Weather Summary for Iowa
National Weather Service Des Moines IA
1045 AM CDT Mon Mar 19 2018

While there was a fair amount of clouds overnight, much of Iowa saw
sunshine this morning as the work week got underway. Overnight lows
were on the chilly to mild side ranging from the upper 20s under clear
skies to the mid 30s under the cloudier skies across the southwest. 
By late this morning northeasterly winds were working to try and keep 
temperatures down a bit, but they were still able to rise a few 
degrees from morning lows into the upper 30s to mid 40s in most 

Overall today will be fairly pleasant as with partly cloudy skies much
of the day, before clouding over the state this evening. Temperatures
should have little issue reaching into the mid 40s to low 50s across
most of the state. Parts of far northwest Iowa may not get much past
40, while parts of far southern and southeast Iowa may creep into the
mid 50s. Rain opportunities should remain just outside of the state
today to the west and south. That will begin to change overnight
though as a weak system slides in from the west that will bring in
cooler air and an opportunity for some light snow accumulations over
western and northwest Iowa. The greatest amounts should remain in the
northwest, where as much as 3 inches may fall. Through the morning
Tuesday the light snow will continue to slide eastward and with 
temperatures warming above freezing many will see a change over to 
light rain. Tuesday will also be the coldest day of the week with
highs only in the mid 30s to low 40s.

The remainder of the week will see temperatures rebound a bit with mid
40s to 50s across Iowa by Thursday and into the first half of the
weekend. After tonight and Tuesday, the next best opportunity for
precipitation looks to move through Friday into Saturday. Some light
snow may be seen early Friday morning, but as temperatures rise,
precipitation will turn to all rain.
