   OK...ERN NM...
   
   ...SYNOPSIS...
   A DEAMPLIFYING UPPER TROUGH OVER THE E COAST WILL MOVE EWD OVER THE
   WRN ATLANTIC.  EARLY MORNING SATELLITE IMAGERY DEPICTS A POTENT
   UPPER DISTURBANCE MOVING INTO THE PACIFIC NW REGION.  THIS FEATURE
   WILL QUICKLY MOVE SEWD OVER THE INTERMOUNTAIN WEST AND BE LOCATED
   OVER THE SRN HIGH PLAINS BY THE END OF THE PERIOD.  AT THE
   SURFACE...A LOW WILL DEVELOP IN THE VICINITY OF THE CENTRAL HIGH
   PLAINS WITH A TROUGH EXTENDING SWD INTO THE SRN HIGH PLAINS.  A DRY

   ...CRITICAL FIRE WEATHER AREA - LARGE PART OF CENTRAL AND W TX...SW
   OK...ERN NM...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH
   
   STRONG SLY TO WSWLY WINDS WILL LIKELY DEVELOP IN RESPONSE TO A
   STRENGTHENING SURFACE PRESSURE GRADIENT.  UNSEASONABLY WARM
   AFTERNOON TEMPS IN THE UPPER 60S/70S F DEG OVER A LARGE PART OF THE
   REGION WILL LEAD TO CRITICALLY LOW RH.  TWO SCENARIOS APPEAR
   PROBABLE DURING THE FORECAST PERIOD.  1---A LARGE PART OF CENTRAL
   AND N-CENTRAL TX AND SWRN OK WILL LIKELY EXPERIENCE STRONG SLYS
   /20-30 MPH/ DURING THE AFTERNOON HOURS OWING TO AN INCREASING
   PRESSURE GRADIENT.  MODEL GUIDANCE SUGGESTS MIN RH WILL FALL INTO
   THE 20S WITH MIN RH AS LOW AS THE UPPER TEENS IN LOCALIZED AREAS. 
   2---THE WRN PORTION OF THE CRITICAL AREA OVER PARTS OF THE
   TRANSPECOS/CAPROCK AND ERN PLAINS OF NM WILL LIKELY BE SOMEWHAT
   DEPENDENT ON THE MAGNITUDE OF OBSERVED SUSTAINED WINDS.  FORECAST
   SOUNDINGS SUGGEST THE PROBABILITY OF MORE VOLATILE CONDITIONS
   /HIGHER WINDS AND MIN RH/ WILL BE SOMEWHAT TEMPERED DUE TO A STRONG
   CAP PREVENTING DEEP MIXING--WHICH IS IN AGREEMENT ENSEMBLE GUIDANCE.
    NONETHELESS...ENSEMBLE OUTPUT HAS BEEN RELATIVELY CONSISTENT IN
   DEPICTING THE ANTECEDENTLY DRY AIRMASS WITH MIN RH IN THE TEENS.
   
   ...NRN FL PENINSULA...
   WITH DRY CONTINENTAL NWLY LOW LEVEL TRAJECTORIES PREVAILING DURING
   THE PERIOD...RH WILL LIKELY DROP INTO THE 30S AND POSSIBLY THE 20S
   OVER PARTS OF NRN FL.  LATEST ENSEMBLE GUIDANCE SUGGESTS WINDS WILL
   GENERALLY REMAIN BELOW 15 MPH...PRECLUDING A CRITICAL DESIGNATION.
