Significant storm system is ahead late Friday to Saturday night.

Southeast to south winds may gust 30-40 mph Friday night-Saturday morning.

Northwest winds Saturday evening may gust 40-50 mph.

Friday evening, some snow should reach western Benton, Warren to Newton counties 5-6 p.m.

It will then overspread the area, but turn to sleet, then freezing rain relatively quickly.

Blue is snow, red color is sleet, purple is freezing rain & green rain:

Ice should change to rain by 1 a.m. in our southwestern counties, then the entire viewing area got to rain by 4 a.m.

Rain should end as some snow Saturday midday-afternoon.

1" or less of snowfall is possible before changing to ice.  Another less than 1" is possible Saturday as rain ends as snow.

Up to 0.15" of glaze ice & 0.1" of sleet is possible.  Icy roadways are likely Friday evening to Friday night before ice changs to rain as temperatures rise from 29-32 to 37-45.

0.75-1.50" of total liquid is possible.

This may cause rivers to rise again Sunday-Monday above flood stage.

The coldest air of the winter so far should arrive Sunday-Sunday night with bitter wind chills & well-below normal temperatures, even without much snow pack at all here.  It would be much colder if we had a snow pack.

With a snow pack, parts of Iowa may drop to -27 Monday night.  Part of our area will drop to 0.

Wind chills may drop to as low as -20 in the area Sunday morning.
