Snow Storm Weather Forecast: Southeast Wisconsin Braces for Hail Tonight, Then a Rain-to-Mix Turn by Morning
Southeast Wisconsin’s snow storm weather forecast is colliding with a very different immediate threat: showers and storms expected this evening with a large hail risk, followed by lingering precipitation overnight and a transition toward a mixed setup by Wednesday morning.
What’s driving tonight’s risk window in the Snow Storm Weather Forecast?
Showers and storms are expected to develop this evening, bringing a large hail threat. The most significant hail risk is concentrated between 5: 00 pm and 10: 00 pm ET, while scattered showers and storms may continue through the night.
Not all areas are expected to face the same level of severe weather. Most of tonight’s severe conditions are expected to remain south of the Illinois border, narrowing the zone where the strongest impacts are anticipated.
When does precipitation change over, and where could freezing rain show up?
Conditions are expected to shift toward a mix of precipitation by Wednesday morning. The changeover introduces the possibility of freezing rain far north, along with minor slushy snow accumulation in some locations. The overall expectation for Wednesday includes rain transitioning to a mix, with less than 1 inch of snow accumulation mainly in the northwest.
Forecast details for the near term also include:
Tonight: scattered showers and storms, low of 34, northeast wind 10–20 mph.
Wednesday: rain to mix, less than 1 inch snow accumulation mainly northwest, high of 34, northeast wind 10–20 mph.
How long does the active pattern last after the midweek mix?
The pattern is expected to remain active through the week. Another round of mixed precipitation is possible Thursday night, with yet another round possible again this weekend. Forecasters are watching the potential for a bigger winter snow/mix event for Sunday.
Thursday’s setup is described as mostly cloudy with snow or a mix likely at night and a high of 44. As this unfolds, the snow storm weather forecast for the region remains focused on timing shifts: hail-focused storms first, then lingering showers, then a rain-to-mix evolution by morning, and additional mixed rounds later in the week.
