   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0133 AM CDT FRI MAY 16 2008
   
   VALID 161200Z - 171200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR ERN MT...ND...NERN WY...PORTIONS
   OF SD...
   
   ...SYNOPSIS...
   ALONG THE EAST COAST...LONG WAVE LOW PRESSURE WILL DOMINATE...WITH
   COOLER TEMPERATURES BEHIND THE COLD FRONT AND WIDESPREAD
   PRECIPITATION ALONG AND AHEAD OF THE FRONT...KEEPING HIGHER RELATIVE
   HUMIDITIES ACROSS THESE AREAS. 
     
   IN THE WEST...AN UPPER LOW WILL REMAIN NEARLY STATIONARY OVER NRN
   MEXICO...JUST SOUTH OF THE AZ/NM BORDERS. STRONG HIGH PRESSURE WILL
   BUILD ALONG THE WEST COAST...WITH ABOVE NORMAL TEMPERATURES MAINLY
   NEAR THE COASTAL STATES. 
   
   BETWEEN THE TWO SYSTEMS ACROSS THE NRN PLAINS...AN INCREASE IN THE
   PRESSURE GRADIENT WILL CREATE VERY WINDY CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA - ERN MT...ND...NERN WY...PORTIONS OF
   SD...
   
   PRIMARY CONDITIONS: VERY STRONG WINDS...DROUGHT...LOW RH
   
   VERY WINDY CONDITIONS WILL BE LIKELY IN THE AFTERNOON AS THE
   PRESSURE GRADIENT INCREASES BETWEEN DOMINANT LOW PRESSURE IN THE
   EAST...AND STRENGTHENING HIGH PRESSURE IN THE WEST. WINDS NEAR 20 TO
   30 MPH WITH GUSTS UP TO 40 TO 50 MPH IN THE AFTERNOON CAN BE
   EXPECTED. ATTM INDICATIONS ARE THAT DESPITE TEMPERATURES WARMING
   INTO THE 70S AND 80S...RELATIVE HUMIDITIES WILL BE MARGINAL. GIVEN
   VERY DRY AIRMASS SHOWN ON SATELLITE IMAGERY IN WATER VAPOR AND GOES
   PRECIPITABLE WATER...IT IS ENTIRELY POSSIBLE THAT RELATIVE
   HUMIDITIES WILL BE LOWER THAN MODEL PROGS. GIVEN ANTECEDENT DRY
   CONDITIONS AND STRONG WINDS...AN ENHANCED FIRE DANGER WILL EXIST.
   
   ...PORTIONS OF THE SWRN STATES...
   HOT TEMPERATURES AND RELATIVE HUMIDITIES IN THE TEENS AND SINGLE
   DIGITS WILL PERSIST OVER MUCH OF SRN NV/CA AND SWRN AZ. GUSTY WINDS
   MAY BE POSSIBLE ONCE AGAIN...MAINLY THROUGH THE LOWER CO RIVER
   VALLEY.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0205 AM CDT FRI MAY 16 2008
   
   VALID 171200Z - 181200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE NRN PLAINS...
   
   ...SYNOPSIS...
   AN UPPER LONG WAVE TROUGH WILL DOMINATE IN THE EAST...WHILE A COLD
   FRONT WILL SLOWLY EXIT THE SRN FL PENINSULA. DRIER CONDITIONS WILL
   FOLLOW THIS ACROSS MUCH OF THE SERN STATES...WITH RELATIVE
   HUMIDITIES NEARING CRITICAL THRESHOLDS...ALTHOUGH WINDS WILL
   GENERALLY BE MARGINAL.
   
   IN THE WEST...HIGH PRESSURE AND ABOVE NORMAL TEMPERATURES WILL BE
   DOMINANT WITH THE UPPER RIDGE HOLDING STRONG.
   
   BETWEEN THE TWO SYSTEMS IN THE NRN PLAINS...VERY WINDY CONDITIONS
   WILL BE LIKELY AS THE PRESSURE GRADIENT INCREASES...WHILE WARMING
   TEMPERATURES WILL ALLOW RELATIVE HUMIDITIES TO REACH NEAR CRITICAL
   VALUES IN THE AFTERNOON.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF THE NRN PLAINS...
   
   PRIMARY CONDITIONS: VERY STRONG WINDS...LOW RH
   
   SURFACE LOW PRESSURE ACROSS THE WRN GREAT LAKES ON FRIDAY WILL SHIFT
   EWD THROUGH SUNDAY MORNING...WITH AN INCREASING PRESSURE GRADIENT
   BETWEEN THE EXITING LOW AND APPROACHING HIGH PRESSURE FROM THE WEST.
   ADDITIONALLY...IN UPPER LEVELS THE JET AXIS BETWEEN THE TWO SYSTEMS
   WILL REMAIN STRONG...WHICH WILL ALLOW FOR STRONGER WINDS TO MIX TO
   THE SURFACE IN AFTERNOON HEATING. CURRENT INDICATIONS ARE THAT
   SUSTAINED WIND SPEEDS OF 20 TO 30 MPH WITH GUSTS ONCE AGAIN UP TO 40
   MPH WILL BE POSSIBLE ACROSS MUCH OF THE NRN PLAINS. TEMPERATURES IN
   THE UPPER 60S TO UPPER 70S WILL ALLOW RELATIVE HUMIDITIES TO DROP
   INTO THE MID 20S TO LOWER 30S. ALTHOUGH RELATIVE HUMIDITIES WILL BE
   MARGINAL...STRONG WINDS AND ANTECEDENT DRY CONDITIONS WILL ONCE
   AGAIN LEAD TO CRITICAL FIRE WEATHER CONDITIONS.
   
   ...MUCH OF THE COASTAL PLAINS AND THE NRN FL PENINSULA...
   FOLLOWING A COLD FRONTAL PASSAGE...DRY CONDITIONS WILL BUILD IN
   BEHIND. RELATIVE HUMIDITIES ARE FORECAST TO DROP INTO CRITICAL
   THRESHOLDS ACROSS A WIDESPREAD AREA IN THE SOUTHEAST...ALTHOUGH IN
   GENERAL WINDS WILL REMAIN LIGHTER. THE BEST JUXTAPOSITION OF
   STRONGER WINDS WITH LOW RH APPEARS TO BE MORE LIKELY ACROSS INLAND
   AREAS OF THE CAROLINAS AND VIRGINIA ON THE LEE OF THE APPALACHIANS.
