   ...CRITICAL FIRE WEATHER AREA FOR SRN UT/NW AZ...
   
   ...SYNOPSIS...
   UPPER LOW/TROUGH...NOW LOCATED IN WRN WA...WILL CONTINUE MOVING EAST
   TODAY INTO SRN ALBERTA BY THE END OF THE PERIOD. UPPER TROUGH AXIS
   WILL EXTEND FROM NRN ID INTO NWRN NV BY LATE AFTN...WITH A SFC COLD
   FRONT FROM WY THROUGH CNTRL NV. A BAND OF MODERATELY STRONG
   MID-LEVEL FLOW WILL BE ASSOCIATED WITH THE UPPER TROUGH WITH WIND
   SPEEDS FROM 40-50 KT AT 500MB. CRITICAL FIRE CONDITIONS ARE POSSIBLE
   ACROSS SRN UT/NRN AZ DUE TO DRY FUELS AT LOWER ELEVATIONS AND
   WINDY/DRY WEATHER. A MID LEVEL RIDGE WILL BE THE DOMINANT FEATURE
   ACROSS MUCH OF THE REST OF THE COUNTRY. VERY STRONG SFC WINDS
   ASSOCIATED WITH A DEEPENING SFC LOW PRESSURE SYSTEM ARE EXPECTED
   ACROSS THE NRN/CNTRL PLAINS...BUT HUMIDITY VALUES WILL REMAIN ABOVE
   CRITICAL LEVELS.
   
   ...CRITICAL FIRE WEATHER AREA - SRN UT/NW AZ...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS 15-25 MPH WITH HIGHER GUSTS/MIN
   RH VALUES BELOW 10 PERCENT/CRITICALLY DRY FUELS
   
   OVERALL CONDITIONS MAY NOT BE AS SEVERE AS YESTERDAY...BUT DUE TO
   CRITICALLY DRY FUELS...AN OUTLOOK AREA IS WARRANTED. MINIMUM RH
   VALUES WILL FALL BELOW 10 PERCENT AS YESTERDAY...WITH TEMPS AGAIN
   CLIMBING INTO THE 80S/90S. FORECAST SOUNDINGS INDICATE A MAINLY
   UNIDIRECTIONAL PROFILE...WITH THE POTENTIAL TO MIX DOWN HIGHER
   MOMENTUM AIR TO THE SFC. IT DOES APPEAR THE WINDIER CONDITIONS WILL
   BE ACROSS THE UT PORTION OF THE OUTLOOK AREA.
   
   ...SRN ME...
   LOCAL OBSERVATIONS SUGGEST THAT FIRE DANGER CLASS VALUES ARE HIGH OR
   VERY HIGH ACROSS A GOOD PORTION OF THE STATE...ESPECIALLY IN THE NRN
   AND WRN SECTIONS. MINIMUM RH VALUES TODAY WILL LIKELY BOTTOM OUT IN
   THE 25-30 PERCENT RANGE WITH HIGH TEMPS IN THE 50S/60S. SUSTAINED NW
   WINDS WILL INCREASE TO 10-15 MPH WITH HIGHER GUSTS IN THE AFTN ABOVE
   20-25 MPH. WIDESPREAD CRITICAL FIRE CONDITIONS ARE NOT
   EXPECTED...THOUGH THE COMBINATION OF DRY FUELS AND WINDY/DRY WEATHER
   WILL INCREASE FIRE RISK LOCALLY. DRY AND RELATIVELY WINDY CONDITIONS
   ARE ALSO EXPECTED ACROSS SRN NEW ENGLAND.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0459 AM CDT SUN MAY 13 2007
   
   VALID 141200Z - 151200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER TROUGH BEGINS TO OPEN UP AS IT ADVANCES EAST ACROSS MT AND WRN
   ND ON MONDAY INTO THE NRN PLAINS. UPPER RIDGE BEGINS TO REDEVELOP IN
   THE WEST...WITH MID LEVEL RIDGE AFFECTING THE NORTHEAST STATES EARLY
   IN THE PERIOD. SFC FEATURES OF INTEREST INCLUDE A DEVELOPING LOW
   PRESSURE SYSTEM WITH A COLD FRONT EXTENDING FROM THE UPPER MIDWEST
   THROUGH THE CNTRL/HIGH PLAINS. VERY STRONG WINDS WILL DEVELOP IN THE
   WARM SECTOR OF THIS SYSTEM ON MONDAY...BUT PRECIPITATION WITH THE
   FRONT AND HIGH RELATIVE HUMIDITY VALUES WILL LESSEN THE FIRE WEATHER
   THREAT. STRONG SWLY WINDS WILL DEVELOP AHEAD OF ANOTHER APPROACHING
   FRONT IN THE NORTHEAST...AND NEAR CRITICAL FIRE CONDITIONS MAY BE
   POSSIBLE ACROSS PORTIONS OF ME/NH/VT/MA/CT.
   
   ...NEW ENGLAND STATES...
   DRY AND BREEZY CONDITIONS ARE EXPECTED ON MONDAY ACROSS THE REGION
   AS A WARM FRONT SLOWLY MOVES NORTH. MAX TEMPS WILL CLIMB INTO THE
   50S IN NRN ME AND 60S/70S ELSEWHERE...WITH MIN RH VALUES FALLING
   BELOW 25-30 PERCENT. PORTIONS OF THE AREA /SRN VT AND SRN NH AND ERN
   NY/ HAVE HAD SOME WETTING RAINS OVER THE PAST WEEK...BUT OTHER
   LOCATIONS IN ME AND ERN MA HAVE NOT. THIS AREA WILL BE MONITORED FOR
   A POTENTIAL CRITICAL AREA IN THE NEXT OUTLOOK.
