Winter Storm Warning
Issued by the National Weather Service at 3:17 am CST on February 9, 2010
... Winter Storm Warning now in effect until 9 am CST Wednesday...
The Winter Storm Warning is now 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 8 to 12 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 to 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 is likely to be significantly hampered by the
snow storm... including this morning's rush hour and particularly
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.
