MADISON (WKOW) -- A complicated weather system is approaching our region and will cross through southern Wisconsin Monday and Tuesday. Pure rain will expand across our region by mid-late morning on Monday.
Colder air will infiltrate from the north, allowing for freezing rain to develop in our northern areas during the afternoon, then central sections in the evening and overnight. As of now there is a chance for tough travel in the Madison area later tonight, mainly after the evening commute. Meanwhile, significant travel delays are expected for northern areas. Farther south, heavy rain and even some rumbles of thunder are possible through the PM and overnight hours.
Pure rain will take back over during Tuesday morning as warmer air pushes into the region. Then, the sweeping cold front will move through during the afternoon allowing for one last push of rain mixed with freezing rain.
Up to a 1/2" of ice is possible for far N&NW spots where significant glazing is expected making for dangerous travel. Power outages are even possible.
Farther south, up to 2" of rain will fall causing flooding concerns for low-lying areas and along waterways. Don't drive through water-covered roads since you won't know how deep it is!
Stay tuned for future updates as a 1-2° temperature difference could change the precipitation type, especially for central sections, including the Madison area.
