1:45AM: Steady showers continue to push across the Stateline, but wind gusts have come down a bit. A few spots may only see the gusty showers produce winds only up to 40 mph, remaining below severe limits.
12:40AM: Though it may not look all that impressive, the showers in Northwestern Illinois have been able to tap into stronger winds above the surface, producing wind gusts of 40-50 mph in some spots. While not severe, gusty winds may accompany the showers and storms overnight.
11:15PM RADAR: The two areas of storms are moving into Southern Wisconsin and Western Illinois respectively tonight, producing heavy rain and frequent lightning. Storms are sub-severe right now. Strongest storms may be able to produce a few strong gusts (up to 50 mph) from time to time as they move to the Northeast at around 50-60 mph. ETA for Southern storms to reach Rockford at current pace: about 1-1:30AM.
9:30PM UPDATE: We are watching two main areas of storms late this evening. The first in Iowa should push North of us into Central Wisconsin overnight. The 2nd round in Northern Missouri will move our way, likely after 12AM now. The later timeline of storms will aid in a weakening trend, limiting the potential severe risk locally. While we are not fully out of the woods, the chance for a severe storm with 60+ mph winds is diminishing. Showers will linger into the morning, but we will dry out by mid-day with temperatures falling to the 40s by the afternoon.
6:30PM RADAR: All remains mostly quiet across the Stateline, but the next window of storms is beginning to take shape across Missouri and Iowa. In the wake of the storms Friday morning, the atmosphere is a little more stable locally. This has kept us drier, while the main axis of storms develops South and East of us. Now through 10PM will continue the lull in precipitation, with only a small chance for an isolated storm.
An isolated cell may try to bubble up locally before 10PM, but the main window arrives between 10PM-2AM. Damaging winds and heavy rain will be the main threats, but a brief spin-up tornado could be possible as well.
The cluster or broken line of storms will enter Northwestern Illinois after 10-11PM, then center themselves along the I-39 corridor near or after 12AM. By 2-3AM, the strongest of the activity will have pushed off to the East, but steady showers or a few rumbles of thunder remain possible through 2-3AM. Be sure to have a way to receive warnings and make sure those warnings will wake you up since the storms will be coming in late tonight!
