   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE GREAT BASIN FOR
   DRY THUNDERSTORMS...
   
   ...SYNOPSIS...
   UPPER RIDGE BUILDS OVER THE WRN STATES AS SHORT WAVE TROUGH MOVES
   FROM THE NRN PLAINS INTO THE GREAT LAKES REGION. A WEAK UPPER LOW
   ALONG THE CNTRL CA COAST EARLY THIS MORNING LIFTS SLOWLY NWD OVER
   THE RIDGE...BRINGING ISOLATED TO SCATTERED DRY THUNDERSTORMS TO
   PORTIONS OF THE GREAT BASIN THIS AFTERNOON. MODERATE NWLY WINDS AND
   A RELATIVELY DRY AIRMASS MOVE OVER THE NRN PLAINS IN THE WAKE OF THE
   AFOREMENTIONED SHORT WAVE TROUGH AND ASSOCIATED SURFACE COLD FRONT.
   
   A DRY AND WARM AIRMASS RESIDE OVER THE SRN PLAINS...WITH SURFACE
   HIGH PRESSURE THE PREDOMINANT WEATHER FEATURE IN THE EAST. LIGHT NLY
   FLOW WILL BRING FAIRLY LOW AFTERNOON RH TO PORTIONS OF THE
   SOUTHEAST...OTHERWISE THE REMAINDER OF THE EAST CAN EXPECT RATHER
   TRANQUIL FIRE WEATHER CONDITIONS TODAY.
   
   ...CRITICAL FIRE WEATHER AREA - CNTRL/NRN NV...SERN OR...EXTREME
   NERN CA...
   
   PRIMARY CONDITIONS: DRY THUNDERSTORMS
   
   WEAK UPPER LEVEL TROUGH ALONG THE CNTRL CA COAST MOVES SLOWLY NEWD
   TODAY. SUFFICIENT MID LEVEL MOISTURE AND SOLAR HEATING WILL PRODUCE
   ENOUGH INSTABILITY TO GENERATE ISOLATED TO SCATTERED MID TO LATE
   AFTERNOON THUNDERSTORMS. THE DEEP AND DRY SUB CLOUD LAYER SHOULD
   MINIMIZE RAINFALL...AND COMBINED WITH WEAK LARGE SCALE ASCENT
   ASSOCIATED WITH THE UPPER WAVE...RESULT IN AN ORGANIZED REGION OF
   DRY THUNDERSTORMS. SURFACE WINDS WILL BECOME STRONG...GUSTY...AND
   ERRATIC NEAR THUNDERSTORMS...AND SURFACE RH GENERALLY BETWEEN 10 TO
   15 PERCENT THIS AFTERNOON.
   
   ...NRN PLAINS...
   DRY AIR AND NWLY FLOW HAVE MOVED INTO THE NRN PLAINS FOLLOWING THE
   PASSAGE OF A COLD FRONT EARLY THIS MORNING. MINIMUM RH WILL FALL TO
   AROUND 20 TO 25 PERCENT OVER THE WRN DAKOTAS...WITH NWLY SURFACE
   WINDS BETWEEN 15 TO 25 MPH. THE RESULT IS MARGINAL CRITICAL FIRE
   WEATHER CONDITIONS ACROSS THE AREA THIS AFTERNOON. 
   
   ...SRN PLAINS...
   A WARM AND DRY AIRMASS IS OVER THE SRN PLAINS...WITH SURFACE DEW
   POINTS IN THE UPPER 40S TO LOWER 50S EXPECTED LATER TODAY. AS
   AFTERNOON TEMPERATURES CLIMB INTO THE LOWER TO MID 90S...RH WILL
   FALL INTO THE MID 20S. DESPITE THE DRY AIRMASS...SUSTAINED SURFACE
   WINDS SHOULD NOT EXCEED 15 MPH AND THEREFORE PRECLUDES A LARGE SCALE
   CRITICAL FIRE WEATHER THREAT.
   
   ...AL/GA/EXTREME NRN FL...
   NLY FLOW WILL ADVECT DRIER AIR INTO THE DEEP SOUTH DURING THE
   DAY...WITH DEW POINT TEMPERATURES FALLING STEADILY INTO THE MID 50S
   BY LATE AFTERNOON. AS HIGH TEMPERATURES PUSH 90 DEGREES...RH WILL
   BRIEFLY FALL TO ABOUT 30 PERCENT LATER TODAY. THE LIGHT NLY WINDS
   AND SHORT DURATION MINIMIZE THE OVERALL CRITICAL THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0430 AM CDT SAT JUL 08 2006
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER RIDGE OVER THE WRN U.S. BEGINS TO FLATTEN AS WEAK UPPER LOW
   MOVES FROM THE GREAT BASIN INTO THE NRN ROCKIES. THE EASTERN STATES
   REMAIN UNDER A LONGWAVE TROUGH...WITH SURFACE FLOW BECOMING MORE
   SWLY AS SURFACE HIGH SHIFTS EWD INTO THE WRN ATLANTIC. THE POTENTIAL
   EXISTS FOR A FEW MAINLY DRY THUNDERSTORMS IN THE GREAT BASIN ALONG
   THE INTERFACE OF DRIER PACIFIC AIR AND MID LEVEL MONSOONAL MOISTURE.
   
   ...GREAT BASIN/SERN OREGON...
   THE POTENTIAL EXISTS FOR A FEW DRY THUNDERSTORMS ALONG WRN PERIPHERY
   OF MID LEVEL MONSOONAL MOISTURE SUNDAY AFTERNOON. LARGE SCALE
   FORCING FOR ASCENT IS RELATIVELY WEAK SO EXPECT THUNDERSTORMS TO
   REMAIN PRIMARILY ISOLATED...ALTHOUGH ANY STORMS WOULD BE ACCOMPANIED
   BY ERRATIC WINDS AND LOW SURFACE RH IN THE MID TO UPPER TEENS.
   PRECIPITABLE WATER SHOULD INCREASE CONSIDERABLY JUST TO THE
   EAST...ENDING ANY DRY LIGHTNING THREAT.
   
   ...SRN AL/SRN GA/EXTREME NRN FL...
   RESIDUAL DRY AIR LINGERING OVER PORTIONS OF THE SOUTHEAST WILL LEAD
   TO ANOTHER DAY OF LOW AFTERNOON RH FALLING TO ABOUT 30 PERCENT.
   MAXIMUM TEMPERATURES WILL BE WARM AND REACH ABOUT 90...BUT SURFACE
   WINDS SHOULD BECOME ELY/SELY AT ONLY 5 TO 10 MPH. THE LIGHT SURFACE
   WINDS AND MARGINAL RH PRECLUDE A FIRE WEATHER THREAT AREA AT THIS
   TIME.
