.DISCUSSION...

Light east to southeast winds today. Look for minimum afternoon
humidity values near 50 percent. There will be widely scattered
afternoon thunderstorms across portions of Central and West Central
Louisiana today. If these storms do develop in the vicinity of the
wildfire, they will produce outflow boundaries with much stronger
wind gusts but it is impossible to determine just where these
outflow boundaries will occur and the direction they would be coming
from until it`s determined just where the storms are in relation to
the wildfire. Mixing heights should increase a little quicker today
compared to Saturday and should level off near 6kft by early to middle
afternoon. Rain chances increase for Monday and again on Tuesday.
