   VALID 211200-221200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   LARGE-SCALE SPLIT FLOW PATTERN PROGGED TO EVOLVE THRU FCST PERIOD
   AS WNWLY POLAR BRANCH CONTINUES TO YIELD COLD CONDITIONS ACROSS THE
   NRN TIER INTO MUCH OF THE ERN U.S. WHILE MUCH WEAKER SUBTROPICAL
   BRANCH STAYS ACROSS THE SRN TIER INTO THE SERN STATES. SUBTROPICAL
   SHORTWAVE IMPULSE PROGGED TO ADVANCE EWD FROM NM/AZ TO AL/MS BY
   22/12Z WHILE NEXT SHORTWAVE TROUGH HEADS QUICKLY FROM CA/ORE SEWD
   INTO FOUR CORNERS REGION AHEAD OF BUILDING WEST COAST RIDGE. STRONG
   CANADIAN COLD FRONTAL BOUNDARY IS EXPECTED TO STRETCH FROM THE NRN
   ROCKIES...SSEWD THRU THE LEE REGION...EWD THRU SCNTRL TX...EWD THRU
   THE SERN STATES BY 22/00Z SEPARATING MILDER PACIFIC AIR AND MUCH
   COLDER CANADIAN AIRMASS.
   
   ...SERN NM/WRN TX...
   JUST AHEAD OF A SLOW MOVING/STATIONARY COLD FRONTAL BOUNDARY...
   ANOTHER DAY OF ABOVE AVERAGE TEMPERATURES...BRISK WLY COMPONENT
   WINDS...AND MARGINALLY LOW RH VALUES IS EXPECTED TO AFFECT SERN NM
   AND WRN TX. DESPITE THE EWD TRANSLATION OF A SHORTWAVE IMPULSE INTO
   THE LOWER MS VALLEY...MODERATELY STRONG MID-LVL DOWNSLOPE FLOW WILL
   CONTINUE TO YIELD A WINDY /WNWLY 15-25 MPH/ WARM...AND DRY BOUNDARY
   LAYER TODAY. HIGH TEMPERATURES WILL RANGE FROM NEAR 60 IN ELEVATED
   AREAS TO THE LOW-MID 70S IN THE ADJACENT PLAINS WITH MINIMUM RH
   VALUES FROM AROUND 20-30 PERCENT. HOWEVER...WITH THE STRONGER WIND
   REGIME TO BE MAINLY LIMITED TO THE MRNG/EARLY AFTERNOON HOURS AND
   THE MARGINALITY OF THE EXPECTED LOW-LVL RH VALUES...A CRITICAL AREA
   WILL NOT BE ISSUED. DESPITE NON-ISSUANCE...SOME LOCALIZED CRITICAL
   LEVEL FIRE WX CONDITIONS ARE LIKELY.
   
   ...SRN/SCNTRL FL...
   ON THE BACKSIDE OF A SFC ANTICYCLONE SOME DRIER AIR IS EXPECTED TO
   LINGER IN PARTS OF SRN AND SCNTRL FL DURING THE PERIOD /MINIMUM RH
   30-35 PERCENT/...HOWEVER RATHER WEAK WINDS WILL PRECLUDE ANY
   SERIOUS FIRE WX CONCERNS.

   400 AM CST TUE JAN 21 2003
     
   DAY 2 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWI98 KWNS
   VALID 221200-231200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   PACIFIC COAST MID-UPPER LVL RIDGE PROGGED TO WEAKEN AND MOVE INTO
   THE INTERIOR WEST AS SEVERAL SHORTWAVE IMPULSES SURGE INLAND FROM
   THE ERN PACIFIC DURING THE PERIOD. FURTHER EAST...ANOTHER SHORTWAVE
   TROUGH TO TRANSLATE FROM THE AZ/NM REGION...ESEWD THRU TX...INTO
   THE GULF OF MEXICO BY 23/12Z AS MUCH COLDER AIR ASSOCIATED WITH A
   1045 SFC HIGH PRESSURE AREA MOVES INTO THE NRN PLAINS. A REGION OF
   BRISK WNWLY WINDS IS EXPECTED TO AFFECT THE SERN NM/WRN TX AREA
   DURING THE EARLY PORTION OF THE FCST PERIOD...BUT WINDS WILL WEAKEN
   AS THE AFOREMENTIONED SHORTWAVE TROUGH MOVES SEWD INTO SRN TX.
   SOUTH OF THE PRIMARY COLD FRONTAL BOUNDARY...PARTS OF SRN/SCNTRL FL
   WILL AGAIN EXPERIENCE DRY BOUNDARY LAYER CONDITIONS...BUT THE LACK
   OF A SIGNIFICANT WIND REGIME WILL AGAIN PRECLUDE THESE AREAS FROM
   ANY CRITICAL CONSIDERATION.
