1033 AM CST Tue Jan 10 2017
Early this morning, a large area of light rain was pushing into Iowa.
Rainfall amounts were generally one half inch or less in the areas of
heavier rain. With surface and sub surface temperatures at or below
freezing, the rain was freezing rain generally north of highway 30
causing travel difficulties for those areas. By late morning, colder
temperatures had filtered into northwest Iowa causing the light rain
to change over to all snow. Early morning low temperatures were in the
middle and upper 20s northwest to the lower and middle 40s south.
Southwest to west winds had shifted to the northwest across the
northwest half of the state by 1000 am and increased to 15 to 25 mph
with stronger gusts around 35 mph. By late morning, temperature over
the northwest had dropped into the upper teens and lower 20s. With
the stronger winds and colder temperatures, wind chills over northwest
Iowa had dropped into the single digits.
Low pressure over the central plains will continue to shift east
today. Big changes in the weather will occur behind this weather
system and moves into Wisconsin this afternoon. This will bring a
period of rain from central and southern Iowa into Illinois, but a
wintry mix of freezing rain, sleet and snow farther north into
Minnesota and Wisconsin before switching to all snow and ending west
to east this afternoon into the early evening. This may bring light
ice or snow accumulations and travel difficulties, including wind
gusts to 40 mph, to northern Iowa and adjacent states where Winter
Weather Advisories and wind advisories are in effect today.
Winter will become further entrenched across the region to end
the work week with more chances for light snow across the northern
plains into northern Iowa Wednesday into Thursday. Overnight lows are
expected to drop into the teens below zero north to single digits
above zero south by early Friday morning.
