Back in 2011 I thought the raw 9/11 memories would gradually fade into the background of our national consciousness. At the twenty year mark, I was mistaken. 9/11 is like a cut on your arm that never heals completely. Pearl Harbor, Kennedy Assassination and perhaps the Challenger Disaster come to mind as the only tragic events in the past few generations with a similar level of national trauma. Its crazy to think that most people in their early 30s might not have solid memories of the events of that day in 2001 because they were in early grade school. All high school and college students and young adults have grown up in a post 9/11 world. They know nothing else.

Is Late Summer Heat Becoming More Common?

Where Does This Summer's Rainfall & Humidity Rank?
No big surprise here. Even after an almost 2 week rainfall break in late July/early August, this summer still ranks 2nd all-time through August 19!
The individual rainfall events have been significant. Here is the number of 1/2" inch rainfall days.

How Does This Summer's Rainfall Compare To Recent Years?
It goes without saying that most of Ohio is well above normal rainfall since June 1st this summer (2021) A large portion of northern Ohio has received 10-15" of rain since June 1 with some areas close to 20 inches! Actual rainfall numbers are highest in eastern Huron, southern Lorain and most of Medina Counties.
Images below show rainfall vs normal. (Note the legend numbers are different for each image. Zero contour is the same for each)
How about last summer 2020? Most of northern Ohio was well below normal--with the exception of portions of Portage, Geauga, Trumbull and Ashtabula counties.

BELOW NORMAL Summer Rainfall in Northern Ohio...Where?
It's hard to believe but there are spots in northern Ohio that are near/slightly below normal with rainfall since June 1st. When you look at the rainfall vs normal OVERALL across northern Ohio this summer the dark blue areas (2-6" above normal) stand out.
But when you zoom in closer, the "drier" areas become more visible. The counties below which have significant areas of below normal rainfall since June 1 (tan colors--see legend to the right) are CUYAHOGA, LAKE, ASHTABULA, ERIE, HOLMES & TUSCARAWAS. I want to reiterate that this doesn't mean these areas are dry and without rainfall. It means that the amount of rain is below normal not zero.

Has This Summer Rainfall Been Unprecedented Across Ohio?
On July 5th we took at look at the summer pattern thus far. Check it out if you haven't already.
Here are the updated rainfall totals VS normal broken down in three periods:
First period is June 1 to June 15
Shades of blue indicated rainfall 3/4" or more above normal. Tan colors indicated below normal rainfall.
Second period is from June 16 to June 30. Heaviest rainfall was from Medina county west to just south of Findlay.
Now the final period is from July 1 to July 11. Heaviest rain across the southern half of northern Ohio.
Finally the summer totals overall from June 1 to July 11.
Purple colors show 8" or more since June 1. Green colors show between 4-8".
Soil moisture has increased significantly over the last week
Our summer outlook issued in late April highlighted frequent rain/storms this summer with above normal rainfall.
Pattern looks to continue through the end of July!

What Summer Was The Most Humid?
First a brief tutorial on why we use dew point versus relative humidity:
It's more of an absolute measure which isn't relative to temperature. For example a relative humidity of 50% when the temperature is 95 degrees would feel incredibly tropical. An RH of 50% when the temperature is 55 degrees wouldn't feel nearly as humid. A dew point of 70 is super-tropical all the time. A dew point of 45 is comfortable regarding of temperature or time of year. This graphic illustrates this idea very well.
What's the most humid summer since 1950 in northern Ohio (Cleveland)? 1995
2018, 2010, 1987 and 1973 round out the top 5
I did some research on the years with the highest heat indices measured in hours in northern Ohio. You can read about it HERE (written in 2019)
There is an upward trend for more humid summers over the last few decades in northern Ohio.
