   DAY 1 FIRE WEATHER OUTLOOK CORR 1
   NWS STORM PREDICTION CENTER NORMAN OK
   1152 AM CDT TUE APR 05 2005
   
   VALID 051200Z - 061200Z
   
   CORRECTED FOR DIRECTION OF CRITICAL LINE
   
   ...CRITICAL FIRE WEATHER AREA FOR A PART OF THE SRN PLAINS...
   
   ...SYNOPSIS...
   A STRONG SHORTWAVE TROUGH WILL EJECT EWD OUT OF THE SRN ROCKIES AND
   INTO THE PLAINS THROUGH THE PERIOD. STEEP LAPSE RATES AND STRONG MID
   LEVEL WIND FIELDS/SFC PRESSURE GRADIENT WILL ACCOMPANY THIS SYSTEM.
   ALONG WITH LOW RH READINGS...A CRITICAL FIRE WEATHER THREAT WILL BE
   PRESENT OVER PORTIONS OF THE SRN PLAINS. FARTHER EAST...A BROAD AREA
   OF SFC HIGH PRESSURE CENTERED OFF THE SE ATLANTIC COAST WILL AID IN
   LOW RH READINGS FROM 25-35 PERCENT ACROSS MUCH OF THE COUNTRY EAST
   OF THE APPALACHIANS. HOWEVER...IN THIS REGION EXPECT SUSTAINED WINDS
   TO BE LESS THAN 15 MPH PRECLUDING ANY SIGNIFICANT FIRE WEATHER
   CONCERNS.
   
   ...CRITICAL FIRE WEATHER AREA 1 - MUCH OF WRN/CENTRAL TX...SERN
   NM...AND SWRN/SCENTRAL OK...
   
   PRIMARY CONDITIONS: SUSTAINED WSWLY WINDS FROM 20-30 MPH WITH GUSTS
   OVER 40 MPH...MIN RH READINGS FROM 10-25 PERCENT
   
   AT MID/UPPER LEVELS A STRONG SHORTWAVE TROUGH WILL PROGRESS THROUGH
   THE REGION TODAY WHILE AT THE SFC A LOW PRESSURE CENTER WILL MOVE
   FROM SWRN KS INTO NERN OK. THE COMBINATION OF A STRONG PRESSURE
   GRADIENT WITH THIS SYSTEM...ALONG WITH NEARLY DRY-ADIABATIC LAPSE
   RATES FROM THE SFC TO 700 MB WILL SUPPORT STRONG WINDS ACROSS THE
   REGION. THE STRONGEST WINDS ARE FORECAST TO OCCUR ALONG THE MID
   LEVEL COLD FRONT/WIND SPEED MAX THAT WILL EXTEND FROM SWRN INTO
   CENTRAL TX DURING THE AFTERNOON. IN THIS REGION...SUSTAINED WIND
   SPEEDS FROM 25-30 MPH WITH GUSTS OVER 40 MPH ARE EXPECTED.
   ELSEWHERE...DEEP MIXING BEHIND THE DRYLINE WHICH WILL EXTEND FROM
   THE SFC LOW ALONG I-35 FROM CENTRAL OK INTO CENTRAL TX BY THE MID
   AFTERNOON WILL SUPPORT SUSTAINED WIND SPEEDS FROM 20-25 MPH WITH
   GUSTS OVER 35 MPH. IN ADDITION TO THE WINDS...LOW DEWPTS IN THE
   10S/20S COMBINED WITH TEMPERATURES IN THE 70S TO MID 80S WILL LEAD
   TO MIN RH READINGS FROM 10-25 PERCENT. LOWER TEMPERATURES IN THE 60S
   AND SLIGHTLY HIGHER DEWPTS WILL OCCUR OVER THE PANHANDLE AND NWRN OK
   BEHIND A COLD FRONT. THUS DESPITE STRONG WNWLY WINDS FROM 20-30
   MPH...A CRITICAL FIRE WEATHER THREAT IS NOT ANTICIPATED IN THIS
   AREA.

Day 2 Fire Weather Forecast graphic

   ZCZC SPCFWDDY2 ALL
   FNUS22 KWNS 050855
   
   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0355 AM CDT TUE APR 05 2005
   
   VALID 061200Z - 071200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A MID LEVEL SHORTWAVE TROUGH WILL MOVE EAST FROM THE SRN PLAINS INTO
   THE SERN STATES. AHEAD OF THIS TROUGH SCATTERED CONVECTION WILL
   OVERSPREAD MUCH OF THE LOWER MS VALLEY/SERN STATES THROUGH THE
   PERIOD...WHILE SLY FLOW INCREASES OVER THE MID-ATLANTIC. IN THE WAKE
   OF THE TROUGH SFC HIGH PRESSURE WILL BUILD SWD THROUGH THE PLAINS
   AND UPPER RIDGING WILL BUILD EWD OVER THE ROCKIES LEADING TO ABOVE
   NORMAL TEMPERATURES/LOW RH READINGS AND LIGHT WINDS ACROSS THE SWRN
   STATES/CA.
   
   ...SRN PLAINS...
   A COLD FRONT WILL MOVE SEWD INTO THE CENTRAL GULF OF MEXICO BY
   07/12Z. IN THE WAKE OF THE COLD FRONT...MODERATE NWLY WINDS FROM
   15-25 MPH WILL OCCUR OVER THE SRN PLAINS. MIN RH READINGS WILL RANGE
   FROM 30-40 PERCENT OVER MUCH OF THE LOWER PLAINS OF CENTRAL
   TX/OK...TO 20-30 PERCENT OVER MUCH OF THE SRN HIGH PLAINS/SOUTH TX.
   IN BOTH AREAS...THESE READINGS ARE ABOVE CRITICAL LEVELS.
   
   ...CAROLINAS/MID-ATLANTIC...
   LOW LEVEL SLY FLOW WILL INCREASE OVER THE MID-ATLANTIC/CAROLINAS
   DURING THE PERIOD AHEAD OF A PROGRESSIVE SHORTWAVE TROUGH. THE
   INCREASE IN SLY FLOW WILL AID IN A NWD RETURN OF LOW LEVEL MOISTURE
   THROUGH THE SERN STATES. VERTICAL MIXING AND RELATIVELY SHALLOW
   DEPTH OF MOISTURE WILL SUPPORT SLOWER INCREASE IN MOISTURE OVER THE
   MID-ATLANTIC/CAROLINAS. IN THIS AREA...DEWPTS IN THE 30S/40S ARE
   EXPECTED DURING THE AFTERNOON. HIGH TEMPERATURES IN THE 70S WILL
   LEAD TO MIN RH READINGS OF 25-35 PERCENT IN THIS AREA. SUSTAINED
   WIND SPEEDS ARE FORECAST TO BE AROUND 15 MPH PRECLUDING CRITICAL
   FIRE WEATHER CONCERNS.
