.DISCUSSION...The overall pattern will begin to change for the burn
site as a weak system approaches the area on Tuesday. This will largely
mean cooler temperatures and somewhat higher humidities. The burn
site will largely be sheltered from the afternoon winds, but the burn
site could see winds similar to what is seen during the summer. Rain is
not anticipated in the immediate forecast, but showers and cumulus buildups
may be visible, especially to the southeast. Showers and possibly
a thunderstorm (5-10% chance) will be possible Thursday and Friday.
