ILLINOIS — A cluster of non-severe storms is currently moving across the Rockford, Dixon and Mendota area this Fourth of July morning, with heavy rain and frequent lightning standing out as the biggest hazards. These storms should clear the region by 10 a.m. Heading into the afternoon, scattered thunderstorms are expected to develop as early as noon, with the highest storm threat located south of I-80, though an isolated severe storm cannot be entirely ruled out elsewhere.
Morning Storm Cluster Brings Heavy Rain and Lightning
Radar shows an active cluster of storms tracking through Freeport, Rockford, Byron, Oregon, Dixon and Amboy this morning, producing locally heavy rainfall and frequent lightning. Additional activity is visible pushing through Mendota and Princeton as the cluster continues moving southeast.
This morning round is considered non-severe, with the main concerns being downpours and lightning rather than damaging winds or hail. Coverage should wind down by around 10 a.m.
Afternoon Storms Develop With Isolated Severe Potential South of I-80
Scattered thunderstorms are expected to redevelop heading into the afternoon, with some activity possible as early as noon. The primary window for afternoon storms runs between 12 or 1 p.m. through 7 to 9 p.m., with any individual storm expected to last no more than a couple hours at one location.
The highest threat for stronger storms sits south of I-80, though isolated severe storms remain possible farther north as well.
Evening Coverage Expected to Wind Down but Not End Completely
Storm coverage is expected to decrease heading into the late evening, though some showers and isolated storms should still linger through around 10 p.m. This evening round is not expected to match the widespread coverage seen Friday evening.
Timing and Location of Storms Remains Uncertain
Forecasters caution it remains difficult to pinpoint exactly where scattered activity will develop through the day. While not expected to be a complete washout, residents should monitor radar and forecasts closely and have a plan to seek shelter quickly if a storm moves into their area.
