   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0254 AM CDT MON MAY 18 2009
   
   VALID 181200Z - 191200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A LARGE UPPER RIDGE WILL BE CENTERED OVER THE FOUR CORNERS AND WILL
   MOVE SLOWLY EWD...EXTENDING FROM THE GREAT BASIN INTO THE HIGH
   PLAINS BY AFTERNOON. VERY WARM WEATHER WILL EXIST UNDER THIS
   RIDGE...WITH GUSTY WINDS BEGINNING TO DEVELOP OVER OREGON AND THE
   NRN GREAT BASIN. ISOLATED DRY THUNDERSTORMS ARE LIKELY FROM THE
   MOGOLLON RIM OF AZ INTO THE SRN SIERRA...AS MOISTURE STREAMS NWD
   AROUND THE WRN EDGE OF THE RIDGE. A MIXTURE OF WET AND DRY STORMS
   WILL OCCUR OVER WRN MT WITHIN A PRE-FRONTAL TROUGH.
   
   ELSEWHERE...STRONG SWLY WINDS WILL EXIST FROM THE CNTRL PLAINS INTO
   THE UPPER MS VALLEY AS A LOW DEEPENS OVER SD. DRY AIR OUT OF THE ERN
   SFC HIGH WILL RESULT IN MODERATELY LOW RH FOR MN AND WI...AND THUS
   NEAR CRITICAL FIRE CONDITIONS WHERE FUELS ARE DRIEST. FINALLY...DRY
   NELY WINDS OUT OF THE SAME HIGH WILL BRING DOWN RH LEVELS ACROSS THE
   GULF COAST STATES...N OF A STALLED FRONT WHICH WILL BRING
   PRECIPITATION TO FL AND THE SE COAST.
   
   ...MN/WI/NRN MI...
   A STRONG PRESSURE GRADIENT WILL FORM LATER TODAY BETWEEN HIGH
   PRESSURE TO THE E AND A LOW DEEPENING OVER SD. SUSTAINED SW WINDS OF
   20-25 MPH ARE LIKELY WITH GUSTS OVER 30 MPH. RELATIVELY LESS RAIN
   HAS FALLEN ACROSS CNTRL MN INTO NWRN WI OVER THE PAST FEW WEEKS AS
   COMPARED TO AREAS FARTHER S. THIS...ALONG WITH MARGINALLY LOW RH
   VALUES OF 25 TO 35 PERCENT...SUGGEST BORDERLINE CRITICAL
   CONDITIONS...ESPECIALLY WHERE FUELS HAPPEN TO BE DRIEST.
   
   ...NRN CA/SERN ORE/SW ID/NRN NV...
   A THERMAL TROUGH WILL DEEPEN OVER ERN WA/ORE BY AFTERNOON WITH AN
   UPPER RIDGE SLOWLY BREAKING DOWN AHEAD OF THE NEXT TROUGH. IT WILL
   BE QUITE WARM WITH HIGH TEMPERATURES IN THE 90S F AND MIN RH IN THE
   SINGLE DIGITS TO TEENS AREAWIDE. SUSTAINED WLY WINDS ARE NOT
   EXPECTED TO EXCEED 20 MPH...ALTHOUGH HIGHER GUSTS MAY OCCUR.
   
   ...CA SIERRA INTO CNTRL AZ...
   ISOLATED DRY THUNDERSTORMS WILL BE LIKELY THIS AFTERNOON...MAINLY
   OVER THE MTNS...AS MID LEVEL MOISTURE INCREASES OUT OF THE S. UPPER
   LEVEL WIND FIELDS WILL BE WEAK UNDER THE RIDGE...THUS STORMS SHOULD
   NOT MOVE MUCH AND MAY RESULT IN MEASURABLE RAIN. STILL...LIGHTNING
   IGNITION EFFICIENCY MAY BE HIGH GIVEN A DRY SUB-CLOUD LAYER.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0416 AM CDT MON MAY 18 2009
   
   VALID 191200Z - 201200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR ERN CO...SW NEB...WRN KS...NERN
   NM...WRN OK/TX PANHANDLES...
   ...CRITICAL FIRE WEATHER AREA FOR FL PANHANDLE...SRN GA...FAR SE
   AL...
   
