March 7-8, 2008- Columbus’ Greatest Snowstorm




Repost

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.

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

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.

The first image below is a model snow depth forecast ending on March 9th. The second is a photo of the heavy snow in Columbus during the evening of the 7th.

Does Fall Weather Correlate to Winter Severity?



winter severity

Republished with data through the 2019-2020 winter.

As we go into the winter season, it’s time to talk about how this one might end up. There’s a belief that fall weather is a good sign of how cold or warm winter will be. Let’s see if that holds true.

First, let’s just look at October temperatures.
The October normal mean temperature for Columbus is 55 degrees.

Between 1878 and 2019, there have been 47 Octobers that featured a mean temperature of 53.9 degrees or lower, what we’re considering a Cold October for the purposes of this comparison.
Of those 47 Octobers, 27 of the 47 had following winters that were colder than normal, or 57.4%, 13 had average temperature winters, or 27.7%, and the remaining 7 were warmer than normal, or 14.9%.
Interestingly, this category contains both the warmest winter on record- 1889-1890 and the coldest on record- 1976-1977- as shown by the chart below.

Next, we look at Normal Octobers, which are +/- 1 degree of the 1981-2010 Average of 55 degrees.
Between 1878 and 2019, there were 45 normal Octobers. Of those, 21 had colder than normal following winters, or 46.7%. 11 were followed by normal winters, or 24.4%, and 13 had warmer than normal winters, or 28.9%.

Finally, let’s look at warm Octobers, which are those with means of 56.1 degrees or higher. There were 49 Octobers with warmer than normal means since 1878. Of those, 18 featured following winters that were colder than normal, or 36.7%. Another 19, or 38.8%, were followed by average winters. The final 12 winters, or 24.5%, were warmer than normal. Here’s the graph.

So just based on the October mean temperature, Octobers that are colder than normal are almost twice as likely as normal Octobers and almost 4x as likely as warm Octobers to be followed by a cold winter. But what about Novembers? It is closer to winter itself, so does its weather matter even more?

Colder than normal Novembers- 43.3 degrees or lower- included 80 Novembers since 1878. Of those, 38 or 47.5% had colder than normal winters. 22 (27.5%) had normal winters and 19, or 23.8%, had warmer than normal winters.

With the 39 normal Novembers, 43.4 to 45.4 degrees, there were 18 that had colder than normal winters, or 46.2%, with 12 normal winters (30.8%) and 9 warmer than normal winters (23.1%).

Finally, there were 24 warmer than normal Novembers since 1878- 45.5 degrees or higher. Only 6, or 25%, were followed by cold winters. An additional 9 (37.5%) were normal, while the last 9 (37.5%) were warmer than normal.

To reiterate, here are the ranked percentages of cold winters by the preceding October or November.
1. Cold Octobers: 57.4%
2. Cold Novembers: 47.5%
3. Normal Octobers: 46.7%
4. Normal Novembers: 46.2%
5. Warm Octobers: 36.7%
6. Warm Novembers: 25.0%

It should be no surprise that cold Octobers and Novembers have a stronger correlation to the following winters also being colder, with colder winters becoming increasingly unlikely as those months warm. What is surprising is that October weather, across the board, was more predictive of cold winters than Novembers were.

Going further, though, what about bi-monthly combinations?

Rank of Bi-Monthly Combinations and the percentage of colder than normal following winters, along with total years in sample:
Normal October/Normal November: 87.5% 8 Years
Cold October/Warm November: 57.1% 7 Years
Cold October/Cold November: 53.8% 26 Years
Normal October/Cold November: 48.1% 27 Years
Warm October/Cold November: 40.7% 27 Years
Cold October/Normal November: 38.5% 13 Years
Warm October/Warm November: 28.6% 7 Years
Warm October/Normal November: 25.0% 16 Years
Normal October/Warm November: 0.0% 8 Years

So a normal fall is clearly the best, but the sample size is not particularly high. Normal to Warm is unanimously warm, but again, it has a small sample size.

So does fall weather ultimately have a correlation to winter severity? To some degree yes, as patterns established in the fall tend to appear in the winter as well, but October, rather than November, has a clear higher correlation. But as with everything, there are many other factors involved.

October 2020 looks to at least begin with below normal temperatures, but it remains to be seen how it ends up.
