NWS STORM PREDICTION CENTER NORMAN OK
0338 AM CDT THU MAY 01 2008
VALID 011200Z - 021200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR PORTION OF SRN/ERN
NM...WRN TX...
...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE SRN ROCKIES AND
SRN HIGH PLAINS...
...CRITICAL FIRE WEATHER AREA FOR NRN/CENTRAL FLA...
...SYNOPSIS...
A STRONG UPPER TROUGH WILL MOVE FROM THE ROCKIES INTO THE PLAINS
THROUGH TONIGHT. ASSOCIATED WITH THIS SYSTEM...A STRONG COLD FRONT
WILL MOVE SWD THROUGH THE CENTRAL PLAINS TODAY. SOUTH OF THIS FRONT
AND TO THE WEST OF A DRYLINE EXTENDING FROM CENTRAL OK SWD INTO
WCENTRAL TX...CRITICAL FIRE WEATHER CONDITIONS WILL BE WIDESPREAD
OVER THE SRN ROCKIES/SRN HIGH PLAINS REGION. BETWEEN A DEEPENING
AREA OF SFC LOW PRESSURE OVER THE CENTRAL PLAINS AND HIGH PRESSURE
OVER THE ERN SEABOARD AN INCREASING PRESSURE GRADIENT WILL SUPPORT
MODERATE TO STRONG SLY WINDS FROM THE LOWER PLAINS EWD INTO THE MS
VALLEY TODAY. LOW RH READINGS COMBINED WITH INCREASING WINDS WILL
SUPPORT NEAR CRITICAL FIRE WEATHER CONDITIONS OVER PORTIONS OF THE
SRN APPALACHIAN REGION. MODERATE ELY WINDS AND LOW RH READINGS WILL
CONTINUE OVER NRN/CNTRL FLA SUPPORTING ANOTHER DAY OF CRITICAL FIRE
WEATHER CONDITIONS.
...EXTREMELY CRITICAL FIRE WEATHER AREA - SRN/ERN NM...WRN TX...
PRIMARY CONDITIONS: SUSTAINED WLY WINDS FROM 30-35 MPH WITH GUSTS
OVER 50 MPH...MIN RH READINGS FROM 5-10 PERCENT...COLD FRONTAL
PASSAGE...LONG TERM DROUGHT
SOUTH OF A COLD FRONT AND ALONG THE CORRIDOR OF STRONGEST MID LEVEL
WINDS...STRONG WLY SFC WINDS /30-35 MPH WITH GUSTS OVER 50 MPH/ WILL
BE PREVALENT FROM SRN/ERN NM INTO WESTERN TX. WELL ABOVE NORMAL
TEMPERATURES COMBINED WITH LONG TERM DROUGHT ENHANCED LOW DEWPTS
/SINGLE DIGITS/ WILL SUPPORT MIN RH READINGS FROM 5-10 PERCENT. AS A
COLD FRONT MOVES THROUGH PORTIONS OF ERN NM/TX PANHANDLE THIS
EVENING...WINDS WILL RAPIDLY SHIFT TO THE NORTH. DESPITE COOLER
TEMPERATURES BEHIND THE FRONT...CRITICALLY LOW RH READINGS ARE
EXPECTED TO CONTINUE THROUGH AT LEAST MIDNIGHT OVER MOST OF THIS
REGION. SOUTH OF THE FRONT...CRITICAL FIRE WEATHER CONDITIONS ARE
EXPECTED TO CONTINUE OVER MOST OF THE HIGHER ELEVATIONS OF THE
GUADALUPE/SACRAMENTO MTNS THROUGH MUCH OF THE NIGHT AS WINDS REMAIN
SUSTAINED OVER 20 MPH.
...CRITICAL FIRE WEATHER AREA - SURROUNDING THE EXTREMELY CRITICAL
FIRE WEATHER OUTLOOK INCLUDING ERN AZ...MUCH OF NM...FAR SERN
CO/SWRN KS...WEST TX/WRN OK...
PRIMARY CONDITIONS: SUSTAINED WSWLY WINDS FROM 20-30 MPH WITH GUSTS
OVER 40 MPH...MIN RH READINGS FROM 5-15 PERCENT...COLD FRONTAL
PASSAGE
SURROUNDING THE EXTREMELY CRITICAL FIRE WEATHER THREAT...SLIGHTLY
WEAKER SFC WINDS WILL EXIST. BUT WIND SPEEDS WILL REMAIN WELL ABOVE
CRITICAL THRESHOLDS TODAY...AS MODERATE MID LEVEL WINDS/STEEP
LOW-MID LEVEL LAPSE RATES CO-EXIST. THE ERN EDGE OF THE CRITICAL
FIRE WEATHER THREAT WILL EXIST OVER WRN OK/NWRN-WCENTRAL TX IN THE
WAKE OF A DRYLINE PASSAGE. DESPITE COOLER TEMPERATURES IN PORTIONS
OF NRN NM...SERN CO IN THE WAKE OF A STRONG COLD FRONT...VERY LOW RH
READINGS AND STRONG WINDS WILL CONTINUE TO SUPPORT CRITICAL FIRE
WEATHER CONDITIONS FOR AT LEAST 4-6 HRS TODAY. AS THE COLD FRONT
PUSHED SWD THROUGH THE TX SOUTH PLAINS/TX PANHANDLE AND WRN OK LATE
THIS AFTERNOON AND THIS EVENING...WINDS WILL SHIFT RAPIDLY TO THE
NORTHWEST. A LAG IN COOLER TEMPERATURES SHOULD SUPPORT AT LEAST A
FEW HOURS OF CRITICAL FIRE WEATHER CONDITIONS AFTER THE FRONTAL
PASSAGE.
