DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0313 AM CDT WED APR 01 2009
VALID 011200Z - 021200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SRN NM AND
SW/FAR W TX...
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SRN AND ERN NM...SERN
AZ...AND WRN TX INTO THE BIG BEND AREA...
...SYNOPSIS...
UPPER AIR ANALYSIS AND SATELLITE IMAGERY REVEAL A STRONG S/W TROUGH
MOVING FROM THE PAC NW TOWARDS THE GREAT BASIN. THIS DISTURBANCE IS
ACCOMPANIED BY 500 MB WINDS OF 85 KT...AND 140 KT AT 250 MB. THE
UPPER WAVE IS FORECAST TO MOVE INTO NM BY LATE AFTERNOON...WITH A
40-70 KT MID LEVEL SPEED MAX SPREADING ACROSS SRN NM AND FAR W TX.
MEANWHILE...SURFACE LOW PRESSURE IS FORECAST TO DEEPEN AND SHIFT
SOUTH FROM ERN CO INTO THE TX PANHANDLE. A COLD FRONT WILL MOVE
SOUTH WITH THE LOW...EXTENDING TOWARDS THE W INTO NM/AZ. A WARM AND
VERY DRY AIRMASS WILL DEVELOP DURING THE AFTERNOON SOUTH OF THE
FRONT AS WINDS STRENGTHEN...FAVORING A LARGE AREA OF CRITICAL TO
POSSIBLY EXTREMELY CRITICAL FIRE WEATHER CONDITIONS.
...EXTREMELY CRITICAL FIRE WEATHER AREA - PORTIONS OF SRN NM AND
SW/FAR W TX...
PRIMARY CONDITIONS: VERY STRONG WINDS...LOW RH...MODERATE DROUGHT
A DEEP WELL MIXED BOUNDARY LAYER AIRMASS /EXTENDING UP TO 600 MB/ IS
FORECAST TO DEVELOP ACROSS THE EXTREMELY CRITICAL OUTLOOK AREA BY
MID AFTERNOON. EVENING OBSERVED SOUNDINGS FROM 1/00Z INDICATE A VERY
DRY AIRMASS IS ALREADY IN PLACE ACROSS THE REGION...WITH PWAT VALUES
AOB 0.10 IN...AND SURFACE OBS SHOW DEWPOINTS GENERALLY LESS THAN 10
DEG F. AS THE SURFACE WARMS THROUGH THE AFTERNOON...RH VALUES ARE
FORECAST TO FALL BELOW 10-15 PERCENT. SUSTAINED WINDS WILL RESPOND
TO DEEPENING LOW PRESSURE OVER THE CENTRAL/SRN HIGH PLAINS...EASILY
EXCEEDING 25 MPH. IN ADDITION...AS THE 40-70 KT MID LEVEL JET
SPREADS EAST AROUND THE BASE OF THE UPR LVL TROUGH AND TRAVERSES SRN
NM AND FAR W TX...WIND GUSTS UP TO 50 MPH /POSSIBLY HIGHER/...AS
WELL AS AN ENHANCEMENT TO SUSTAINED WINDS OVER HIGHER TERRAIN WILL
BE POSSIBLE. THESE FACTORS SUGGEST EXTREMELY CRITICAL FIRE WEATHER
CONDITIONS WILL BE POSSIBLE...FAVORING FAST SPREADING FIRES WHICH
COULD SEVERELY HINDER CONTROL EFFORTS.
...CRITICAL FIRE WEATHER AREA - PORTIONS OF SRN AND ERN NM...SERN
AZ...AND WRN TX INTO THE BIG BEND AREA...
