.DISCUSSION...

Biggest concern from a fire weather standpoint will be afternoon
relative humidity values again today before some relief with higher
dew point temperatures begins moving into the area. Minimum Relative
humidity values today could drop to 25% for most areas and even lower
for the Mississippi gulf coast to around 20% with a few locations
finding some upper teens.

.Questions...

1. What is the potential, duration, and density for fog tonight
night into the morning? No fog is expected.

2. Is there any potential for sea breeze during the day? or other
changes in wind direction? There isn`t expected to be a sea
breeze, but winds will shift to the south today as the gradient
flow shifts.

3. What is the potential for 20ft winds to increase >16mph and/or
drop below 5 mph and what time frame? 20ft winds will be very
close to or below 5mph for the majority of the day today.

5. Is there a chance that forecasted wind direction or RH could
change more than 12 degrees/percent? Wind could vary more than a
12 degree change at any point during the day.

6. Is there potential for RH to drop below 28% and/or change more
than 12% during the day? RH may drop below 28% this afternoon for
a few hours.
