Madison dodged a massive snowstorm that dumped two feet of snow in Green Bay over the weekend, but the combination of snow, freezing rain, sleet and rain did make for treacherous driving.

Light snow carrying over into Monday morning made for some slick patches again, with the state highway travel map showing slippery stretches all over the Madison area except for roads to the south.

The wicked winter weather is delaying the start of the school day at over three dozen school districts and schools Monday morning, mostly in southwest Wisconsin and in counties north of Dane County.

Following a few snow showers that could total about a half-inch of snow in Madison on Monday, Tuesday's forecast looks good, with sun and a high around 40, but another round of mixed precipitation, including freezing rain, is expected on Wednesday.

The National Weather Service said Wednesday could start out with freezing rain before 9 a.m., then freezing rain and sleet for an hour, then rain after that, and snow later at night.

New ice accumulation of less than a tenth of an inch is forecast, and less than a half-inch of snow is expected.

27 Storm Track meteorologist Guy Brown said a gradual warm up for the Madison area starts Thursday, with highs of 46 on Thursday, 54 on Friday, 55 on Saturday, 57 on Sunday and 60 on Monday.

Skies should be partly to mostly sunny Thursday through next Monday, Brown said.

Sunday's high in Madison was 29, 28 degrees below normal and 58 degrees below the record high of 87 for April 15, set in 2002.

The high of 29 set a new record for the coldest high temperature in Madison on April 15, breaking the old mark of 32 set in 1935.

The low on Sunday was 24, 12 degrees below normal and 6 degrees above the record low of 18 for the date, set in 1928 and tied in 2014.

0.16 of an inch of precipitation fell at the airport on Sunday, bringing the April total up to 1.34 inches, 0.32 inches below normal.

The record precipitation total on April 15 was 1.51 inches in 1998.

For the meteorological spring (March through May), Madison has received 2.08 inches of precipitation (rain and melted snow), 1.78 inches below normal.

Since Jan. 1, Madison has received 6.26 inches of precipitation, 0.28 inches below normal.

1.7 inches of snow fell at the airport on Sunday, bringing the April total up to 6.0 inches, 4.2 inches above normal.

That's more snow than what fell in December and just below what fell in March.

The record snowfall on April 15 was 4.5 inches in 1923.

For spring, Madison has received 9.4 inches of snow, 0.6 inches above normal, and 36.9 inches for the snow season (July to June), 13.0 inches below normal.
