DAY 3-8 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0304 PM CST SAT DEC 27 2014

VALID 291200Z - 041200Z

NO LARGE SCALE FIRE WEATHER AREAS ARE EXPECTED THROUGH THE EXTENDED
FORECAST PERIOD.

THE UPPER PATTERN WILL BEGIN WITH A BROAD UPPER TROUGH OVER THE
CNTRL AND WRN STATES WITH SEVERAL DISTURBANCES ROTATING AROUND THE
MEAN UPPER TROUGH THROUGH D4/TUE. BY D5/WED...ONE SUCH SHORTWAVE
TROUGH IS FORECAST TO CLOSE OFF OVER THE WRN STATES...AND THEN
SLOWLY ADVANCE EWD TOWARDS THE CNTRL PLAINS BY D7/FRI. AN UPPER
RIDGE SHOULD REMAIN OFF THE WEST COAST THROUGH THE FORECAST PERIOD.

BY D4/TUE INTO D5/WED...MODELS SUGGEST THAT A GREAT BASIN SFC HIGH
WILL STRENGTHEN ONCE AGAIN. COMBINED WITH A FAVORABLE PRESSURE
GRADIENT...WEAK TO MODERATE OFFSHORE WINDS APPEAR LIKELY FOR
PORTIONS OF SRN CA FROM LATE D4/TUE INTO D5/WED. HOWEVER...
TEMPERATURES WILL REMAIN COOL AND RECENT RAINFALL HAS RESULTED IN
GENERALLY MOIST FUELS FOR SRN CA...WHICH COMBINED WITH ADDITIONAL
FORECAST RAINFALL SHOULD MITIGATE ANY CRITICAL FIRE WEATHER THREAT.
GUSTY SLY WINDS MAY ALSO OCCUR IN CONJUNCTION WITH SOMEWHAT MILD
TEMPERATURES FOR PORTIONS OF SERN AZ ALONG A SFC TROUGH DURING THE
AFTERNOON ON D4/TUE...BUT RECENT PRECIPITATION AND MARGINAL RH
VALUES SHOULD MITIGATE ANY CRITICAL FIRE WEATHER THREAT.

E OF THE ROCKIES...PERIODIC SURGES OF SFC HIGH PRESSURE WILL MOVE
ACROSS THE CONUS...KEEPING TEMPERATURES COLD AND MINIMIZING ANY FIRE
WEATHER THREAT.
