Weather Summary for Iowa
National Weather Service Des Moines IA
510 PM CDT Wed Sep 20 2017

Today a cold front has been working its way eastward through Iowa.
Throughout the afternoon ahead of the cold front, temperatures reached
the low 90s in the southeastern portion of the state, while central
Iowa recorded highs in the mid to upper 80s. Behind the cold front,
temperatures in northwest Iowa were mainly in the mid 70s. Winds ahead
of the cold front have generally been southwesterly at 10 miles per
hour, with breezy northwesterly winds behind the front. Mid to high
level clouds developed along the cold front, leading to partly cloudy
skies for south central and eastern Iowa. Late into the afternoon, a
few isolated thunder showers were observed along the front from
Waterloo southwest to Marshalltown, with visible satellite showing
the development of towering cumulus clouds.

Throughout the rest of the region, conditions were mild behind the
cold front. High temperatures throughout Minnesota and South Dakota
were in the low to mid 70s, with clear skies. Central Missouri and
central Illinois saw mostly clear skies with increasing cloud cover
as the cold front propagated eastward, with afternoon high
temperatures in the low 90s.

For tonight, isolated rain showers are possible along the cold front
for portions of central and eastern Iowa. Southeastern Iowa will
likely have the best opportunity for more widespread precipitation
overnight, including isolated thunderstorms. Low temperatures this
evening for central and eastern Iowa will be in the low to mid 60s,
with low temperatures in northwest Iowa dropping into the upper 50s.
However, the cool down will not last long, as southerly winds
Thursday afternoon will help high temperatures recover into the 80s
across the majority of the state.
