Forecast is based on ignition time of 0800 EST on November 17.

Service.

.DISCUSSION...
A very dry air mass will be in place today as high pressure passes
overhead. The key concern today will be the relative humidity as
values reach critically low levels, falling below 20 percent this
afternoon. Winds begin the day out of the northwest, becoming
variable as the high passes through the region, so while it will
be very dry today, the wind speed will not be a concern. The light
and variable winds continue through the overnight hours under
mainly clear skies. Fog is not expected to develop due to the dry
conditions.
