What began as a Winter Storm Watch has now been upgraded to a full Winter Storm Warning in Effect for Southeast Wisconsin.

Forecasters are calling for a significant, all-day snow event this Saturday, prompting an alert for the entire region.

Residents should prepare for a widespread accumulation of 6 to 10 inches of snow.

The first flakes are expected to arrive in the pre-dawn hours, with snowfall becoming steady and heavy as the day progresses.

Travel conditions are expected to become extremely dangerous as the storm reaches peak intensity Saturday afternoon.

Communities along Lake Michigan may experience a wetter, heavier snow due to warmer lake temperatures, impacting areas around Milwaukee.

However, the potential for powerful lake effect snow bands could lead to locally higher totals right along the shoreline.

Inland areas are more likely to see a lighter, fluffier snow accumulation by comparison.

Officials are strongly advising residents to avoid all non-essential travel on Saturday due to poor visibility and slick roads.

This marks the second major snowstorm of the season, and road crews will face a significant challenge keeping routes clear.

The snow is expected to taper off early Sunday, but slick spots will likely persist into the morning commute.
