Weather Summary for Iowa
National Weather Service Des Moines IA
448 AM CST Sun Feb 18 2018

It has been a quiet night across Iowa, with mostly clear skies and no
precipitation. Areas of fog have developed in light and variable
winds across much of eastern and northeastern Iowa, while in western
Iowa winds are from the southeast at 10 to 20 mph. Temperatures have
fallen into the lower teens northeast but are holding near freezing in
the southwest.

The fog should dissipate quickly after sunrise and southerly winds
will quickly increase from west to east across Iowa. It will be quite
windy by late morning, and wind advisories are in affect for about the
northwestern two thirds of the state. Despite the wind it will be
fairly mild, with highs in the lower 40s northeast to upper 50s
southwest. A winter storm system will then bring several rounds of
precipitation to Iowa and neighboring states from late tonight into
Tuesday. Freezing rain is likely across the northwestern half of Iowa
from late tonight into Monday, then a second round of freezing rain is
forecast in a broad swath from southwest to northeast across the state
Monday evening into Tuesday. This will lead to ice covered surfaces
and dangerous travel conditions at times, along with possibly tree
damage and power outages in some areas. Anyone with travel plans in
the region over the next couple of days should monitor forecast
updates and road conditions before setting out.

Behind the early week storm system Wednesday will be dry and notably
cooler, with highs only in the teens and 20s. Precipitation chances
will then return at intervals in the latter part of the week and into
next weekend.
