.DISCUSSION...
Southerly winds will become gusty by this afternoon, especially
along and west of the Mississippi River where gusts to 30 mph
are expected. These winds coupled with dry vegetation and warmer
temperatures will lead to very high fire danger for parts of
eastern Iowa. The gusty winds will continue area-wide on Sunday,
particularly in the morning. Lower end wetting rain chances
(20-40%) will develop later tonight into Sunday, especially
north/east of the Quad Cities. Very high fire danger will return
for the entire region on Monday in the wake of a cold front, as
northwest winds will turn gusty to around 40 mph.
The Grassland Fire Danger Index -GFDI- does not account for
precipitation that occurs or any snow on the ground. Please
make appropriate adjustments.
