Weather Summary for Iowa
National Weather Service Des Moines IA
509 AM CDT Thu Mar 22 2018

Clouds are moving across Iowa early this morning with a mixture of
very light rain mixed with snow at times occurring from western Iowa
through the south central counties. Temperatures remain in the mid 20s
over the eastern portion of the state while milder readings are found
over the west where temperatures are in the mid 30s to lower 40s.  

A warm front will push east across Iowa today with the light rain snow
mixture ending later this morning or early afternoon. Warmer afternoon
temperatures are expected with highs ranging from the mid 40s over 
the northeast to the lower 60s in the far west today. Clouds will 
remain over the region tonight as milder air remains heading into the 
region. Friday will see big changes. A large storm system will bring 
abundant moisture into the Central Plains. Widespread rainfall is 
expected along with moderate to heavy wet snowfall over portions of 
northern, eastern and northeast Iowa, southern Minnesota, southwest 
Wisconsin and northwest Illinois. Snowfall totals may exceed 6 or more
inches with the heavier snow and winter storm watches have been 
posted for portions of northern Iowa and surrounding states. Over the 
remainder of Iowa, much of the precipitation will fall as rain. Over 
an inch of rainfall is possible. 

Highs Friday will be cooler over most of the area with high in the 
lower 40s north to the lower to mid 50s south. The storm will continue
into Saturday. As winds pick up over the region, falling snow and 
lower visibility may cause travel impacts over the region. After the
storm pulls east on Saturday highs will warm from Saturday into Sunday
back into the 30s northeast to the lower 50s southwest. Another storm
will affect the region Monday with more rainfall mixed with snow at