PRIMARY CONDITIONS: STRONG WINDS...LOW RH...MODERATE TO SEVERE
DROUGHT
AS LOW PRESSURE DEEPENS...S-SW SURFACE WINDS ARE FORECAST TO
STRENGTHEN OVER WRN INTO N CENTRAL TX. A WEAKNESS IN THE SURFACE
FLOW WILL LIKELY EXIST ALONG A SURFACE TROUGH EXTENDING SWD FROM THE
LOW OVER PORTIONS OF NW INTO SW TX...BUT THEN INCREASE RAPIDLY AGAIN
TO ITS W AND E. A VERY DRY LOW LEVEL AIRMASS WILL BE IN PLACE ACROSS
THE WRN HALF OF TX...WITH RH VALUES FALLING INTO THE SINGLE DIGITS
BY PEAK DAYTIME HEATING. THIS WILL FAVOR CRITICAL FIRE WEATHER
CONDITIONS WITHIN MOST OF THE OUTLOOK AREA OVER W TX...WITH MORE
MARGINAL CONDITIONS POSSIBLE ALONG THE SURFACE TROUGH WHERE A
WEAKNESS IN SUSTAINED WINDS MAY OCCUR.
FARTHER W OVER PORTIONS OF ERN AND SRN NM INTO SERN AZ...FAST MID
LEVEL FLOW WILL OVERSPREAD THE REGION DURING THE AFTERNOON...WHILE
SURFACE WINDS INCREASE IN RESPONSE TO THE LOW OVER THE PLAINS.
SUSTAINED WINDS OF 25 MPH ARE LIKELY...OCCURRING IN CONJUNCTION WITH
RH VALUES IN THE LOWER TEENS...SUPPORTING CRITICAL FIRE WEATHER
CONDITIONS. IN ADDITION...A WIND SHIFT IS LIKELY OVER NM BY EVENING
AS THE COLD FRONT DROPS SOUTH...WHICH COULD POTENTIALLY RESULT IN
ERRATIC FIRE BEHAVIOR.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0318 AM CDT WED APR 01 2009
VALID 021200Z - 031200Z
...CRITICAL FIRE WEATHER AREA FOR S CENTRAL TX...PORTIONS OF SW
TX...AND THE LOW-MID COASTAL PLAIN...
...SYNOPSIS...
A S/W TROUGH WILL MOVE EAST ACROSS THE SRN PLAINS THROUGH THE
MORNING OF THUR/D2...AND REACH THE LWR MS VALLEY REGION BY LATE
AFTERNOON. AS THIS OCCURS...DEEP SURFACE LOW WILL QUICKLY PROGRESS
EWD...CAUSING A SOUTH-SOUTHWESTWARD TRAILING COLD FRONT TO MOVE
ACROSS TX AND INTO THE GULF OF MEXICO. STRONG SUSTAINED WINDS AND
RAPID LOW LVL DRYING WILL OCCUR BEHIND THE FRONT...LEADING TO
CRITICAL FIRE WEATHER CONDITIONS OVER S CENTRAL TX.
...CRITICAL FIRE WEATHER AREA - S CENTRAL TX...PORTIONS OF SW
TX...AND THE LOW-MID COASTAL PLAIN...
PRIMARY CONDITIONS: STRONG WINDS...LOW RH...SEVERE TO EXCEPTIONAL
DROUGHT
A WELL MIXED AIRMASS IS FORECAST TO DEVELOP OVER THE LOWEST 1.5 KM
BY MID TO LATE MORNING BEHIND A DEPARTING COLD FRONT. SUSTAINED
WINDS OF 20-25 MPH...WITH GUSTS UP TO 35 MPH WILL BE POSSIBLE. IN
ADDITION...DRY AIR ADVECTION WITHIN THE POST FRONTAL AIRMASS WILL
SPREAD SOUTH AND EAST ACROSS THE REGION...WITH SURFACE DEWPOINTS
FORECAST TO FALL BELOW 25 DEG F /SLIGHTLY HIGHER VALUES EXPECTED
ALONG COASTAL LOCATIONS/. AS TEMPERATURES WARM THROUGH THE 70S...RH
VALUES WILL DROP BELOW 15-20 PERCENT OVER MOST OF THE OUTLOOK
AREA...FAVORING CRITICAL FIRE WEATHER CONDITIONS...ESPECIALLY WHEN
CONSIDERING THE EXCEPTIONAL DROUGHT PRESENT ACROSS THE REGION.
SURFACE WINDS ARE THEN FORECAST TO DECREASE IN MAGNITUDE THROUGH THE
AFTERNOON...BRINGING CRITICAL CONDITIONS TO AN END.
