...REMARKS...
Please report all forecast elements in 1-hr increments for today,

OUR MAIN CONCERN: possible impact
of smoke and/or fog on I-10, which
is just north of the burn unit.

NWS New Orleans products consulted:

1. PointAndClick Forecasts for CPT G-15N 30.44N 88.67W , issued at
10:18am and 1:17pm Thursday, and at 4:17am Friday.

2. Point Forecast Matrices for Pascagoula MS, issued 404am Thursday
and 418am Friday.

4. Verification of Spot Forecast CPT G-15N, issued 1546hrs Thursday.

QUESTIONS

1. Wind speed in the PointAndClick Forecast is unusually high Friday
night.  Normally we would expect to see wind speed in the 2-4mph
range at night, when we are under high pressure.  According to
yesterday afternoons Spot Forecast for CPT G-15N, a reinforcing
impulse will maintain wind speed at 5mph Friday night.  What is the
current thinking on this question  In a related question, we would
like to know what will be the main factor influencing movement of
smoke Friday nightgradient flow, drainage flow, or some other factor

2. This mornings 4:17am PointAndClick Forecast shows much higher
Dewpoint and RH for today, than was forecasted in yesterday
afternoons Spot Forecast.  Yesterday RH was significantly lower than
forecasted at KPQL.  There is mention of a reinforcement of the cool
air mass in todays Area Forecast Discussion.  All of these factors
indicate that todays RH could be much lower than expected.  Please
explain how these factors are considered in your forecast.

3. Please explain what happened to cause such large errors in
temperature, dewpoint and RH in yesterday afternoons Spot Forecast
for CPT G-15N.  Also why dewpoints were consistently higher at SHCM6
than at KPQL.  What effect will this have on todays forecast

4. Please include a Fog Potential Statement for Friday night/Saturday
morning, and for Saturday night/Sunday morning.
