Weather Summary for Iowa
National Weather Service Des Moines IA
442 AM CDT Fri Aug 18 2017

An area of low pressure in the northern Plains has sparked off some
showers and thunderstorms overnight, which were tracking into western
Iowa as of the early morning hours. The best chances to see some
shower and thunderstorm activity through the morning hours will likely
be in northern Iowa, as drier air works to break up the precipitation
further south. Any precipitation amounts will be light. Additional
isolated to scattered thunderstorm development is possible in central
and eastern Iowa this afternoon and evening as a front tracks through
the area, but widespread rainfall is not expected. Cloud cover will
impact the temperature forecast today. More extensive cloud cover will
limit highs to the mid to upper 70s in northern Iowa, while more
sunshine will warm temperatures into the 80s further south.

Dry conditions are likely through the weekend as high pressure takes
over. Heat and humidity return on Sunday as some parts of the area
reach into the 90s. The next low pressure system to cross through the
region will spark off showers and storms beginning Sunday night.
Chances for precipitation will continue into Monday and Monday night.
Cloud cover associated with this system may impact solar eclipse
viewing. The most likely area for expansive cloud cover will be
across northern Iowa with more scattered cloud cover further south.
Hot and humid conditions are likely where sunshine does occur. The
eclipse is still several days away, which leaves time for adjustments
to the forecast. Those with plans to view the eclipse should check for
forecast updates through the weekend.
