Gusty Winds for the Start of the Weekend

An incoming low pressure system for the start of the weekend will track northwest of northern Illinois late Friday night and early Saturday morning.  Winds ahead of the low will increase from the south helping to not only pull in a little more moisture, but also a warmer air mass.  This will keep temperatures in the mid 30's Friday night.

Rain showers are expected to develop overnight Friday in northern Illinois, but could mix with a few snow showers north of the state line by Saturday morning.  Low pressure will quickly move from the northern Plains into Wisconsin by Saturday, before heading into the eastern Great Lakes by Saturday night.

Winds ahead of the low Friday night will increase, gusting close to 40 mph through Saturday morning.  Following the passage of the low Saturday afternoon winds will shift around to the northwest, helping to pull down a cooler air mass through Saturday evening.


Most of the precipitation should be done by mid-day Saturday, but a brief period of a rain/snow mix or even a rain/graupel mix could occur by early afternoon.
