URGENT - WINTER WEATHER MESSAGE
National Weather Service Quad Cities IA IL
256 PM CST Wed Feb 3 2021

...Impactful Winter Storm Thursday...

.A fast moving Arctic cold front will bring dangerous conditions 
to portions of the area Thursday and Thursday night. Rain mixed 
with freezing rain and sleet will move into eastern Iowa early 
Thursday morning, then as the cold front moves in from the west 
during the mid morning, the rain will switch to snow. The winds 
will increase to 35 mph behind the front, and any wet roads will 
flash freeze. As the front moves east, this same impact will occur
with it, reaching the Mississippi River in the early afternoon, 
and central Illinois by late afternoon.

Snow is expected to fall for several hours after the change over
and become heavy at times, with several inches expected to fall. 
Winds behind the front will increase to 25 to 35 mph with gusts up
to 45 mph during the afternoon and evening, with blowing snow 
becoming dangerous in open areas. White out conditions are 
possible in open areas, and some areas may experience periods of 
near blizzard conditions, especially across east central and 
northeast Iowa. Significant drifting snow will be a problem 
through Friday morning. Wind chills will drop to 5 below to 15
below zero late Thursday night along and north of I80, and will be
very dangerous to anyone stranded out in the storm.

URGENT - WINTER WEATHER MESSAGE
National Weather Service Quad Cities IA IL
220 AM CST Thu Feb 4 2021

...Snow and Blowing Snow...

.A fast moving Arctic cold front will bring dangerous conditions
to portions of the area today and tonight. Rain, possibly mixed 
with freezing rain and sleet will move into eastern Iowa early 
this morning, then as the cold front moves in from the west 
during the mid morning, the rain will switch to snow. Strong winds
and falling temperatures behind the front will cause any wet 
roads to quickly freeze. As the front moves east, this same impact
will occur with it, reaching the Mississippi River around noon, 
and central Illinois by mid afternoon.

Snow is expected to fall for several hours after the change over
and become heavy at times, with several inches expected to fall.
Winds behind the front will increase to 25 to 35 mph with gusts
up to 45 mph during the afternoon and evening, with blowing snow
becoming dangerous in open areas. White out conditions are
possible in open areas, and some areas may experience periods of
near blizzard conditions, especially across east central and
northeast Iowa. Significant drifting snow will be a problem
through Friday morning. Wind chills will drop to 5 below to
15 below zero late Thursday night along and north of I80, and
will be very dangerous to anyone stranded out in the storm.

URGENT - WINTER WEATHER MESSAGE
National Weather Service Quad Cities IA IL
838 PM CST Thu Feb 4 2021

...Strong Winds, Blowing and Drifting Snow Continue as Accumulating
Snow Ends...

.Accumulating snow has ended across the area. However, hazardous
travel will persist the rest of tonight. Strong northwest winds 
at 20 to 30 mph with gusts up to 40 mph will continue to produce
considerable blowing and drifting of snow tonight. The blowing
snow will bring reduced visibility and potentially near white out
conditions at times, especially in rural and open areas. 
The combination of the snow covered and slick roadways along 
with drifting and significant visibility reductions at times will
continue to make travel hazardous. Wind chills will drop to 5 
below to 15 below zero late tonight along and north of I80, and 
will be very dangerous to anyone stranded out in the storm.
