Thursday: Expect fog to gradually lift after 8 AM as sunshine and daytime heating help break up the fog. Make sure to have the sunglasses handy as sunny to mostly sunny skies will dominate much of the workday’s sky. Temperatures will be warmer today due to southwesterly winds driving in warmer air. Daytime highs will reach the mid to upper 80′s across the region. It may even feel a bit humid this afternoon due to added moisture from Wednesday’s rainfall.

The Next Big Thing: We’ve been discussing the potential for strong to severe storms on Friday evening throughout the week, but some changes are possible in the forecast. Here’s our latest thinking.

With new model data coming in, our confidence in severe weather potential has gone down a bit. As Chief Meteorologist Brian Walder mentioned Wednesday evening, there are two limiting factors in place for thunderstorm development. First will be the timing and location of the cold front’s passage. Models trend the front to pass during the afternoon rather than the evening locally, which would have it passing during a period when the atmosphere is more capped. We would still be able to see some showers and storms develop, but this cap would limit our severe storm potential.

A few showers and storms will still be possible Friday.

While the potential for severe storms is lower, they are still possible, especially east of the Illinois River. If we do see any severe weather, strong winds and large hail will be our primary threats. Additional rainfall will be possible through Saturday.
