   NWS STORM PREDICTION CENTER NORMAN OK
   0234 AM CDT MON APR 20 2009
   
   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   HIGHLY AMPLIFIED UPPER-LEVEL PATTERN WILL PERSIST WITH A LARGE-SCALE
   TROUGH FROM THE GREAT LAKES TO THE DEEP SOUTH AND A RIDGE ACROSS THE
   WEST. EXPANSIVE SURFACE RIDGE WILL REMAIN ANCHORED FROM THE PACIFIC
   NW TO THE SRN PLAINS...WITH A TROUGH DRAPED ACROSS THE GULF OF CA
   INTO THE LOWER CO RIVER VALLEY.
   
   ...SERN AZ...
   A MODEST SURFACE PRESSURE GRADIENT SHOULD RESULT IN A SHORT PERIOD
   OF MODERATE ELY WINDS JUXTAPOSED WITH RH FALLING BELOW 15 PERCENT
   AROUND NOON. LATEST MODEL FORECASTS SUGGEST WINDS WILL BE SOMEWHAT
   LIGHTER THAN IN PREVIOUS RUNS. SUSTAINED SPEEDS MAY BRIEFLY APPROACH
   15 MPH PRIOR TO WEAKENING IN THE AFTERNOON AS THE PRESSURE GRADIENT
   RELAXES.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0407 AM CDT MON APR 20 2009
   
   VALID 211200Z - 221200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   HIGHLY AMPLIFIED LARGE-SCALE UPPER-LEVEL TROUGH WILL SLOWLY SHIFT
   EWD ACROSS THE ERN CONUS. UPPER-LEVEL RIDGE OVER THE WRN CONUS WILL
   SLOWLY DEAMPLIFY AS A WEAK SRN STREAM IMPULSE APPROACHES THE
   CNTRL/SRN CA COAST.
   
   ...NERN CA TO CNTRL ORE...
   LATEST AVAILABLE GACC/FUELS INFORMATION INDICATE THAT FUELS SHOULD
   GENERALLY REMAIN TOO MOIST TO SUPPORT POTENTIAL FOR A CRITICAL FIRE
   AREA. NEVERTHELESS...ISOLATED DRY TSTMS MAY DEVELOP LATE TUE
   AFTERNOON OVER HIGHER TERRAIN ALONG AND E OF THE CASCADES AS THE WRN
   RIDGE BEGINS TO BREAK DOWN. WELL-ABOVE NORMAL TEMPERATURES WILL
   CONTRIBUTE TO INVERTED-V TYPE THERMODYNAMIC PROFILES.
   HOWEVER...MID-LEVEL MOISTENING AND DEGREE OF UPPER-LEVEL FORCING
   APPEARS MODEST...SUGGESTING CONVECTIVE COVERAGE SHOULD BE SPARSE.
