Rain showers are ongoing across the Ohio Valley area extending into the Great Lakes region as a strong low pressure system sits over the Ohio/Pennsylvania area. This low is forecast to put down quite a bit of rain in the Great Lakes region over the next 24 hour period, with over 2.2'' of rain possible as per the HPC Rainfall Forecast below.
We can see just how much rain may accumulate in the Great Lakes, with Michigan, Indiana, and Ohio getting hit hard with totals exceeding .75 inches in portions of those states. Rainfall as a whole will cover the Northeast, Midwest and Ohio Valley even though rainfall totals will be lower... It is very possible there could be some flooding that may occur in Michigan and other areas due to this heavy rainfall in a short period of time, so be cautious of flooded roadways or nearby creeks and rivers that may suddenly swell due to heavy rain.
Much of Kansas and Oklahoma are under Freeze Warnings, with some type of cold-related bulletin covering portions of Arkansas, Missouri, Texas, Nebraska, and Colorado. Below are some forecast lows for tonight. The first image is for the eastern section of the Kansas/Oklahoma Border, while the second image is northeast Kansas.
Lows will dip into the mid 20's and bring a potentially killing freeze to much of the area. All plants must be covered if you want to save them, and ones that are not covered have a very likely chance that they could die from this freeze.
Chicago, Illinois and areas close to Lake Michigan are under high wind warnings as a strong low pressure system will move close to the region today, kicking up high winds and waves on the lake.
You can see the expected sustained wind speeds and expected wind gusts above in a table for Chicago. Below is the expected height of the wind speeds. Image is for wind gusts.
This image is valid for 1 AM tomorrow morning. Check out how Gary, Indiana will be getting 50 MPH wind gusts out of this! Boaters on Lake Michigan should take every precaution to not go boating in the next couple days, as waves will be over 25 feet high, with the occasional biggest waves at 34 feet.
