   NWS STORM PREDICTION CENTER NORMAN OK
   0320 AM CDT WED MAY 28 2008
   
   VALID 281200Z - 291200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NRN AZ...WRN N M...SRN AND
   ERN UT...WRN CO...
   
   ...SYNOPSIS...
   AN UPPER RIDGE WILL CONTINUE TO BUILD OVER THE MIDDLE OF THE CONUS
   WHILE A LARGE UPPER TROUGH AND LOW REMAINS NEARLY STATIONARY OVER
   THE W COAST/ERN PACIFIC. A VERY WARM AIR MASS WILL SPREAD NWD ACROSS
   THE FOUR CORNERS STATES WHILE WINDS INCREASE AHEAD OF THE TROUGH. TO
   THE E...AN EXPANSIVE AREA OF HIGH PRESSURE WILL STRETCH FROM THE
   UPPER MS VALLEY EWD INTO NEW ENGLAND...PROVIDING VERY DRY BUT COOL
   CONDITIONS.  HIGH PRESSURE JUST OFF THE SE U.S. COAST WILL KEEP
   CONDITIONS WARM AND RELATIVELY DRY FOR FL.
   
   ...CRITICAL FIRE WEATHER AREA - MUCH OF NRN AZ...WRN N M...SRN AND
   ERN UT...WRN CO...
   
   PRIMARY CONDITIONS: STRONG WINDS AND LOW RH
   
   WINDS WILL INCREASE AHEAD OF AN UPPER TROUGH WITH A WARM AND DRY AIR
   MASS IN PLACE. SWLY WINDS OF 20-25 MPH ARE EXPECTED FROM NRN AZ INTO
   WRN CO...AS WELL AS WRN NM WITH HIGHER GUSTS DURING THE AFTERNOON
   ESPECIALLY NEAR RIDGE TOPS. BY PEAK HEATING MIN RH OF 10-15 PERCENT
   WILL BE WIDESPREAD...WITH LOCALIZED UPPER SINGLE DIGITS WRN NM AND
   ERN AZ.
   
   ...FL...
   WARM AND DRY WEATHER WILL CONTINUE OVER THE SERN STATES WITH HIGH
   PRESSURE IN PLACE. DURING THE AFTERNOON...RH WILL DROP LOCALLY INTO
   THE 35-40 PERCENT RANGE FOR A FEW HOURS...WHILE TEMPERATURES RISE TO
   85-90. ELY WINDS NEAR 15 MPH WILL OCCUR ALONG THE E COAST...BUT RH
   WILL ALSO BE HIGHER IN THOSE AREAS. OVERALL...THERE WILL BE AN
   INCREASED THREAT OF FIRES FOR A PERIOD DURING THE AFTERNOON BUT
   MARGINAL RH WILL HELP MITIGATE THE THREAT.
   
   ...NEW ENGLAND...
   HIGH PRESSURE WILL BUILD IN FROM THE W...RESULTING IN MILD AND DRY
   WEATHER. LOW PRESSURE OVER CANADA WILL MAINTAIN A MODERATE PRESSURE
   GRADIENT...RESULTING IN SLY WINDS OF 15-20 MPH. MIN RH WILL
   GENERALLY FALL INTO THE 20 PERCENT RANGE AS WELL...RESULTING IN A
   MARGINAL FIRE THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0411 AM CDT WED MAY 28 2008
   
   VALID 291200Z - 301200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SRN UT...NRN AZ...MUCH OF NM AND
   CO...FAR WRN KS AND THE WRN OK/TX PANHANDLES...
   
   ...SYNOPSIS...
   A LARGE AREA OF WARM AND WINDY WEATHER WILL STRETCH FROM THE SRN
   PLAINS ACROSS THE FOUR CORNERS STATES WITH AN UPPER RIDGE IN PLACE
   OVER THE CNTRL U.S. CRITICAL FIRE CONDITIONS WILL OCCUR AS AN UPPER
   TROUGH INTERFACES WITH THE WRN SIDE OF THE RIDGE...FROM AZ INTO CO.
   DRY AND WINDY WEATHER WILL ALSO OCCUR OVER THE NERN U.S. AHEAD OF A
   COLD FRONT...WHILE WARM AND MODERATELY DRY WEATHER CONTINUES FOR FL.
   
