   VALID 261200Z - 271200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL LOW OVER SRN QUEBEC WILL MOVE EAST...AS A SHORT WAVE
   TROUGH AMPLIFIES S/SEWD FROM THE S-CNTRL CANADIAN PRAIRIES ACROSS
   THE NRN GREAT LAKES/UPPER MIDWEST. THIS AMPLIFICATION WILL AID IN
   THE EWD ACCELERATION OF A CLOSED LOW FROM FAR NRN MEXICO ONTO THE
   SRN PLAINS. AT THE SURFACE...A MASSIVE AREA OF HIGH PRESSURE FROM
   THE SRN PLAINS NEWD THROUGH THE OH VALLEY WILL WEAKEN AS IT BECOMES
   CENTERED OVER THE SERN CONUS BY 12Z SAT.
   
   ...SRN AL/SRN GA/MUCH OF FL...
   A DRY AIR MASS WAS IN PLACE ACROSS THE AREA THIS MORNING WITH DEW
   POINTS IN THE 20S AND 30S UNDER MODEST NLY FLOW. WITH FULL
   INSOLATION...TEMPERATURES WILL WARM FROM THE UPPER 50S N TO AROUND
   70 S. THIS WILL PRODUCE CRITICALLY LOW RH VALUES FROM 20 TO 30
   PERCENT...EXCEPT ALONG THE E COAST OF FL WHERE WINDS WILL BECOME
   NELY AND ONSHORE FLOW DEVELOPS. THE LIMITING FACTOR TO A CRITICAL
   AREA ISSUANCE WILL BE THE STRENGTH OF THE WINDS. WITH A LARGE AREA
   OF HIGH PRESSURE APPROACHING...LOW-LEVEL WINDS WILL SUBSTANTIALLY
   WEAKEN LATER THIS MORNING THROUGH THE AFTERNOON. SURFACE WIND SPEEDS
   WILL BE AROUND 10 MPH OR LESS DURING THE PERIOD OF LOW RH.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0349 AM CST FRI JAN 26 2007
   
   VALID 271200Z - 281200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   HIGHLY AMPLIFIED UPPER-LEVEL PATTERN WILL EXIST ACROSS THE CONUS
   WITH A TROUGH OVER THE CNTRL/ERN CONUS AND A REX BLOCK CENTERED JUST
   OFF THE W COAST. SURFACE LOW PRESSURE OVER THE CNTRL GREAT LAKES
   WILL INITIALLY WEAKEN WHILE CYCLONE DEVELOPMENT OCCURS OFF THE LA
   COAST. THESE LOWS WILL QUICKLY MOVE EWD REACHING THE ERN SEABOARD BY
   12Z SUN.
   
   ...PIEDMONT AND COASTAL PLAINS OF THE CAROLINAS...
   A MODERATE BELT OF 30 TO 40 MPH LOW-LEVEL W/SWLY FLOW SHOULD DEVELOP
   EARLY SAT TO THE S OF THE CNTRL GREAT LAKES CYCLONE. ALTHOUGH THE
   LOW IS EXPECTED TO WEAKEN THROUGH THE DAY WITH A COINCIDENT
   WEAKENING OF THE SURFACE PRESSURE GRADIENT...DAYTIME HEATING WILL
   ALLOW SOME MECHANICAL MIXING OF THE HIGHER MOMENTUM AIR ALOFT.
   SUSTAINED SURFACE WINDS SHOULD REACH 15 TO 20 MPH. ALTHOUGH SOME
   LOW-LEVEL MOISTENING WILL OCCUR WITH UPSTREAM DEW POINTS IN THE
   20S...TEMPERATURES WILL ALSO WARM INTO THE UPPER 50S TO MIDDLE 60S.
   THIS SHOULD LEAD TO MARGINALLY LOW RH VALUES AROUND 25 PERCENT.
