DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0119 AM CST MON FEB 13 2012
VALID 131200Z - 141200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
A SFC ANTICYCLONE ACROSS THE CNTRL/ERN CONUS WILL SHIFT EWD AND MOVE
OVER PARTS OF THE WRN NORTH ATLANTIC. THE DRY AIR MASS ASSOCIATED
WITH THIS ANTICYCLONE -- PW VALUES AOB 0.20 INCH AT MANY LOCATIONS
PER GPS DATA AND SUNDAY EVENING OBSERVED SOUNDINGS -- IS FORECAST TO
SUPPORT LOW RH READINGS ACROSS PARTS OF THE SERN CONUS.
HOWEVER...THE COMBINATION OF LIGHT WINDS AND AREAS WHERE PRECIP HAS
RECENTLY FALLEN WILL MITIGATE THE FIRE WEATHER THREAT IN THESE
LOCATIONS. MEANWHILE...A MID/UPPER-LEVEL SHORTWAVE TROUGH WILL MOVE
FROM THE CNTRL/SRN PLAINS EWD TOWARD THE OH/TN VALLEY REGION WHILE
DEAMPLIFYING. A BROAD AREA OF PRECIP WILL MOVE EWD ACROSS PARTS OF
THE PLAINS AND MS VALLEY REGION IN ASSOCIATION WITH THE SHORTWAVE
TROUGH AND ATTENDANT SFC LOW AND FRONTS. TO THE W OF THIS SHORTWAVE
TROUGH...ANOTHER SHORTWAVE TROUGH AND ITS ATTENDANT CLOSED LOW OVER
THE WEST COAST WILL MOVE SSEWD OVER PARTS OF CA/NV AND EVENTUALLY
APPROACH THE LOWER CO RIVER VALLEY. A ZONE OF MODERATE FLOW IN THE
MID LEVELS TO THE SOUTH OF THE SHORTWAVE TROUGHS WILL COVER THE SRN
STATES.
...SWRN TX/SERN NM...
THE PREVIOUSLY MENTIONED ZONE OF MODERATE FLOW IN THE MID LEVELS IS
FORECAST TO SUPPORT DOWNSLOPE WLY WINDS...WITH SUSTAINED SFC WIND
SPEEDS OF 15 TO 25 MPH AND HIGHER GUSTS. DESPITE THE CONTRIBUTION OF
DOWNSLOPE EFFECTS TO WARMING/DRYING THE BOUNDARY LAYER...MINIMUM RH
VALUES ARE GENERALLY EXPECTED TO BE IN THE 20S TO THE LOWER 30S --
I.E. ABOVE CRITICAL THRESHOLDS. THIS IS DUE TO THE ABSENCE OF A
DRIER AIR MASS AND THE ABSENCE OF EVEN WARMER SFC TEMPERATURES
/MAXIMUM TEMPERATURES GENERALLY EXPECTED TO BE IN THE 60S/. AS
SUCH...CRITICAL FIRE WEATHER CONDITIONS ARE NOT EXPECTED.
FURTHERMORE...THE OCCURRENCE OF RECENT PRECIPITATION IN MANY AREAS
WILL REDUCE THE FIRE WEATHER THREAT.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0120 AM CST MON FEB 13 2012
VALID 141200Z - 151200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
A MID/UPPER-LEVEL SHORTWAVE TROUGH AND EMBEDDED CLOSED LOW WILL MOVE
FROM THE LOWER CO RIVER VALLEY TOWARD NM. A MID/UPPER-LEVEL JET
STREAM...DRAPED ACROSS THE SRN STATES...WILL BE LOCALLY ENHANCED IN
THE VICINITY OF THE LOW AND SHORTWAVE TROUGH ACROSS PARTS OF SRN
AZ...SRN/ERN NM...AND WRN TX. THE WLY COMPONENT OF THE FLOW ACROSS
THE CNTRL/SRN ROCKIES WILL PROMOTE THE DEVELOPMENT OF A LEE SFC
TROUGH/LOW OVER PARTS OF THE CNTRL/SRN HIGH PLAINS.
...ERN NM...WRN TX...
THE ENHANCED MID-LEVEL FLOW COMBINED WITH THE SFC PRESSURE GRADIENT
IN ASSOCIATION WITH THE AFOREMENTIONED LEE SFC TROUGH/LOW WILL
SUPPORT SSWLY TO SWLY WINDS OF 10 TO 20 MPH AND LOCALLY HIGHER
GUSTS. DESPITE LOCALIZED DOWNSLOPE EFFECTS ACTING TO WARM/DRY THE
BOUNDARY LAYER...MINIMUM RH VALUES ARE GENERALLY EXPECTED TO BE IN
THE 20S TO THE LOWER 30S -- I.E. ABOVE CRITICAL THRESHOLDS. THIS IS
ATTRIBUTABLE TO THE ABSENCE OF A DRIER AIR MASS AND THE ABSENCE OF
EVEN WARMER SFC TEMPERATURES /MAXIMUM TEMPERATURES GENERALLY
EXPECTED TO BE IN THE 60S AND THE LOWER 70S/. AS SUCH...CRITICAL
FIRE WEATHER CONDITIONS ARE NOT EXPECTED. FURTHERMORE...THE
OCCURRENCE OF RECENT PRECIPITATION IN MANY AREAS WILL MITIGATE THE
FIRE WEATHER THREAT.