   ...CRITICAL FIRE WEATHER AREA - SRN UT...NRN AZ...MUCH OF NM AND
   CO...FAR WRN KS AND THE WRN OK/TX PANHANDLES...
   
   PRIMARY CONDITIONS: STRONG WINDS AND LOW HUMIDITY
   
   A LOW AMPLITUDE UPPER TROUGH WILL BREAK DOWN THE WRN SIDE OF THE SRN
   PLAINS RIDGE...CREATING STRONG WINDS IN THESE AREAS ACROSS THE FOUR
   CORNERS STATES. SUSTAINED SWLY WINDS OF 20-30 MPH ARE LIKELY WITH
   HIGHER GUSTS. MIN RH WILL DIP INTO THE TEENS.
   
   FARTHER E INTO THE HIGH PLAINS...LOW PRESSURE WILL DEEPEN OVER ERN
   CO AND WRN NE/KS. A VERY STRONG PRESSURE GRADIENT WILL
   RESULT...CREATING EXCESSIVE WINDS...SUSTAINED 30-40 MPH WITH GUSTS
   OVER 40 MPH. HIGH TEMPERATURES FROM ERN CO INTO WRN KS AND THE OK/TX
   PANHANDLES WILL REACH THE 90S...WITH MIN RH GENERALLY FROM 15-25
   PERCENT. ONE COMPLICATING FACTOR WILL BE THE LIKELIHOOD OF
   THUNDERSTORMS WITH HAIL AND VERY STRONG WIND GUSTS LATER IN THE DAY.
   OF COURSE ANY RAINFALL WILL END THE CRITICAL THREAT LOCALLY.
   HOWEVER...PRIOR TO ANY RAIN...DANGEROUS FIRE CONDITIONS ARE LIKELY
   WITH RAPIDLY MOVING FIRES POSSIBLE.
   
   ...NEW ENGLAND...
   WLY WINDS WILL INCREASE AHEAD OF A LOW PRESSURE TROUGH/COLD FRONT
   THAT WILL SWEEP SEWD OUT OF CANADA LATE THU. SUSTAINED WLY WINDS
   NEAR 20 MPH ARE LIKELY WITH HIGHER GUSTS. CURRENT RH FORECASTS RANGE
   FROM 20 TO 40 PERCENT. THE MAIN UNCERTAINTY WITH THIS FORECAST IS
   THE RH LEVELS. PORTIONS OF NY AND NEW ENGLAND COULD SEE CRITICAL
   FIRE CONDITIONS IF RH VERIFIES ON THE LOW END. GIVEN ANTECEDENT HIGH
   PRESSURE IN PLACE...THE MOST LIKELY SCENARIO WOULD BE FOR THE LOWER
   RH VALUES TO VERIFY. HOWEVER...WILL DEFER TO NEXT DAY 1 OUTLOOK
   BEFORE ANY CRITICAL FIRE UPGRADE.
   
   ...SRN PLAINS...
   IT WILL BE QUITE WARM UNDER THE UPPER RIDGE WITH HIGH TEMPERATURES
   LARGELY IN THE 90S. SELY WINDS WILL INCREASE TO 10-20 MPH OVER MUCH
   OF OK INTO CNTRL TX...WITH HIGHER GUSTS ESPECIALLY LATE OVER WRN TX.
   RH LEVELS OVERALL WILL BE BELOW CRITICAL LEVELS AS LOW LEVEL
   MOISTURE RETURNS NWWD. HOWEVER...A FEW AREAS MAY SEE 20-25 PERCENT
   AT PEAK HEATING.
   
   ...FL...
   WARM AND DRY CONDITIONS WILL PERSIST FOR FL WITH HIGH PRESSURE TO
   THE E. INTERIOR LOCATIONS MAY SEE RH DIPPING INTO THE 35-40 PERCENT
   RANGE AT PEAK HEATING. MODERATELY HIGH KBDI VALUES...AS WELL AS
   MULTIPLE DAYS OF WARM AND DRY WEATHER...MAY RESULT IN AN INCREASED
   FIRE THREAT DURING THE AFTERNOON. ELY WINDS OF 10-15 MPH WILL ALSO
   ADD TO THE FIRE DANGER. HOWEVER...LARGE SCALE CRITICAL CONDITIONS
   ARE NOT ANTICIPATED BASED ON FORECAST RH LEVELS.
