Signs of Spring…Sort of

***Watch WISN 12 News today at 5, 6, & 10pm for the latest on rain & snow chances!***

Thank you for stopping by the Weather Watch 12 blog! The signs of Spring are beginning to appear all around us…sort of. March does signal many ‘milestones’ that are often associated with Spring…including the official start.

Let’s take a look at some dates of note this month as we inch closer to Spring. On Sunday, March 14 Daylight Saving Time begins. This is where we ‘Spring Forward’ and set clocks ahead one hour!

About a week later on Saturday, March 20 at 12:32 p.m. Spring officially begins! Hopefully by that time our temperatures will be well into the 40s or even 50…we can only hope.

Probably the biggest change we see during the month(in part due to the time change) is the amount of daylight that is gained. Here is a look at sunrise and sunset times from the 1st to the 31st of the month.

March 1

Sunrise: 6:28 a.m. Sunset: 5:41 p.m.

March 31

Sunrise: 6:36 a.m. Sunset 7:17 p.m.

Those are the tangible milestones during the month, now let’s check out the unpredictable…the weather. Most people are eagerly awaiting the first 40s in over a month! Those are still on the way beginning on Friday in most areas. The 40s should then stick around thru the weekend. As I mentioned yesterday…we’ll watch closely as a lake breeze may develop and keep temps slightly right near the lake. Still no huge warm-ups in the next week or so.

Also something we are keeping an eye on is a potential storm or next week. This storm at one time looked very wet for Southeast Wisconsin…then not quite as wet…and now today one model has the storm basically missing our entire area!

Below is the 12Z GFS forecast. The forecast is valid for next Tuesday around noon. This shows an area of low pressure well to our south over Mississippi and Alabama. If this is indeed where the low tracks we would see little to no precipitation. It would also mean cooler conditions for our area with highs likely stuck in the 30s for part of next week.

There is still lots of time for this storm to move around, but the general trend has been a track farther south and also a little weaker. We will continue to monitor the latest for next week and bring you the updates on WISN 12 News at 5, 6, & 10pm.

If you get a chance try out our comments section of the blog…just leave your thoughts or questions and we will be happy to respond! Thank you for making Weather Watch 12 your #1 source for weather information!

  1. Hey Jeremy, I just checked the 1800 version of the GFS model, it has the storm passing us to the south over Tennessee, and weaker then the earlier models did. Also it looks like the freezing line is further south then before. So your comments are correct. I am a weather geek now, I am awaiting the NAM model that will show this storm, starting this weekend.


    • Bryan,

      The models for the most part are keeping this to the south. This weekend I’ll show how this pattern directly relates to January…and why this time in the cycle we may miss the precip.! Thanks for reading.


  2. Jeremy,

    Even though I love winter, I am definately looking forward to the warm weather ahead! What’s your favorite weather season?


    PS: looks like there’s more than one Bryan now so I’ll change my name above to distinguish apart. Maybe Bryans’ love weather? lol

  3. Checked the 600 version of the GFS model for 3/4/10 still has the storm passing to our south through Tennesee.

    • Bryan,

      The 12Z GFS was even farther south. I’m guessing our chance of precip. may be pulled from the forecast soon. I won’t complain…I’m done with snow.


  4. I am done with snow as well. When looking at the 800 mb/temp map how can you tell where the freezing line is. I know tis is a bit ahead of things but in looking at the 246 hour forecast on the 12Z GFS there looks to be a fairly signifigant storm coming through Iowa with lots of precip. That might not be a very accurate prediction at this point

    • At 850mb usually the 0 Celcius line is a good indicator of the rain/snow line. The later we get in March though…sometimes we will need a colder 850mb temp to produce snow.
