Today’s Spring 2021 weather review shows that the season represented a significant departure from other recent years in that it was drier than average. In fact, there were fewer measurable precipitation days during the season than any other spring since 1879. Snowfall was also well below normal aside from a rare late April event. Temperatures swung wildly, with highs generally well above normal and lows slightly below normal.

What are the worst heat waves in history? The climate in Ohio is gradually getting warmer and wetter, and persistent record heat is becoming ever more common, but do recent heatwaves compare to those of the past? Let’s find out.
To find out what the worst heatwaves were, I looked at average temperatures for different consecutive time periods- 2 days, 3 days, 7 days, 10 days, 14 days and 30 days. Unsurprisingly, some historically hot summers popped up, particularly from the 1930s.

The heat waves in 1934 and 1936 dominated for high temperatures, and for the most part, nothing before or since has really come close. 1881, 1901, 1918, 1955 and 2012, among others, all make appearances.
Now that we’ve see the worst periods for high temperature, let’s look at the worst for the mean temperature, which is the average between the high and low. Because this measurement includes the low temperatures, it could be considered the definitive look at what the absolute hottest heat waves in history really were.

1934 and 1936 still dominate, but other years show up more often as well. Only 2012 shows up with anything in the last 60 years, though. That year also saw one of the worst wind events in Ohio history, partially fueled by the heat of that summer: North American Derecho of 2012
Finally, let’s look at periods that featured consecutive days with highs of 90 degrees or higher. What are the longest?

The NOAA temperature outlook for winter 2020-2021.
The Winter 2020-2021 Review is the latest edition in the series. Overall, December and February brought some of the worst winter weather Columbus had seen in several years. Meanwhile, January and March were unusually quiet. Temperatures through January were fairly to slightly above average, while February was well below normal. March and April provided little winter weather, and March had no snowfall whatsoever.
Let’s break the winter down.
December-February Only Average High: 37.8 42nd Coldest Average Low: 25.1 34th Warmest Mean: 31.4 42nd Warmest Precipitation: 6.72″ 38th Driest Snowfall: 24.7″ 31st Snowiest Average Daily Snow Depth: 1.0″ 15th Highest Largest Snowstorm: 5″ on 1/30-2/1/2021.

Much to the potential annoyance of many, parts of Ohio- including Columbus are predicted to see a late-season snowfall Tuesday night into Wednesday morning. As late as it may seem, Columbus has seen even later season snowfalls since 1878. Though rare, these events do happen, and have sometimes been significant.
The US weather map on the morning of May 21, 1883.
The absolute latest measurable snow occurred on May 21st, 1883, when 0.4″ fell. The amount was not impactful, but the date certainly was. People are normally thinking about summer by then, but instead got a nasty taste of winter. The present-day I-71 corridor in the state generally had had an inch or less- Cincinnati had upwards of 2″, with 3″ near Hamilton. However, areas just to the north and west were hammered with the heaviest May snow ever recorded.
An excerpt from the book “Thunder in the Heartland” by Thomas W. Schmidlin: “A drizzling rain on Monday morning, 21 May, turned to snow at 9AM, and the air was filled with large, damp flakes all day. The Sidney Journal reported that ‘though it thawed, it lay six inches deep on Tuesday morning.’ Considering that much of the snow melted as it fell, a total of fifteen to twenty inches was estimated for Sidney. Snow depts of ten inches were measured on the north side of buildings at Houston in Shelby County.”
The Columbus Dispatch reported that snow fell in every major city from Lancaster north and west. Crops and trees were damaged by the heavy, wet snow across Western Ohio during the event. Temperatures at most locations were at or above freezing during the snow, so it did not stick around long after. Just 3 days later, it hit 80 degrees in Columbus.
Dates of Measurable Snowfalls After April 15th 1. May 21, 1883: 0.4″ 2. May 9, 1923: 0.3″ 3. May 7, 1989: 0.8″ 4. April 30, 1908: 2.4″ 5. April 24, 2005: 3.0″ 6. April 22, 1893: 0.8″ 6. April 22, 1901: 0.1″ 7. April 21, 1934: 0.4″ 7. April 21, 1936: 0.2″ 7. April 21, 1953: 0.2″ 8. April 20, 1910: 2.4″ 8. April 20, 1962: 0.1″ 9. April 19, 1887: 0.1″ 9. April 19, 1907: 0.4″ 9. April 19, 1969: 0.5″ 9. April 19, 2019: 0.3″ 10. April 18, 1983: 0.1″ 10. April 18, 1984: 0.3″ 11. April 17, 1961: 1.0″ 11. April 17, 2001: 0.6″ 12. April 16, 1935: 0.4″ 12. April 16, 1956: 0.3″ 12. April 16, 1996: 0.1″
Trace amounts have occurred many additional times after April 15th, including into early May. Measurable snow, however, has only occurred 23 times after April 15th since 1878. So snow after that date has occurred roughly once out of every 6.2 years. That rate is not going to be matched this time, as measurable snow fell on April 19th last year. Snow is predicted sometime tomorrow night, the 20th. If it ends up being measurable, it would fall into the tie of 8th latest such ever recorded.
The March, 2008 Columbus snowstorm was a historic and memorable event that will likely not be surpassed for a very long time, if ever. More than one week prior to the Blizzard of 2008, models had been hinting at a significant storm somewhere in the eastern US. Initially, models took the storm up the East Coast, but as the storm neared, models moved it further and further west and settled upon a track just west/just along the spine of the Appalachians. The track waffled for days, but never strayed far from the Appalachian track. Because the storm was originating near the Gulf of Mexico, models were showing the storm pulling vast amounts of moisture north into cold air over the Ohio Valley. Simply put, the track and conditions were being forecast to be perfect for a significant Ohio snowstorm.
Local forecasters, however, weren’t buying it… at least not at first. Four days before the storm, neither the NWS nor the television forecasters were calling for a significant event. The winter of 2007-08 had brought several storm busts, and none of them seemed ready to buy into another one. So right up to 24-36 hours before the event began, most forecasters were calling for 6″ maximum north and west of the I-71 corridor with a mix along the corridor and mostly rain to the south and east.
At 4AM on March 6th, the National Weather Service issued a Winter Storm Watch for parts of Ohio, including Central Ohio. The Watch called for 5″-10″ northwest of I-71, with lesser amounts along 71 due to a predicted changeover to sleet and freezing rain and far less just to the south and east.

