DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0204 AM CST SUN FEB 08 2009
VALID 081200Z - 091200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
EARLY MORNING SATELLITE IMAGERY SHOWS A DEEP UPPER TROUGH OVER THE
WRN STATES AND A CLOSED LOW SITUATED OFF THE COAST OF SRN CA. THIS
SYSTEM WILL EJECT EWD DURING THE DAY AND LEAD TO STRENGTHENING FLOW
FIELDS ALOFT /70KT AT 500MB FLOW/ OVERSPREADING THE SRN ROCKIES AND
SRN HIGH PLAINS REGIONS. THIS SYSTEM WILL INDUCE LEE SIDE TROUGHING
OVER THE SRN HIGH PLAINS LEADING TO A STRENGTHENING PRESSURE
GRADIENT ACROSS THE CENTRAL STATES AND A PACIFIC COLD FRONT
WILL MOVE EWD ACROSS NM/FAR WRN TX BY THE EVENING HOURS. AHEAD OF
THIS FEATURE...A RELATIVELY MOIST AIRMASS WILL ADVECT NWWD INTO
PARTS OF THE SRN HIGH PLAINS. W OF A SHARPENING DRYLINE NEAR THE
PECOS RIVER VALLEY AND AHEAD OF THE COLD FRONT OVER PARTS OF SWRN
TX...STRONG WINDS AND MARGINALLY LOW RH WILL ENHANCE THE FIRE
WEATHER THREAT.
...SWRN TX /BIG BEND AREA/...
INCREASING MID-LEVEL MOISTURE AND LIFT FROM THE APPROACHING SYSTEM
WILL LIKELY INHIBIT STRONG DAYTIME HEATING DUE IN PART TO WIDESPREAD
CLOUD COVER. HOWEVER...LATEST ENSEMBLE OUTPUT CONTINUES TO INDICATE
MODERATELY STRONG SUSTAINED SWLY WINDS /20 MPH/ WITH HIGHER GUSTS.
FORECAST SOUNDINGS INDICATE THAT MARGINALLY LOW RH VALUES /LOWER
20S/ MAY OCCUR. BUT WITH MAX TEMPS ONLY WARMING INTO THE
60S...POTENTIAL FOR CRITICALLY LOW RH /15 PERCENT/ APPEARS LOW
ATTM--PRECLUDING A CRITICAL AREA.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0341 AM CST SUN FEB 08 2009
VALID 091200Z - 101200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
AN UPPER TROUGH LOCATED OVER THE CENTRAL PLAINS WILL RAPIDLY MOVE
NEWD TOWARDS THE UPPER MIDWEST AS ANOTHER POTENT TROUGH DIGS SEWD
OVER THE W COAST INTO THE DESERT SW. IN BETWEEN THE TWO
SYSTEMS...UPPER SHORTWAVE RIDGING WILL OCCUR OVER THE S-CENTRAL HIGH
PLAINS STATES. A BELT OF SEASONABLY STRONG FLOW FIELDS WILL EXTEND
FROM THE OHIO VALLEY SWWD TO THE SWRN U.S. AT THE SURFACE...A
CYCLONE WILL MOVE NEWD TOWARDS THE UPPER MIDWEST WITH A TRAILING
PRESSURE TROUGH EXTENDING TOWARDS THE SRN HIGH PLAINS. AT LEAST
BORDERLINE CRITICAL CONDITIONS APPEAR PROBABLE OVER PARTS OF THE
S-CENTRAL HIGH PLAINS DUE TO STRONG WINDS AND MARGINALLY LOW RH.
...S-CENTRAL HIGH PLAINS...
STRONG WSWLY DOWNSLOPING WINDS AND SUFFICIENT SURFACE HEATING WILL
PROMOTE BOUNDARY LAYER MIXING IN THE WAKE OF THE DEPARTING SYSTEM.
MODIFIED FORECAST SOUNDINGS FOR EXPECTED MAX TEMPS INDICATE RH MAY
FALL AS LOW AS THE UPPER TEENS IN AREAS...WITH VALUES 20-25 MORE
WIDESPREAD. SUSTAINED WINDS IN EXCESS OF 25 MPH ARE LIKELY WITH
GUSTS APPROACHING 50 MPH IN AREAS. MAIN COMPLICATING FACTOR APPEARS
TO UNCERTAINTY CENTERED ON FUEL RESPONSE DUE TO D1 PRECIPITATION
AMOUNTS. AS A RESULT...NEXT UPDATE WILL RE-EVALUATE THE POTENTIAL
FOR A CRITICAL AREA OVER A SIZABLE PORTION OF THE S-CENTRAL HIGH
PLAINS.
