DAY 3-8 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0328 PM CST SUN DEC 28 2014

VALID 301200Z - 051200Z

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

A SHORTWAVE TROUGH OVER THE WRN STATES AT THE BEGINNING OF THE
PERIOD ON D3/TUE WILL MOVE SWD AND CLOSE OFF OVER THE SWRN U.S. BY
D4/WED. A BROAD AREA OF SFC LOW PRESSURE WILL DEVELOP OVER SRN
CA/WRN AZ IN ASSOCIATION WITH THE UPPER LOW...AND SLY WINDS WILL
ADVECT A SOMEWHAT WARMER AND DRIER LOW LEVEL AIR MASS INTO PORTIONS
OF SRN AZ TUE AFTERNOON. MARGINAL FORECAST WIND SPEEDS AND
RELATIVELY MOIST FUELS DUE TO RAINFALL ACROSS SRN AZ OVER THE PAST
TWO WEEKS SHOULD LIMIT THE CRITICAL FIRE WEATHER THREAT...AND NO
PROBABILITIES HAVE BEEN ADDED FOR D3/TUE.

THE CLOSED UPPER LOW WILL SLOWLY MOVE EWD TOWARDS THE CNTRL PLAINS
FROM D4/WED TO D7/SAT. SFC HIGH PRESSURE THAT WILL ALREADY BE IN
PLACE ON D3/TUE ACROSS A BROAD MAJORITY OF THE CONUS E OF THE
ROCKIES WILL KEEP TEMPERATURES GENERALLY COLD FROM D4/WED TO D6/FRI.
SFC CYCLOGENESIS TO THE LEE OF THE ROCKIES WILL PROBABLY OCCUR AS
THE UPPER LOW MENTIONED ABOVE OPENS INTO A TROUGH AND EJECTS EWD
ACROSS THE CNTRL PLAINS TO THE OHIO VALLEY VICINITY BY SOMETIME NEXT
WEEKEND. PRECIPITATION ASSOCIATED WITH THE SFC LOW AND UPPER TROUGH
ALONG WITH A COLD SFC HIGH MOVING SWD ACROSS THE PLAINS ONCE AGAIN
AROUND D8/SUN SHOULD KEEP CRITICAL FIRE WEATHER CONCERNS TO A
MINIMUM.
