DAY 1 FIRE WEATHER OUTLOOK

0327 AM CDT MON MAY 12 2008
VALID 121200Z - 131200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR THE FLORIDA PENINSULA...
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR FAR SERN AZ...MUCH OF
NM...FAR W TX AND WRN OK PANHANDLE...
...CRITICAL FIRE WEATHER AREA FOR FAR SRN NV AND SERN CA...MUCH OF
AZ...NRN AND WRN NM...SRN UT...SRN CO...SWRN KS...W TX/OK
PANHANDLE...
...CRITICAL FIRE WEATHER AREA FOR SRN GA...FL PANHANDLE AND NRN
FL...FAR SERN AL...
...SYNOPSIS...
LOW PRESSURE WILL DEEPEN OVER THE CNTRL HIGH PLAINS AS AN UPPER
TROUGH DIGS INTO THE FOUR CORNERS AREA. THIS WILL RESULT IN
WIDESPREAD CRITICAL FIRE CONDITIONS FROM THE LOWER CO RIVER VALLEY
EWD INTO W TX. TO THE E...HIGH PRESSURE WILL BUILD EWD INTO THE MS
VALLEY AND GULF COAST STATES. A MODERATE PRESSURE GRADIENT WILL
EXIST BETWEEN THIS HIGH AND THE LOW PRESSURE OFF THE MID ATLANTIC
COAST...PRODUCING CRITICAL FIRE CONDITIONS FOR FL.
...EXTREMELY CRITICAL FIRE WEATHER AREA - THE FLORIDA PENINSULA...
PRIMARY CONDITIONS: VERY LOW RH...STRONG WINDS...HIGH HAINES INDEX
AN EXTREMELY VOLATILE FIRE WEATHER SITUATION IS LIKELY LATER TODAY
ACROSS THE CNTRL AND ERN FL PENINSULA.
A MUCH DRIER AIR MASS IS CURRENTLY MOVING INTO THE SERN U.S. WITH
HIGH PRESSURE. WINDS WILL INCREASE QUICKLY AFTER SUNRISE TO 15-20
MPH BY MIDDAY...WITH HIGHER GUSTS. AS TEMPERATURES WARM INTO THE MID
TO UPPER 80S...RH LEVELS WILL PLUMMET TO NEAR 20 PERCENT...WITH
LOCALIZED AREAS DIPPING INTO THE 15-20 PERCENT RANGE. THE
COMBINATION OF GUSTY WINDS AND VERY LOW HUMIDITY WILL RESULT IN THE
POTENTIAL FOR FAST MOVING AND INTENSE WILDFIRES. IN ADDITION...THE
WARM AND DRY AIR MASS WILL EXTEND THROUGH A DEEP LAYER...RESULTING
IN A HIGH HAINES INDEX. THERFORE...ANY ONGOING FIRES WILL EXPERIENCE
FAVORABLE CONDITIONS DURING THE AFTERNOON FIRE UPSCALE GROWTH.
...EXTREMELY CRITICAL FIRE WEATHER AREA - FAR SERN AZ...MUCH OF
NM...FAR W TX AND WRN OK PANHANDLE...
PRIMARY CONDITIONS: EXTREMELY LOW RH...VERY STRONG WINDS...HIGH
HAINES INDEX
A LOW PRESSURE TROUGH WILL DEEPEN OVER THE CNTRL AND SRN HIGH PLAINS
THIS AFTERNOON IN RESPONSE TO AN APPROACHING UPPER LEVEL TROUGH.
STRONG HEATING AND MIXING WILL COMBINE WITH A TIGHT PRESSURE
GRADIENT ACROSS THE PLAINS TO PRODUCE VERY STRONG WINDS FROM EXTREME
ERN AZ ACROSS NM AND INTO FAR WRN TX. MIN RH VALUES AS LOW AS 3-5
PERCENT ARE ANTICIPATED BY LATE AFTERNOON. SWLY WINDS WILL INCREASE
TO NEAR 30 MPH SUSTAINED...WITH GUSTS OVER 40 MPH. THE COMBINATION
OF STRONG WINDS...EXCEPTIONALLY LOW RH AND A HIGH HAINES INDEX WILL
RESULT IN EXTREME FIRE BEHAVIOR.
...CRITICAL FIRE WEATHER AREA - FAR SRN NV AND SERN CA...MUCH OF
AZ...NRN AND WRN NM...SRN UT...SRN CO...SWRN KS...W TX/OK
PANHANDLE...
PRIMARY CONDITIONS: STRONG WINDS AND LOW HUMIDITY
THE APPROACHING UPPER TROUGH WILL ALSO CAUSE INCREASED WINDS OF
20-30 MPH WITH HIGHER GUSTS THOROUGH THE CO RIVER VALLEY AS WELL AS
OVER NRN AZ. RH LEVEL IN GENERAL ARE EXPECTED TO AVERAGE FROM 10-15
PERCENT IN THESE AREAS...AND WITH A MODERATE HAINES INDEX.
JUST S OF A COLD FRONT...MIN RH NEAR 15 PERCENT IS LIKELY OVER FAR
SRN UT AS WELL AS SRN AND SERN CO. THE WINDIEST AREAS ALONG THE NRN
FRINGE OF THE OUTLOOK WILL BE OVER SRN CO...WITH SPEEDS OF 25-30 MPH
OUT OF THE SW.
FARTHER E INTO WRN TX AND WRN OK...THE EFFECTS OF RECENT
PRECIPITATION ON FUELS AS WELL AS HIGHER RH VALUES OF 15-25 PERCENT
WILL KEEP THE FIRE THREAT FROM BEING EXTREME...DESPITE VERY STRONG
WINDS OF 30-40 MPH.
