DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0157 AM CST SAT FEB 13 2016

VALID 141200Z - 151200Z

...SYNOPSIS...
AS A MID-LEVEL WIND-SPEED MAXIMUM EXTENDS SEWD FROM PARTS OF THE NRN
GREAT BASIN TO THE SRN GREAT PLAINS...BROADLY CYCLONIC MID-LEVEL
FLOW WILL AMPLIFY ACROSS PORTIONS OF THE CNTRL/ERN CONUS. THIS WILL
OCCUR AS A HIGH-AMPLITUDE RIDGE OVER THE E PACIFIC CONTINUES
ADVANCING TOWARD THE WRN CONUS. SUBSIDENCE DOWNSTREAM OF THE RIDGE
WILL ENCOURAGE A STRENGTHENING SFC ANTICYCLONE ACROSS PARTS OF THE
CNTRL GREAT BASIN.

...SRN CA COASTAL RANGES/ADJACENT FOOTHILLS AND VICINITY...
THE SFC PRESSURE GRADIENT ACROSS PARTS OF SRN CA WILL GRADUALLY
TIGHTEN THROUGH THE PERIOD...TO THE SW OF THE AFOREMENTIONED
STRENGTHENING SFC ANTICYCLONE. THIS WILL RESULT IN AN INCREASE IN
NELY TO ENELY SFC WINDS. A MORE PROMINENT INCREASE IN THESE WINDS IS
EXPECTED TO OCCUR SUNDAY NIGHT.

ON SUNDAY...NELY TO ENELY SFC WINDS AROUND 15-20 MPH ARE EXPECTED TO
COMBINE WITH MINIMUM RH FROM THE UPPER SINGLE DIGITS TO THE MIDDLE
TEENS AS TEMPERATURES RISE TO ABOVE-NORMAL READINGS -- I.E. IN THE
70S AND 80S. THIS WILL RESULT IN ELEVATED FIRE-WEATHER CONDITIONS
GIVEN AREAS OF DRY FUELS. BORDERLINE-CRITICAL FIRE-WEATHER
CONDITIONS WILL BE POSSIBLE ON A BRIEF/SPOTTY BASIS.

THEN FOR SUNDAY NIGHT...NELY TO ENELY WINDS WILL STRENGTHEN IN MANY
AREAS...WITH SPEEDS AROUND 20-30 MPH POSSIBLE IN SOME AREAS --
STRONGEST THROUGH FAVORED PASSES AND CANYONS. ELEVATED FIRE-WEATHER
CONDITIONS WILL LIKELY CONTINUE INTO THE OVERNIGHT HOURS.
HOWEVER...NOCTURNAL COOLING WILL TEND TO SUPPORT SUFFICIENT RH
RECOVERY -- ALBEIT MODEST AS RH VALUES HOLD IN THE 20S AND 30S IN
SOME AREAS -- TO LIMIT THE CRITICAL FIRE-WEATHER POTENTIAL.

OVERALL...PROSPECTS FOR STRONG WINDS TO OVERLAP WITH LOW RH ON ANY
MORE THAN A BRIEF BASIS ARE CURRENTLY LIMITED...PRECLUDING CRITICAL
DESIGNATION AT THIS TIME. HOWEVER...ELEVATED TO BORDERLINE-CRITICAL
FIRE-WEATHER CONDITIONS WILL BE LIKELY THROUGH THE PERIOD.
