.DISCUSSION...

THE STORM RESPONSIBLE FOR THE COOLER AND INCLEMENT WEATHER THIS
PAST WEEK WILL FINALLY PUSH EAST TODAY AND TONIGHT. AS THIS SYSTEM
PUSHES EAST ACROSS THE AREA TODAY...IT WILL RESULT IN A DECENT
SHOT AT GETTING MORE PRECIPITATION...HIGH RELATIVE HUMIDITY AND
COOL CONDITIONS. ENOUGH COLD AIR HAS PUSHED INTO THE AREA WITH
SNOW LEVELS AROUND 7500 FT. THE PRECIPITATION IS EXPECTED TO COME
TO AN END TONIGHT.

DRY CONDITIONS AND A WARMING TREND IS EXPECTED THIS WEEKEND.

ANOTHER STORM SYSTEM...BUT MUCH MORE PROGRESSIVE...WILL AFFECT
NORTHWESTERN WYOMING MONDAY AND MONDAY NIGHT...BRINGING ANOTHER
CHANCE FOR SOME PRECIPITATION.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
