ROCKFORD (WREX) — Portions of the Stateline may see severe weather late this evening as strong storms slide in from Iowa. Jo Daviess, Carroll, and Stephenson counties are under the Tornado Watch until midnight, as storms from Iowa may bring severe weather, including tornadoes. The rest of the Stateline isn't out of the woods just yet.
Strong storms tonight:
So far today, we've seen numerous severe storms in Iowa, including a number of tornadoes. As those storms move eastward, they may hold together enough to keep the tornado threat going in the counties listed above. These storms are not expected to move in until after 10 pm tonight. Have a way to get severe weather alerts, like a weather radio or the 13 Weather Authority app.
As for the rest of the Stateline, the risks go down a little, but there's still a slight chance that flash flooding and damaging wind gusts are possible. The wind gusts may be strong enough to knock down large tree limbs. We'll say it again: have ways to get severe weather alerts tonight, even outside of the watch area.
In general, the line of storms arrives after 10 pm, and exits after midnight. We may not be done with storms just yet. More scattered showers and storms fire up late overnight, and could persist on-and-off through sunrise. While these storms should be weaker, multiple heavy downpours over the same locations could produce flash flooding. If you see water in the roads in the morning, find a different route.
More on the way:
The scattered showers and storms may keep going the next two days. The good news: we likely avoid strong storms, and there will be some breaks in the action.
Spotty showers bubble up at times Thursday morning, then the activity slowly shifts south. By the afternoon, most of the shower and storm chances are near and south of the I-88 corridor. Strong to severe storms should stay south of I-80 during the day, but stay alert just in case.
Friday has a chance for storms, but are more likely in the morning. The weather should slowly dry up as the day goes along.
By the weekend, sunny weather takes back over, and keeps going into next week. The added sunshine boosts our temperatures back into the 80's. We may rise to near 90 degrees by the middle of next week. The dry weather may stick around all of the next week, so rain could be hard to come by after this active stretch.
