More Rain, Sleet, & Snow – Wednesday Storm

***Watch WISN 12 News for the latest weather information!***

Thank you for stopping by the Weather Watch 12 blog!  A wet and messy storm system will push across our area over the next 24 hours.  Rain, a wintry mix, and snow are all possible.

The best way to track the wintry mess is with our interactive radar, just click below.

While Milwaukee will see more rain than a mix or snow, some wintry weather is possible.  A majority of the snow and messy mix will stay in our northern counties where temperatures will be a touch cooler.  Below is a map showing the counties under a Winter Weather Advisory.  In our viewing area, this includes Dodge, Fond du Lac, and Sheboygan counties from 3am Wednesday thru 6pm.  Just click on this map or any in the blog to enlarge.

Winter Weather Advisory Wednesday

The precipitation will begin Tuesday Night, likely as rain near the Wisconsin and Illinois border.  As the precipitation runs into colder air north-northwest of Milwaukee the precipitation could be a mix or snow.  Even a period of rain is possible.

Rainy weather should dominate heading into Wednesday morning over areas from Waukesha to Port Washington and points south.  North of this line a mix of rain/sleet/snow is possible.  Here is the surface forecast map from the HPC at Noon on Wednesday.  The pink dashed line is the rain/snow line which is  very near that Waukesha to Port line. 

Surface Forecast Map Wednesday

As colder temperatures wrap into the story system on Wednesday, the rain and mix will change to snow from northwest to southeast.  Even in Milwaukee, Racine and Kenosha some snow is possible.

Most the snow that sticks, or covers the ground, will occur in the ‘northern’ areas.  Snow totals around Fond du Lac, Sheboygan, and Beaver Dam may be in the 2″-4″ range.  Totals will drop off from this range the farther south and southeast you travel.

This will be a wet system, but likely not wet enough to cause major flood problems…which is good news.  Certainly some creeks, streams, and rivers will rise, but most areas will see rain totals under 1.00″.

Below is the total precipitation forecast for our area.  This is from our high resolution computer model the RPM.  Most of southeast Wisconsin should be around 0.40″-0.80″.

RPM Precipitation Wednesday

Now if you are wondering how much of this will be snow, here is the RPM forecast.

RPM Snow Totals Wednesday

Keep in mind our snow forecast does differ a bit from the RPM, but the general trend of more snow to the north, and less to the south should hold true.

Any slight shift to the north or south may mean more or less snow.  Stay with WISN 12 and Weather Watch 12 for the latest!

Please post your snow and rain reports to the comments section of the blog or on Facebook at WeatherWatch 12!

Have a great day!

  3. Storm update: 7am

    Presently getting light to moderate at times mix of rain & snow. Not much in the way of snow accumulation. Rainfall gauge showing 0.55 inches. Not much in the way of wind right now, rain/snow seems to be ‘falling’ from a just east of north direction.

  4. We’ve been mostly snow here in Waukesha county. Estimation of 2-3″ seems likely. And it’s still snowing — I’ll give you a final report after the storm is over.

    • Thanks for the snow reports. I’ll get the blog updated this morning. Keep the snow reports coming!


  5. I liked Gary Lezak’s comment the other day about “until we learn to control the weather”, I know it was tongue and cheek but it would be nice to be able to control the weather so we can “schedule” when it percipitates, or make all the snow rain. Wishful thinking I know. But in some of the Star Trek books I read the Earth’s weather is controlled and it only rains at night.

    • Bryan,

      If we could control the weather I don’t think we would have had the February 1-2 blizzard:) And it would be in the 70s now.