...CRITICAL FIRE WEATHER AREA - NRN/CENTRAL FLA...
PRIMARY CONDITIONS: NELY WINDS AROUND 15 MPH...MIN RH READINGS FROM
25-35 PERCENT
VERY DRY LOW LEVELS /MIN RH READINGS FROM 25-35 PERCENT/ WILL REMAIN
OVER INTERIOR PORTIONS OF NRN/CENTRAL FLA TODAY SUPPORTED BY FLOW
AROUND SFC HIGH PRESSURE OFF THE SERN COAST. A SUFFICIENTLY STRONG
PRESSURE GRADIENT WILL SUPPORT SUSTAINED WINDS AROUND 15 MPH LEADING
TO CRITICAL FIRE WEATHER CONDITIONS.
...SRN APPALACHIANS...
RECENT FREEZING TEMPERATURES HAVE LIKELY CURED SOME FINER FUELS OVER
THE AREA. DESPITE AN INCREASING PRESSURE GRADIENT...MARGINAL WINDS
SPEEDS /SFC WINDS AROUND 15 MPH/ WILL PRECLUDE CRITICAL FIRE WEATHER
CONDITIONS.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0342 AM CDT THU MAY 01 2008
VALID 021200Z - 031200Z
...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE SRN HIGH
PLAINS...
...SYNOPSIS...
A STRONG UPPER TROUGH WILL SLOWLY SHIFT EWD THROUGH THE PLAINS
TOWARDS THE MS VALLEY TOMORROW. IN THE WAKE OF THIS TROUGH AND SOUTH
OF A STRONG COLD FRONT...WLY WINDS WILL REMAIN MODERATE OVER THE SRN
HIGH PLAINS REGION. VERY LOW RH READINGS WILL COMBINE WITH THESE
WINDS TO SUPPORT ANOTHER DAY OF CRITICAL FIRE WEATHER CONDITIONS
OVER THE SRN HIGH PLAINS. DOWNSTREAM OF THIS SYSTEM...UPPER RIDGING
WILL SUPPORT ABOVE NORMAL TEMPERATURES OVER THE SERN/MID-ATLANTIC
STATES. DESPITE INCREASING SFC SLY WINDS...MIN RH READINGS WILL
LIKELY REMAIN ABOVE CRITICAL LEVELS.
...CRITICAL FIRE WEATHER AREA - PORTIONS OF CNTRL/ERN NM..WEST TX...
PRIMARY CONDITIONS: SUSTAINED WLY WINDS FROM 20-25 MPH WITH GUSTS UP
TO 30 MPH...MIN RH READINGS FROM 5-10 PERCENT
IN THE WAKE OF A DEPARTING STRONG SHORTWAVE TROUGH...RESIDUAL
MODERATE MID LEVEL WIND LEVEL WINDS COMBINED WITH STEEP LOW-MID
LEVEL LAPSE RATES WILL SUPPORT ANOTHER DAY OF MODERATE WIND SPEEDS
/ALBEIT MUCH LESS THAN DAY ONE/. SUSTAINED WLY WINDS FROM 20-25 MPH
/STRONGEST JUST EAST OF THE CENTRAL/GUADALUPE MTNS IN ERN NM/ WITH
GUSTS UP TO 30 MPH ARE EXPECTED. DESPITE MUCH COOLER TEMPERATURES...
VERY LOW RH READINGS LESS THAN 10 PERCENT ARE STILL EXPECTED AS
LARGE SCALE SUBSIDENCE WILL SUPPORT SFC DEWPTS BELOW ZERO. WITH LACK
OF LARGER SCALE SUPPORT SFC WINDS ARE EXPECTED TO DIMINISH BELOW
CRITICAL LEVELS AROUND SUNSET.
...TX PANHANDLE/WRN OK...
EAST OF THE CRITICAL AREA AND SOUTH OF A STRONG COLD
FRONT...SLIGHTLY WEAKER LAPSE RATES AND LACK OF A STRONG PRESSURE
GRADIENT ARE EXPECTED TO KEEP SUSTAINED WLY WINDS LESS THAN 20 MPH.
HOWEVER...LOW DEWPTS IN THE SINGLE DIGITS/TEENS WILL PRODUCT RH
READINGS LESS THAN 15 PERCENT...MAINTAINING VERY HIGH FIRE DANGER.
...FLA...
AN INCREASING SLY COMPONENT TO THE LOW LEVEL FLOW SHOULD SUPPORT MIN
RH READINGS ABOVE 35 PERCENT FOR MOST OF THE DAY. COMBINED WITH
MARGINAL WIND SPEEDS OVER INTERIOR PARTS OF THE STATE /WHERE THE
LOWEST RH READINGS ARE EXPECTED/ A CRITICAL FIRE WEATHER THREAT IS
NOT EXPECTED.
