   VALID 271200Z - 281200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A DEEP UPPER TROUGH EXTENDING THROUGH THE CENTRAL US WILL GRADUALLY
   SHIFT EWD TOWARDS THE MISSISSIPPI VALLEY...WHILE A SURFACE LOW WILL
   LIFT NEWD FROM THE GULF COAST THROUGH THE APPALACHIANS AND INTO THE
   ERN GREAT LAKES. HIGH PRESSURE WILL BUILD IN BEHIND...WITH
   STRENGTHENING NWLY FLOW ACROSS MUCH OF THE CENTRAL US. ANOTHER
   TROUGH OF LOW PRESSURE WILL BEGIN TO APPROACH THE PACIFIC
   NORTHWEST...WITH STRENGTHENING SOUTHWESTERLY WINDS ACROSS COASTAL
   AREAS. MEANWHILE IN THE SOUTHWESTERN STATES...WARM AND DRY
   CONDITIONS WILL CONTINUE...ALTHOUGH WINDS WILL GENERALLY BE WEAKER
   FOR SUNDAY.
   
   ...PORTIONS THE NRN AND CNTRL PLAINS...
   PRESSURE GRADIENT BETWEEN EXITING AREA OF LOW PRESSURE AND HIGH
   PRESSURE SHIFTING SEWD WILL ALLOW FOR NWLY WINDS OF NEAR 20 TO 25
   MPH ACROSS PORTIONS OF THE NRN AND CNTRL PLAINS. A JET AXIS DIGGING
   INTO THE BACK SIDE OF THE UPPER TROUGH WILL ALSO ALLOW FOR STRONGER
   WINDS TO MIX TO THE SURFACE AT PEAK DAYTIME HEATING. THE STRONGEST
   WIND JUXTAPOSED WITH THE LOWEST RH WILL MAINLY BE ACROSS PORTIONS OF
    ERN MT/WY/CO AND WRN SD/NEB WHERE TEMPERATURES ARE FORECAST TO RISE
   INTO THE UPPER 50S AND LOWER 60S. DESPITE THIS...RHS WILL BE
   MARGINAL WITH VALUES DROPPING INTO THE MID TO UPPER 20S. SOUTH OF
   THESE AREAS...WARMER TEMPERATURES AND LOWER RHS WILL BE
   COMMON...ALTHOUGH WINDS WILL BE MUCH WEAKER.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0136 AM CDT SUN APR 27 2008
   
   VALID 281200Z - 291200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A DEEP UPPER TROUGH WILL CONTINUE TO GRADUALLY MOVE EWD OVER THE ERN
   STATES WITH A SERIES OF SHORT WAVES ROTATING AROUND THE MAIN LOW. A
   SURFACE LOW NEAR THE ERN GREAT LAKES WILL EXIT NEWD THROUGH NEW
   ENGLAND AND INTO QUEBEC. STRONG WINDS WILL FOLLOW THIS SYSTEM OVER
   MUCH OF THE UPPER MISSISSIPPI VALLEY AND WRN GREAT LAKES. HIGH
   PRESSURE WILL SHIFT EWD INTO THE ROCKIES AS ANOTHER SHORT WAVE
   TROUGH APPROACHES THE PACIFIC NORTHWEST. AS THIS
   OCCURS...SOUTHWESTERLY FLOW WILL INCREASE ACROSS MUCH OF THE WEST.
   
   ...ERN NM/WRN TX...
   AS HIGH PRESSURE SHIFTS EWD INTO THE ROCKIES...THE UPPER RIDGE AXIS
   IS FORECAST TO WEAKEN SOMEWHAT...WITH A MORE WESTERLY FLOW ALOFT
   DEVELOPING OVER THE SWRN STATES AND WEAK LEE CYCLOGENESIS OCCURRING
   INVOF SERN CO/NERN NM/ AND THE TX/OK PANHANDLES. GFS SEEMS
   AGGRESSIVE IN THIS SCENARIO...WHILE OTHER MODELS SUCH AS THE
   ECM...NAM...AND SREF ENSEMBLES ARE LESS AGGRESSIVE IN THE DEEPENING
   OF THE LOW AND THE STRENGTH OF THE ASSOCIATED SWLY SURFACE WINDS
   ACROSS ERN NM AND WRN TX. EVEN WITH THE GFS...WINDS APPEAR TO BE
   BORDERLINE OR JUST ABOVE CRITICAL VALUES. ALTHOUGH TEMPERATURES WILL
   EASILY WARM INTO THE MID TO UPPER 70S AND LOWER 80S WITH RELATIVE
   HUMIDITIES IN SINGLE DIGITS AND TEENS...UNCERTAINTY IN THE STRENGTH
   OF THE FORECAST WINDS WILL PRECLUDE ANY CRITICAL AREA DESIGNATION AT
   THIS TIME.
