The 2010 President’s Day Snowstorm





The 2010 President’s Day Snowstorm was the third and largest snowstorm to strike Columbus and Ohio during February, 2010. Models began showing the potential for another snow event in the Ohio Valley several days before. Initially, the track was well south, with only counties along the Ohio River being impacted, as this excerpt from the February 12, 2010 Area Forecast Discussion from Wilmington National Weather Service mentions:
MODEL SOLUTIONS CONTINUE TO DIFFER ON SYSTEM COMING IN SUNDAY NIGHT INTO THE BEGINNING OF THE WORK WEEK. THE GEM IS STILL THE FURTHEST SOUTH WITH THE UPCOMING SYSTEM. THE ECMWF HAS TRENDED NORTH WITH THE LATEST RUN AND IS NOW MORE IN LINE WITH THE GFS. THE ECMWF NOW ACTUALLY HAS THE SURFACE LOW SLIGHTLY FURTHER NORTH THAN THE GFS.
WENT WITH A GFS AND ECMWF BLEND. IT WILL BE COLD ENOUGH THAT PRECIPITATION WILL ALL BE IN THE FORM OF SNOW. MONDAY WILL SEE THE GREATEST CHANCE FOR SNOW WITH LOW TRACKING ACROSS KENTUCKY. ACCUMULATING SNOWFALL WILL BE POSSIBLE…ESPECIALLY ALONG AND SOUTH OF THE OHIO RIVER.

As the event grew closer, however, model solutions inched northward. On the afternoon of Saturday, February 13th, Wilmington issued the first Winter Storm Watch for parts of Ohio, but the focus continued to be south of Columbus.

By the morning of the Valentine’s Day, models had moved far enough north with the low track that the I-70 corridor was in line for much higher totals. At 2:43AM that day, the Winter Storm Watch was expanded into Central Ohio, with predictions of 5″-8″. By late morning, the Watch was upgraded to a Warning, and totals were upped slightly to 6″-9″.

Snow began in the area by 8:30AM on the 15th and was heavy through mid-afternoon. The bulk of the snow moved out of the area by Midnight, with only occasional wraparound snow showers continuing into the 16th.

The storm generally exceeded forecast snow totals across the region. Columbus received a record 9.7″ for the 15th, with a total storm total of 10.4″, making it one of the very rare storms to produce double-digit snowfall totals for the city. Since 1950, Columbus has had just 6 such events- the Great Thanksgiving Blizzard of 1950, April 3-4, 1987, February 14-17, 2003, March, 2008, President’s Day 2010 and February 4-5, 2014. Double-digit snowfalls have historically occurred roughly once every 12 years. It has been 9 years since the last one, but there have been decades between some of them.

Snowfall totals across Franklin County were 7″-11″, with the highest totals in the southwest. Most of the I-70 corridor south had at least 6″. Snow depths in Columbus reached record highs, with the airport having a post-storm depth of 14″, the highest February depth since at least 1939.

This was the peak event for the month, but not the end of February, 2010’s historically snowy run. A 4th, but far smaller snow event would occur towards the end of the month, bringing a general 3″-5″ across most areas. This would contribute to making the month the all-time snowiest on record for many areas. Columbus’ 30.1″ of snow for the month was the highest on record, and is the 2nd snowiest of any month to ever occur, falling just behind January, 1978’s 34.4″. Cincinnati, Dayton and other cities would also record either their top snowiest or 2nd snowiest February as well. Additionally, Winter 2009-2010 went into the record books at the 5th snowiest of all time. A truly memorable run!

The Great Thanksgiving Blizzard of 1950




The Great Thanksgiving Blizzard of 1950

Springfield, Ohio after the storm.

Exactly 67 years ago today, the Great Thanksgiving Blizzard of 1950 began. It was the biggest snowstorm for Columbus, and indeed most of Ohio, during the 40-year period of 1920-1960. That period, especially from the mid-1920s through the mid-1950s, had the lowest rates of cold and snowy winters of any comparable period. The average seasonal snowfall during that period was just 19.1″, a full 9″ below the average the 1980s-2010s have had to date. Still, the period was not without its memorable winters, including 1935-36, 1939-40 and 1947-48. None of those winters, however, had a snow event nearly as big as November 1950.