   ...SYNOPSIS...
   A LARGE UPPER RIDGE WILL BE CENTERED OVER THE CNTRL PLAINS ON
   TUE...SHUNTED EWD BY A STRONG UPPER TROUGH ACROSS THE NWRN STATES.
   THIS TROUGH WILL BRING STRONG WINDS AND SCATTERED DRY THUNDERSTORMS
   TO ORE/ID/NV.  ADDITIONAL AFTERNOON STORMS WILL OCCUR ACROSS UT/NRN
   AZ AND CO.  TO THE E...STRONG SWLY WINDS AND LOW RH WILL RESULT IN
   CRITICAL CONDITIONS FOR THE CNTRL HIGH PLAINS...WITH AREAS OF LOW RH
   AND GUSTY WINDS FOR MS/AL/GA ON THE S SIDE OF THE HIGH...AND N OF A
   CUT-OFF LOW.
   
   ...CRITICAL FIRE WEATHER AREA - ERN CO...SW NEB...WRN KS...NERN
   NM...WRN OK/TX PANHANDLES...
   
   PRIMARY CONDITIONS: STRONG WINDS AND LOW RH
   
   A LOW PRESSURE TROUGH WILL DEEPEN DURING THE AFTERNOON FROM ERN MT
   INTO ERN CO...WELL AHEAD OF AN UPPER TROUGH AND WITHIN A VERY WARM
   AND DRY AIR MASS. SW WINDS WILL INCREASE TO 20-30 MPH WITH HIGHER
   GUSTS ESPECIALLY OVER ERN CO AND WRN KS. RH WILL BE LOWEST FROM WRN
   NEB INTO ERN CO AND NERN NM...WITH VALUES DIPPING INTO THE UPPER
   SINGLE DIGITS AND LOWER TEENS. RH WILL GRADUALLY RECOVER BY MORNING
   WITH GUSTY WINDS PERSISTING OVERNIGHT.
   
   ...CRITICAL FIRE WEATHER AREA - FL PANHANDLE...SRN GA...FAR SE AL...
   
   PRIMARY CONDITIONS: STRONG NE WINDS...LOW RH
   
   AN AREA OF DRY HIGH PRESSURE WILL BE SITUATED OVER THE MID ATLANTIC
   REGION ON TUESDAY...WITH DRY NELY WINDS ACROSS THE GULF COAST
   INCLUDING N FL. RECENT RAINS HAVE INCREASED FUEL MOISTURE IN
   SPOTS...BUT NOT ALL AREAS RECEIVED SIGNIFICANT
   PRECIPITATION...NAMELY PORTIONS OF SW AND S CNTRL GA...AND THE CNTRL
   AND ERN FL PANHANDLE. NELY WINDS SUSTAINED AT 20 MPH WILL BE COMMON
   WITH HIGHER GUSTS OF 20-30 MPH ACROSS SRN AL...GA...AND THE FL
   PANHANDLE. MIN RH WILL DROP INTO 20 PERCENT RANGE BY AFTERNOON WITH
   TEMPERATURES IN THE 70S F. THE SERN EDGE OF THE CRITICAL AREA ACROSS
   N FL MAY HAVE TO BE ADJUSTED IN NEXT DAY 1 OUTLOOK DUE TO EXPECTED
   LOCATION OF HEAVY RAINS ON TUE.
   
   ...SE ORE...NE CA...NW NV...SW ID...
   LOW PRESSURE WILL DEEPEN OVER SE ORE AND SW ID AHEAD OF A COLD FRONT
   AS A POTENT UPPER TROUGH SHIFTS EWD OVER THE PACIFIC NW. SWLY WINDS
   OF 20-30 MPH WITH HIGHER GUSTS WILL BE LIKELY...WITH RH IN THE
   TEENS. IN ADDITION...ISOLATED TO SCATTERED DRY THUNDERSTORMS ARE
   EXPECTED OVER FAR ERN ORE INTO CNTRL AND SW ID AS WELL AS NRN AND
   CNTRL NV. THE MITIGATING FACTOR IN THIS CASE WILL BE FUEL
   CONDITIONS...WHICH ARE NOT DRY ENOUGH FOR CRITICAL FIRE CONDITIONS
   PER COORDINATION WITH LOCAL FIELD OFFICES.
