Soaking Rain Coming
Another powerful upper level storm system is moving out of the four corners region of the US. This slow moving low will drag plenty of moisture north across Illinois and Wisconsin.
Severe weather won't happen out of this system with the lack of heating and instability; however, we will see some decent rainfall out of this event. Most of the area will pick up between 1.00" to 1.50" of rainfall. The rain looks to start Tuesday morning and last into Wednesday early afternoon. The heaviest axis of precipitation will arrive Tuesday afternoon into Tuesday night.
Flash Flood criteria will not be met with this system. The winds will strengthen Tuesday out of the southeast. It's possible that some gusts could approach 40 mph. As the low departs there will be several shots of cold air toward the end of the week into the weekend.
In fact we are watching a quick moving wave to arrive Saturday morning that could produce some light snow. Stay tuned!
