OF HIGH RELATIVE HUMIDITY AND CHANCES FOR PRECIPITATION. WIDELY
SCATTERED SHOWERS ARE POSSIBLE TODAY...MAINLY THIS AFTERNOON. SHOWERS
ARE EXPECTED TO INCREASE IN COVERAGE THIS EVENING...WITH SCATTERED
TO LOCALLY NUMEROUS SHOWERS TONIGHT AND FRIDAY OVER WESTERN
WYOMING. ENOUGH COLD AIR WILL MOVE INTO THE AREA WITH SNOW LEVELS
DROPPING DOWN TO AROUND 8000 FEET LATE TONIGHT INTO FRIDAY.

THIS SLOW MOVING STORM SYSTEM WILL FINALLY EXIT LATE FRIDAY/FRIDAY
NIGHT...WITH DRY AND WARMER CONDITIONS EXPECTED SATURDAY AND SUNDAY.

ANOTHER STORM SYSTEM...BUT MUCH MORE PROGRESSIVE...WILL AFFECT

SOME PRECIPITATION.
