   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0115 AM CDT MON MAR 09 2009
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A SPLIT FLOW REGIME EXISTS OVER THE STATES THIS MORNING...WITH A
   SOUTHERN STREAM JET ALLOWING A MODIFIED PACIFIC AIRMASS TO
   OVERSPREAD MUCH OF THE SOUTHWESTERN STATES AND THE SOUTHERN
   PLAINS...WHILE A SECOND JET WILL ALLOW A WESTERN TROUGH TO DIG INTO
   THE CNTRL ROCKIES TODAY. THIS WILL DEEPEN A SURFACE LOW NEAR THE
   CO/KS BORDERS. SWLY/SLY SURFACE WINDS WILL INCREASE ACROSS MUCH OF
   THE SRN PLAINS...ALIGNING WITH MARGINAL RHS MAINLY NEAR THE TX/OK
   PANHANDLES AND SERN CO. WINDS WILL SLOWLY SHIFT TO WLY AHEAD OF A
   COLD FRONT.
   
   ...TX/OK PANHANDLES AND SERN CO...
   AS WAS PREVIOUSLY DISCUSSED...A SUBTROPICAL JET STREAM HAS ALLOWED
   FOR A MODIFIED PACIFIC AIRMASS TO OVERSPREAD MUCH OF THE SOUTHWEST
   AND THE SOUTHERN PLAINS. MEASURABLE PRECIPITATION HAS BEEN RECORDED
   OVER THE PAST FEW HOURS IN SRN AZ AND NM...AND AN INCREASE IN
   MOISTURE WILL SLOWLY SPREAD NEWD THROUGH THE DAY. CONSIDERABLE HIGH
   CLOUDINESS IS NOTED...AND WILL CONTINUE TO AFFECT THE REGION. THIS
   WILL LIMIT THE AMOUNT OF HEATING THAT CAN OCCUR THIS AFTERNOON...AND
   TEMPERATURES ARE ANTICIPATED TO REMAIN IN THE MID 60S TO LOWER 70S.
   CONSEQUENTLY...PREVIOUSLY FORECAST LOW RHS WILL BE DIFFICULT TO
   REACH. OVERALL RHS ARE ANTICIPATED TO BE MARGINAL/ABOVE
   CRITICAL...WITH THE LOWEST VALUES OF LOW TO MID 20S POSSIBLE NEAR
   THE TX/OK PANHANDLES...AND IN SERN CO. SHOULD BREAKS IN THE CLOUDS
   ALLOW MORE HEATING...CRITICALLY LOW RHS MAY BE MET. DESPITE MARGINAL
   RHS...STRONG WINDS ARE STILL ANTICIPATED FROM SERN NM NEWD INTO WRN
   TX/OK...SWRN KS...AND SERN CO. SUSTAINED SPEEDS NEAR 25 TO 35 MPH
   WITH GUSTS UP TO 50 MPH CAN BE ANTICIPATED...ALTHOUGH SPEEDS OF 20
   MPH WITH GUSTS TO 30 MPH WILL BE MORE LIKELY NEAR THE SURFACE
   LOW...JUXTAPOSED WITH AFOREMENTIONED MARGINAL RHS. WITH THE
   MARGINALITY OF ANTICIPATED RHS...THE CRITICAL HAS BEEN REDUCED TO A
   SEE TEXT. HOWEVER...GIVEN DROUGHT/ANTECEDENT DRYNESS...EVEN WITH
   MARGINAL/ABOVE CRITICAL RHS...STRONG WINDS MAY FURTHER DRY
   FUELS...WITH WINDS CONTRIBUTING TO RAPID SPREAD SHOULD THERE BE FIRE
   STARTS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0151 AM CDT MON MAR 09 2009
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH OVER THE CNTRL ROCKIES WILL INTENSIFY AND QUICKLY
   MOVE NEWD TOWARDS THE GREAT LAKES REGION. MEANWHILE A BROAD SURFACE
   LOW EXTENDING FROM SERN CO INTO ERN KS WILL RAPIDLY DEEPEN AND MOVE
   NEWD THROUGH WISCONSIN AND INTO NWRN ONTARIO BY THE END OF THE
   PERIOD. THIS WILL DRIVE A COLD FRONT SWD INTO CNTRL TX...WITH COOLER
   AND DRIER AIR FOLLOWING. DRY AND WINDY CONDITIONS MAY AFFECT
   PORTIONS OF NERN NM AND THE TX/OK PANHANDLES BEFORE THE FRONT PASSES
   AND WINDS BEGIN TO RELAX.
   
   MEANWHILE IN THE SOUTHEASTERN STATES...HIGH PRESSURE WILL
   PERSIST...WITH WARM AND DRY CONDITIONS AFFECTING THE REGION. WINDS
   WILL GENERALLY BE LIGHT.
   
   ...NERN NM AND THE TX/OK PANHANDLES...
   INITIALLY SWLY WINDS WILL SHIFT TO WLY AND INCREASE BY LATE
   MORNING/EARLY AFTERNOON AHEAD OF A COLD FRONT. SUSTAINED SPEEDS OF
   20 TO 30 MPH WITH GUSTS TO 40 MPH WILL BE POSSIBLE.
   HOWEVER...TEMPERATURES WILL REMAIN RELATIVELY COOL...ONLY REACHING
   IN THE LOW TO MID 60S. FURTHERMORE...CONSIDERABLE HIGH CLOUDINESS
   MAY LINGER BEFORE THE UPPER TROUGH CAN MOVE NEWD...AND MAY ALSO
   CONTRIBUTE TO LOWER TEMPERATURES AND CONSEQUENTLY MARGINAL RHS. IF
   THE HIGH CLOUDS CAN CLEAR THE AREA IN TIME ALLOWING FOR FURTHER
   WARMING...CRITICAL CONDITIONS MAY BE BRIEFLY MET. WINDS WILL SHIFT
   TO NWLY BY AFTERNOON/EVENING AS THE FRONT PASSES...AND TEMPERATURES
   WILL BEGIN TO FALL. MUCH COOLER BUT DRIER AIR WILL FOLLOW...AND RHS
   WILL BE SLOW TO RECOVER OVERNIGHT.
