Remember when 90° heat was stealing the headlines at the start of September? Now, just a few weeks later, we're talking about possibly record-breaking warmth as we head into the middle of October. That's where this week's weather story begins!
The reason for the potential record warmth today comes down to a favorable setup ahead of our next cold front. Conditions remain very dry across the region, and a strengthening southwest wind will help transport much warmer air into northern Illinois and southern Wisconsin. With plenty of October sunshine and little chances for rain, temperatures will have no trouble climbing into the mid 80s. That puts today's record high of 85° from 2008 in jeopardy.
Forecast models continue to show our next cold front pushing through early Tuesday morning, but with very little moisture available, its expected to sweep through dry. We do on the other hand see a round of slightly cooler air push in behind it. However, we're still expecting temperatures to climb to mild levels, landing in the upper 70s. As for the record books, the standing record high for tomorrow of 87 degrees will remain intact for another year.
As we move into the second half of the work week, temperatures will begin to cool while rain chances start to increase. A surge of atmospheric moisture is expected to move into the region on Thursday, giving us the ingredients for showers. Heaviest seems to occur to the south of I-88, but it will be important to keep up with trends the next few days.
