It is going to be a wet couple of days here in the state of Iowa. We will first start off with rain pushing north into the state later on this evening and will continue to through the day tomorrow. Rain will then begin to transition over to snow Thursday evening across northwest Iowa. This is where the heaviest snowfall will accumulate. Because of this, the National Weather Service has issued winter storm warnings, and winter weather advisories.
A WINTER WEATHER ADVISORY is in effect from 7pm Thursday to 7am Friday for northwest Iowa. By Thursday evening, rain will quickly change to snow, which will linger through Friday morning. Periods of moderate to briefly heavy snow will be likely during the evening and overnight hours of Thursday into Friday morning. Accumulations of 2 to 5 inches will be likely. A north to northwest wind will increase to 20 to 30mph by Thursday afternoon, and last that way into Friday morning. This will reduce visibilities to around a half mile at times.
A WINTER STORM WARNING is in effect from 4pm Thursday to 7am Friday. Rain and drizzle will become more likely through Thursday morning, before quickly transitioning to snow mid afternoon Thursday. The snowfall will be moderate to heavy at times, especially from about 5pm through 12am. Snowfall rates of an inch per hour will be likely which may cause a messy late evening commute home Thursday evening. Snow and blowing snow will linger through Friday morning. Accumulations of 6 to 10 inches will be possible with the heaviest amounts along and east of interstate 29. North to northwest winds will average 25 to 35mph Thursday night and Friday morning. Winds of this magnitude could create greatly reduced visibilities and drifting of snow.
From the image above you can see where the heaviest snowfall will accumulate. Lesser amounts will be possible from western to central Iowa. We will continue to keep an eye on this system and will bring you the very latest information on our Facebook and Twitter pages, and of course right here at iowachase.com.
