The Storm Continues…Forecast Snow Totals

***Watch WISN 12 News at 5, 6, & 10pm Saturday for updates on the snowy conditions!***

The weekend is here, but so is more snow!  This storm system that is producing snow across Southeast Wisconsin has now been affecting our weather for the past 5 days!  Finally on Sunday the snow will come to an end and the system will head east.

Until then we have more accumulating snow in the forecast which we have been discussing here in the blog and on 12 News.  A Winter Weather Advisory is in effect for the eastern and southeastern parts of our viewing area.  This includes Sheboygan, Milwaukee, Racine, Lake Geneva, and Kenosha just to name a few cities.  Most areas will see 2-4″ of snow, but due to lake enhancement near Lake Michigan totals near the lake could be in the 4-6″ range in some backyards.

Here is the radar image just after 2pm on Saturday.  I labeled the area in northeast Illinois currently seeing the heaviest snow.  This band will try to rotate into extreme southeast Wisconsin and then move close to the lake shore.  Areas west of Waukesha County not in the advisory will see less the 2″ of snow, and in some cases under 1″ especially near Madison.

Why are we seeing some lake effect adding to our totals? Let’s check out the surface map.  As of about 1:45pm there was a surface low in southwest Wisconsin marked by the ‘L’ on the map below.  Wind circulate counterclockwise around low pressure in the northern hemisphere.  That means the winds around Milwaukee are out of a southeast direction.  This is pushing the cold air tempeatures over the water which is around 40-42 degrees.  The air temperature and water temperature is far enough a part for a a little lake effect to enhance the snow already associated with the low pressure area to our west.  This means locations close to Lake Michigan will see the highest snow totals this go around.  If you are wondering the site marked ‘MKE’ on the map below is Mitchell Airport.  It was reporting 1/2 mile visibility and moderate snow(3 *’s) around 1:45pm. 

By this evening the winds will begin to shift to the south and then more southwest.  This will cut off the lake effect, and as the low meanders by, our snow should taper off to flurries.

Thank you for stopping by the Weather Watch 12 blog.  Please post your snow totals in the comments section and I will use them on one of our 12 News shows this evening!  If you are venturing out tonight, please use caution on the roadways and make sure to watch 12 News for the latest on the snow.

  1. This has to be a historic storm the way the cold air wrapped all the way around and came from the south-southeast. I have never seen that before. I can only imagine what it was like on the west side of the low. I know it would mean a lot of misery for a lot of people but I would like to see a blizzard again. It has been a long time since we had hard blowing snow here. The shapes left after the storm are always interesting and I like the feeling of being safe and warm in my home while the storm rages outside. A little crazy I guess. Thanks for your blog. It is the best I found today.

    • Tom,

      Thanks for stopping by and sharing your thoughts. I guess a blizzard is the winter version of a tornado, minus the really bad destruction. Although snow storms and blizzards impact a much larger area. Each obviously has its down side, but very fascinating to observe.

      My former area, Kansas City was in the blizzard and just as you mentioned some of the drifts created some very unique sights after the storm eased up.

      Thanks for stopping by and enjoy the snow today!

  2. I want another blizzard here in KC, it is AWEsome. The power goes out make you want to go outside during it, just like u see in the movies.

    • Andrew,

      Sounds like it was fun for you, but others thought it was miserable. At least it is now gone, but not fogotten.

  3. I just thought of something I need to move up in your neck of the woods I could be a quality control inspector for the breweries I was wondering is almost like a cuttoff low. And explain in detail why it is or not thanks. I was just curious.

    • Jason,

      You could apply for that job at the Miller plant:) This storm is pretty much cut-off from the main flow right now. If you believe in the LRC, and this storm comes back in the Spring it could be a classic cut off low. Let’s keep this in mind for April and June!

  4. Hi Jeremy,

    Welcome to Milwaukee! You’re a great meteorologist and we’re glad to have the privilege of watching you on WISN!

    • Dan,

      Thanks for the welcome! I’m new to WISN, but not to Wisconsin. I graduated from UW-Madison and forecasted weather in southern Wisconsin for 5 years. Thanks for stopping by the blog!

      Jeremy
