We are watching Wednesday closely for a potential severe weather threat in Illinois. Storm mode, wave timing, and early-day storms remain in question, but this dynamic of a system in June always raises eyebrows for possible severe storms. Stay tuned!

Temperatures will fall quickly once the sun sets amid a clearing sky. Overnight lows will push into the low 50s--if not upper 40s for some--despite a few passing clouds after 3-4AM. A refreshing night ahead!

7:13PM - A severe thunderstorm warning has been issued for portions of Whiteside, Henry, and Bureau Counties in Northwestern Illinois. This isolated storm may be able to produce 60 mph wind gusts and quarter sized hail as it moves East at about 20 mph.

Ironman racers and spectators are in for a real treat tomorrow as it will remain very cool for June standards, near ideal race conditions! No rain expected, with highs creeping through the 60s amid a moderate Northwest wind. Good luck to all the competitors!

4:32PM - This cluster has matured into a thunderstorm, producing a few lightning strikes between Amboy and Rochelle. Storm motion is still generally to the East at around 20-30 mph. Remember "when thunder roars, go indoors!"

4:15PM - A new isolated cluster of showers has developed across Lee County, moving East at around 20-30 mph. No lightning has developed yet, but may be possible over the next hour or two.

[First Warn Weather @FirstWarnWX]

This isolated storm has developed just Northwest of Rochelle over the last 20 minutes. While not showing signs of intensifying, it did produce one bolt of lightning. A brief shower and possibly an isolated clap of thunder will be the main products of this storm in the near term.

Scattered thunderstorms will be possible tomorrow, primarily after 3-4PM. Breezy Southwest winds will work to bring in moisture ahead of a cold front, which will initiate those storms. A few may be strong to severe with some instances of damaging winds and large hail possible.
