Forecast is based on ignition time of 1200 CDT on September 21.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...
Initial low cloud cover late this morning will gradually thin
around and just after ignition time resulting in a mostly sunny
to partly cloudy sky. South to south-southeasterly 20-foot winds
around 10 mph this morning will increase slightly during the
afternoon, when some occasional gusts to around 20 mph can be
expected. Copious amounts of Gulf moisture will hold afternoon
relative humidity values around 50 percent. With so much moisture
around, an isolated shower or storm cannot be ruled out mainly
between 3-7 PM, but chances of any activity impacting the burn
site remain quite low today. Slightly drier air will work into the
area on Friday which will limit any precipitation chances, but
otherwise, similar weather to today is anticipated.
