Weather Summary for Iowa
National Weather Service Des Moines IA
1115 AM CST Fri Feb 16 2018

The shift to northerly winds and clearing skies led to a drastic
temperature drop overnight across Iowa. Low temperatures in extreme
northwestern Iowa dropped below zero degrees, while central Iowa was
in the single digits and southern Iowa near 10 degrees. Wind chill
values were 10 to 15 degrees below zero with 10 to 15 mile per hour
winds. A few stations in northern Iowa reported snow flurries, but no
locations accumulated snow. By late morning, skies were still clear
with temperatures in the mid teens across most of Iowa.

Throughout the rest of the Great Plains and Midwest, temperatures
dropped with the northerly flow. Skies were mostly clear due the low
dewpoints with this cooler airmass.

For this afternoon, skies will remain mostly clear. Temperatures in
central and southern Iowa will be in the mid to upper 20s. A few
locations along the Iowa-Missouri border may hit 30 degrees. In
northern Iowa, temperatures will be in the upper teens to lower 20s.
The winds will gradually decrease this afternoon as they shift south-
westerly. This evening, cloud cover will begin to build. Temperatures
will not drastically drop this evening, with upper teens in northern
Iowa and lower 20s across central and southern Iowa. Across northern
Iowa, a few light snow showers are possible overnight and throughout
Saturday morning. Accumulations will not be substantial, from just a
dusting to half of an inch. Over the weekend, temperatures will
rebound back into the 40s across southern Iowa, with upper 30s across
northern Iowa. Starting off the next work week on Monday morning, a
dynamic system has the potential to bring a wide range of impactful
weather, with snow and freezing rain in portions of northwest Iowa,
and thunderstorms in southwest Iowa.