October 1950 had generally been very warm, ranking historically as the 19th warmest October in Columbus. Highs reached 65 or higher on 21 days of the month. This warmth lasted through early November, and the 80 degrees recorded on November 1st, 1950 remains tied for the warmest November temperature ever recorded. After that, the month seesawed up and down until a strong cold front and rainstorm on the 19th-20th dropped temperatures 25-30 degrees across the state, from the upper 50s-low 60s on the 20th to the low-mid 30s on the 21st. This front would be one of the catalysts for one of Ohio’s greatest winter weather events in its history.

Snow began in Columbus and other parts of Ohio on Thanksgiving, Thursday, November 23rd as a low moved through the Great Lakes and weakened. Behind that system, another cold high pressure was diving south out of Canada.

On Friday the 24th, a low formed on the stalled cold front that had moved through Ohio a few days earlier. Initially forming in southeastern North Carolina, this low would’ve normally gone out to see or moved up the East Coast as a Nor’easter. Instead, the strong, cold high pressure was moving into the Ohio Valley at the same time, and the little low exploded and as it began to move north. The strong push of cold was very evident in Ohio, as temperatures plunged from the upper-30s to upper 40s on Thanksgiving afternoon to single digits and low teens by early Friday morning.

The low moved into southern Pennsylvania by the morning of the 25th, and then began to do something few other storms ever do- it began to retrograde toward the west and Ohio, continuing to strengthen as it went. The unusual west movement was caused by a blocking high pressure system parked over Maine.

Light snow that had been ongoing in Ohio on the 24th quickly intensified from east to west across the state as the low moved westward from Central Pennsylvania to Northern Ohio by the end of the day on the 25th. With it arrived winds of 40-60 miles per hour, causing blinding white-outs and drifting.
Saturday the 25th was the height of the storm as the low pressure bottomed out at 978mb, a pressure normally associated with hurricanes. This day was, coincidentally, the famed Ohio State-Michigan rivalry football game, now famously known as the “Snow Bowl” for its terrible weather conditions.

With temperatures on Saturday morning in the single digits, wind chills well below zero and with heavy snow, there was debate about cancelling the game altogether, which was the Big Ten Championship. Ironically, despite the fact that Ohio State would’ve gone on to the Rose Bowl had the game been cancelled (Michigan did not want to reschedule), it was Ohio State’s athletic director who ultimately refused to cancel the game, much to the rest of the staff’s disappointment. Perhaps after the fact, considering Ohio State lost 9-3, that decision was regretted, especially in front of the more than 50,000 die-hard fans that managed to show up for the game.

Columbus would receive 7.5″ at the airport, with eastern suburbs getting up to 10″, just on that Saturday alone.

Due to the blocking high pressure, the storm didn’t budge for days, and it continued through the 26th and 27th before slowly dying out. The last accumulating snowflakes from this system fell on the 29th, 6 days after the snow began.

All in all, the storm was a record-breaker. Snow totals reached 10″ or more across most of the state except the far northwest and far southwest. In Central Ohio, snow had piled up between 10″-20″, with Columbus officially reporting 15.2″ for the duration of the event. This was the second-heaviest snowstorm in Columbus on record to that time, falling just shy of the 15.3″ that occurred February 17-18, 1910. Both of these storms would be surpassed by the February 14-17, 2003 snowstorm of 15.5″, which itself was surpassed by March 7-8th, 2008’s 20.5″.

Other totals in the state included up to 22″ in Cleveland, 27″ in Marietta, and reports of 44″ in Steubenville in far eastern Ohio. Totals of 25″-30″ were common throughout the eastern 1/3rd of the state. These totals are some of the highest the state has ever seen, coming close to those seen in the eastern Ohio snowstorm of April 1901.

In addition to the snow, record cold temperatures in Columbus of 5 degrees on the 25th (along with a record low maximum of 20) made this one of the greatest early winter events of all time.
