Latest storm drops as much as 9 inches on Milwaukee area. More snow forecast for Wednesday

This latest round of snow gave us a little more than we expected as southeastern Wisconsin is waking up Monday to almost 10 inches of snow in some areas.

Sunday's all-day light snow turned to overnight lake-effect snow along Lake Michigan.

Early snow totals from the National Weather Service office in Sullivan included 9.5 inches in West Allis, 6.5 at Mitchell International, 8 in Pleasant Prairie, 4.6 in Oconomowoc, 7.5 in Racine and 6 in Jackson.

You'll want to get that cleared off the driveway because more is in the forecast overnight Tuesday into Wednesday, perhaps around 2 to 3 inches, plus some freezing rain or freezing drizzle.

The winter weather advisory for the lakeshore counties expires at 6 a.m.

The overnight lake snow proved to be a challenge for road crews. Interstates were slush covered for the morning drive and streets in downtown Milwaukee were covered by a heavy layer of snow.

Heavy bands of lake-effect snow boosted totals in some areas, said Mark Gehring, a National Weather Service meteorologist based in Sullivan.

"We think (lake-effect snow) is helping out the snow totals in southeastern Wisconsin, but it's hard to tell because you have a storm coming out of the southwest and the lake effect (snow) is curling underneath it," Gehring said at 5 p.m. Sunday.

Gehring is expecting the lake-effect snow bands blanketing northern Milwaukee County north to the city of Sheboygan to shift farther south into the city of Milwaukee down to Kenosha County later Sunday night into Monday morning.

"When it's all said and done, there will be 6- and 7-inch totals. This is a long-duration snow, which started (Sunday) morning and will go all night," Gehring said.

A low-pressure system moved out of the eastern Rockies through the Great Plains, hitting Nebraska, Kansas and Missouri on Saturday before slowly moving into Wisconsin. The reason it's been snowing almost all Sunday is because the storm system is so slow-moving, said Gehring.

That could mean flurries continuing throughout Monday morning, even though the bulk of the snow is expected to end by 6 a.m.

High temperatures Monday will be in the 20s most of Sunday night throughout Monday before dropping into single digits Monday night in the metro Milwaukee area.

The next chance for precipitation in southeastern Wisconsin is late Tuesday. Though it's a bit early to pinpoint exactly when snow will start to fall, it looks likely between 3 and 6 a.m. Wednesday.

"We are expecting mostly snow for that storm," Gehring said. "We do have chances of light freezing rain and freezing drizzle with this system. It will start as snow, but by late Wednesday morning it will become more of a mix of freezing rain and snow. It's going to get kind of messy."
