Weather Summary for Iowa
National Weather Service Des Moines IA
549 PM CDT Fri Mar 16 2018

This afternoon was not nearly as nice as the past couple of days
across Iowa. A system moving through the area has drastically
increased cloud cover, leaving overcast conditions for most Iowa
today. High temperatures reached the mid to upper 30s. Winds have 
been easterly at 15 to 20 miles per hour. Rain showers have been 
slowly moving northward across Iowa. A few locations have reported 
thunder with these showers. By early evening, radar indicated a line 
of rain showers from Fort Dodge southeast across the Des Moines metro 
and into Ottumwa. There have been several reports of ice pellets and 
sleet mixed in with this rain. Temperatures around 530 PM were in the 
mid 30s across Iowa. 

Conditions across the Great Plains have been mostly cloudy as this
system continues to develop. Wintry precipitation has been reported
across northern Nebraska, with rain showers in Missouri. This system
has resulted in a drastic temperature contrast across the region, with
mid to upper 60s in portions of Kansas and Missouri, to mid 30s across
Nebraska and Iowa. 

For the rest of this evening, wintry mixed precipitation will 
continue throughout most of the state. Temperatures overnight will 
hover right around the freezing benchmark of 32 degrees. For portions 
of northern and eastern Iowa, travel conditions will become slick 
overnight and into Saturday morning. After this system passes, Iowa 
will see a brief dry period, and temperatures will slowly recover 
back into the 40s. However, the weather pattern becomes active at the 
start of the next work week, with a few systems forecast to move 
across the area that will bring several rain showers.
