... Freezing Rain Advisory remains in effect until noon CST Wednesday... ... Winter Storm Watch remains in effect from Wednesday afternoon through Friday afternoon...
A Freezing Rain Advisory remains in effect until noon CST Wednesday. A Winter Storm Watch remains in effect from Wednesday afternoon through Friday afternoon.
... Freezing Rain Advisory...
* timing... patchy freezing drizzle will continue across much of northern into central Iowa through the early morning hours on Wednesday. Some light glazing is expected... especially on less traveled roads.
* Total ice accumulations... around a tenth of inch of ice accumulation is expected through midday Wednesday.
* Visibility... the freezing drizzle will combine with areas of fog to reduce visibilities to less than one mile in areas.
* Impacts... travel will be hazardous with areas of black ice... especially on less treated roads. It will take only very minor ice accumulations to cause travel difficulties. In addition... the ice can be difficult to see on the Road... so a Road that appears to be clear may actually be icy.
... Winter Storm Watch...
* timing... the most significant impacts with this storm should occur from Wednesday afternoon through Friday.
* Storm total ice accumulations... icing of up to one quarter of an inch is expected from the Highway 30 to Highway 20 corridors through Thursday with lesser amounts either side of those areas.
* Storm total snow accumulations... the precipitation should become primarily snow late Thursday into Friday with total accumulations by the end of the storm from 2 to 6 inches from Atlantic... Des Moines and Grinnell... up to over a foot along and west of a Denison... to Fort Dodge... to Mason City line.
* Winds... brisk east winds of 15 to 25 mph will be common Wednesday into Thursday. 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. With increasing winds and snow coincident by Friday... blowing snow and greatly reduced visibilities near blizzard conditions are expected by that time especially west of Interstate 35.
* Impacts... travel will become increasingly difficult in the watch area on Wednesday during the wintry mix of precipitation and continue to be difficult into Thursday and Friday as snow accumulates and winds increase. In the heaviest snow areas... travel may become nearly impossible due to blowing and drifting snow Thursday night into Friday.
