Weather Summary for Iowa
National Weather Service Des Moines IA
1004 AM CST Wed Dec 12 2018

Fairly mild conditions prevailed overnight, at least by recent
standards. Overnight lows were below freezing, but they were generally
in the mid to upper 20s across much of the state. Northwest Iowa was
the coldest though, with some areas dipping down into the teens.
Conditions through the morning also varied a bit, with some low cloud
cover across large parts of northeast, northern, and central Iowa,
which was also providing a bit of freezing drizzle. 

Clouds will dissipate some through the morning and afternoon,
especially across the south, but will likely move back in once again
this evening. Otherwise, the only notable weather over the next few
days will slide into portions of southern and eastern Iowa from the
south Thursday morning and on through the day. Precipitation will
likely begin as light freezing rain or drizzle during the early
morning, transition to cold rain, and then back to snow during the
evening hours. Temperatures over the next few days will generally be
on the mild side, with a warming trend into the weekend. Highs by the
weekend may reach 40 across the majority of the state, with mid to
upper 40s potentially through central and southern Iowa.
