Weather Summary for Iowa
National Weather Service Des Moines IA
514 PM CDT Sat Oct 21 2017

A cold front sweeping across the upper Midwest has broken the pattern
of calm Fall weather across Iowa. Cloud cover drastically increased
throughout the morning and afternoon. High temperatures were in the
mid 70s, except for northwest Iowa where temperatures struggled to
hit 60 as the cold front passed through. Thunderstorms have initiated
in the late afternoon hours along the cold front in western Iowa, and
have been moving eastward across the state bringing heavy rain and
gusty winds. Ahead of this line, there have been a few isolated
showers in central and eastern Iowa. As of the early evening, this
line of thunderstorms has continued to increase in strength, however,
they have not reached severe limits yet. But the environment is still
favorable for storms along this line to become severe.

Across the rest of the region, this wave has brought wide spread
cloud cover and isolated rain showers and thunderstorms. As of the
early evening, the only severe weather has occurred in northeast
Kansas and northwest Missouri.

For the rest of this evening, this line of thunderstorms will sweep
across all of Iowa, brining heavy rain and gusty winds. There is still
a chance for potions of the line to become severe. After the cold
front passes, there will be chance for rain showers throughout the
rest of the evening. Overnight low temperatures will be in the mid 40s
to lower 50s. For tomorrow, temperatures across will be much cooler,
with high temperatures in the upper 50s to lower 60s. Skies should be
mostly clear as high pressure begins to build in after the passage of
tonight`s cold front.
