URGENT - WINTER WEATHER MESSAGE
National Weather Service Des Moines IA
335 AM CST Wed Feb 3 2021

...Significant Travel Impacts Thursday into Thursday Night...

.A powerful cold front moves through the area Thursday morning and
afternoon bringing strong northwest winds, falling temperatures, 
wintry precipitation. Significant impacts to travel conditions are
likely through the rest of day into Thursday night due to a 
variety of contributing factors. Scattered precipitation will 
initially start as rain or drizzle tonight into Thursday morning 
before the front quickly crosses the area from west to east. Any 
wet or slushy roads may flash freeze and quickly become icy as 
temperatures fall. Strong northwest winds gusting above 45 mph 
will create widespread blowing snow and potential blizzard 
conditions at times, especially in rural areas of north central 
into central Iowa. Snowfall totals are not expected to be heavy, 
but even light amounts may be enough to worsen impacts. Wind 
chills fall below zero by Thursday evening into Thursday night, 
which could serve as another hazard should motorists become 
stranded. Those with travel plans are highly encouraged to closely
monitor for changing weather conditions and consider alternate 
plans if at all possible. Late afternoon and evening commuters 
should note that conditions may be dramatically worse compared to 
the morning hours.

URGENT - WINTER WEATHER MESSAGE
National Weather Service Des Moines IA
245 AM CST Thu Feb 4 2021

...Significant Travel Impacts Today into Tonight...

.A powerful cold front will move through the area today with 
strong northwest winds, falling temperatures and wintry 
precipitation. Significant impacts to travel conditions will
occur. Precipitation will initially start as rain or drizzle 
early this morning just ahead of the fast moving front and quickly
transition to moderate snow with very low visibility this morning.
Wet or slushy roads may flash freeze and quickly become icy as 
temperatures fall this morning. 

Strong northwest winds gusting above 45 mph will create widespread
blowing snow and blizzard conditions at times the remainder of 
the day into this evening, especially in rural areas of north 
central into central Iowa. Snowfall totals are not expected to be 
heavy, but even light amounts may be enough to worsen impacts. 
Wind chills fall below zero by this evening into tonight, which 
could serve as another hazard should motorists become stranded.
