   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0227 AM CDT TUE APR 07 2009
   
   VALID 071200Z - 081200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SERN CA/SRN NV/WRN AZ...
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NWRN TX/WRN OK/ERN NM...
   ...CRITICAL FIRE WEATHER AREA FOR FLORIDA...
   
   ...SYNOPSIS...
   AN UPPER LOW OFF THE CNTRL CA COAST WILL GRADUALLY BEGIN TO SHIFT
   ONSHORE...WITH STRONG SWLY WINDS ALOFT OVERSPREADING THE SWRN
   STATES. IN RESPONSE...A SURFACE LOW WILL FORM INVOF THE GREAT
   BASIN...WHILE A COLD FRONT MOVES THROUGH WRN NV/CNTRL CA DURING THE
   DAY...THEN THROUGH NV AND SRN CA REACHING THE UT AND AZ BORDERS
   EARLY WED MORNING. AHEAD OF THE FRONT AND PACIFIC MOISTURE...HOT AND
   DRY CONDITIONS WILL PERSIST ACROSS THE SWRN STATES...WITH STRONG SLY
   WINDS AND HIGHER GUSTS OVER SERN CA/SRN NV AND WRN AZ.
   
   THE CA UPPER LOW WILL ALLOW STRONG UPPER RIDGING OVER THE
   INTERMOUNTAIN WEST TO DEAMPLIFY AND SHIFT EWD...ALTHOUGH MUCH OF THE
   WEST BENEATH THE RIDGE WILL STILL EXPERIENCE WELL ABOVE NORMAL
   TEMPERATURES. 
   
   MEANWHILE...NWLY FLOW ALOFT AHEAD OF THE UPPER RIDGE WILL INDUCE A
   WEAK SURFACE LOW NEAR THE TX/OK PANHANDLES. STRONG WINDS WILL ALIGN
   WITH EXTREMELY LOW RHS FOR A CRITICAL FIRE THREAT...MAINLY NEAR THE
   SURFACE LOW. LITTLE RH RECOVERY CAN BE EXPECTED OVERNIGHT IN THESE
   AREAS. ELSEWHERE IN THE SRN PLAINS...SURFACE WINDS WILL SHIFT TO SLY
   ALLOWING WARMER...BUT STILL DRY...CONDITIONS.
   
   FURTHER E...THE ERN STATES WILL BE LARGELY DOMINATED BY AN UPPER
   TROUGH. STRONG NWLY FLOW ALOFT WILL BRING COOLER AND MUCH DRIER AIR
   TO THE SERN STATES. CRITICAL CONDITIONS WILL BE LIKELY ACROSS SRN GA
   AND ALL OF FL AS STRONG WINDS ALIGN WITH LOW RHS.
   
   ...CRITICAL FIRE WEATHER AREA - SERN CA/SRN NV/WRN AZ...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...ANTECEDENT DRYNESS
   
   AN UPPER LOW WILL MOVE TOWARDS THE CNTRL CA COAST...OVERSPREADING
   STRONG SWLY WINDS ALOFT ACROSS MUCH OF THE SWRN STATES. THIS WILL
   INDUCE A SURFACE LOW OVER THE NRN GREAT BASIN...AND ALLOW STRONG SLY
   WINDS AT THE SURFACE AS A COLD FRONT APPROACHES. HOT AND DRY
   CONDITIONS...WITH TEMPERATURES IN THE 90S ACROSS LOWER VALLEYS AND
   70S FURTHER N AND IN HIGHER TERRAIN WILL NOT ONLY ALLOW RHS TO FALL
   INTO THE SINGLE DIGITS TO LOWER TEENS...BUT ALLOW STRONGER GUSTS TO
   MIX TO THE SURFACE AS WELL. SUSTAINED SPEEDS NEAR 20 TO 25 MPH WITH
   GUSTS TO 40 MPH CAN BE EXPECTED.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF NWRN TX/WRN OK/ERN NM...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH
   
