Looking Ahead To St. Patrick’s Day

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

Thank you for stopping by the Weather Watch 12 blog!  A new week is here and signs of Spring are finally beginning to show up.  You know we have turned a small corner when all the high temperatures in the 7 day forecast are in the 40s or 50s!

With quiet weather in the forecast to start the week, let’s look ahead to some weather that may lift spirits for St. Patrick’s Day.  While searching on the U-Local page of WISN.com today I found someone who is excited for the warmer weather and St. Patrick’s Day, Clyde the dog.

That’s a nice look Clyde!

By Thursday temperatures are expected to jump into the 50s.  The warmest reading so far in 2011 was 53 back on February 17, and I think Thursday’s high temp has a good chance of topping it.

Below are forecast temperatures from the GFS computer model.  This indicates 50 to 55 degrees over parts of southern Wisconsin at 7pm Thursday! 

St. Patrick's Day Temperatures

The reason for the warm push of air is our winds at the surface and aloft will switch to a southwest direction on Thursday.  This will transport or advect warmer temperatures from the Plains and Midwest.  Below is a 500mb forecast map at 1pm Thursday.  Notice that winds are out of the southwest from southern California all the way into the Great Lakes.

While Thursday looks warm, it also may be wet at times.  Rain showers are possible Thursday.  But since we are still several days away we’ll focus more on the precipitation in the coming days.  For now it is nice to see all daytime highs in the 40s and 50s and no snowflakes in the forecast.

If you have questions or thoughts, please post them to the comments section of the blog.  And watch WISN 12 News for the updates.

Have a great day!

  1. Jeremy, do you think the Signature Storm will give us mostly snow?

    • Bryan,

      With our average highs now in the 40s it is becoming more difficult to get an all snow storm. So while I don’t see mostly snow, I think some may be possible next week.

  2. Hi, Jeremy —

    Wanted to let you know I spotted another sign of spring in our area — the robins are back. I saw one yesterday morning — and I talked to a fellow at church who had seen four. So now we have the robins back — the geese and sandhill cranes flying overhead from south to north — and the hyacinths are starting to poke through in a flowerbed that’s up against the foundation of our house.

    But I’m still not going to put the snowblower away yet — not until after signature storm. If you were forecasting right now for that event — would you think severe wx in our area or more like the December event — rain to mix to snow? Ultimately, time will tell, right?

    Just wondering about your take on severe wx potential?

    • Don,

      I think there will be a severe wx component to the storm, but if I had to lean one way or the other I would hedge that it stays south. We’ll have to watch it closely though.

      Great to hear the robins are back. Spring can’t be too far away.

      Jeremy
