.DISCUSSION...
A low pressure system in the Great Lakes region will be responsible
for gusty northwest winds today, as well as clouds and some flurries
in eastern Missouri and western IL this morning. Clouds will clear
from west to east as the day progresses. The gusty winds, combined
with dry fuels, and low afternoon relative humidity values will
result in a heightened fire danger this afternoon for parts of central
