  gusting as high as 35 mph.

* WHERE...Portions of northern Indiana and southwest Michigan.

* WHEN...Until 7 PM EST /6 PM CST/ Thursday.

  evening. Areas of blowing snow are expected tonight into
  Thursday evening. The hazardous conditions will impact all
  commutes through Thursday evening.

* ADDITIONAL DETAILS...While a lull in the snow exists early
  tonight, the snow is expected to move back in for southeastern
  areas as another wave comes back in starting late tonight and
  early Thursday morning and continuing Thursday. The
  northwestern extent of this area of snow is uncertain as
  drier/colder air comes in and likely creates a sharp cutoff on
  that northern end. Additional accumulations of a trace to 3
  inches can be expected along with blowing and drifting of snow
  on east to west and mainly rural roads.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

This storm will bring dangerous driving conditions through
Thursday. Unplowed roads are likely to become impassable in many
areas. Plummeting wind chills accompanied by blowing and drifting
snow could bring a potentially lethal travel situation with wind
chills falling below zero if you become stuck in your vehicle
later Thursday/Thursday night. Plan now to make any needed travel
changes to avoid travel during this time. Monitor the latest
forecasts for updates on this winter storm. If you must travel,
keep an extra flashlight, food, and water in your vehicle in case
of an emergency.
