WARM & WET, BUT THE MOST INACTIVE JUNE SEVERE WEATHER-WISE SINCE 1988

The warmer than normal June 2018 may have turned wet, but it was unusually inactive severe weather-wise.

Overall, it has been much warmer than normal since May around our area.  In fact, at the Purdue University Airport, June 4 was the FIRST below normal day (high + low / 2) since April 30!  That was actually our last freeze of the spring with 32 degrees for a morning low.  That is quite a feat to have that stretch with no below normal days!

In June, 16 of the 30 days were above normal with only 9 below.  Of those 9, most of them were barely below except on June 23.  That day saw the mean temperature 7 degrees below the daily mean, which is the greatest deviation below normal for a day since April 29 when it was 12 degrees below normal.

With us expecting the mean temperature to be near 11 degrees above normal tomorrow, June 2018 will wind being a slightly warmer than normal.

After a dry, warm to hot May, the dryness continued into very early June before coming to an abrupt halt with periods of abundant rainfall the remainder of the month, specifically centered around the 20th.

June totals ended up 120-180% of normal in a month that is typical pretty wet anyway. 


The wettest month of the year is normally June for areas south of U.S. 24.  Along & north of U.S. 24, July tends to be the wettest month.  For the viewing area as a whole May 30 to July 5 is the wettest time of year from south to north over the viewing area.

On June 7, a severe t'storm destroyed a small outbuilding & knocked some small trees down two miles southeast of Otterbein, while quarter-sized hail fell at Peru.  the morning of June 9, some tree limbs were blown down near Romney.

Two landspout-type funnel clouds were reported on the evening of June 22, one near Waynetown & the other near Chalmers.

In the past 45 years, only 1988, 1994, 1996 & 2003 were even close to 2018 for this lack of severe weather in a June.  All other years were much more active.  Relatively recently, only four reports of severe weather were documented in the viewing area in 2003 with two gusts of 58 mph in Fountain & Montgomery counties & two EF0 tornadoes in West Lafayette & Lafayette.  However,, July 2003 was extremely active with record rainfall & flooding with severe weather.

There were just four reports in June 1996, them all being wind.  This is also remarkable, as spring 1996 was very active & flooding occurred.

The rather dry, droughty June 1994 saw four reports of severe weather with four severe gusts in White County with substantail damage & a tornado in Fulton County.

Of course, in the torrid, dry June of 1988 there was a lack of organized t'storms.  Not a single report of severe weather was documented, making it the least active since at least 1973.  I plan to go back several more decades, however, to determine how such a lack of severe ranks in the grand scheme of things for June.
