Hail Pictures & First Day of Fall

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

Thank you for stopping by the Weather Watch 12 Blog!  Today marks the beginning of a new weather journey for our area…Fall.  If you follow the blog, you know that I believe this is the time of year that a brand new never before seen weather pattern begins to set-up.  Once the new weather pattern forms, it will then repeat for about the next 9 months.

In the coming days and weeks we will analize the new pattern, which will lead up to the winter forecast!  Look for the long range winter forecast right here in the blog coming in November

To start, let’s take a look back to yesterday’s severe storms that hit parts of Walworth and Racine counties.  Hail reports were numerous, and storm reports that I saw put hail sizes in the neighborhood of dime to golf ball.

The picture below is courtesy of Karen Heine of Delavan.  This hail measured 1.0″ in diameter, about the size of a quarter.

The next picture is from the U-Local section of WISN.com  This picture shows several hailstones from about dime to nearly quarter sized.  These hailstones fell near Delavan.  Remember, you can always share your pictures by posting them to the U-Local section!  Any pictures posted may be used on WISN 12 News and right here in the blog.

With the storms behind us in the short term, let’s focus on Fall!  Fall begins today at 10:09 p.m.  The official name for the first day of Fall is the Autumnal Equinox.  Equinox is from the Latin for ‘equal night’.  While the days and nights are close to being equal on the first day of Fall, they are not.  Here is why…

During the equinox, the length of night and day across the world is nearly, but not entirely, equal. This is because the day is slightly longer in places that are further away from the equator, and because the sun takes longer to rise and set in these locations. Furthermore, the sun takes longer to rise and set farther from the equator because it does not set straight down – it moves in a horizontal direction.

Moreover, there is an atmospheric refraction that causes the sun’s disk to appear higher in the sky than it would if earth had no atmosphere. timeanddate.com has a more detailed explanation on this topic.

This is sort of complex, if you have questions just let me know.  On the first day of Fall, the sun’s direct rays pass over the equator, and begin to head over the southern hemisphere.

The Earth’s axis continues to tilt away from the sun, meaning our days continue to see less daylight, and our nights are longer.  This eventually sends us into winter! 

While Fall is here, another summery day is in store for Thursday.  Showers and t-storms will bookend a day with highs in the 80s.  Very slight chance of a strong storm or two on Thursday.  We’ll discuss the big change for Thursday more on WISN 12 News and also in Thursday’s blog! 

Have a great day and please leave a thought or question in the comments section of the blog!

  1. How much rain can we expect from Thursday’s storms in our area?

    • Raul,

      Parts of the area could see over 1 inch. A lot will depend on where the warm front sets up.
