... Winter Storm Warning remains in effect until 9 am CST
Wednesday...

A Winter Storm Warning remains in effect until 9 am CST
Wednesday.

* Timing... snow will continue into this evening... with snow
likely becoming heavy at times this afternoon into the early
evening hours. Considerable blowing and drifting of the
freshly fallen snow is likely tonight into very early
Wednesday morning.

* Accumulations... light to moderate snowfall this morning into the
early afternoon will result in hourly snowfall rates of
generally a half inch or less. Localized lake enhancement of the
snowfall is likely this afternoon into the early evening
resulting in periods of heavy snow with snowfall rates reaching
an inch or more per hour at times. A storm total by late tonight
of 7 to 11 inches is expected... though the lake enhancement of
the snow may result in locally heavier amounts.

* Hazards... in addition to the long duration accumulating
snowfall... northwest winds will increase to 15 to 25 mph with
gusts between 30 and 35 mph tonight into early Wednesday morning
resulting in considerable blowing and drifting
snow... particularly in more open and outlying areas. The
potential exists for near ground blizzard conditions in rural
areas tonight into early Wednesday morning.

* Impacts... travel will continue to be significantly hampered by
the snow storm... especially during this evening's rush hour.
Snow may fall heavily enough at times this afternoon and early
evening that even major roads and highways could become snow
covered. Blowing and drifting snow tonight will result in near
ground blizzard conditions in outlying areas making travel very
dangerous. The snow storm is also severely affecting air travel
with hundreds of flights already cancelled to and from Chicago.

Precautionary/preparedness actions...

A Winter Storm Warning means significant amounts of snow...
sleet... ice... or strong winds are expected or occurring. This
will make travel very hazardous or impossible. If you must
travel... keep an extra flashlight... food... and water in your
vehicle in case of an emergency.
