DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0256 AM CDT THU APR 09 2009
VALID 091200Z - 101200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR SERN NM...W CNTRL/N
CNTRL TX...SWRN OK...
...CRITICAL FIRE WEATHER AREA FOR SURROUNDING THE EXTREME IN SRN/ERN
NM...TX PANHANDLE...SWRN OK AND MUCH OF WRN/CNTRL TX...
...SYNOPSIS...
A STRONG VORTICITY MAXIMUM/LOW AND A 80 TO 90 KT MID LEVEL JET CORE
OVER CNTRL NM WILL BRIEFLY PHASE WITH AN UPPER LOW OVER CNTRL WY
BEFORE TRANSITIONING EWD INTO A CLOSED LOW OVER THE CNTRL KS/OK
BORDERS BY AFTERNOON. STRONG SWLY WINDS ALOFT AND A 50 TO 60 KT 700
MB JET WILL OVERSPREAD THE SRN PLAINS AS THIS OCCURS.
MEANWHILE AT THE SURFACE...A LOW OVER THE TX/OK BORDERS WILL SHIFT
EWD AS WELL...DEEPENING OVER N CNTRL OK AND PROGRESSING INTO THE MID
MS VALLEY BY FRI MORNING. EXTREMELY CRITICAL CONDITIONS WILL DEVELOP
ACROSS MUCH OF THE SRN PLAINS AHEAD OF A COLD FRONT AND BEHIND A
DRYLINE. AS THE COLD FRONT DIVES SWD...A WIND SHIFT WILL POSE A
THREAT TO ANY ONGOING FIRES. EVEN WITH THE FRONTAL PASSAGE...RHS
WILL BE SLOW TO RECOVER OVERNIGHT.
FARTHER E...ANOTHER DAY OF CRITICALLY LOW RHS WILL OCCUR ACROSS
INLAND PORTIONS OF THE FL PENINSULA.
...EXTREMELY CRITICAL FIRE WEATHER AREA - SERN NM...W CNTRL/N CNTRL
TX...SWRN OK...
PRIMARY CONDITIONS: VERY STRONG WINDS...LOW
RH...DROUGHT...ANTECEDENT DRYNESS
A SIGNIFICANT FIRE THREAT IS LIKELY FOR TODAY AS AN UPPER LOW MOVES
EWD INTO THE CNTRL KS/OK BORDERS DURING THE AFTERNOON AND A SURFACE
LOW DEEPENS OVER N CNTRL OK. AS THIS OCCURS...A STRONG 50 TO 60 KT
700 MB JET CORE WILL OVERSPREAD MUCH OF TX/OK. CURRENT VAD WIND
PROFILER DATA ACROSS ERN NM...SWRN/N CNTRL TX AND SRN OK INDICATE 50
TO 60 KT WLY/SWLY WINDS JUST OFF THE SURFACE. ALTHOUGH DIURNAL
COOLING/A NIGHTTIME INVERSION WILL TEMPORARILY LIMIT STRONGER
WINDS/GUSTS FROM REACHING THE SURFACE...WINDS WILL QUICKLY INCREASE
AFTER SUNRISE. STRONG SURFACE PRESSURE FALLS...ALREADY NOTED IN
CNTRL OK AND FAR S CNTRL KS...ARE INDICATIVE THAT THE SURFACE LOW
CURRENTLY IN SERN CO/SWRN KS WILL QUICKLY PROGRESS EWD...AND WINDS
THAT HAVE NOT ALREADY SHIFTED TO WLY WILL BEGIN TO SHIFT TO WLY
ACROSS A LARGE PORTION OF THE OUTLINED AREA. THE EXCEPTION WILL BE
IN THE IMMEDIATE VICINITY OF THE DRYLINE EXTENDING THROUGH CNTRL
OK/TX...WHERE SWLY WINDS OF 25 TO 35 MPH WITH GUSTS TO 45 MPH WILL
BE LIKELY...THOUGH THESE AREAS WILL SHIFT TO WLY BY LATE AFTERNOON
AS THE DRYLINE PROGRESSES EWD. W OF THE DRYLINE BUT AHEAD OF A COLD
FRONT...WLY WINDS OF 35 TO 45 MPH WILL BE COMMON. VERY DEEP MIXING
HEIGHTS...ESPECIALLY FROM SWRN OK SWWD INTO SERN NM/FAR SWRN
TX...WILL ALLOW STRONG GUSTS OF 50 TO 60 MPH. ISOLD VERY STRONG
GUSTS OF 70 MPH WILL BE POSSIBLE IN THESE AREAS...ESPECIALLY OVER
THE HIGHER TERRAIN OF SWRN TX. BY EARLY AFTERNOON/EVENING...NRN
PORTIONS OF THE EXTREMELY CRITICAL WILL ENCOUNTER A WIND SHIFT FROM
WLY TO NWLY AS A COLD FRONT MOVES SWD...POSING A THREAT TO ANY
EXISTING FIRES. THE FRONT WILL CONTINUE SOUTH THROUGH THE
EVENING...MOVING THROUGH THE REMAINDER OF THE EXTREME OVERNIGHT.
