CEDAR RAPIDS, Iowa (KCRG-TV9) - A low pressure system will lumber across the Midwest going into the weekend, bringing the potential for severe storms, heavy rain, and wet snow to eastern Iowa.
Scattered showers and thunderstorms are possible Thursday night as a warm front slowly lifts northward into Iowa. The best chance of that rain will be near and north of Highway 20. Occasional showers will persist in northern Iowa through the day Friday, but a good share of us will have a break in the rain late in the morning into the afternoon. That warm front will cause a big temperature spread – highs should stay in the 40s toward the Minnesota border, but may top 70 degrees again south of Interstate 80.
Additional thunderstorms arrive Friday evening into early Friday night. While the higher chance of severe weather will be west of the TV9 viewing area, some of the storms may still pack a punch as they move into our area. The main severe weather threat is large hail, although a tornado and gusty winds can’t be ruled out. Stay weather-aware Friday evening in case storms do turn severe.
Occasional rain will last into Saturday. By Saturday evening, rainfall totals over a half-inch are likely, and places near and north of Highway 20 have the best shot and getting more an inch. Local amounts over an inch and a half are possible.
Rain changes to wet snow Saturday night, continuing into Sunday. The heaviest snow will stay to our north in Minnesota. However, we can still expect some minor accumulation. As much as a couple of inches may fall in northern Iowa. However, just like the last snow, most of what we get will stick to the grass and elevated surfaces and not so much on the roads.
