   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0334 AM CST WED FEB 07 2007
   
   VALID 071200Z - 081200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   POLAR VORTEX WILL LINGER ACROSS THE EASTERN CANADIAN PROVINCES
   TODAY...WITH A BROAD CYCLONIC UPPER FLOW CONTINUING FROM THE NORTH
   CENTRAL STATES THROUGH THE ATLANTIC SEABOARD.  THIS WILL HELP
   MAINTAIN AN ARCTIC AIR MASS OVER A LARGE AREA EAST OF THE ROCKIES. 
   SHALLOW LEADING EDGE OF THIS AIR MASS MAY BEGIN TO ADVANCE TO THE
   LEE OF THE SOUTHERN APPALACHIANS...AND DEEPER INTO THE SOUTHERN TIER
   STATES...IN THE WAKE OF A SHORT WAVE TROUGH PROGRESSING OFF THE
   ATLANTIC SEABOARD EARLY IN THE DAY.  MEANWHILE...TO WEST OF THE
   CONTINENTAL DIVIDE...WARM/DRY CONDITIONS WILL PERSIST BENEATH
   WEAKENING UPPER RIDGE ACROSS PARTS OF THE SOUTHERN GREAT BASIN AND
   THE SOUTHERN PLATEAU.  THE FIRST IN A SERIES OF SHORT WAVE TROUGHS
   EMANATING FROM A BROADER SCALE TROUGH OVER THE EASTERN PACIFIC IS
   FORECAST TO LIFT THROUGH CENTRAL AND NORTHERN PACIFIC COASTAL AREAS.
    DESPITE LIKELY WEAKENING AS IT PROGRESSES INLAND...SYSTEM IS
   EXPECTED TO BE ACCOMPANIED BY THICKENING CLOUD COVER NORTH/WEST OF
   THE FOUR CORNERS STATES...AND COOLER/WET CONDITIONS WEST OF THE
   CASCADES...AND PARTS OF NORTHERN/CENTRAL CALIFORNIA.
   
   ...SOUTHEAST GEORGIA/NORTHEAST FLORIDA...
   BREEZY CONDITIONS APPEAR POSSIBLE EARLY IN THE DAY.  BUT...BY PEAK
   AFTERNOON HEATING...WESTERLY WINDS ARE EXPECTED TO RELAX AS A
   VIGOROUS SHORT WAVE TROUGH PROGRESSES OFF TO THE EAST OF NORTHERN/
   MID ATLANTIC COASTAL AREAS.  AFTERNOON TEMPERATURES MAY TOP OUT IN
   THE 60S AND 70S...BUT SUFFICIENT MOISTENING OF REMNANT CONTINENTAL
   AIR MASS IS EXPECTED FOR LOWEST SURFACE RELATIVE HUMIDITIES ONLY
   BRIEFLY DIPPING INTO THE 30-40 PERCENT RANGE.  THIS IS EXPECTED TO
   MINIMIZE FIRE POTENTIAL...DESPITE HIGHER FIRE DANGER CLASSES/ LONGER
   TERM DRYNESS.
   
   ...SOUTHERN ARIZONA INTO SOUTHERN NEVADA...
   DAYTIME HEATING/MIXING MAY CONTRIBUTE TO LOCALIZED GUSTS APPROACHING
   20 MPH LATE THIS AFTERNOON...BUT THIS SHOULD BE ISOLATED/BRIEF
   ENOUGH TO MINIMIZE FIRE POTENTIAL...DESPITE WARM/DRY CONDITIONS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0334 AM CST WED FEB 07 2007
   
   VALID 081200Z - 091200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   MODELS INDICATE THAT UPPER RIDGING OVER THE INTERMOUNTAIN WEST WILL
   BECOME SUPPRESSED THURSDAY...AS A SHORT WAVE TROUGH CONTINUES
   EASTWARD ACROSS THE GREAT BASIN.  THIS WILL PROBABLY CONTRIBUTE TO A
   MORE ZONAL FLOW ACROSS THE CENTRAL/SOUTHERN ROCKIES...AND WEAK
   SURFACE TROUGHING TO THE LEE OF THE SOUTHERN ROCKIES.  DOWNSLOPE
   WARMING/DRYING ACROSS PARTS OF SOUTHWEST TEXAS INTO SOUTHERN NEW
   MEXICO MAY APPROACH CRITICAL LEVELS DURING THE LATE AFTERNOON HOURS.
    BUT...PEAK WINDS ARE EXPECTED TO GENERALLY REMAIN BELOW 20
   MPH...LIMITING OVERALL FIRE POTENTIAL.
   
   OTHERWISE...LITTLE CHANGE TO THE LARGE-SCALE PATTERN IS EXPECTED
   THROUGH THIS PERIOD.  THE COLD AIR MASS SEEMS LIKELY TO PENETRATE
   MUCH OF THE REMAINDER OF THE U.S. TO THE LEE OF THE ROCKIES...WITH
   THE EXCEPTION OF PARTS OF DEEP SOUTH TEXAS AND THE FLORIDA
   PENINSULA.
