.DISCUSSION...

Northwest winds weaken to around 7-10 mph with gusts around 15 mph
by ignition time, further weakening by late evening to around 5
mph from the west. The one concern to watch will be the potential
for some brief and isolated showers moving southeast from
Nebraska. These won`t put down much rain, but could bring some
brief gusty winds to around 30-35 mph if one goes right overhead.
Otherwise, RH gradually increases from around 25-30 percent around
ignition to around 50 percent by midnight.
