Fire Weather Planning Forecast for Central/Southeast Illinois

.DISCUSSION...

Northeasterly winds continue today, and will generally be out of
the northeast on Friday, but wind speeds will be very light
Friday. Ventilation will be fair today, then poor on Friday as
the wind speeds weaken. Looking ahead to the weekend, a cold front
will move through on Saturday, shifting winds to northwesterly
and ushering in well below normal temperatures for Sunday into
early next week. Mixing deepens on Sunday, resulting in the best
ventilation of the next four days. Rain chances are low over the
next week, with the only notable chance being associated with the
front on Saturday (15%).
