It is certainly close, but it looks as though the storm that is hitting just to our south will stay there. Kenosha county is under a winter weather advisory, but I don’t think that is warranted. Light snow is possible right along the border, but I only expect about an inch of snow there. Only flurries in Waukesha and Milwaukee. Here is the RPM computer model at midnight tonight.
The heavy snow will stay across Northern Missouri, North-Central Illinois, and Northern Indiana. They could pick up 6-8″ tonight. This is the first big storm to miss us in quite a while.
The next storm does not look like it will miss us. Sunday night will bring a rapidly strengthening low pressure center, but at this point is looks wet and not white. There could be a substantial amount of rain, possibly over an inch, that could create some flooding problems. It will become very windy on Sunday and Monday. Here is the GFS model for midnight on Sunday night.
Note the blue zero degree line. This is very important along with the 540 line on the 500 mb chart. This is often the dividing line between rain and snow. Here is the 500mb chart from the GFS model for Sunday night.
Both the zero line and the 540 lines are well north of SE Wisconsin. If the low stays on this path we are looking at mainly a rain event. As the low passes by on Monday morning cold air will wrap in on strong westerly winds changing the rain to snow, but because this will be the back side of the low there will be less moisture. Only minor accumulations are expected at this point. The storm is still four days away so a lot can happen to the track. Obviously, if it moves south that could put us in a path for more snow. Stay tuned.
