   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0322 AM CDT THU OCT 11 2007
   
   VALID 111200Z - 121200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR FL PANHANDLE...
   
   ...SYNOPSIS...
   A MID/UPPER-LEVEL LOW INVOF LAKE ERIE WILL EVOLVE INTO A SHORT WAVE
   TROUGH AS IT SWINGS ACROSS THE MID ATLANTIC/SRN NEW ENGLAND...WITH A
   SECONDARY CLOSED LOW DROPPING SWD ACROSS NERN ONTARIO/WRN QUEBEC. A
   COLD FRONT WILL PUSH SLOWLY SEWD THROUGH THE SERN
   STATES...REINFORCING A MILD/DRY AIR MASS ACROSS THE REGION. WIND
   SPEEDS WILL GENERALLY REMAIN MODEST EXCEPT INVOF THE FRONTAL
   BOUNDARY. FARTHER WEST...A SHORT WAVE TROUGH OVER THE NRN ROCKIES
   WILL DEAMPLIFY AS IT IMPINGES ON THE LARGE-SCALE RIDGE AXIS. A
   PROGRESSIVE UPPER-LEVEL TROUGH WILL REACH THE W COAST BY EARLY FRI.
   
   ...CRITICAL FIRE WEATHER AREA - FL PANHANDLE...
   
   PRIMARY CONDITIONS: LOW RH / MODERATE WINDS / LONG-TERM DROUGHT
   
   AS A COLD FRONT PASSES THROUGH THE AREA LATER THIS MORNING AND THIS
   AFTERNOON...N/NWLY WINDS WILL STRENGTHEN DRYING. MODEL GUIDANCE
   SUGGESTS LOW-LEVEL FLOW WILL BE STRONGEST JUST BEHIND THIS BOUNDARY.
   THIS SHOULD BE FAVORABLY JUXTAPOSED WITH PEAK HEATING...RESULTING IN
   SUFFICIENT MIXING FOR SUSTAINED WINDS AROUND 15 MPH. TEMPERATURES
   SHOULD WARM INTO THE LOWER TO MIDDLE 80S LEADING TO CRITICALLY LOW
   RH FROM 25 TO 30 PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0451 AM CDT THU OCT 11 2007
   
   VALID 121200Z - 131200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NWRN/CNTRL AZ...EXTREME SWRN UT...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL TROUGH OFF THE W COAST WILL SLOW ITS PROGRESSION AS
   IT SHIFTS INLAND ACROSS THE SWRN STATES/SRN GREAT BASIN BY EARLY
   SAT. AN ASSOCIATED BELT OF STRONG SWLY MID-LEVEL FLOW WILL BECOME
   CENTERED OVER SRN CA THROUGH THE CO RIVER VALLEY FRI AFTERNOON. IN
   THE EAST...AN UPPER-LEVEL LOW WILL REMAIN QUASI-STATIONARY ACROSS
   SERN CANADA. AT THE SURFACE...AN EXPANSIVE AREA OF HIGH PRESSURE
   WILL SLOWLY SLIDE EWD FROM THE MS RIVER VALLEY TOWARDS THE OH/TN
   RIVER VALLEY.
   
   ...CRITICAL FIRE WEATHER AREA - NWRN/CNTRL AZ...EXTREME SWRN UT...
   
   PRIMARY CONDITIONS: MODERATE WINDS / LOW RH / LONG-TERM DROUGHT
   
   SWLY WINDS WILL INCREASE WITH THE APPROACH OF A POTENT UPPER-LEVEL
   TROUGH FROM THE ERN PACIFIC. ALTHOUGH MID/UPPER-LEVEL FLOW WILL
   BECOME STRONG...RELATIVELY WEAK MID-LEVEL LAPSE RATES SHOULD TEND TO
   DETER DEEP BOUNDARY-LAYER MIXING DURING PEAK HEATING.
   STILL...SUSTAINED WINDS AROUND 20 MPH APPEAR LIKELY CLOSER TO HIGHER
   TERRAIN...MAINLY ALONG S/SWRN FACING SLOPES OF THE MOGOLLON RIM NWWD
   TO THE SWRN UT MTNS. ALTHOUGH INSOLATION MAY BE SOMEWHAT LIMITED BY
   INCREASING CIRRUS...THE ANTECEDENT DRY AIR MASS IN THE LOW-LEVELS
   SHOULD BE SUFFICIENT FOR CRITICALLY LOW RH VALUES BETWEEN 10 AND 15
   PERCENT.
   
   ...SOUTHEAST...
   LOW RH WILL PLAGUE MUCH OF THE REGION /OUTSIDE OF SRN FL/ AS NLY
   WINDS CONTINUE. MIN RH VALUES FROM 25 TO 35 PERCENT WILL BE COMMON
   AS TEMPERATURES WARM INTO THE MIDDLE 70S TO LOWER 80S. SUSTAINED
   WIND SPEEDS WILL BE WEAK AS SURFACE RIDGING EXPANDS ACROSS THE
   AREA...MITIGATING ANY CRITICAL FIRE WEATHER THREAT.
