VALID 011200Z - 071200Z

UPPER RIDGING IS EXPECTED TO REMAIN IN PLACE ACROSS MUCH OF THE WRN
CONUS THROUGHOUT THE WEEK WITH PERSISTENT DOWNSTREAM TROUGHING
ACROSS THE CNTRL AND ERN CONUS. THIS BUILDING UPPER RIDGE WILL
RESULT IN TEMPERATURES THAT ARE ABOVE AVERAGE FOR MUCH OF THE GREAT
BASIN...NRN CA...PACIFIC NW...AND NRN ROCKIES. HIGHS ACROSS THE
PACIFIC NW WILL LIKELY BE 12 TO 20 DEGREES ABOVE NORMAL ON D4/THU
AND D5/FRI WITH RESULTING MIN VALUES BELOW 15 PERCENT FOR MUCH OF
ERN WA/ORE AND ID.

THE UPPER RIDGE WILL BEGIN TO DAMPEN SOMEWHAT ON D5/FRI OR D6/SAT AS
THE SRN PORTION OF A STRONG SHORTWAVE TROUGH DROPPING SEWD ACROSS
NRN BRITISH COLUMBIA AND INTO CNTRL ALBERTA IMPINGES ON IT. AS THIS
OCCURS...THERE WILL BE AN INCREASED POTENTIAL FOR TSTM ACTIVITY WITH
ANY SUBTLE SHORTWAVES THAT MOVE THROUGH THE REGION. HOWEVER...THERE
ARE NOT CURRENTLY ANY CONSISTENT SIGNALS WITHIN THE GUIDANCE
REGARDING THE BEST DAY FOR TSTM ACTIVITY WITHIN THE EXTENDED
PERIOD...PRECLUDING THE DELINEATION OF ANY THREAT AREAS WILL THIS
FORECAST.

THE WEAK SURFACE PRESSURE GRADIENT AND LACK OF STRONG MID TO UPPER
LEVEL FLOW ACROSS THE MAJORITY OF THE CONUS WILL KEEP THE
LARGE-SCALE WIND-DRIVEN FIRE WEATHER THREAT LOW THROUGHOUT THE
PERIOD.
