A low pressure will move northeast along a boundary that is draped across west/central Illinois tonight. Scattered showers will develop ahead of this system which will affect mainly areas east of I-380. It'll be a cloudy and chilly night with many areas dropping into the 30s and low 40s.
Thursday the low pulls into the Great Lakes region and winds will be gusty out of the west/northwest. Much of the day will be cloudy with some possible sun late in the day, but it'll be a chilly one with temperatures in the upper 40s to lower 50s.
The break in the rain won't last long. Friday scattered showers develop once again and will track from south to north throughout the day. It'll be another chilly and rather raw day with readings again in the upper 40s to lower 50s.
Attention then turns to a powerful spring storm that will move through Iowa over the weekend. A surface low will develop in the southern plains and strengthen as it advances north into the region on Saturday. Winds will increase as rain develops late Saturday afternoon with periodic showers and thunderstorms lasting through Sunday. Heavy rains are likely with most areas picking up 1-2". Temperatures will be chilly on Saturday with most areas in the 40s. Model trends are tracking the storm a bit further to the northwest on Sunday which would bring in some warmer with highs possibly in the 60s south of Highway 30. However, if the storm were to track more over eastern Iowa then temperatures likely won't get out of the 40s, something we'll continue to watch.
The storm pulls away into Wisconsin on Monday with a few wrap around showers and cold temperatures again in the 40s and 50s.
Dry air and warmer weather return for the middle part of the week with readings back in the 60s.
