   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0425 AM CDT WED MAY 16 2007
   
   VALID 161200Z - 171200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A BROAD UPPER RIDGE WILL REMAIN OVER THE WEST THROUGH THE PERIOD.
   MID LEVEL MOISTURE WILL DEVELOP NWWD UNDER THE UPPER RIDGE AND
   SUPPORT SCT TSTMS OVER PORTIONS OF THE CENTRAL ROCKIES. A FEW DRY
   TSTMS WILL BE POSSIBLE ALONG THE NWRN EDGE OF THIS MOISTURE /OVER
   THE ERN GREAT BASIN/. ELSEWHERE ACROSS THE NATION...SEVERAL
   SHORTWAVE TROUGHS WILL DIG SEWD THROUGH THE GREAT LAKES AND HELP TO
   DEVELOP A BROAD UPPER TROUGH OVER THE ERN CONUS. AN ASSOCIATED COLD
   FRONT WILL MOVE SEWD THROUGH THE SERN STATES DURING THE DAY. AHEAD
   OF THIS FRONT SCT PRECIPITATION WILL DEVELOP OVER MUCH OF AL/GA AND
   THE CAROLINAS.
   
   ...ERN GREAT BASIN...
   SATELLITE IMAGERY SHOWS MID LEVEL MOISTURE MOVING NWWD ACROSS THE
   CENTRAL ROCKIES EARLY THIS MORNING. THIS MOISTURE WILL MOVE INTO THE
   ERN GREAT BASIN BY LATER THIS MORNING. TSTMS ARE EXPECTED TO DEVELOP
   BY THIS AFTERNOON OVER THE AREA AS INSTABILITY INCREASES DUE TO THE
   PRESENCE OF THIS MID LEVEL MOIST LAYER AND STEEP MID LEVEL LAPSE
   RATES. GIVEN THE PRESENCE OF A DRY/DEEPLY MIXED BOUNDARY
   LAYER...MAINLY DRY TSTMS ARE EXPECTED. LACK OF GREATER COVERAGE OF
   TSTMS WILL PRECLUDE ANY CRITICAL FIRE WEATHER POTENTIAL.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0428 AM CDT WED MAY 16 2007
   
   VALID 171200Z - 181200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHEAST...
   
   ...SYNOPSIS...
   AS A STRONG SHORTWAVE TROUGH DIGS SEWD THROUGH THE ERN STATES DURING
   THE PERIOD...GUSTY NWLY WINDS WILL DEVELOP IN THE WAKE OF A COLD
   FRONT OVER THE SERN STATES. ALONG WITH LOW RH READINGS...A CRITICAL
   FIRE WEATHER THREAT WILL DEVELOP ACROSS THE AREA DURING THE PERIOD.
   FURTHER WEST...A BROAD UPPER RIDGE WILL REMAIN IN CONTROL OVER MOST
   OF THE WEST WHILE FLATTENING SOMEWHAT OVER THE NRN ROCKIES AS
   SHORTWAVE ENERGY RIDES OVER THE TOP OF THE RIDGE. SCT PRECIPITATION
   WILL AGAIN OCCUR OVER MUCH OF THE ROCKIES AS LOW/MID LEVEL MOISTURE
   TRAPPED UNDER THE UPPER RIDGE AND OROGRAPHIC FORCING SUPPORT SCT
   CONVECTION. A FEW DRY TSTMS WILL BE POSSIBLE ALONG THE WRN/NWRN EDGE
   OF THIS MOISTURE OVER THE ERN GREAT BASIN/NRN ROCKIES. AN INCREASING
   PRESSURE GRADIENT OVER THE NRN/CENTRAL PLAINS WILL SUPPORT MODERATE
   SLY WINDS.
   
   ...CRITICAL FIRE WEATHER AREA - SERN AL...SRN GA AND THE FLA
   PANHANDLE...
   
   PRIMARY CONDITIONS: SUSTAINED NLY WINDS FROM 15-20 MPH...MIN RH
   READINGS FROM 20-30 PERCENT...LONG TERM DROUGHT
   
   IN THE WAKE OF A COLD FRONT...NLY WINDS WILL INCREASE TO BETWEEN
   15-20 MPH OVER THE REGION DURING THE AFTERNOON AS A MID LEVEL FLOW
   STRENGTHENS AND LOW LEVEL LAPSE RATES STEEPEN. LACK OF WIDESPREAD
   MOD/HVY PRECIPITATION ON DAY ONE SHOULD KEEP THE AREA IN A VERY HIGH
   FIRE DANGER. WITH TEMPERATURES NEAR 80 DEG F AND DWPTS IN THE 40S
   MIN RH READINGS ARE EXPECTED TO BE AROUND 30 PERCENT. THE
   COMBINATION OF DRY AIR AND GUSTY WINDS WILL SUPPORT A CRITICAL FIRE
   WEATHER THREAT.
   
   ...NRN PLAINS...
   SLY WINDS WILL INCREASE TO BETWEEN 20-25 MPH OVER THE NRN PLAINS AS
   PRESSURE GRADIENT STRENGTHENS IN RESPONSE TO A LOW AMPLITUDE UPPER
   TROUGH MOVING THROUGH THE NRN ROCKIES. LACK OF MOISTURE RETURN WITH
   DWPTS IN THE 40S AND WARM TEMPERATURES IN THE 80S WILL SUPPORT MIN
   RH READINGS FROM 25-30 PERCENT...ABOVE CRITICAL LEVELS.
