Skies have been mostly cloudy for much of Monday afternoon but there have been some sunny breaks from time to time allowing temperatures to warm into the mid-40s, right where they should be for mid-November. Skies will remain mostly cloudy through the rest of the evening, despite what we currently see on radar.
There have been a few very light radar returns showing up over northern Illinois and southern Wisconsin but given the very dry air mass in place - dew points in the teens and 20s - none of what has been showing up has actually made it to the ground. And it'll be a while before we see any of those showers. But as we near Midnight the chance for rain should begin to increase as low pressure moves a little closer to the Midwest. In the very initial stages, there could even be a little graupel mixed in, but any wintry weather is expected to remain north of the state line. There could even be a few rumbles of thunder given a little instability aloft.
Most of the rain will be wrapping up by daybreak Tuesday with a few spots of drizzle lasting during the morning under mostly cloudy skies. Afternoon highs will remain in the mid-40s. Rainfall totals will likely stay between a tenth and a quarter of an inch.
A few days ago, it looked like we would be getting a pretty good soaking rain across the Midwest and Great Lakes late in the week, but over the last couple of days those rain chances have continued to dwindle. Low pressure currently off the southwest coast of California will move onshore over the next couple days, and eventually into the Plains and Midwest later in the week. At the same time another low-pressure system will move south from Canada into the Great Lakes. How fast that trough
