Blizzard Warning
...STRONG WINDS, SNOW, AND FALLING TEMPERATURES LEADING TO
HAZARDOUS TRAVEL TODAY...
.Strong northwesterly winds with gusts over 55 mph continue to
produce dangerous travel conditions in northern and north central
Iowa today as both falling and freshly fallen snow continues to blow
around. Visibilities of a quarter mile or less have been common in
these areas. Additional rounds of snowfall through the afternoon and
evening will prolong these deteriorated conditions, with strong
winds expected to continue into Monday morning. Freezing
temperatures have now switched snow over to rain in central and
south central Iowa, leading to slushy and slick roadways. Additional
snowfall tracking from west to east over this area, as well as gusty
winds, will continue to impact travel, especially on rural and
untreated roads.
* WHAT...Blizzard conditions. Additional snow accumulations of 1 to
3 inches. Winds gusting as high as 55 mph.
* WHERE...Portions of northern and north central Iowa.
* WHEN...Until 9 AM CST Monday.
* IMPACTS...Plan on slippery road conditions. Areas of blowing snow
could significantly reduce visibility. The hazardous conditions
could impact the Monday morning commute. Gusty winds could bring

conditions. Farther south into north central and central Iowa, rain
will transition to snow as temperatures drop below freezing,
resulting in re-freeze potential. Similarly, bursts of snow will
lead to short durations of visibility under a mile, which combined
with freezing roads could make travel dangerous. Accumulations will
