST OF THE ROCKIES. WHERE LOW RH READINGS...LONG
   TERM DROUGHT CONDITIONS AND MODERATE WINDS EXIST OVER PORTIONS OF
   FLA...A CRITICAL FIRE WEATHER THREAT WILL EXIST. ELSEWHERE...UPPER
   TROUGHING WILL BEGIN TO AMPLIFY OVER THE NERN PACIFIC SUPPORTING SCT
   PRECIPITATION OVER THE PAC NW.
   
   ...CRITICAL FIRE WEATHER AREA - THE WRN HALF OF SRN/CENTRAL FLA...
   
   PRIMARY CONDITIONS: SUSTAINED NELY WINDS AROUND 15 MPH WITH GUSTS UP
   TO 20 MPH...MIN RH READINGS FROM 25-35 PERCENT...LONG TERM DROUGHT
   
   A MODERATE PRESSURE GRADIENT WILL EXIST BETWEEN A BROAD AREA OF HIGH
   PRESSURE OVER THE SERN STATES AND LOWER PRESSURE OVER THE NRN
   CARIBBEAN. SIMILAR TO YESTERDAY...SUSTAINED NELY WINDS WILL BE
   AROUND 15 MPH DURING THE AFTERNOON. STEEP LOW LEVEL LAPSE RATES WILL
   SUPPORT AFTERNOON GUSTS AROUND 20 MPH. ALTHOUGH WIND TRAJECTORIES
   WILL SUPPORT HIGHER DEWPTS ALONG THE EAST COAST A COMBINATION OF LOW
   LEVEL MIXING...DRY GROUND CONDITIONS AND ABOVE NORMAL TEMPERATURES
   WILL SUPPORT MIN RH READINGS FROM 25-35 PERCENT OVER THE WRN HALF OF
   THE PENINSULA LEADING TO A CRITICAL FIRE WEATHER THREAT.
   
   ...THE REST OF FLA...SERN STATES/SRN APPALACHIANS...
   UNLIKE SRN/CENTRAL FLA...SUSTAINED WINDS WILL BE LIGHTER /AROUND 10
   MPH/. LOW RH READINGS /20-30 PERCENT/ DUE TO ABOVE NORMAL
   TEMPERATURES IN THE 70S/80S AND DEWPTS FROM 40-55 F WILL SUPPORT
   VERY HIGH FIRE DANGERS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0335 AM CDT SUN MAR 25 2007
   
   VALID 261200Z - 271200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE SRN GREAT BASIN AND
   PORTIONS OF THE LOWER CO RIVER VALLEY...
   
   ...SYNOPSIS...
   STRONG UPPER TROUGHING WILL OCCUR ALONG THE WEST COAST THROUGH
   TOMORROW. IN RESPONSE TO THIS DEEPENING SYSTEM...AN AREA OF SFC LOW
   PRESSURE WILL DEEPEN OVER THE GREAT BASIN. SOUTH OF THIS SFC
   LOW...MODERATE WINDS AND LOW RH READINGS WILL COMBINE TO PRODUCE A
   CRITICAL FIRE WEATHER THREAT OVER THE SRN GREAT BASIN AND LOWER CO
   RIVER VALLEY. ELSEWHERE ACROSS THE NATION...AN UPPER SYSTEM WILL
   MOVE OUT OF MEXICO INTO TX AIDING IN SCT PRECIPITATION TO MUCH OF
   THE SRN PLAINS. DOWNSTREAM OF THIS SYSTEM...UPPER RIDGING WILL
   SUPPORT CONTINUED DRY CONDITIONS OVER THE SERN STATES. CRITICAL
   CONDITIONS MAY DEVELOP AGAIN DURING THE AFTERNOON HRS OVER PORTIONS
   OF CENTRAL/SRN FL WHERE LOW RH READINGS WILL EXIST.
   
   ...CRITICAL FIRE WEATHER AREA - FOR PORTIONS OF CENTRAL/SRN
   NV...SERN CA AND FAR WRN AZ...
   
   PRIMARY CONDITIONS: SUSTAINED SSWLY WINDS FROM 20-30 MPH WITH GUSTS
   OVER 35 MPH...MIN RH READINGS AROUND 15 PERCENT...LONG TERM DROUGHT
   CONDITIONS
   
   AHEAD OF A STRONG/DEEPENING UPPER TROUGH OFF THE CA
   COAST...INCREASING MID LEVEL WIND FIELDS OVER THE SIERRA NEVADA WILL
   AID IN THE STRENGTHENING OF A SFC LOW PRESSURE AREA OVER NRN/CENTRAL
   NV. AN INCREASING PRESSURE GRADIENT COMBINED WITH STEEP LOW-MID
   LEVEL LAPSE  AND STRONG MID LEVEL WINDS FIELDS WILL SUPPORT WINDS
   INCREASING TO BETWEEN 20-30 MPH WITH HIGHER GUSTS DURING THE
   AFTERNOON HOURS. ALTHOUGH HIGH CLOUD COVER WILL OVERSPREAD MUCH OF
   THE AREA...NEAR TO ABOVE NORMAL TEMPERATURES IN THE 70S-MID 80S IN
   LOWER ELEVATIONS AND SEASONABLY LOW DEWPTS 20S IN CENTRAL/SRN NV TO
   THE 30S IN THE LOW CO RIVER VALLEY WILL SUPPORT MIN RH READINGS
   AROUND 15 PERCENT. ALTHOUGH RH READINGS WILL BE RIGHT AT CRITICAL
   THRESHOLDS...THE STRENGTH OF THE WIND FIELDS SUPPORT A CRITICAL FIRE
   WEATHER THREAT.
   
   ...CENTRAL/SRN FLA...
   A REINFORCING SURGE OF SFC HIGH PRESSURE FROM THE MID-ATLANTIC
   SHOULD SUPPORT ANOTHER DAY OF SUSTAINED ENELY WINDS AROUND 15 MPH
   WITH GUSTS TO 20 MPH. AFTERNOON RH READINGS ARE AGAIN EXPECTED TO
   FALL TO AROUND 30 PERCENT. AREA WILL BE MONITORED FOR AN UPGRADE TO
   CRITICAL IN A LATER OUTLOOK.
