More Cold…and Snow!

***Watch WISN 12 News at 5, 6, & 10pm for the latest on our next chance of snow!***

***Wednesday Morning Update***

A quick update before a new blog comes out this afternoon. Winter Storm Warnings will go into effect on Thursday for Ozaukee, Milwaukee, Waukesha, Washington, Racine, Kenosha, and Walworth counties. Snow will be heavy at times and winds will increase producing blowing and drifting snow. Most roads will be snow covered and slippery. Snow totals will be greatest from Milwaukee south to Kenosha, 6″ or more will fall due to lake enhancement. Totals will be less the farther west and northwest you move inland. Check back this afternoon for a complete update with updated forecast snow totals and stay tuned to Weather Watch 12 for the very latest on this winter storm!

Thank you for stopping by the Weather Watch 12 blog. If you are new to the blog welcome, and if you are a regular thank you for bookmarking our site! In this blog we’ll talk about a couple the chill ahead and also our next chance of accumulating snow.

Let’s start with right now. On Monday a cold front pushed through the region and turned our winds to the northwest in Southeast Wisconsin. If you were outside at all on Monday afternoon I’m sure you noticed the winds which gusted to around 30mph! The winds will ease up heading into Tuesday morning which is the good news, but mostly clear skies and lighter winds mean one of the coldest nights across the region in a couple of weeks. Lows should drop to the single digits inland, and around 10 by the lake shore.

Here are the forecast temperatures around 6am on Tuesday from the NAM computer model. The dark blue over much of Southeast Wisconsin is temperatures of 5 to 10 degrees above zero.

After the cold start on Tuesday temperatures will only warm into the upper teens to around 20 inland, and maybe low 20s near the lake. It will be a cold day.

The focus by Wednesday quickly shifts to our next storm. This storm should be fairly weak, but it should represent our next chance of accumulating snow across the region. Let’s look at the timing. On Wednesday we will see thickening clouds during the day, and by late afternoon some of the light snow will near Southeast Wisconsin. Right now it looks like most of the light snow will occur from Wednesday afternoon to early Thursday. A very preliminary total for this is 1-3″. We’ll continue to examine the latest data and pass along updated forecast on WISN 12 News.

To give you and idea of the snow area for this storm let’s check out the 12Z GFS forecast for TOTAL precipitation from 6am Wednesday to 6am Thursday. The darker green shape over Southeast Wisconsin represent 0.10″ to 0.25″ of liquid precipitation…or about 1-3″ of snow.

After the little dose of snow moves by, the focus will shift to a push of arctic air. To learn more about this make sure to check out the blog entry that I did right below this one. The coldest days should be on Friday and Saturday.

On Tuesday I will try to do a blog entry outlining my thoughts for all of January. This forecast will be based on the LRC, which is a weather pattern theory that aides in long range weather forecasting.

Have a great day and thank you for trusting Weather Watch 12 as your #1 source for weather information!

  1. I wouldn’t be surprised if some areas hit 4-5 inches. As cold as it is, I can see liquid/snow ratios up to 15:1

    Is it Spring yet? LOL

    • Yeah…not out of the question. 1-3″ is the early estimate for Milwaukee. The NAM is a little wetter than GFS. Our in house model the RPM isn’t quite as robust as the NAM. So 1-3″ looks good right now.

  2. 83 more days until Spring. ^.^ Or maybe it’s 82. I don’t know. Either way, we’re that much closer!

    This past year’s temperatures were nice, since it wasn’t blazing hot, but it could stand to be just a little warmer, for the upcoming year…

    • I’m ready for Spring too! But the reality is we still have 3 months of winter left around these parts. Thanks for stopping by to say hi!