   A WEAK SURFACE LOW WILL FORM INVOF THE TX/OK PANHANDLES IN RESPONSE
   TO NWLY FLOW ALOFT. AN EXTREMELY DRY AIRMASS IS ALREADY IN
   PLACE...WITH PWATS NEAR 20% OF CLIMATOLOGICAL NORMALS...PER 00Z
   SOUNDING DATA. ALREADY LOW RHS WILL MAKE LITTLE RECOVERY THIS
   MORNING...AND WILL QUICKLY FALL INTO SINGLE DIGITS AND TEENS AS
   TEMPERATURES WARM INTO THE 70S. SURFACE WINDS NEAR 20 TO 25 MPH WITH
    OCCASIONAL GUSTS TO 35 MPH CAN BE EXPECTED. LITTLE RH RECOVERY WILL
   OCCUR OVERNIGHT...ALTHOUGH WINDS WILL DECREASE POST SUNSET.
   
   ...CRITICAL FIRE WEATHER AREA - SRN GA/FLORIDA...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...HIGH KBDI IN CNTRL/SRN
   FL
   
   COOL/DRY CONTINENTAL AIR WILL CONTINUE TO BE ADVECTED SEWD AS A
   LARGE SCALE UPPER TROUGH DOMINATES THE ERN STATES. ALTHOUGH
   TEMPERATURES WILL BE SOMEWHAT COOL...MID 50S TO THE N...AND MID 60S
   TO THE S...A MUCH DRIER AIRMASS COMPARED TO YESTERDAY WILL LEAD TO
   CRITICALLY LOW RHS. AREAS TO THE N WILL FALL INTO THE LOW TO MID
   20S...WHILE FURTHER S WILL FALL INTO THE LOW TO MID 30S. A STRONG
   PRESSURE GRADIENT BEHIND AN EXITING TROUGH TO THE E WILL LEAD TO
   STRONG WINDS ACROSS SRN GA AND FLORIDA...WITH SUSTAINED SPEEDS NEAR
   20 TO 25 MPH AND GUSTS TO 35 MPH. ALTHOUGH AREAS TO THE N HAVE
   RECEIVED SIGNIFICANT RAINFALL RECENTLY...DRY CONDITIONS YESTERDAY
   AND STRONG WINDS WILL ACT TO DRY FUELS. FURTHERMORE...CNTRL AND SRN
   FL REMAIN DRY...WITH HIGH KBDI VALUES...AND GIVEN AFOREMENTIONED
   WINDS/RH...DANGEROUS FIRE CONDITIONS WILL EXIST TODAY.
   
   ...MUCH OF THE SOUTH...
   FOLLOWING THE RECENT FRONTAL PASSAGE...AN EXTREMELY DRY AIRMASS HAS
   BEEN DOMINATING THE SOUTH. LITTLE GULF MOISTURE WILL RETURN TO THE
   SOUTHERN PLAINS DESPITE SURFACE WINDS SHIFTING TO SLY. RHS OF LOWER
   20S WILL BE EXPERIENCED AS FAR S AS SRN TX...AND DESPITE LIGHT WINDS
   THIS WILL POSE A FIRE HAZARD IN AREAS PLAGUED BY DROUGHT. FURTHER E
   ACROSS LA/MS/AL...TEMPERATURES WILL BE COOLER AND RHS WILL BE
   SOMEWHAT HIGHER...BUT WINDS WILL BE STRONGER AND FROM THE NORTHWEST.
   IN GA/SC AND NC...WINDS WILL BE STRONG AND FROM THE W...ALTHOUGH
   TEMPERATURES WILL BE COOLER AND RECENT RAINFALL SHOULD HELP TO
   SOMEWHAT MITIGATE THE OVERALL THREAT. REGARDLESS...FIRE CREWS SHOULD
   BE AWARE THAT APART FROM THE CRITICAL AREAS WHERE A HIGHER THREAT
   EXISTS COMPARED TO SURROUNDING AREAS...A FIRE THREAT STILL EXISTS
   ACROSS NEARLY ALL OF THE SRN STATES TODAY.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0313 AM CDT TUE APR 07 2009
   
   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SERN AZ...SRN/ERN NM...WRN TX...
   