…WINTER STORM WATCH IN EFFECT FROM FRIDAY MORNING THROUGH SATURDAY EVENING…
THE NATIONAL WEATHER SERVICE IN WILMINGTON HAS ISSUED A WINTER STORM WATCH…WHICH IS IN EFFECT FROM FRIDAY MORNING THROUGH SATURDAY EVENING.
LOW PRESSURE WILL DEVELOP IN THE LOWER MISSISSIPPI VALLEY LATE TONIGHT AND LIFT NORTHEAST INTO THE TENNESSEE AND OHIO VALLEYS FRIDAY AND SATURDAY. SNOW WILL OVERSPREAD THE REGION FROM THE SOUTH ON FRIDAY MORNING. THE SNOW WILL LIKELY MIX WITH OR CHANGE OVER TO SLEET AND FREEZING RAIN FRIDAY AFTERNOON AND EVENING ALONG AND TO THE EAST OF THE INTERSTATE 71 CORRIDOR FROM CINCINNATI TO COLUMBUS. AS COLDER AIR FILTERS BACK INTO THE REGION…ANY MIXED PRECIPITATION WILL CHANGE BACK TO ALL SNOW FRIDAY NIGHT AND CONTINUE INTO SATURDAY. MINOR ICE ACCUMULATIONS ON TREES AND POWER LINES WILL BE POSSIBLE. PRECIPITATION WILL REMAIN MOSTLY ALL SNOW WEST OF THE INTERSTATE 71 CORRIDOR. 5 TO 10 INCHES OF SNOW WILL BE POSSIBLE IN THESE AREAS…WITH LIGHTER AMOUNTS FURTHER EAST WHERE SNOW MIXES WITH FREEZING RAIN AND SLEET.
THE EXACT PATH AND STRENGTH OF THE SYSTEM IS STILL IN QUESTION. IF THE SYSTEM MOVES FARTHER WEST MORE WARM AIR WILL LIFT INTO THE REGION…CAUSING LOWER SNOWFALL TOTALS AND MORE MIXED PRECIPITATION. IF THE SYSTEM SLIDES FARTHER EAST…LESS MIXED PRECIPITATION WOULD OCCUR AND SNOWFALL TOTALS WOULD BE HIGHER.
The Watch above did acknowledge that less mix could lead to higher totals, but nothing to the degree that would eventually fall. By later on the afternoon of the 6th, Watch totals did begin to creep up somewhat to 6″-10″ for the I-71 corridor, but the forecast still called for significant icing.
A Winter Storm Warning was finally issued at 4:30AM on March 7th, just hours before the snow would begin to fall.

