Weather Summary for Iowa
National Weather Service Des Moines IA
421 AM CST Sat Jan 21 2017

In almost a carbon copy from the previous few mornings, dense fog has
once again overtaken the region. A large upper level low pressure
area tracking across western Iowa continued to pump moisture from the
south into Iowa overnight. Fog continued into the morning hours for
much of southern to central Iowa. Visibility was a widespread quarter
to half a mile or less for much of the overnight period. Additionally,
widespread rainfall amounts of around one tenth to one quarter of an
inch were reported across central Iowa through mid-morning.With the
skies fogged or clouded over, temperatures remained nearly steady
overnight in the mid 30s to low 40s. At 4 am, the temperature in Des
Moines was 43 degrees, it was 39 in Waterloo, and the temperature at
Davenport was 45 degrees. Winds were generally from the east to
southeast at around 5 to 10 mph.

For the rest of today, similar to yesterday, foggy to hazy skies will
likely continue across much of Iowa...With the dense fog lifting
between 10 am and noon. Temperatures should be similar to where they
were yesterday across northern Iowa...with highs topping out in the
mid to upper 30s. Mid to upper 40s are likely across southern Iowa,
with a few locations possibly making it into the 50s. Rain should
push north of Iowa by around noon. Winds will become southwesterly at
around 5 to 10 mph.

Temperatures will not cool down very much behind the low, however, as
highs should remain in the mid 30s to mid 40s into the middle of next
week. The next best chance for widespread precipitation comes Tuesday
into Wendesday as another wintry weather system looks to pass through
the Midwest. Temperatures may cool down notably behind this system.