   ...SYNOPSIS...
   THE UPPER LOW CURRENTLY APPROACHING THE CNTRL CA COAST WILL PROGRESS
   EWD AS AN OPEN WAVE...BECOMING ORIENTED OVER THE ROCKIES BY EARLY
   THU MORNING. STRONG SWLY FLOW ALOFT WILL OVERSPREAD THE SWRN
   STATES...INDUCING SURFACE CYCLOGENESIS NEAR THE SERN CO/NERN NM
   BORDERS. STRONG WINDS WILL ALIGN WITH LOW RHS ACROSS SRN
   AZ...SRN/ERN NM...AND WRN TX. 
   
   FURTHER E...AN UPPER LONG WAVE TROUGH WILL DOMINATE THE ERN
   STATES...WITH COOL/DRY CONTINENTAL FLOW CONTINUING. AT THE
   SURFACE...HIGH PRESSURE WILL SETTLE OVER THE OPEN WATERS E OF THE
   SRN FL PENINSULA...WITH A LIGHTER PRESSURE GRADIENT AND ASSOCIATED
   SURFACE WINDS ACROSS THE SERN STATES COMPARED TO D1. SURFACE WINDS
   WILL SHIFT TO SWLY AROUND THE PERIPHERY OF THE HIGH...LEADING TO
   WARMER TEMPERATURES...ALTHOUGH RHS WILL REMAIN LOW.
   
   ...CRITICAL FIRE WEATHER AREA - SERN AZ...SRN/ERN NM...WRN TX...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...DROUGHT
   
   A SURFACE LOW WILL DEVELOP INVOF THE SERN CO/NERN NM BORDERS IN
   RESPONSE TO AN APPROACHING UPPER LOW TO THE W. SUSTAINED WINDS NEAR
   25 TO 35 MPH WITH GUSTS TO 50 MPH CAN BE EXPECTED AS THE PRESSURE
   GRADIENT INCREASES AND WARMING TEMPERATURES ALLOW STRONG GUSTS TO
   MIX TO THE SURFACE. AN EXTREMELY DRY AIRMASS WILL REMAIN OVER THE
   AREA...AND RHS IN THE SINGLE DIGITS AND LOWER TEENS CAN BE EXPECTED
   AS TEMPERATURES WARM INTO THE 70S AND LOWER 80S. LITTLE RH RECOVERY
   WILL OCCUR OVERNIGHT.
   
   ...FLORIDA...
   WINDS WILL SHIFT TO SWLY ACROSS MOST OF FL WITH THE EXCEPTION OF THE
   SRN PENINSULA...WHERE LOCAL SEABREEZE EFFECTS WILL CHANGE THE WIND
   DIRECTION ALONG THE COASTS. WARMER TEMPERATURES WILL RETURN...BUT
   LITTLE GULF/ATLANTIC MOISTURE WILL BE AVAILABLE TO PROVIDE MUCH
   IMPROVEMENT TO DEW POINTS/AFTERNOON RHS. ALTHOUGH A WEAKER PRESSURE
   GRADIENT WILL LEAD TO LIGHTER WINDS COMPARED TO D1...RHS WILL STILL
   BE LOW...WITH LOW TO MID 20S ACROSS N AND CNTRL FL...AND LOWER 30S
   IN THE S. AT THE MOMENT WINDS APPEAR TO BE MARGINAL...HOWEVER IT IS
   POSSIBLE THAT A CRITICAL WILL NEED TO BE ADDED IN TOMORROWS
   FORECAST...MAINLY FOR THE FL PANHANDLE AND THE SUWANNEE
   VALLEY...WHERE STRONGER WINDS AROUND THE PERIPHERY OF THE HIGH AND
   AHEAD OF A LOW TO THE W MAY BE ACHIEVED.
