Weather Summary for Iowa
National Weather Service Des Moines IA
1054 AM CDT Tue Apr 18 2017
The first in a series of storm systems to impact the state was moving
over the Northern Plains Tuesday morning, which was helping to push a
line of showers through the state. As of 11 AM the line stretched from
northeast Iowa, down through the Des Moines metro and into the
southwest corner of the state. The showers will gradually dissipate as
they push east during the afternoon hours. The redevelopment of
showers and storms is likely this evening and overnight, generally in
the vicinity of a front that will stall out over the central and
southern portions of the state. Some of the storms overnight may
produce heavy rainfall.
Additional thunderstorm activity is likely Wednesday, some of which
may be severe during the afternoon and evening hours capable of
producing large hail and damaging winds. A tornado or two cannot be
ruled out, but overall the threat for tornadoes will be low.
Conditions will dry out for Thursday and Friday, although highs will
be cooler in the mid 50s to low 60s. Chances for light rain return to
the southern half of the state for Saturday, but otherwise the weekend
looks dry with highs holding around 60 degrees.
