... Winter Storm Warning...
* long term trends... the wintry mix and snow and sleet will continue late this afternoon and tonight before eventually transitioning to all snow late Thursday or early Friday. This change over to snow will be coincident with increasing north to northwest winds producing greatly reduced visibilities and near blizzard conditions.
* Total snow and ice accumulations... one to four tenths of an inch of ice may accumulate with the highest amounts along the Highway 20 and 30 corridors before the change to all snow. By the time the snow ends Saturday... should range from twelve to fourteen inches from Atlantic... to Webster City... to Hampton... with 14 to 20 inches northwest of a line from near Denison to Mason City. The higher amounts of that range should occur farther northwest toward Estherville.
* Winds... brisk east winds of 15 to 25 mph will be common through Thursday... however by Friday... winds will become northwest at 25 to 35 mph with higher gusts.
* Visibility... during the periods of heavy snow Thursday into Friday... visibilities will generally be less than one mile and even down to a quarter mile during the heaviest snows. White out near blizzard conditions may develop over northwest Iowa.
* Impacts... travel will become increasingly difficult in the warning area over the next several days and will likely be impossible by Friday as snow accumulates and winds increase. With around of foot of snow already on the ground in parts of northwest Iowa... snow depths may reach two to three feet by the weekend with drifts reaching rooftops of houses.
Precautionary/preparedness actions...
A Winter Weather Advisory means that periods of snow... sleet... or freezing rain will cause travel difficulties. Be prepared for slippery roads and limited visibility... and use caution while driving.
A Winter Storm Warning means significant amounts of snow... sleet... and ice are expected or occurring. Strong winds are also possible. This will make travel very hazardous or impossible.