AN EXTREMELY DRY AIRMASS WILL ALLOW TEMPERATURES TO REACH INTO THE
UPPER 80S ACROSS SRN PORTIONS OF THE EXTREME AREA...AND INTO MID TO
UPPER 70S ACROSS THE N. RHS IN THE UPPER TEENS CAN BE EXPECTED
CLOSER TO THE DRYLINE...WHILE W OF THESE AREAS SINGLE DIGITS WILL BE
COMMON. RHS WILL BE SLOW TO RECOVER OVERNIGHT. FURTHERMORE...DROUGHT
AND ANTECEDENT DRYNESS HAS VERY LIKELY PRECONDITIONED FUELS...AND
WILL COMBINE WITH AFOREMENTIONED CONDITIONS FOR A VERY DANGEROUS
FIRE THREAT TODAY.
...CRITICAL FIRE WEATHER AREA - SURROUNDING THE EXTREME IN SRN/ERN
NM...TX PANHANDLE...SWRN OK AND MUCH OF WRN/CNTRL TX...
PRIMARY CONDITIONS: STRONG WINDS...LOW RH...DROUGHT...ANTECEDENT
DRYNESS
SURROUNDING THE EXTREMELY CRITICAL THERE WILL BE A HEIGHTENED FIRE
THREAT. ON THE WRN EDGE...INITIALLY STRONG WINDS IN SWRN NM WILL
WEAKEN THROUGH THE DAY....THOUGH TEMPERATURES IN THE MID 60S/LOWER
70S AND RHS IN THE TEENS WILL ALIGN WITH 20 TO 30 MPH WINDS BY
AFTERNOON. ALONG THE NRN PORTION OF THE CRITICAL...TEMPERATURES WILL
BE COOLER COMPARED TO AREAS TO THE S AS A COLD FRONT ADVANCES FROM
THE N...BUT WILL LIKELY REACH INTO THE 60S ACROSS THE PANHANDLE. RHS
IN THE TEENS AND LOWER 20S WILL ALIGN WITH 25 TO 35 MPH WINDS...WITH
A RAPID SHIFT FROM WLY TO NWLY WINDS IN THE AFTERNOON. ALONG ERN
PORTIONS OF THE CRITICAL...WINDS WILL BE STRONG AND TEMPERATURES
WILL BE WARM...BUT RHS WILL BE MARGINAL COMPARED TO AREAS TO THE W.
THE STRENGTH OF THE WINDS WILL STILL POSE A SIGNIFICANT THREAT. IN
AREAS TO THE S...TEMPERATURES WILL BE MUCH WARMER...BUT WINDS WILL
BE LIGHTER.
...FLORIDA...
HIGH PRESSURE E OF THE BAHAMAS WILL CONTINUE TO SLOWLY RETURN
MOISTURE TO FL IN GENERALLY SLY/SWLY WINDS AROUND THE PERIPHERY OF
THE HIGH. 05Z SURFACE ANALYSIS REVEALS 50S DEW POINTS JUST BEGINNING
TO MOVE INTO THE IMMEDIATE W COAST OF FL AND TO THE PANHANDLE. SLY
WIND DIRECTION WILL SOMEWHAT IMPEDE PROGRESSION OF MOISTURE TO
INLAND PORTIONS OF THE FL PENINSULA...AND ANOTHER DAY OF CRITICALLY
LOW RHS IN THE UPPER 20S TO LOWER 30S WILL BE LIKELY ACROSS THESE
AREAS AS TEMPERATURES REACH INTO THE UPPER 70S AND LOWER 80S.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0333 AM CDT THU APR 09 2009
VALID 101200Z - 111200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
A PROGRESSIVE PATTERN WILL CONTINUE AS ANOTHER UPPER LOW DIVES SEWD
INTO SRN CA/NRN BAJA CA...OVERSPREADING STRONG SWLY WINDS ALOFT INTO
THE SWRN STATES ONCE AGAIN. STRONG WINDS AND MARGINAL RHS WILL BE
POSSIBLE ACROSS SRN AZ AS A SURFACE LOW FORMS TO THE N OVER THE ERN
GREAT BASIN...BUT CURRENT INDICATIONS ARE THAT PACIFIC MOISTURE WILL
QUICKLY MOVE NEWD AND LIMIT CRITICAL CONDITIONS IN THIS AREA.
FARTHER E...AN UPPER LOW AND ATTENDANT SURFACE LOW WILL QUICKLY MOVE
EWD FROM THE MID MS VALLEY TOWARDS THE MID ATLANTIC. THIS WILL DRIVE
A COLD FRONT SEWD INTO THE WRN GULF...THEN THROUGH MOST OF THE SERN
STATES...BEFORE STALLING ACROSS NRN FL. CRITICAL CONDITIONS ARE NOT
ANTICIPATED FOR THE CONUS.
