Winter weather advisory: Rain to switch to snow Wednesday

The month of February is ending with some crazy weather, and the month of March will start with a variety of weather as well.

Thunderstorms Tuesday morning tracked from northern Dane County to near Columbus and Beaver Dam. Even though temperatures were in the 40s, the atmosphere was unstable enough to support strong thunderstorms that produced marble-sized hail that covered the ground in some areas.

A warm front this afternoon made it as far north as southern Dane County. While areas north of the front stayed cloudy and foggy with temperatures in the 40s, communities toward the Illinois state line saw their temperatures soar into the lower 60s.

Winter weather advisory: Rain to switch to snow WednesdayIn the warmer air to the south, a tornado watch has been issued for northern Illinois until 10 p.m. In the cooler air to the north, a dense fog advisory was issued until midnight for areas north of Dane County where visibility dropped to near zero.

As a low pressure system tracks near the Illinois state line Tuesday evening, showers and a few thunderstorms are possible. As the system moves to the east, winds will switch to the north and colder weather will arrive later Tuesday night. Rain will mix with snow by early Wednesday morning as temperatures fall to the mid-30s.

Precipitation on Wednesday will change to snow early in the day before tapering to flurries by late afternoon or evening. Snowfall accumulations of 1 to 4 inches are expected, with the heaviest amounts over east-central Wisconsin toward the Fox Valley. Another weaker weather system will move through on Thursday, bringing light snow that may bring another inch of accumulation.

After a cold day on Friday, a warm front will move through Wisconsin on Friday night. Temperatures will jump right back up to mild levels, with high temperatures in the lower 50s on Saturday, and in the middle to upper 50s on Sunday.

Another storm system on Monday will bring showers and thunderstorms, followed by colder weather for Tuesday.
