...BLIZZARD WARNING REMAINS IN EFFECT UNTIL MIDNIGHT CST
TONIGHT...

* SHORT TERM TRENDS...Light to moderate snow will taper off
  sharply from west to east through late evening. Strong
  northwesterly winds of 15 to 25 mph with some gusts, will
  diminish some through the evening to 10 to 20 mph toward
  midnight. Improvement in the blizzard conditions is expected as
  the snow ends from west to east through late evening. 

* ADDITIONAL SNOW ACCUMULATIONS...1 inch or less.

* WINDS/VISIBILITY...Northerly winds at 15 to 25 mph with gusts up
  to 30 mph. Visibility will be reduced to around a half mile to
  one mile before the snow ends by late evening, with near zero
  visibilities at times mainly in rural areas.
  

* IMPACTS...Travel will remain hazardous as blowing snow reduces 
  visibility. Many tow bans remain in effect across northern Iowa.
  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Blizzard Warning means severe winter weather conditions are
expected or occurring. Falling and blowing snow with strong winds
and poor visibilities are likely. This will lead to whiteout
conditions, making travel extremely dangerous. Do not travel. If
you must travel, have a winter survival kit with you. If you get
stranded, stay with your vehicle.

...WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL MIDNIGHT CST
TONIGHT...

* SHORT TERM TRENDS...Light to moderate snow will taper off from
  west to east through late evening. Visibilities will be
  relatively poor with icy, snow-covered roads expected into the 
  evening hours. 

* TOTAL SNOW ACCUMULATIONS...1 to 2 inches.

* WINDS/VISIBILITY...North winds at 15 to 25 mph are expected with
  gusts to around 30 mph from time to time. Visibilities below 
  one mile are expected with brief periods where visibilities may 
  drop below one quarter of a mile, mainly in rural areas. 

* IMPACTS...Roadways may initially develop minor icing and then 
  become snow covered as sunset approaches. The snow and blowing 
  snow will reduce visibility creating hazardous travel 
  conditions. Slow down during the evening commute and travel 
  cautiously. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Weather Advisory for snow and blowing snow means that
roads may become slick with visibilities then limited due to
strong winds blowing snow. Use caution when traveling.
