DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0310 AM CDT THU MAR 20 2008
VALID 201200Z - 211200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR TX AND OK PANHANDLES
INTO EXTREME SWRN KS...
...CRITICAL FIRE WEATHER AREA FOR SRN AND ERN NM...WRN TX...WRN
OK...SWRN KS...
...SYNOPSIS...
A LOW AMPLITUDE UPPER TROUGH WILL CONTINUE TO ADVANCE EWD ACROSS THE
WRN STATES...NOSING INTO THE CNTRL HIGH PLAINS BY 00Z. AT THE
SURFACE...LOW PRESSURE WILL DEEPEN OVER WRN NEB AND KS...WITH A
SURFACE TROUGH EXTENDING SWWD INTO ERN NM. A STRENGTHENING PRESSURE
GRADIENT WILL COMBINE WITH VERY LOW RH VALUES ACROSS THE SRN PLAINS
FOR A CRITICAL FIRE THREAT TODAY.
TO THE E...HIGH PRESSURE WILL SPREAD SEWD INTO THE SERN AND MID
ATLANTIC STATES IN THE WAKE OF A COLD FRONT. LOW RH AND GUSTY WINDS
WILL OCCUR FROM VA/NC SWD INTO NRN FL...PRODUCING A LARGE AREA OF
BORDERLINE CRITICAL FIRE CONDITIONS.
...EXTREMELY CRITICAL FIRE WEATHER AREA - TX AND OK PANHANDLES INTO
EXTREME SWRN KS...
PRIMARY CONDITIONS: VERY STRONG WINDS AND LOW HUMIDITY...WARM
TEMPERATURES AND DROUGHT
THE COMBINATION OF STRONG WINDS...VERY LOW RH...WARM TEMPERATURES
AND DROUGHT WILL CREATE AN EXTREMELY CRITICAL FIRE SITUATION.
THE STRONGEST WINDS WILL EXTEND FROM EXTREME ERN NM ACROSS THE OK
AND TX PANHANDLES AS WELL AS FAR SW KS...WHERE SUSTAINED SPEEDS NEAR
30 MPH ARE EXPECTED. HIGHER GUSTS TO 45 MPH ARE LIKELY AS WELL
DURING THE PEAK HEATING HOURS WHEN MIXING AND TURBULENCE IS
GREATEST. IT WILL BE A VERY WARM DAY WITH HIGH TEMPERATURES IN THE
UPPER 70S TO LOWER 80S. THIS WILL RESULT IN VERY LOW RH VALUES FROM
THE SINGLE DIGITS INTO THE LOWER TEENS.
GUSTY SWLY WINDS WILL PERSIST WELL INTO THE EVENING AND EARLY
MORNING HOURS...WITH ONLY MODERATE RH RECOVERY OVERNIGHT.
...CRITICAL FIRE WEATHER AREA - SRN AND ERN NM...WRN TX...WRN
OK...SWRN KS...
PRIMARY CONDITIONS: STRONG WINDS AND LOW RH
STRONG HEATING OF A VERY DRY AIR MASS WILL RESULT IN CRITICALLY LOW
RH VALUES IN THE SINGLE DIGITS AND TEENS OVER A LARGE PORTION OF THE
SRN PLAINS. AS A LOW PRESSURE TROUGH DEEPENS TODAY...WINDS WILL
INCREASE WITH THE STRONGEST GUSTS DURING THE AFTERNOON. SUSTAINED
SWLY WINDS AROUND 20 MPH WILL BE COMMON FOR SRN NM AND SWRN
TX...INCREASING TO 20-30 MPH OVER NERN NM AND SWRN KS WITH HIGHER
GUSTS OF 30-40 MPH ESPECIALLY CLOSE TO THE EXTREMELY CRITICAL AREA.
IN ADDITION TO THE STRONG WINDS AND LOW RH...LOW LEVEL LAPSE RATES
WILL BE STEEP WITH DEEP MIXING LAYERS FAVORABLE FOR FIRE GROWTH.
...VA INTO NC...
A MODERATELY STRONG PRESSURE GRADIENT WILL REMAIN IN THE WAKE OF THE
COLD FRONT PASSAGE...AND WILL RESULT IN NWLY WINDS OF 15-25 MPH WITH
HIGHER GUSTS. TEMPERATURES WILL BE SOMEWHAT COOL...WITH HIGHS
RANGING FROM THE UPPER 50S OVER MD TO THE MID 60S INTO NC...BUT RH
WILL STILL DROP INTO THE 20 PERCENT RANGE. THE MAIN MITIGATING
FACTOR TO THE FIRE THREAT TODAY IS THE RAIN THAT FELL WITH THE COLD
FRONT. HOWEVER...LOCALIZED AREAS THAT RECEIVED MINIMAL RAINFALL WILL
EXPERIENCE CRITICAL FIRE CONDITIONS.
...SC...GA AND NRN FL...
A DRY AREA OF HIGH PRESSURE WILL CONTINUE TO SPREAD ACROSS THE SERN
STATES WITH CRITICALLY LOW RH WIDESPREAD. WIND SPEEDS WILL BE WEAKER
IN THIS AREA THAN FARTHER N...WITH SUSTAINED NWLY WINDS AROUND 15
MPH ALTHOUGH GUSTS TO AROUND 20 WILL BE POSSIBLE. LOW KBDI VALUES
AND RECENT PRECIPITATION LAST NIGHT AND EARLY THIS MORNING SUGGEST
THAT FUELS MAY NOT BE PRIMED FOR A LARGE SCALE CRITICAL THREAT.
...MUCH OF OK INTO NRN AND CNTRL TX...
VERY STRONG SLY WINDS WILL MATERIALIZE TODAY AS LOW PRESSURE DEEPENS
TO THE NW. SUSTAINED SLY WINDS WILL RANGE FROM 15-20 MPH OVER CNTRL
TX TO AROUND 30 MPH OVER MUCH OF OK...WITH HIGHER GUSTS. WHILE RH
LEVELS WILL BE MODERATELY LOW...RANGING FROM 20-30 PERCENT...RECENT
PRECIPITATION HAS WET FUELS ENOUGH TO REDUCE THE FIRE THREAT IN THE
SHORT TERM.
...DEEP S TX...
IT WILL BE VERY DRY AND WARM TODAY WITH A SURFACE HIGH PRESSURE AXIS
OVERHEAD. MIN RH SHOULD RANGE FROM THE TEENS NEAR THE RIO GRANDE TO
THE 30 PERCENT RANGE ALONG THE COAST...DESPITE LIGHT ONSHORE FLOW OF
10-15 MPH. THIS SHOULD MAINTAIN A MARGINAL FIRE THREAT THIS
AFTERNOON.
...ERN AZ INTO WRN NM...
DEEP WLY TROPOSPHERIC FLOW WILL INCREASE TODAY WITH BASE OF THE
UPPER TROUGH OVER THE FOUR CORNERS AREA BY 00Z. WLY WINDS WILL
INCREASE TO NEAR 20 MPH OVER MUCH OF NRN AZ INTO NWRN NM...WITH
HIGHER GUSTS ESPECIALLY NEAR RIDGE TOPS. DESPITE RELATIVELY COOLER
TEMPERATURES IN THE 60S...OVER NRN AZ/NM...RH WILL STILL DROP INTO
THE 10-15 PERCENT RANGE FOR A MARGINAL FIRE THREAT. SERN AZ AND SWRN
NM WILL EXPERIENCE WARMER CONDITIONS...BUT SUSTAINED WINDS SHOULD BE
A BIT LESS...AVERAGING 15-20 MPH AND GUSTY.
...SERN WY/WRN NEB...
LOW PRESSURE WILL DEEPEN OVER NWRN NEB AND WINDS WILL SHIFT TO A WLY
DIRECTION BEHIND THIS LOW. SUSTAINED WLY WINDS NEAR 20 MPH WILL
OCCUR WITH HIGHER GUSTS...BUT TEMPERATURES WILL ONLY BE IN THE 50S
WITH MIN RH 20-30 PERCENT. LIFT WITH THE UPPER TROUGH AND A STEEP
LAPSE RATE ENVIRONMENT MAY RESULT IN SOME HIGH BASED
CONVECTION...PRODUCING A FEW LIGHTNING STRIKES BUT LITTLE RAIN.