…WINTER STORM WARNING IN EFFECT FROM NOON TODAY TO 4 PM EST SATURDAY…
THE NATIONAL WEATHER SERVICE IN WILMINGTON HAS ISSUED A WINTER STORM WARNING…WHICH IS IN EFFECT FROM NOON TODAY TO 4 PM EST SATURDAY.
LIGHT SNOW WILL OVERSPREAD THE REGION LATE THIS MORNING. THE SNOW WILL BECOME HEAVIER THIS AFTERNOON…AND LAST THROUGH SATURDAY AFTERNOON. FIVE TO SEVEN INCHES OF SNOW IS EXPECTED TONIGHT…WITH AN ADDITIONAL FIVE TO SEVEN INCHES FALLING SATURDAY MORNING. SNOW WILL TAPER OFF AND END SATURDAY AFTERNOON.

BY LATE SATURDAY AFTERNOON…A FOOT OR MORE OF SNOW IS EXPECTED WITH DRIFTS OVER TWO FEET.
The Warning abandoned all mention of mixing as models came in colder, and totals were now predicted to be at least a foot in the Columbus area with near blizzard conditions.
My personal account of the storm:
On Thursday, March 6th, I worked a 12-hour day at my store. Customers were talking about forecasts of 4-8″, which in central Ohio is significant in and of itself. We typically get one or two 6″ storms, but rarely up to 8″ and almost never more than that. In fact, in all of Columbus history, there have been less than a dozen snow events that broke double digits. Still, in the talking there were whispers that the storm would be more significant. By Thursday night when I arrived home, I discovered the radar was lit up over the South with a growing area of precipitation heading north. Temperatures had already cooled into the low 30s as a cold front had moved through during the day. Forecasts had changed late in the afternoon, and there were many calls of 6-10″ along I-71 by Sunday.
Friday, March 7th was my day off, and I woke up before 8am in the excitement and inticipation of the impending snow. The radar was showing returns north of the Ohio River then and it was already snowing in Cincinnati. Finally, at 9:05am, flurries began to fall and quickly intensified to a steady, windblown snow. A 9:30, I left the house to go to the store. By the time I reached it, the snow had turned heavy and was accumulating quickly. Visibility had dropped to a 1/4 mile at times and many roads were already snowcovered by the time I reached home.
The snow continued throughout the day and forecasts kept changing. At 3:30PM, the Winter Storm Warning was upgraded to a Blizzard Warning for the entire area until 4PM the following day.

Meanwhile, the snow continued into the evening and overnight hours of the 7th. Although it did lighten somewhat towards midnight, it never completely stopped. By midnight, in any case, 5-7″ had fallen throughout Columbus and central Ohio, which set a daily record.
Saturday, March 8th dawned very wintry. By dawn, no less than 10″ was on the ground and the snow was continuing to fall heavily. Winds were generally sustained near 20mph in the morning and increased during the late morning/early afternoon. Heavy snow and winds combined to create total whiteout conditions at times, and every county along I-71 from Cincinnati to Cleveland went under a level 2 or level 3 snow emergency.
At 11am, I went for a walk in the snow. It was still falling heavily and roads were nearly impassable with deep snow. Cars in some cases were buried in snow.
By 2pm, a break in the snowfall came as the low moved to the east of Ohio. When it moved into New York, wraparound snow moved back into the area for 3-4 more hours before ending by 6:30pm Saturday afternoon. The sun even poked through the clouds as it set, producing a very picturesque and beautiful winter scene. A fitting end to the day.
All in all, it was a record setting snowstorm all across the state. Columbus’ 20.5″ of snowfall, including 15.5″ on Saturday alone, was the greatest snowstorm of all time for the city. It also established the greatest 24-hour snowfall and the greatest snow depth ever recorded for any month at 18″. No part of the state was spared, as all major cities except Toledo had 10″ or more. Drifts of 5-7 feet deep were reported in many areas.
Aside from Columbus’ record, here were some other totals across Ohio. Cincinnati: 10.7″ Dayton: 15.4″ Lancaster: 17.0″ Akron: 17.1″ Marysville: 15.5″ Chillicothe: 14.0″ Westerville: 15.0″ Grove City: 11.3″ London: 17.0″ Cleveland: 14.8″ Delaware: 13.5″ Springfield: 15.0″ Belletontaine: 11.0″ Circleville: 13.5″
The storm also brought some areas of the state to record territory in total seasonal snowfall.
Incidentally, 30 years and 2 months prior, the Great Blizzard of 1978 struck. It is somewhat of note that Ohio’s greatest blizzards on record occurred during the “8” years. 1918, 1978, and now 2008.
