   ...SYNOPSIS...
   AN UPPER RIDGE WILL REMAIN IN PLACE ACROSS THE ERN U.S. WITH SURFACE
   HIGH PRESSURE CENTERED OVER THE MID ATLANTIC AND SE. THIS WILL
   RESULT IN WARM AND DRY CONDITIONS FOR MOST OF THE AREA E OF THE MS
   RIVER. SLY WINDS WILL INCREASE AHEAD OF A SURFACE LOW WHICH WILL BE
   OVER ERN NEB/WRN IA LATE TODAY. THE COMBINATION OF INCREASED WINDS
   AND LOW RH WILL ENHANCE FIRE THREAT FROM THE UPPER MS VALLEY INTO
   THE GREAT LAKES. TO THE SW...ANOTHER STRONG UPPER TROUGH WILL
   DEVELOP SEWD INTO THE DESERT SW PRODUCING GUSTY SWLY WINDS OVER
   AZ/NM.

   SURFACE HIGH. THE STRONGEST WINDS WILL BE OVER IL INTO WI WHERE
   GUSTS OVER 30 MPH ARE LIKELY. THE HIGH WILL MAINTAIN DRY SURFACE
   TRAJECTORIES WITH MIN RH VALUES AVERAGING 25-35 PERCENT. KBDI VALUES
   ARE LOW ACROSS THE REGION THUS OVERALL THREAT EXPECTED TO ONLY BE
   MARGINALLY CRITICAL.
   
   ...SERN STATES...
   PRESENCE OF SURFACE HIGH WILL MAINTAIN VERY DRY AND WARM CONDITIONS
   WITH MAINLY LIGHT WINDS. MIN RH WILL DECREASE TO 20-30 PERCENT OVER
   MUCH OF THE REGION...WHILE WINDS REMAIN RELATIVELY LIGHT AT LESS
   THAN 10 MPH. STRONG ELY FLOW TO 15 MPH WILL OCCUR ALONG THE ATLANTIC
   COAST BUT THIS WILL ALSO INCREASE RH.  GIVEN A VERY WARM AND DRY AIR
   MASS...ANY ONGOING FIRES MAY EXPERIENCE INCREASED GROWTH WITH A MDT
   TO HIGH HAINES INDEX.
   
   ...SWRN STATES...
   A VERY DRY AIR MASS WILL EXTEND FROM W TX ACROSS NM INTO SRN AZ.
   MODERATE SWLY WINDS OF 10-20 MPH WILL BE COMMON DURING THE AFTERNOON

   FROM SRN NV ACROSS NRN AZ WHERE NOSE OF UPPER LEVEL JET WILL BY 00Z.
   RH LEVELS WILL ALSO BE HIGHER IN THESE WINDIER LOCATIONS THUS
   CRITICAL FIRE CONDITIONS NOT ANTICIPATED...ALTHOUGH THREAT WILL

   ATLANTIC STATES. HIGH PRESSURE CENTER WILL BE OVER NRN/CNTRL FL WITH
   WARM AND DRY CONDITIONS CONTINUING.
   
   ...CRITICAL FIRE WEATHER AREA - SERN AZ...SRN NM...FAR W TX...
   
   PRIMARY CONDITIONS: STRONG SWLY WINDS...LOW RH
   
   STRONG UPPER JET WILL BE OVERHEAD MON AFTERNOON. DEEPENING LOW TO
   THE E AND STRONG MIXING WILL ALLOW HIGH WINDS TO REACH THE SURFACE
   WITH SUSTAINED SPEEDS OF 20-30 MPH LIKELY WITH GUSTS OF 30-40 MPH
   EASILY ATTAINED. MIN RH OF 10-15 PERCENT IS EXPECTED RESULTING IN
   CRITICAL FIRE CONDITIONS.
   
   ...GA NEWD INTO VA...
   SWLY WINDS WILL INCREASE AS LOW PRESSURE TROUGH PASSES TO THE NW.
