.DISCUSSION...

SOME FOG OR LOW CLOUDS WILL BE POSSIBLE THIS MORNING DUE TO THE
PRECIPITATION OVER THE FIRE AREA YESTERDAY. OTHERWISE...A RIDGE OF
HIGH PRESSURE WILL BEGIN TO BUILD INTO THE REGION TODAY AND REMAIN
IN PLACE FOR SATURDAY. THIS WILL RESULT IN DRY CONDITIONS AND
MAINLY LIGHT AND TERRAIN DRIVEN WINDS. THE TREND OVER THE NEXT
COUPLE OF DAYS WILL BE WARMER TEMPERATURES AND LOWER HUMIDITY.

A WEAK SYSTEM PUSHING ACROSS THE NORTHERN INTERMOUNTAIN WEST ON
SUNDAY WILL RESULT IN MODEST WESTERLY WINDS DEVELOPING...AND
COULD RESULT IN VERY ISOLATED SHOWERS OR THUNDERSTORMS IN THE
AFTERNOON AND EVENING. WINDIER CONDITIONS ARE EXPECTED MONDAY
WITH A BETTER CHANCE FOR SOME SHOWERS AND THUNDERSTORMS.

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