NWS STORM PREDICTION CENTER NORMAN OK
1003 AM CST THU NOV 27 2014

VALID 271700Z - 281200Z

...NO CRITICAL AREAS...

NO CHANGES TO PREVIOUS FORECAST. BEST POTENTIAL FOR LOCALLY ELEVATED
CONDITIONS ACROSS THE SERN CONUS WILL EXIST IN SRN FL...PRIMARILY SE
OF LAKE OKEECHOBEE. HIGH TEMPERATURES SHOULD BE IN THE LOWER-MID
70S...WHICH COMBINED WITH THE DRY POST-FRONTAL AIR MASS...WILL
RESULT IN RH VALUES NEAR 30-35 PERCENT. WHILE MOST OF FL HAS
EXPERIENCED CONSIDERABLE WETTING RAINS RECENTLY...THIS PORTION OF FL
HAS GENERALLY EXPERIENCED BELOW-NORMAL RAINFALL OVER THE LAST 7-14
DAYS. HOWEVER...ONLY LOCALIZED ELEVATED CONDITIONS ARE FORECAST...AS
THE COMBINATION OF LOW RH AND MARGINAL SUSTAINED WIND VALUES SHOULD
BE BRIEF/SPOTTY. AS SUCH...NO DELINEATION WILL BE INTRODUCED.

...SYNOPSIS...
UPPER LEVEL PATTERN WILL TREND MORE ZONAL AS A SHORTWAVE TROUGH
MOVES THROUGH THE NORTHEAST STATES AND WRN CONUS RIDGING
DEAMPLIFIES. AT THE SURFACE...HIGH PRESSURE WILL TRANSLATE SEWD
ACROSS THE MS VALLEY AND INTO THE TN VALLEY/SOUTHEAST STATES WHILE
LEE TROUGHING EXPANDS OVER THE HIGH PLAINS.

TEMPERATURES IN THE LOW 80S AND RH VALUES BELOW 15 PERCENT WILL
RESULT IN SOME LOCALLY ELEVATED FIRE WEATHER CONDITIONS ACROSS SRN
CA BUT WEAK WINDS WILL TEMPER A GREATER THREAT. SOME LOCALLY
ELEVATED CONDITIONS ARE ALSO EXPECTED ACROSS SRN AL/GA AND FL AS A
POST-FRONTAL REGIME USHERS IN A VERY DRY AIRMASS -- PW VALUES AROUND
0.20 INCH...WHICH IS AROUND THE 10TH PERCENTILE -- AND WINDS
APPROACH 15 MPH.

...SRN HIGH PLAINS...
HIGH PLAINS LEE TROUGHING WILL INCREASE THE SURFACE PRESSURE
GRADIENT ENOUGH TO SUPPORT SUSTAINED SWLY WINDS AROUND 15 TO 20 MPH
THROUGHOUT THE SRN HIGH PLAINS. TEMPERATURES WILL CLIMB INTO THE MID
60S WITH MIN RH VALUES LIKELY FROM 15 TO 20 PERCENT. GENERALLY
MARGINAL CONDITIONS COMBINED WITH MOIST FUELS WILL MITIGATE MUCH OF
THE FIRE WEATHER THREAT ALTHOUGH SOME LOCALLY ELEVATED CONDITIONS
ARE POSSIBLE.
