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

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
