Wednesday Afternoon Update

April 27, 2016

Another round of showers are possible later tonight as they move from southwest to northeast. The trend is for them to fall apart as they move toward northeast Iowa and southwest Wisconsin. The gusty east wind continues tonight making the lows near 40° feel cooler.

Another round of scattered showers Thursday is going to be the last of this storm system. The wind gradually diminishes through the day and becomes light by evening. The rain ends by the evening hours as well, however the clouds linger through the night.

Friday turns out a little warmer with highs near 60 with dry conditions. It might not be sunny, but at least it will be dry.

We are tracking another storm system forecast to make our weekend a wet, breezy and cool one. The best chance of rain is Saturday afternoon through Saturday night. Scattered light showers will linger Sunday with a gusty east wind. The map below shows the rain forecast from Friday evening through Saturday evening.