...SYNOPSIS...
A LOW AMPLITUDE UPPER TROUGH WILL MOVE EWD ACROSS THE UPPER MS
VALLEY...WITH A COLD FRONT EXTENDING SWWD INTO OK AND NWRN TX BY
AFTERNOON. BEHIND THIS FRONT...WINDS WILL SHIFT TO NLY WITH DRY
CONDITIONS CONTINUING FOR THE SRN HIGH PLAINS. TO THE E...HIGH
PRESSURE CENTER WILL MOVE OFFSHORE BY MIDDAY...BUT AN EXPANSIVE ZONE
OF LOW HUMIDITY WILL REMAIN FOR THE SERN QUARTER OF THE U.S.
...CNTRL AND SRN HIGH PLAINS...
A WEAK COLD FRONT WILL MOVE SWD...SETTLING ACROSS CNTRL AND SWRN TX
BY LATE IN THE DAY. WINDS WILL SHIFT TO NLY AT 15-20 MPH WHILE

AND 70S CNTRL TX. RH LEVELS WILL BE MODERATELY LOW...AVERAGING NEAR
20 PERCENT.
...SERN STATES...
HIGH PRESSURE CENTER WILL SHIFT OFFSHORE BUT ITS AFFECTS WILL REMAIN
IN THE FORM OF SEVERAL HOURS OF 20-30 PERCENT RH. WINDS WILL SWITCH

WITH HIGHER GUSTS. LOCALLY CRITICAL CONDITIONS MAY THUS OCCUR IN
AREAS THAT HAVE THE DRIEST FUELS.
