Blizzard Warning Expanded

A winter storm will bring moderate to heavy snow to portions of central Iowa through Friday night along with strong winds. The greatest threat for heavy snowfall is over north central and northwest Iowa.  Strong north to northwesterly winds will lead to dangerous travel during periods of heavier snow and conditions will reach or exceed blizzard criteria.

Rain early this evening is expected to transition to snow. The snow will be heavy at times tonight into Friday along with the potential for thundersnow. Snowfall rates of up to one inch per hour will be possible in the heaviest snow. Winds will also increase overnight from the northeast becoming northwest by Friday. Conditions are not expected to improve until Friday evening as the snow diminishes along with the winds.

Snowfall accumulations in the blizzard warning will be in the range of 6 to 12 inches. Winds will be sustained at 20 to 30-mph with gusts to 40-mph. Visibility will be reduced to one half mile or less for extended period of time with white-out conditions expected from time to time, especially in rural areas.
