Weather Summary for Iowa
National Weather Service Des Moines IA
457 AM CST Tue Jan 9 2018

Mid and high level cloudiness combined with a south wind at 5 to 15
mph helped to keep overnight temperatures in the mid 20s to mid 30s.
The warm temps combined with the recent snow melt helped to keep a
fair amount of low level moisture over Iowa that resulted in patchy
fog that reduced visibility to between 2 and 5 miles. Areas most
affected by fog were over the south and east.

The region is in for a couple more mild days today and Wednesday.
Wednesday night a strong cold front will push across the state towards
daybreak. Ahead of this front, warm and moist air will be in place and
rain will be developing across the southeast half of the Upper
Midwest. Across the northwest half, the front should make it far
enough such that precip will be in the form of snow. The forecast is
tricky because of the timing of this front through the region. For
some locations the front will pass through during the morning commute
and rain will change to a brief period of freezing rain then snow.
This will likely cause icy conditions Thursday morning. For locations
north and west of Iowa, winter storm watches have been posted for
several inches of snow, bitter cold temperatures moving in along with
strong wind, which will drop wind chill values. For the remainder of
the week and into the weekend, very cold air will return. Highs will
be in the single digits above zero north to teens south. Lows from
Friday on will in the single digits above and below zero region-wide.
The coldest look to be early next week.
