.DISCUSSION...
THE BACKSIDE OF THE UPPER TROUGH EJECTS EASTWARD TODAY. THIS WILL ALLOW WARM AND
DRY CONDITIONS TO RETURN TO THE FIRE AREA THROUGH AT LEAST MONDAY. A VERY WEAK
UPPER LOW IS EXPECTED TO DRIFT INTO THE PACIFIC NORTHWEST ON MONDAY WHICH MAY HELP
BRING A SLIGHT CHANCE OF THUNDERSTORMS BACK IN THE FORECAST. OTHERWISE A SURFACE
HIGH ACROSS WESTERN MONTANA AND A SURFACE THERMAL TROUGH ACROSS OREGON MAY BRING
A SLIGHT ENHANCEMENT TO THE UP DRAINAGE FLOW DURING THE DAYTIME TODAY AND SUNDAY.
