DAY 3-8 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0207 PM CST SUN DEC 04 2016

VALID 061200Z - 121200Z

AN ACTIVE SYNOPTIC PATTERN WILL REMAIN IN PLACE ACROSS THE LOWER 48
THROUGH THE EXTENDED FORECAST PERIOD...WITH COOL AND UNSETTLED
CONDITIONS RESULTING IN A LOW FIRE WEATHER THREAT.  BROADLY CYCLONIC
FLOW ALOFT WILL ENCOMPASS MUCH OF THE U.S. AT THE START OF THE
FORECAST PERIOD...WITH SHORTWAVE TROUGHS OVER THE LOWER MISSISSIPPI
VALLEY...NEAR LAKE SUPERIOR...AND IN THE NORTHERN ROCKIES.  THE
CYCLONIC FLOW PATTERN WILL SHIFT SLOWLY EASTWARD THROUGH D5/THU...
WHILE BEING REINFORCED UPSTREAM BY ANOTHER DISTURBANCE THAT WILL
MOVE TOWARD THE PACIFIC NORTHWEST.  AT THE SURFACE...A STRONG HIGH
PRESSURE AREA WILL BUILD INTO THE GREAT PLAINS BEHIND A STRONG...
SOUTHEASTWARD-MOVING COLD FRONT.  THIS HIGH WILL CONTINUE TO BUILD
SOUTHWARD INTO AREAS OF THE INTERMOUNTAIN WEST AND DEEP SOUTH...
RESULTING IN A SEASONABLY COOL AIRMASS AND LOW FIRE WEATHER THREAT
IN MUCH OF THE COUNTRY THROUGHOUT THE EXTENDED PERIOD.  MODELS
INDICATE THAT A WEAK OFFSHORE FLOW PATTERN WILL EXIST ACROSS
PORTIONS OF SOUTHERN CALIFORNIA ON D4/WED...ALTHOUGH COOL SURFACE
TEMPERATURES AND RELATIVELY HIGH RH SHOULD KEEP ANY FIRE WEATHER
THREAT ON THE LOW END IN THAT AREA.
