   NWS STORM PREDICTION CENTER NORMAN OK
   0408 AM CDT MON APR 30 2007
   
   VALID 301200Z - 011200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A ZONAL PATTERN WILL CONTINUE TODAY ACROSS THE NRN TIER OF STATES
   NORTH OF A BROAD UPPER RIDGE. AN ACTIVE SRN STREAM WILL ALSO
   CONTINUE TODAY AS AN UPPER LOW MOVES ACROSS THE SRN PLAINS AND
   ANOTHER SYSTEM MOVES TOWARDS THE SRN CA COAST. SEVERAL AREAS OF NEAR
   CRITICAL FIRE WEATHER CONDITIONS WILL BE POSSIBLE TODAY DUE TO
   MODERATE WINDS AND/OR LOW RH READINGS.
   
   ...MID-ATLANTIC REGION...
   ALONG THE SRN EXTENT OF STRONGER MID LEVEL WINDS ALOFT ASSOCIATED
   WITH A NRN STREAM SHORTWAVE TROUGH MOVING THOUGH NEW
   ENGLAND...MODERATE NWLY WINDS WILL DEVELOP OVER THE REGION DURING
   THE AFTERNOON...WITH SUSTAINED SPEEDS FROM 15-25 MPH. WARM
   TEMPERATURES IN THE 70S WILL COMBINE WITH DEWPTS IN THE 40S TO
   PRODUCE MIN RH READINGS AROUND 35 PERCENT. LACK OF LOWER RH READINGS
   WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT.
   
   ...SERN STATES...
   VERY DRY AIR WILL AGAIN BE IN PLACE ACROSS THE AREA TODAY WITH MIN
   RH READINGS FROM 25-30 PERCENT. PRESENCE OF SFC HIGH PRESSURE NEAR
   THE REGION...WILL LIMIT SUSTAINED WINDS TO LESS THAN 10 MPH. 
   
   ...NRN PLAINS...
   BEHIND ANOTHER NRN STREAM SHORTWAVE TROUGH AND COLD FRONT...NWLY
   WINDS WILL AVERAGE FROM 20-25 MPH THIS AFTERNOON. TEMPERATURES IN
   THE 65-75 DEG F RANGE AND DEWPTS IN THE 30S/LOWER 40S WILL SUPPORT
   MIN RH READINGS FROM 25-35 PERCENT. THESE RH VALUES WILL BE JUST
   ABOVE CRITICAL LEVELS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0409 AM CDT MON APR 30 2007
   
   VALID 011200Z - 021200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A ZONAL UPPER FLOW PATTERN WILL UNDERGO AMPLIFICATION THROUGHOUT THE
   PERIOD AS A DEEP UPPER LOW/TROUGHING OVER THE GULF OF ALASKA
   DEVELOPS SEWD TOWARDS THE PAC NW COAST. MEANWHILE...A SRN STREAM
   UPPER LOW WILL MOVE THROUGH THE SOUTHWEST. ASSOCIATED WITH THIS
   SYSTEM...ISOLATED DRY TSTMS ARE EXPECTED TO DEVELOP OVER PORTIONS OF
   THE SOUTHWEST AND SRN GREAT BASIN. COVERAGE OF DRY TSTMS IN THIS
   REGION MAY BE CLOSE TO CRITICAL LEVELS. ASSOCIATED WITH DEEPENING
   UPPER TROUGH OFF THE PAC NW...SWLY WINDS WILL INCREASE OVER THE NRN
   GREAT BASIN AND NRN ROCKIES/NRN HIGH PLAINS S AN AREA OF LOW
   PRESSURE DEEPENS OVER WRN MT.
   
   ...NRN GREAT BASIN...
   SWLY WINDS WILL INCREASE OVER THE REGION AHEAD A COLD FRONT AND
   ASSOCIATED DEEPENING AREA OF LOW PRESSURE OVER THE NRN ROCKIES. 
   SUSTAINED SWLY WINDS WILL AVERAGE FROM 15-25 MPH. MARGINAL FIRE
   DANGERS DUE TO THE ANNUAL GREEN-UP OVER THE LOWER ELEVATIONS AND
   MARGINALLY LOW RH READINGS AROUND 15 PERCENT WILL PRECLUDE A
   CRITICAL FIRE WEATHER THREAT.
   
   ...SRN GREAT BASIN/SOUTHWEST...
   AHEAD OF A SRN STREAM UPPER TROUGH...MID LEVEL FORCING/MOISTURE WILL
   INCREASE. FCST SOUNDINGS INDICATE A DEEPLY MIXED BOUNDARY LAYER TO
   AROUND 600 MB ABOVE WHICH EXISTS ELEVATED INSTABILITY. GIVEN A
   MODERATE AMT OF FORCING AND COOLING ALOFT ASSOCIATED WITH THIS
   SYSTEM THERE EXISTS THE POTENTIAL OF A CRITICAL DRY THUNDERSTORM
   EVENT. AREA WILL BE MONITORED FOR A POSSIBLE UPGRADE IN TOMORROW/S
   OUTLOOK.
   
   ...NRN PLAINS...
   INCREASING SFC PRESSURE GRADIENT DUE TO A DEEPENING AREA OF LOW
   PRESSURE OVER WRN MT WILL SUPPORT SUSTAINED SELY WINDS FROM 20-25
   MPH. DESPITE MILD TEMPERATURES IN THE 70S TO LOWER 80S...SLOWLY
   INCREASING LOW LEVEL MOISTURE WILL KEEP MIN RH READINGS ABOVE 25
   PERCENT FOR MOST OF THE AFTERNOON.
   
   ...SOUTHEAST...
   UNDER THE PRESENCE OF WEAK UPPER RIDGING ALOFT...ANOTHER DAY OF LOW
   RH /20-30 PERCENT/ READINGS WILL OCCUR GIVEN LOW DWPTS AND WARM SFC
   TEMPERATURES IN THE UPPER 80S/LOWER 90S. LIGHT WINDS WILL PRECLUDE A
   CRITICAL FIRE WEATHER OUTLOOK AREA.
