Active weather pattern in store, though severe weather potential looks slim to none

An active weather pattern starts for our area this morning, Tuesday, April 22, 2025, as multiple low pressure storm systems move over or close to southeast Wisconsin. While none of them look to be very strong, they do pose a risk of scattered off and on showers and an occasional rumble of thunder through the end of the week.

The first system is weakening as it moves to our northwest, centered over northern Minnesota today. An area of showers accompanying this low will make its way through this morning, with rain chances ending around noon.

As this low slowly makes its way to the northeast, a weak warm front will pass over, and with light southerly winds, we’ll see temperatures climb into the upper 50s for a high today. This front looks to stall somewhere over Wisconsin which will be the focus for the possibility of redeveloping rain on Wednesday.

Fronts are areas where wind is blowing from a different direction than the winds in the area the front is moving into, therefore these airmasses bump into each other. Since the air cant go into the ground, it has no choice but to be forced upwards. Rising, warm moist air, cools and condenses into clouds and if they build high enough, can eventually produce rain.

Those light southerly winds continue over night tonight into Wednesday which in turn increases high temperatures Wednesday to near 70 degrees.

That frontal boundary will still be hanging around Thursday which gives us at least a chance of some developing showers before the next system moves in Thursday night, increasing our chances of rain.

As that low tracks on a west to east path into Illinois Friday morning, rain will continue to track over southern Wisconsin through Friday evening with high pressure then moving in behind the low.

Temperatures will cool for the weekend, but remain seasonable with highs in the upper 50s to low 60s Saturday and then low to mid 60s Sunday.

Conditions remain dry until the next system in line moves in Monday morning, bringing in more rain.
