.DISCUSSION...

HIGH PRESSURE OVER CENTRAL AND WESTERN WYOMING WILL RESULT IN A
FAIRLY BENIGN DAY OVER THE FIRE. DAYTIME HUMIDITY WILL DECREASE
COMPARED TO WHAT WAS EXPERIENCED ON THE FIRE THURSDAY...BUT WILL
NOT REACH INTO THE TEENS. ADDITIONALLY...THE HIGH PRESSURE WILL
KEEP GENERALLY LIGHT WIND OVER THE FIRE TODAY...THOUGH SOME GUSTS
TO AROUND 15 MPH MAY BE POSSIBLE. IT IS NOT CURRENTLY ANTICIPATED
THAT ANY STORM ACTIVITY WILL DIRECTLY IMPACT THE FIRE...THOUGH
ISOLATED THUNDERSTORMS MAY PASS NEARBY. IT IS POSSIBLE THAT THESE
STORMS MAY PRODUCE SOME GUSTY OUTFLOWS WHICH MAY IMPACT THE AREA
THIS AFTERNOON...THOUGH CONFIDENCE IN STORM DEVELOPMENT IS NOT
HIGH. TOMORROW WILL BE DIFFERENT AS A STRONGER SOUTHWEST FLOW
DEVELOPS. GUSTY CONDITIONS WILL BE POSSIBLE IN THE AFTERNOON...BUT
DAYTIME HUMIDITY WILL INCREASE WITH ANOTHER PUSH OF MOISTURE. THIS
PUSH OF MOISTURE MAY AGAIN PRODUCE SOME NEARBY THUNDERSTORM
ACTIVITY WITH CONSEQUENT PERIODS OF GUSTY WIND.

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