Weather Summary for Iowa
National Weather Service Des Moines IA
512 PM CST Sun Jan 21 2018

Temperatures throughout Iowa today were still relatively warm. Central
Iowa saw afternoon highs reach into the mid 40s, with northern Iowa
seeing mid to upper 30s. Skies have been overcast across the state for
most of the day. The overcast skies have been accompanied by mist,
dense fog, and drizzle. Through this afternoon, winds have been rather
quiet, northeasterly at 5 to 10 miles per hour.

Across the rest of the Plains, rapid changes have been on going as a
low pressure system sweeps across the region. Temperatures have been
swinging from the mid 40s down into the mid 20s, and winds have
increased. Winter weather has started in central Nebraska, with snow
and mixed precipitation. This has resulted in difficult travel for
much of the Plains.

For this evening, a high-impact winter storm will move through
northwestern and northern Iowa, and will continue into Monday. Heavy
snow, coupled with gusty winds will result in Blizzard like conditions
for northwestern and northern Iowa. Amounts of 6 to 9 inches are
forecast for this area, with local amounts of 10 to 12 inches
possible. Travel will be extremely hazardous late this evening and
throughout Monday morning, if not impossible. Rain and drizzle in this
area is expected to transition to snow around the 3 to 4 AM time
frame. For central Iowa, rain and drizzle will continue overnight.
Snow accumulations in central Iowa range from just a dusting to 2
inches. The transition period from rain to snow could result in slick
road conditions toward the end of the morning rush hour commute.
Southern Iowa will see mostly rain from this event, with a few snow
flurries possible. If temperatures drop below freezing in certain
areas, there may be minor ice accumulations in central and southern
Iowa. This could add slight difficulty to travel.
