Weather Summary for Iowa
National Weather Service Des Moines IA
1042 AM CDT Wed Mar 21 2018

The eastern half or so of Iowa woke up to clear skies and chilly
temperatures, while the western half saw cloudy skies and milder
overnight lows. The lows ranged from the low to mid 20s roughly east
of Interstate 35 to the upper 20s to mid 30s in areas to the west.
Other than the clouds and chilly temperatures, it was an otherwise
quiet overnight period. So far this morning, much of the same has
continued to start the day. Clouds have primarily stayed west of
Interstate 35, but have started to slowly slide eastward and dissipate
across southern areas. Temperatures had risen above freezing over the
clear sky areas, while those that remain under clouds had only warmed
a degree or two above their morning lows.

Today and tomorrow will predominantly be quiet and warmer than
yesterday. Highs will work their way into the 40s across most of Iowa
today, and then a few degrees warmer Thursday into the upper 40s and
50s. Even with the warmer temperatures Thursday, a quick moving small
system will bring about some brief rain and snow chances over roughly
the southern half of the state tomorrow. The snow will be held to the
colder morning hours before turning to all rain during the daytime

A bigger, more potent system will affect the region Friday and
Saturday bringing with it cooler temperatures and potential for
moderate rainfall and accumulating snow. The best opportunity for
accumulating snowfall will be over the northeast third of the state or
so, where there may be potential for 3 to 5 inches of snow or more.
Areas further south will be warm enough for rain to prevail, but could
see amounts in excess of half an inch to an inch in some cases
through Saturday night.
