Forecast is based on ignition time of 1000 CDT on May 08.

Service.

.DISCUSSION...Winds are forecast to become easterly by Wednesday
morning, then eventually northeast by later afternoon or evening.
We are expecting scattered showers/thundershowers across the
region by afternoon, but very difficult to pinpoint if the burn
site will directly be affected by a shower, as they will be
scattered in nature. That said, it does appear the best chances
will hold off until the afternoon hours.
