Weather Summary for Iowa
National Weather Service Des Moines IA
433 AM CST Mon Feb 20 2017

It has been a remarkably mild night across Iowa beneath mostly cloudy
skies. Winds have been from the southeast at 5 to 15 mph and
temperatures have remained in the upper 40s to mid 50s, which is
approximately 30 to 35 degrees above normal for this time of year. In
fact, at 2 am the temperature at Des Moines was only four degrees
below the record high for this date. Meanwhile, a large cluster of
showers and thunderstorms has moved from northeast Kansas into far
southwest Iowa at this hour.

It will be a mostly cloudy and rainy day but with record or near
record warmth in spite of periodic showers and thunderstorms. The rain
will clear out to the east this evening and tonight, with Tuesday and
Wednesday being sunny again and even warmer. On both days high
temperatures will range from lower 60s north to lower/mid-70s south.

Our incredible week of warmth will come to an abrupt end on Thursday
and Friday. A cool front will move through Iowa late Wednesday, then a
large and powerful storm system will spread rain and snow across the
state on Thursday night and Friday, with significant accumulations and
blowing snow possible especially north and west. Behind this storm
system, on Saturday high temperatures will only be in the 20s north to
mid 30s south, about 40 degrees colder than the Wednesday three days
