You can feel the humidity is already on the rise, and the big warm front pushes through tonight.

We had a decaying area of rain move through this afternoon, and there is a chance a few storms fire up tonight as the warm front passes through. The severe threat is low.

Watch: An Extreme Heat Watch has been issued for much of southern Wisconsin. Monday heat index values could top 105°F

Clearly, the big weather story this week is the heat as temperatures soar into the 90s on Monday, and the high humidity will make it feel like the 100s by the afternoon.

Tuesday may be even hotter.

The biggest forecast question remains: the position of the ring of fire. Some models keep ring of fire storms well to our north and scorching heat all week, while other model runs position the daily storms across southern Wisconsin by Wednesday, which would provide some heat relief. Either scenario would keep tropical humidity in place all week.
