Spot Forecast for Comp 123 Jack Pine...BIA Menominee Tribal
National Weather Service Green Bay WI
950 AM CDT Fri Oct 20 2017

Forecast is based on ignition time of 1000 CDT on October 20.
If conditions become unrepresentative contact the National Weather
Service in Green Bay.

.DISCUSSION...
Southwest flow between high pressure to the east and a frontal
system developing in the Plains will continue to feed unseasonably
mild air into the area today. The winds will bring some added
low-level moisture into the area from the southwest. But plenty
of sunshine will result into mixing into very dry air above the
surface, which will tend to offset the arrival of the moisture and
drive humidities down again this afternoon. The current expectation
is that the humidity won`t be as low as yesterday and will remain
above critical.

It should be noted there is the potential of a lower minimum humidity
than currently forecasted for this afternoon, if mixing of the dry air
aloft dominates. Watch closely for possible forecast updates today.
If conditions change, this spot forecast will be updated along
with the regional fire weather forecast.

Sufficient moisture should arrive in the area by Saturday to keep
humidities well above critical. Showers accompanying a cold front
through the state Saturday night and Sunday will bring to an end
the dry conditions and this round of elevated fire danger. Much
cooler weather with at least a couple rounds of showers is
anticipated for next week.
