Past Election Weather & Cold Air Ahead

***Watch WISN 12 News at 5, 6, & 10 p.m. for Milwaukee’s most accurate forecast!***

Thank you for stopping by the Weather Watch 12 Blog!  Election Day is here, at the end of this blog make sure to vote for how much snow you think will fall this winter in Milwaukee! 

The weather looks great today, so no excuses for not voting!  Early November is a time of year that anything is possible weatherwise!  I dug up some info on past weather conditions for Election Day in Milwaukee.  Here you go:

  • November 3, 2009   High: 46
  • November 4, 2008   High: 73
  • November 6, 2007   High: 43
  • November 7, 2006   High: 57
  • November 8, 2005   High: 42   Rainfall: 0.02″ 

Overall pretty quiet weather in early November over the past 5 years.  The average high for November 2 in Milwaukee is 53 degrees with an average low of 37.

Pretty amazing that just 2 years ago it was 73 on November 4th!

Our current seasonal weather is about to change in a big way.  A cold front will slide through on Wednesday, a few sprinkles or a brief shower could accompany the front.  The big change with the front will be a cold push of air behind it.

If, and this is a big if, any moisture is still around on Thursday, our 850mb temperatures would be cold enough to support flurries!  This is something we will monitor very closely over the next day or so.  The first snowflakes of the season always get people excited!

Below is a forecast surface map from the GFS computer model.  This map is valid late Thursday.  The forecast map also shows 850mb temperatures, those are the blue and orange lines.  The most important line for us is the 850mb 0 degree celcius line.  850mb is located about 2500 to 3000 feet above the Earth’s surface.  This line often indicates the rain/snow line.  And notice how far south this line is, it is located over Missouri and the Plains.  A good indicator that snow flurries are possible if any moisture is squeezed out.   

Now how cold will surface temperatures be on Thursday?  Right now it looks like highs will be in the low 40s in Milwaukee, with some upper 30s in western and northern counties.  Temperatures will fall back a few degrees by evening.  Below is a surface temperature forecast map for Thursday at 7 p.m.  Notice the mid to upper 30s over most of southeast Wisconsin.  

Any way you look at it we are slowly progressing toward winter.  There will be more ups along the way, but the decline of temperatures and more frequent pushes of cold air are a good sign that winter may be around the corner.  In honor of Election Day make sure to take our poll question below.  How much snow will fall in Milwaukee this winter?

Make sure to watch WISN 12 News for the latest election results and weather information!

Have a great day!

  1. I didn’t know which way to vote on your snowfall poll, the amount of snowfall I’d like to see or what will most likely happen. I wish it would be less than 25″, but common sense tells me it will probably fall in the 25-40″ or more. Doesn’t less snow mean colder temps? I guess it’s a toss-up.

    • Cliff,

      Generally more snow equals colder temperatures. Remember, snow on the ground reflects sunlight…very high albedo. Plus, having snow on the ground is like dropping ice cubes in a drink, the snow makes the air near the surface colder.
