.DISCUSSION...
Showers and thunderstorms will remain mostly south of the fire
today and through the weekend. Cannot rule out gusty outflows
reaching the fire perimeter as a result of nearby storm activity.
Otherwise, look for light, terrain driven winds through each
period. High pressure moving in will increase temperatures each
day through the weekend. Looking ahead, afternoon thunderstorm
chances increase to 20-30% by Monday and Tuesday.
