Heavy Snow and Strong Winds Possible Friday night into
.A late season snowstorm will impact parts of eastern Iowa and
northwestern Illinois Friday night into Saturday. The
precipitation will start out as rain or a rain/snow mix but
quickly change over to moderate, and at times, heavy snow.
The transition from rain to snow will take longer for areas south of a
line from Cedar Rapids to the Quad Cities. There will be a sharp
gradient in snowfall amounts on the southern and northern edges of
the swath of accumulating snow. Any shifts to the storm track
will greatly affect the snowfall forecast.
In addition to what is expected to be a wet heavy snow, easterly
winds are forecast to gust between 30-35 mph, creating
significant visibility restrictions and shallow drifting when
combined with the falling snow.
