   ...CRITICAL FIRE WEATHER AREA FOR SRN AZ...
   
   ...SYNOPSIS...
   A VIGOROUS TROUGH WILL MOVE FROM OFF THE SRN COAST OF CALIFORNIA
   INTO THE FOUR CORNERS REGION DURING THE FORECAST PERIOD...BRINGING
   RAIN AND THUNDERSTORMS FROM THE CENTRAL ROCKY MOUNTAINS TO THE GREAT
   PLAINS.  AN OCCLUDED FRONT ASSOCIATED WITH THE TROUGH WILL MOVE
   THROUGH ARIZONA DURING SUNDAY AFTERNOON...WITH STRONG WINDS AND DRY
   CONDITIONS BEHIND THE FRONT. ELSEWHERE IN THE COUNTRY...A SURFACE
   HIGH PRESSURE CENTERED OVER THE OHIO RIVER VALLEY WILL AID IN LOW
   HUMIDITY VALUES IN THE SOUTHEAST...WHILE A LOW PRESSURE SYSTEM TO
   THE NORTHEAST OF THE GREAT LAKES REMAINS FAIRLY STATIONARY WITH RAIN
   AND SNOW.
   
   ...CRITICAL FIRE WEATHER AREA - SRN AZ...
   
   PRIMARY CONDITIONS: GUSTY WINDS AND LOW RH
   
   WINDS WILL SHIFT TO A NORTHWESTERLY TO WESTERLY DIRECTION DURING THE
   AFTERNOON HOURS ON SUNDAY AS AN OCCLUDED FRONT PASSES THROUGH THE
   REGION...WITH SPEEDS APPROACHING 20 TO 30 MPH AND HIGHER GUSTS.
   RELATIVE HUMIDITY VALUES WILL DIP TO AROUND 10 TO 15 PERCENT AS THE
   DRY AIR MASS BEHIND THE FRONT MOVES INTO THE REGION...AND AS SURFACE
   TEMPERATURES CLIMB INTO THE 70S F...CRITICAL FIRE WEATHER CONDITIONS
   WILL EXIST. THE HIGHEST DANGER APPEARS TO BE DURING THE AFTERNOON
   HOURS DIRECTLY AFTER PASSAGE OF THE FRONT WHEN THE
   TEMPERATURE...WIND SPEED...AND MOISTURE CRITERIA ARE CRITICAL...BUT
   THE FRONT WILL MOVE THROUGH THE REGION QUICKLY SO WIND SPEEDS WILL
   WEAKEN SIGNIFICANTLY...ESPECIALLY BY 06Z.
   
   ...NRN FL...
   SURFACE HIGH PRESSURE IN THE SOUTHEAST WILL HELP SUSTAIN A DRY AIR
   MASS...WITH RELATIVE HUMIDITY VALUES AROUND 25 TO 30 PERCENT IN
   NORTHERN TO NORTH CENTRAL FLORIDA DURING SUNDAY AFTERNOON...AND
   TEMPERATURES IN THE 70S F. CONDITIONS WILL THEREFORE APPROACH
   CRITICAL VALUES...BUT NWLY WIND SPEEDS WILL BE LIGHT...AROUND 5 TO
   10 MPH.

   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG TROUGH WILL MOVE OUT OF THE FOUR CORNERS REGION AND INTO
   THE SOUTHERN GREAT PLAINS DURING THE DAY ON MONDAY...BRINGING RAIN
   AND THUNDERSTORMS TO THE AREA. A LEE CYCLONE AND TROUGH WILL DEVELOP
   INTO THE TX PANHANDLE WITH THIS STORM SYSTEM...AND CONDITIONS WILL
   APPROACH CRITICAL FIRE WEATHER CRITERIA. IN THE NORTHEAST...A LOW
   PRESSURE SYSTEM...TO THE NORTHEAST OF THE GREAT LAKES...WILL REMAIN
   NEARLY STATIONARY WITH PRECIPITATION OCCURRING IN NEW ENGLAND...AND
   A NEW TROUGH WILL BEGIN TO IMPACT THE PACIFIC NORTHWEST.
   
   ...ERN NM/WRN TX...
   STRONG WLY WINDS ALOFT WILL AID IN CREATING A STRONG AND GUSTY WIND
   ENVIRONMENT BEHIND A SURFACE DRYLINE THAT WILL EXTEND FROM A LEE
   CYCLONE IN THE TX PANHANDLE SOUTHWARD INTO SW TX. BEHIND THE
   DRYLINE...RELATIVE HUMIDITY VALUES WILL BE AROUND 25 TO 30 PERCENT
   AND WLY WIND SPEEDS WILL BE STRONG AND GUSTY WITH SPEEDS AT 20 TO 30
   MPH. WITH SURFACE TEMPERATURES IN THE 60S TO LOW 70S F...FIRE
   WEATHER CONDITIONS WILL BE NEAR CRITICAL AND MAY NEED TO BE UPGRADED
   ON DAY1 IF THE STORM SYSTEM APPEARS TO BE STRONGER THAN CURRENTLY
   FORECAST.
   
   ...NRN FL...
   AS IN PREVIOUS DAYS...A SURFACE HIGH PRESSURE SYSTEM IN THE
   SOUTHEAST U.S. WILL SUSTAIN NLY WINDS AND A DRY AIR MASS IN NRN AND
   NORTH CNTRL FL. RELATIVE HUMIDITY VALUES AROUND 25 TO 30 PERCENT AND
   SURFACE TEMPERATURES IN THE LOW 70S F WILL CREATE NEAR CRITICAL
   CONDITIONS...HOWEVER...WIND SPEEDS AT 5 TO 10 MPH WILL MINIMIZE THE
   RISK.
