.TODAY THROUGH TUESDAY NIGHT...
MOST OF THE INTERESTING PART OF FORECAST IN FIRST PERIOD WITH CENTER
OF UPPER LOW HIGHLIGHTED BY LIGHTNING STRIKES AROUND RKS THIS
AFTERNOON.  LOW HAS FINALLY JUMPED THE DIVIDE AND ON THE MOVE.
MAIN BAND OF HEAVIER RAIN THAT TRAVERSED CENTRAL WYOMING THROUGH

EAST ZONES DECREASING WESTWARD THROUGH 04Z WITH ISOLATED POPS IN

CENTRAL OVERNIGHT WITH SATURATED LOWER LAYERS FOR MENTION OF FOG
ALONG RIVER VALLEYS.  COLD AND RAINY START OF LABOR DAY WEEKEND
HAS BEEN A BLESSING TO SOME AND A CURSE TO OTHERS FROM CUSTOMER
FEEDBACK...BUT THE REST OF THIS WEEKEND SHOULD MAKE FOR HAPPY CAMPERS
WITH SUNNY DAYS (WITH THE SMOKE WASHED OUT AND MAYBE EVEN A FEW
WHITE-CAPPED MOUNTAIN PEAKS) AND CLEAR COOL NIGHTS AS DRY
NORTHWEST FLOW PREVAILS. FAR WEST VALLEYS AND MOUNTAINS TO BE WELL
INTO THE 30S THE NEXT FEW NIGHTS. THE NEXT ITEM OF SIGNIFICANCE ON
THE SHORT-TERM HORIZON IS UPPER LOW PROGGED THROUGH CENTRAL CANADA
