Winter Weather Advisories are in effect overnight for freezing rain, sleet and light snow. Winter Weather Advisories and High Wind Watches are in effect Saturday evening through Sunday evening ahead of a powerful winter storm that will bring heavy rain, snow and strong wind gusts up to 50mph.
A strong winter storm will take shape to our southwest and move into the area tonight. After 11 pm there will be freezing rain, sleet and snow. Accumulating snow will be confined to the far north where 1" is possible. Elsewhere, a glaze to .10" of ice accumulation is possible. This will create hazardous travel conditions with slick roadways.
Warmer air will move in Saturday morning, and temperatures will rise above freezing. Precipitation will change to all rain across most of the area. There may still be some areas of freezing rain in the far north. Temperatures will be in the 30s in the afternoon. Then colder air will begin to wrap in behind the storm and that will change precipitation over to snow Saturday night into Sunday.
The track of this storm will be incredibly important in determining the impacts, concerning heavy snow and strong winds. Some snowfall accumulation is possible in eastern Iowa, the highest chance rain now is in the northwestern parts of the area. Any changes in the track will change where the heavy snow falls.
Regardless it will be colder and windy Sunday with temperatures falling through the day. Winds will pick up with some gusts of 40-50 mph through Sunday. This wind, combined with heavy snow, will lead to a significant blizzard in parts of Iowa. This will lead to significant travel impacts which could render travel nearly impossible. The highest risk for this will be west of eastern Iowa and may clip our far northern and northwestern counties.
An Arctic front will slide through early next week bringing much colder air with high temperatures only in the teens and night lows near zero. There will be the chance for some light snow showers on Wednesday.
