   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0311 AM CDT WED SEP 20 2006
   
   VALID 201200Z - 211200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NRN AZ...EXTREME SRN UT AND
   EXTREME NWRN NM...
   ...CRITICAL FIRE WEATHER AREA FOR FAR NERN NM AND FAR SERN CO...
   
   ...SYNOPSIS...
   POTENT UPPER-LEVEL LOW ACROSS THE NRN GREAT BASIN WILL SLIDE SEWD
   REACHING THE CNTRL HIGH PLAINS THURSDAY MORNING. STRONG MID-LEVEL
   WINDS ALONG THE SRN FLANK OF THE TROUGH WILL SPREAD ACROSS THE FOUR
   CORNERS REGION TOWARDS THE OK/TX PANHANDLES. THIS WILL HELP RAPIDLY
   STRENGTHEN A SURFACE LOW OVER E-CNTRL CO THIS AFTERNOON. AN
   ASSOCIATED COLD FRONT WILL MARCH SEWD INTO CNTRL AZ/NRN NM BY THIS
   EVENING.
   
   ...CRITICAL FIRE WEATHER AREA - NRN AZ...EXTREME SRN UT AND EXTREME
   NWRN NM...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH / MODERATE TO SEVERE
   DROUGHT
   
   STRONG WLY WINDS WILL DEVELOP TODAY...AS A 35 TO 45 MPH LOW-LEVEL
   JET REMAINS ACROSS THE AREA THROUGH THE AFTERNOON. ALTHOUGH A COLD
   FRONT PASSAGE LATER THIS MORNING INTO EARLY AFTERNOON WILL LIMIT
   WARMING...STEEP LOW-LEVEL LAPSE RATES SHOULD STILL OCCUR WITH MAINLY
   CLOUD-FREE SKIES. DOWNWARD MOMENTUM TRANSPORT AFTER MID/UPPER-LEVEL
   TROUGH PASSAGE WILL ALSO AID IN MIXING STRONGER WINDS TOWARDS THE
   SURFACE. SUSTAINED WINDS WILL LIKELY REACH 25 TO 30 MPH WITH GUSTS
   AROUND 40 MPH. WITH A DRY AIR MASS ALREADY IN PLACE...DEW POINTS
   WILL REMAIN IN THE TEENS AND 20S. TEMPERATURES SHOULD WARM LITTLE
   AFTER COLD FRONT PASSAGE...BUT STILL HOLD IN THE 60S AND 70S IN THE
   AFTERNOON. THIS WILL LEAD TO MARGINALLY LOW RH VALUES AROUND 15
   PERCENT.
   
   ...CRITICAL FIRE WEATHER AREA - FAR NERN NM AND FAR SERN CO...
   
   PRIMARY CONDITIONS: LOW RH / MODERATE WINDS / SHORT-TERM DRYNESS
   
   A SMALL AREA OF CRITICAL CONDITIONS SHOULD OCCUR FOR A FEW HOURS
   LATE THIS AFTERNOON WHERE MARGINALLY LOW RH DEVELOPS IN CONJUCTION
   WITH MODERATE LOW-LEVEL WINDS. DEEP MIXING WITH STEEP LOW/MID-LEVEL
   LAPSE RATES WILL ALLOW TEMPERATURES TO WARM INTO THE UPPER 70S TO
   MIDDLE 80S AND HOLD DEW POINTS IN THE UPPER 20S AND 30S. THIS WILL
   LEAD TO RH VALUES AROUND 15 PERCENT. ALTHOUGH STRONGER LOW-LEVEL
   WINDS WILL LIKELY OCCUR FURTHER S...OWING TO PROXIMITY OF SURFACE
   LOW NEAR THE PALMER DIVIDE...SUSTAINED SPEEDS SHOULD REACH 20 MPH.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0427 AM CDT WED SEP 20 2006
   
   VALID 211200Z - 221200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR ERN NM...NWRN TX AND
   PANHANDLE...SWRN OK...
   
   ...SYNOPSIS...
   LOW PRESSURE WILL LIFT NEWD FROM WRN KS INTO THE UPPER MS RIVER
   VALLEY BY FRIDAY MORNING. ASSOCIATED DRY LINE/COLD FRONT WILL PUSH
   EWD ACROSS THE SRN HIGH PLAINS. AN UPSTREAM MID-LEVEL SHORTWAVE WILL
   DIVE SWD...STRENGTHENING WINDS THROUGH THE PACIFIC NW INTO THE GREAT
   BASIN. SURFACE LOW PRESSURE WILL DEEPEN OUT AHEAD OF THIS FEATURE
   ACROSS THE SRN GREAT BASIN.
   
   ...CRITICAL FIRE WEATHER AREA - ERN NM...NWRN TX AND
   PANHANDLE...SWRN OK...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH / SHORT-TERM DRYNESS
   
   GUSTY WINDS SHOULD BE ONGOING ALONG THE LEE OF THE ROCKIES THURSDAY
   MORNING WITH A TIGHT SURFACE PRESSURE GRADIENT AND A STRONG
   LOW-LEVEL JET. AS DAYTIME HEATING ENSUES...SUSTAINED WLY WINDS OF 20
   TO 30 MPH SHOULD OCCUR FROM MID-MORNING THROUGH MID-AFTERNOON...WITH
   GUSTS NEAR 40 MPH. AS THE SURFACE LOW ACROSS WRN KS LIFTS
   NEWD...LOW-LEVEL WINDS WILL RELAX LATE IN THE DAY. TEMPERATURES
   SHOULD QUICKLY WARM INTO THE 70S TO AROUND 90. DEW POINTS WILL DROP
   FROM W TO E AS A DRY LINE/WEAK COLD FRONT MOVES EWD. RH VALUES
   SHOULD REACH 10 TO 15 PERCENT ALONG THE LEE OF ROCKIES...AND 15 TO
   20 PERCENT FURTHER E.
   
   ...NERN CA/WRN NV...
   WINDS WILL INCREASE THURSDAY AS A MID-LEVEL SHORTWAVE DROPS SWD
   SPREADING STRONG NWLY FLOW ACROSS THE AREA. SURFACE WINDS SHOULD
   EXCEED 20 MPH WITH GUSTS LIKELY AROUND 30 MPH DURING THE AFTERNOON.
   HOWEVER...MODEL FORECASTS INCREASE LOW/MID-LEVEL MOISTURE OUT AHEAD
   OF THIS WAVE...WITH STRONG LOW-LEVEL COOLING BEHIND IT. THUS...IT
   APPEARS SURFACE RH VALUES SHOULD REMAIN ABOVE 15 PERCENT AND
   PRECLUDE A CRITICAL THREAT.
   
   ...PORTIONS OF THE SRN CA COASTAL RANGE...
   SURFACE LOW PRESSURE SHOULD RAPIDLY STRENGTHEN ACROSS SRN NV/MOJAVE
   DESERT REGION DURING THE LATE AFTERNOON/EVENING ON THURSDAY...AHEAD
   OF THE UPSTREAM MID-LEVEL SHORTWAVE. THIS WILL LEAD TO AN INCREASING
   SURFACE PRESSURE GRADIENT AND GUSTY WINDS ACROSS THE ANTELOPE VALLEY
   AND NRN SLOPES OF THE COASTAL RANGE. GUSTS AROUND 25 MPH SHOULD
   SUPPORT POOR RH RECOVERY DURING THE EVENING...AND COULD LEAD TO
   BRIEF CRITICAL CONDITIONS.
