.DISCUSSION...
LATEST H2O SATIMG SHOWING NEXT PAC WAVE PUSHING ACROSS BC WITH 140KT 
300MB JET NOSING INTO VC ISLAND.  MODELS TRENDING FURTHER NORTH THAN 
PREVIOUS 12Z RUN WITH WAVE SLICING ESE INTO NRN MONTANA TONIGHT.  
INCREASING 700MB FLOW ALONG WITH APPROACHING SURFACE FRONT AND 
STRONG FLOW ALOFT EXPECTED TO GENERATE ADVISORY LEVEL WINDS STARTING 
LATE TONIGHT AND CONTINUING THROUGH A GOOD PORTION OF THE DAY 
SATURDAY. HENCE HAVE ISSUED A WIND ADVISORY FOR VALLEY ZONES.  
OVERNIGHT LOWS LIKELY TO FALL BEFORE MIDNIGHT TONIGHT AND HAVE 
ADJUSTED GRIDS TO REFLECT THIS.  BROAD FLAT UPPER RIDGE GRADUALLY 
BUILDS OVER PAC NW SUNDAY THROUGH MONDAY WITH CORRESPONDING DECREASE 
IN PRECIPITATION POTENTIAL AND INCREASE IN DAY TIME TEMPERATURES 
THROUGH THE PERIOD. HUSTON 

IN THE EXTENDED FOR MONDAY NGT THROUGH FRIDAY NGT...MODEL RUNS FOR 
EXTENDED SUITES ARE MUCH DRIER THAN PREVIOUS DAY.  MAIN FEATURE OF 
THE PERIOD IS LOW AMPLITUDE U/L RIDGING OVER THE WRN US WITH THE 
STORM TRACK STAYING NEAR THE US-CAN BORDER.  THIS DOES ALLOW FOR 
SOME OCCASIONAL CLOUDINESS WITH SLIGHT CHC OF PRECIP ALONG THE 
CONTDIVID AND EXTRM NRN ZONES.  THE ONE LONE EXCEPTION IS THE 
STRONGEST S/W OF THE PERIOD WHICH MOVES THROUGH SERN ID DURING THE 
DAY WED.  HOWEVER EURO/UK PRODUCTS DO NOT HAVE THIS S/W AS INTENSE 
AS THE GFSX...SO THIS FEATURE MAY BE OVERDONE.  BY FRI/FRI 
NGT...GFSX MOS GUIDANCE BRINGS BACK SLT CHC/LOW CHC POPS FOR THE 
AREA.  PATTERN DOES NOT SUPPORT THIS WITH LARGE LOW IN ERN PAC AND 
ANOTHER IN THE CENTRAL GREAT PLAINS...CAN ONLY ASSUME CLIMATOLOGY 
INFLUENCE IN EQUATIONS HAS OVERPOWERED THE SYNOPTIC SITUATION.  WILL 
LOWER ZERO FOR MOST LOCATIONS EXCEPT ALONG NRN BORDER WHERE SLT CHC 
MAY RULE WITH WEAK ZONAL FLOW AND POSSIBLE UPSLOPE SHOWERS IN 
FAVORABLE TERRAIN.  MESSICK
