19th tornado confirmed in April 8-9 Ohio valley outbreak

The National Weather Service confirmed a 15th tornado in last week’s outbreak, and they may not be done yet. The 15th tornado started in Colerain Township and peaked in Mt. Healthy, Ohio.

The 14th tornado hit Indian Hill. Information and photos regarding this tornado were provided to the National Weather Service by Arbor Doctor Ron Rothhaas.

15 tornadoes is a remarkable number and illustrates why we were sounding the alarm last week.

Meteorological Versus Astronomical Seasons. Spring is here!

Spring: March 1-May 31; Summer: June 1-August 31; Fall: September 1-November 30; Winter: December 1-February 28 (29)

You may have noticed that Arbor Doctor, meteorologists and climatologists define seasons differently from “regular” or astronomical spring, summer, fall, and winter. So, why do  meteorological and astronomical seasons begin and end at different times? Read more here>>>
