DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0158 PM CDT SUN AUG 28 2016

VALID 291200Z - 301200Z

NO CHANGES HAVE BEEN MADE TO THE ELEVATED AREA ACROSS PORTIONS OF
THE NWRN GREAT BASIN AND INTERIOR PACIFIC NORTHWEST. FORECAST
SUSTAINED WINDS OF LESS THAN 20 MPH CONTINUE TO PRECLUDE A CRITICAL
DESIGNATION. SEE THE PREVIOUS DISCUSSION BELOW FOR MORE INFORMATION.

LOCALLY ELEVATED FIRE WEATHER CONDITIONS MAY BE REALIZED BEGINNING
MON AFTERNOON AND CONTINUING THROUGH EARLY TUE MORNING ACROSS PARTS
OF SANTA BARBARA COUNTY IN SRN CA IN ASSOCIATION WITH GUSTY
SUNDOWNER WINDS AND POOR OVERNIGHT RH RECOVERY. THE LIMITED SPATIAL
EXTENT OF THE THREAT PRECLUDES AN ELEVATED AREA AT THIS TIME.

.PREV DISCUSSION... /ISSUED 0340 AM CDT SUN AUG 28 2016/

...SYNOPSIS...
IN THE MID LEVELS...A WAVY BAND OF ENHANCED FLOW WILL PERSIST ACROSS
PORTIONS OF THE NRN CONUS AND ADJACENT SRN CANADA. A SHORTWAVE
TROUGH EMBEDDED WITHIN THIS FLOW EXTENDING OFF THE PACIFIC COAST
WILL APPROACH THE PACIFIC NW BY LATE IN THE PERIOD. A CORRESPONDING
INCREASE IN SWLY FLOW ALOFT IS ANTICIPATED IN SOME PORTIONS OF THE
NWRN CONUS...SUPPORTING AN ELEVATED FIRE-WEATHER RISK.
ELSEWHERE...THE OVERLAP OF ENHANCED WINDS/LOW RH IS PRESENTLY
UNLIKELY.

...PORTIONS OF CNTRL/SRN/ERN ORE...NERN CA...NRN NV...SWRN ID...
DIURNALLY STRENGTHENED VERTICAL MIXING INTO STRENGTHENING FLOW ALOFT
DURING PEAK HEATING IS FORECAST TO SUPPORT SWLY SFC WINDS AROUND
15-18 MPH WITH LOCALLY HIGHER GUSTS. THE DRY ANTECEDENT AIR MASS
COMBINED WITH AREAS OF DOWNSLOPE-FLOW-ENHANCED WARMING/DRYING IS
EXPECTED TO YIELD MINIMUM RH AROUND 5-12 PERCENT AMIDST AREAS OF DRY
FUELS. AS A RESULT...ELEVATED FIRE-WEATHER CONDITIONS ARE
ANTICIPATED. A MORE PROMINENT INCREASE IN MID-LEVEL WIND SPEEDS IN
SOME AREAS IS EXPECTED TO BE DELAYED UNTIL AFTER SUNSET...WHICH
SHOULD GREATLY MINIMIZE THE RISK FOR CRITICAL CONDITIONS.
