...Icy Conditions Continue this Morning...
...Blizzard Conditions Develop This Evening Through Sunday...
.Freezing rain will persist until around 9 AM today for areas
north of Interstate 80. Temperatures will warm enough to change
some areas across central Iowa, including the Des Moines Metro,
Ames, and Webster City over to rain by mid-morning. The wintry
mix will persist however for northern and northwest Iowa through
the day. Travel difficulties will continue for areas where
freezing rain persists today.
By late afternoon and evening, much colder air will change
precipitation quickly over to snow from west to east across
central Iowa. Snow will become heavy at times this evening with
rates of 1 to 2 inches per hour likely from Omaha to Fort Dodge to
Webster City. Total snowfall of 6 to 10 inches likely along this
axis of heaviest snow. Strong winds will accompany the heavy snow
producing blizzard conditions. Snow amounts are expected to be
lighter south of this heavier axis, with generally 2 to 5 inches
expected from 2 to 5 inches from Waterloo to Des Moines towards SW
Iowa. Even so the combination of snow and very strong winds will
make travel difficult tonight. Although snow ends, winds will
continue to impact travel on Sunday.
There remains some uncertainty as to where the heaviest snow band
will set up Saturday afternoon and evening as the main storm
crosses Iowa. A small shift in the track of the storm will
greatly impact snow amounts and the extent of blizzard conditions
over the region tonight.
