Winter 2018-2019 Statistics




I get a lot of requests and searches for weather information on this site. Weather pages are actually some of the most popular. So I created a new page specifically focusing on the current winter season. It will have up-to-date stats dealing with snowfall, temperature, etc. This new page is here: Winter 2018-2019

The Biggest Snowstorms of All Time





Near blizzard conditions in Columbus just before 1am on 1/20/2019.

In light of yesterday’s strange storm that challenged local forecasters, I thought it might be time to look at Columbus’ biggest snow events since records began in 1878.

Ohio Had a Very Wet 2018




If your yard has been a swampy no man’s land all year, there’s a reason for it. 2018 was one of the wettest years ever across the state. In some cities, almost every month featured above normal precipitation. Let’s take a look across the state to see how places fared in this extraordinarily soggy period.


Here were the final 2018 totals in major Ohio cities and how they rank since their records began.

Cincinnati: 55.90″ 3rd wettest since 1871.
Columbus: 55.18″ 1st wettest since 1878.
Cleveland: 51.47″ 4th wettest since 1871.
Youngstown: 50.97″ 2nd wettest since 1896.
Dayton: 48.99″ 10th wettest since 1893.
Akron: 48.46″ 5th wettest since 1896.
Toledo: 38.01″ 22nd wettest since 1871.

In big cities in Ohio, only Toledo managed to avoid having a top 10 wettest year. Columbus had its wettest on record, beating the previous record of 54.96″ set just a few years ago in 2011.

Locally in the Columbus metro, here were some other totals.
Newark: 56.01″
Marysville: 51.12″
Lancaster: 50.51″
Circleville: 46.66″
OSU Campus: 46.66″

Biggest Individual Precipitation Day and Rank
Cincinnati: 5.02″ on 8/16/2018, 2nd highest since 1871.
Youngstown: 3.50″ on 9/9/2018, 11th highest since 1896.
Dayton: 2.88″ on 4/3/2018, 24th highest since 1893.
Akron: 2.50″ on 9/9/2018, unranked.
Cleveland: 2.12″ on 11/1/2018, unranked.
Columbus: 2.06″ on 4/15/2018, unranked.
Toledo: 1.62″ on 3/1/2018, unranked.

Cincinnati had 2 days in the top 10, but most other cities had just constant rain rather than exceptionally high individual totals.

Total 2018 Measurable Precipitation Days and Rank
Youngstown: 191 1st most since 1896.
Akron: 180 1st most since 1896.
Cleveland: 177 8th most since 1871.
Columbus: 162 6th most since 1878.
Cincinnati: 151 7th most since 1871.
Dayton: 148 10th most since 1893.
Toledo: 142 16th most since 1871.

3 cities saw more than half their days with measurable precipitation. Columbus came in at just under 50%. This also had the unfortunate result of making most of the year feel unusually gloomy. Traditionally sunny months in the summer and fall were much cloudier than normal.

Total 2018 1″+ Precipitation Days and Rank
Columbus: 15 1st most since 1878.
Cleveland: 13 2nd most since 1871.
Cincinnati: 12 7th most since 1871.
Dayton: 11 6th most since 1893.
Akron: 10 5th most since 1896.
Toledo: 7 7th most since 1871.
Youngstown: 5 9th most since 1896.

Columbus had the most 1″ days of any year on record, and even beat every other major Ohio city.

Wettest 2018 Months
Cincinnati: 8.21″ in August
Youngstown: 7.91″ in September
Akron: 7.26″ in September
Dayton: 6.72″ in September
Columbus: 6.71″ in June
Cleveland: 6.68″ in July
Toledo: 5.91″ in May

No cities saw any of their months be even close to the wettest ever. There were not really any events with heavy flooding, either, except in February in Cincinnati, when the Ohio River reached the highest since the 1997 flood. There was also some scattered flooding from some tropical system remnants that passed through, particularly in September, but for the most part, it was just constantly wet from beginning to end in most places.

Cincinnati flooding in February, 2018.

One might ask if 2018 was merely a blip or part of a long-term trend in the state. Climate scientists have actually looked at this, and the state has indeed been getting both warmer and wetter over the last century or so, but the pace of both the warming and the increase in precipitation has been much faster since the 1970s. Many of the Ohio’s wettest years on record have occurred since 1990.

The Week in Review #2

So last week, the FBI finally released the full crime numbers for 2017 for all cities. How did Columbus fare? Well, it was a decidedly mixed bag. Total murders were their highest ever, at 143, but the rate fell quite short of the record set back in 1991. So far for 2018, murder is behind 2017’s rate by about 22%, so it’s a good improvement, but still not even close to where it should be.

Other violent crime figures 2016 to 2017
-Rape continued its multi-year rise in the city, reaching 919 incidents. This was a 6% increase over 2016.
-Assaults were up 4% over 2016, but in the context of still being one of the lowest totals in the past 30 years.
-Robberies were down almost 8.5% over 2016.
-Despite the rises in most types of violent crime, the drop in robberies meant overall violent crime dropped by about 0.5%.
Property crime figures 2016 to 2017
-Burglaries were down more than 8%.
-Larceny thefts were down about 2.9%
-Motor vehicle thefts were up 17.6%, so not a good trend, but still less than half the rate it was 15-20 years ago.
-Overall property crime was down about 2% versus 2016.

And if you think this year’s been particularly wet, you are right! Through October 1st, Columbus is having its 3rd wettest year on record. Only 1882 and 1890 are ahead of 2018 at this point, and by barely 1″. 2018 at this point is running almost 14″ above normal.
Top 10 Wettest Years Through October 1st
1. 1882: 44.55″
2. 1890: 43.56″
3. 2018: 43.31″
4. 1979: 42.17″
5. 2003: 41.58″
6. 2011: 41.12″
7. 1990: 39.10″
8. 1949: 38.54″
9. 2004: 38.46″
10. 1996: 37.46″
It is surprising how many recent years are on this list. Still with 3 months to go, the pattern could break, but it’s very unlikely that 2018 doesn’t end up in the top 10. Here are the top 10 wettest full years.
1. 2011: 54.96″
2. 1990: 53.16″
3. 1882: 51.30″
4. 1890: 50.73″
5. 2004: 49.27″
6. 1979: 49.17″
7. 2003: 49.03″
8. 1883: 48.88″
9. 1881: 46.99″
10. 2017: 46.61″

Guess it could always be worse.