...CRITICAL FIRE WEATHER AREA - SRN GA...FL PANHANDLE AND NRN
FL...FAR SERN AL...
PRIMARY CONDITIONS: LOW HUMIDITY AND GUSTY WINDS
NWLY WINDS NEAR 15 MPH ARE LIKELY ALONG WITH MIN RH IN THE 20
PERCENT RANGE AS THE SURFACE LOW CONTINUES TO SPIN OFFSHORE.
MARGINAL KBDI VALUES AROUND 400 SUGGEST A MODERATE FIRE THREAT THIS
AFTERNOON GIVEN THE LONG DURATION OF LOW RH AND GUSTY WINDS.
TEMPERATURES WILL RISE INTO THE LOWER 80S WITH DEEP MIXING LAYERS AS
WELL.
...NERN GA AND WRN SC...
STRONG NWLY WINDS OF 15-25 MPH WITH HIGHER GUSTS ARE LIKELY FROM ERN
GA INTO SC AS THE LOW SHIFTS E OF THE AREA. DRY WIND TRAJECTORIES
OUT OF HIGH PRESSURE WILL BRING RH LEVELS DOWN INTO THE 20-30
PERCENT RANGE AS WELL. THE COMBINATION OF WIND AND RH SHOULD ONLY
RESULT IN A MARGINAL FIRE THREAT THOUGH...GIVEN RECENT
PRECIPITATION.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0404 AM CDT MON MAY 12 2008
VALID 131200Z - 141200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR SRN NM AND FAR W TX...
...CRITICAL FIRE WEATHER AREA FOR SERN AZ...SRN NM AND SWRN TX...
...CRITICAL FIRE WEATHER AREA FOR LOWER CO RIVER VALLEY...
...CRITICAL FIRE WEATHER AREA FOR FL...
...SYNOPSIS...
AN UPPER TROUGH WILL CONTINUE SLOWLY EWD ACROSS THE SRN ROCKIES AND
SRN PLAINS...PRODUCING HIGH WINDS AND LOW RH FOR SRN NM AND SW TX.
NLY FLOW ON THE W SIDE OF THIS UPPER TROUGH WILL ALLOW STRONG NLY
WINDS TO DEVELOP ACROSS SRN NV...SERN CA AND SWRN AZ.
WINDS WILL SUBSIDE ACROSS THE SERN U.S. AS THE HIGH PRESSURE AXIS
MOVES OVERHEAD. THIS WILL MAINTAIN VERY DRY WEATHER FOR FL...BUT
WINDS WILL BE LIGHT.
...EXTREMELY CRITICAL FIRE WEATHER AREA - SRN NM AND FAR W TX...
PRIMARY CONDITIONS: VERY STRONG WINDS AND LOW RH
A STRONG UPPER TROUGH WILL REMAIN OVER THE REGION ON TUE...WITH A
VERY WARM AND DRY AIR MASS AS WELL OVER SRN NM AND SWRN TX.
SUSTAINED SWLY WINDS OF 25-35 MPH ARE LIKELY WITH HIGHER
GUSTS...ALONG WITH MIN RH OF 5-10 PERCENT. A HIGH HAINES INDEX
ENVIRONMENT WILL ALSO REMAIN...FURTHER ENHANCING THE SEVERITY OF THE
FIRE THREAT.
...CRITICAL FIRE WEATHER AREA - SERN AZ...SOUTH CENTRAL NM AND SWRN
TX...
PRIMARY CONDITIONS: STRONG WINDS AND LOW RH
SURROUNDING THE EXTREME AREA...MIN RH NEAR 15 PERCENT IS LIKELY OVER
SERN AZ ALONG WITH WINDS OF 20-25 MPH WITH HIGHER GUSTS. FARTHER E
INTO SWRN TX...MIN RH OF 10-15 PERCENT AND WINDS OF 20-25 MPH WITH
HIGHER GUSTS ARE LIKELY...AND THE HAINES INDEX SHOULD ONLY BE MDT.
...CRITICAL FIRE WEATHER AREA - LOWER CO RIVER VALLEY...
PRIMARY CONDITIONS: STRONG NLY WINDS AND LOW RH
NLY WINDS WILL INCREASE QUICKLY ON TUE WITH SUSTAINED SPEEDS OF
25-35 MPH. A VERY DRY AIR MASS WILL REMAIN IN PLACE WITH SINGLE
DIGIT RH DURING THE AFTERNOON.
...CRITICAL FIRE WEATHER AREA - FL...
PRIMARY CONDITIONS: LONG DURATIONS OF VERY LOW RH AND A HIGH HAINES
INDEX...ONGOING FIRES
HIGH PRESSURE WILL MOVE OVERHEAD PROVIDING VERY DRY BUT CALM
CONDITIONS ON TUE. TEMPERATURES SHOULD REACH THE MID 80S
AREAWIDE...WITH MIN RH OF 20-30 PERCENT. THE LONG DURATION OF LOW RH
WILL RESULT IN AN ELEVATED FIRE THREAT DURING THE
AFTERNOON...ALTHOUGH LACK OF WIND WILL HELP REDUCE THE TOTAL THREAT.
HOWEVER...A HIGH HAINES INDEX WILL BE IN PLACE DUE TO DEEP MIXING
LAYERS. GIVEN ONGOING FIRES AND EXTREME DRYNESS...WILL KEEP A
CRITICAL THREAT GOING INTO TUE.
