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!
