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.

…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. IN
ADDITION…NORTH WINDS AT 20 TO 30 MPH WITH HIGHER GUSTS WILL
CAUSE SIGNIFICANT BLOWING AND DRIFTING…AND LIMIT VISIBILITIES TO
NEAR ZERO AT TIMES. 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.

The Blizzard of 1996

Posted on by

The first two weeks of January 1996 proved to be a very wintry period, culminating in the severe Blizzard of 1996. Although this storm was made famous for its effects on the Eastern Seaboard, it also had a significant impact on areas to the west of the Appalachians, and was one of the worst winter storms the state had seen in nearly 20 years.

This storm developed in the Gulf of Mexico on January 6th and moved up along the East Coast through the 7th. Forecasts for Ohio were not especially indicative of an impending major storm. A weak low pressure moving through the Ohio and Tennessee Valleys was supposed to die out as the main storm on the Coast took over. Therefore, Ohio was not forecast to be hit especially hard from this storm, as the Area Forecast Discussion goes into on the after of January 5th.

The Snow Advisory was only for 1″-3″ for Columbus even as the storm approached from the south. Later forecast updates at 5:55PM and 9:35PM on the 6th, and 12:35AM on the 7th still called for 1″-3″ for Columbus. Snowfall would begin in Columbus around 8PM on the 6th.

I have very vivid memories of seeing the afternoon and evening news on the 6th and being disappointed that the forecasts called for the storm to pass us well to the south and east. However, by the morning of the 7th, it was clear that the forecast had gone very wrong. Heavy snow and strong winds affected mainly the southern 2/3rds of the state, and the I-70 corridor was already reporting 3″-5″ by 6AM. By 11AM, Columbus had 4″-7″. Curiously, Wilmington wouldn’t add the I-70 corridor to a Winter Storm Warning until that time, after more than half of the snow had already fallen.

Blizzard conditions, however, raged across central, west-central and northwestern sections of the state, where winds gusted over 55mph in places. Blowing and drifting snowfall piled drifts several feet deep, and travel across the state was made impassible, particularly on country roads. For many, this was one of the greatest January snowstorms ever, and in some cases, the worst storm since the Great Blizzard of 1978. 8-10″ was common in the southern 2/3rds of the state, but there was as much as 15″ in parts of the Ohio River communities, as well as areas in west-central Ohio.

Some snowfall totals around Ohio:
Cincinnati: 14.4″
Circleville: 9.0″
Columbus: 9.8″
Dayton: 8.0″
Delaware: 7.0″
Mansfield: 8.0″
Westerville: 8.0″
Zanesville: 7.9″

So why had the forecast gone so wrong? The weak low pressure that was supposed to die off as the larger system wound up along the East Coast did not die out as expected. Instead, it moved into the lower Ohio Valley and essentially stalled as it slowly spun itself down. This low helped suck moisture over the mountains and into Ohio. Temperatures were cold enough for this moisture to fall as all snow, and a tight gradient brought with it strong winds. The result was a paralyzing winter storm and one of the all-time forecast busts.



The February 5-6, 2010 Snowstorm

Posted on by

The winter of 2009-2010 will go down as one of the best ever (if you like winter, that is). The biggest reason for that is February 2010 and its cascade of significant winter storms that placed the month as one of the snowiest of all time. The February 5-6, 2010 snowstorm event was one of the capping events of the month and winter as a whole.

The first event started in the morning on February 5th. Forecasts in the days leading up to this event were mixed. Models were showing a lot of precipitation, but also a strong push of upper-level warm air into Ohio. How far north this warm layer reached was the point of contention. In most years, the WTOD, or the “Warm Tongue of Death” as some Ohio weather enthusiasts like to refer to it, is a constant threat each and every winter. When a storm is moving north or northeast south of the state, they tend to pull warm air north, and the Appalachian Mountains act like a funnel directing this warm air straight into Ohio. During winter events, it presents itself as a layer of warm air above the surface, often turning snow to ice, sleet or just plain rain, even if the surface itself is relatively cold. It’s a constant source of frustration for winter weather lovers. It was this phenomenon that was predicted to strike again and the dividing line, as it so often is, was predicted to be along I-70/I-71. North of there, mostly or all snow was predicted, while south was more mix, ice and rain. The I-70 corridor, including Columbus, was to be the northern extent of this mixing, limiting snowfall accumulations. Still, even with the mix predicted, a solid 4″-6″ was predicted, which is a decent event by itself and typically the largest snow event of any given winter.

Precipitation began as snow across southern counties by dawn and spread north, reaching the Columbus area between 9AM and 9:30AM. It started out as flurries, but the flakes were already fairly large. Within 15 minutes, the flurries had turned to very heavy, wet snow. Flakes were as large as quarters at times and stayed large, accumulating quickly despite the above freezing temperatures. Visibility quickly dropped to a half mile or less at times, and traffic quickly snarled with accidents as plows could not keep up with the pace of the inch-per-hour snowfall rates. Between 4PM and 5PM, there was a respite as snowfall lightened and there was a mix of sleet and ice pellets, but all snow resumed once heavier precipitation moved in, concluding the only and very short period of mixing I-70 had. Snow continued through the night of the 5th and into the 6th, finally ending before noon.

Snowfall totals were impressive, especially along and north of I-70, where little mixing took place, but also in pockets to the southeast of Columbus, like Lancaster. For Columbus, the 9.9″ that fell was good enough to be a top 15 largest snowstorm for the city. It would not, however, be the largest snowfall of the month.

Some snow totals across Ohio from February 5-6, 2010
Greenville: 14.8″
Lancaster: 13.0″
Akron: 12.1″
Bellefontaine: 12.0″
Urbana: 12.0″
Westerville: 11.4″
Dayton: 11.1″
Springfield: 11.0″
Columbus: 9.9″
Youngstown: 8.4″
Delaware: 8.0″
Cleveland: 5.9″
Cincinnati: 4.5″
Circleville: 3.0″
Toledo: 3.0″

This event was the only the beginning of what would be a trio of consecutive snowstorms that would strike the area over the course of 11 days, including the February 9-10, 2010 Snowstorm, which occurred just a few days later.

The Wilmington National Weather Service, meanwhile, is a great source if you want to know the current weather in the area.



January 1999 Snowstorm

the January 1999 snowstorm Columbus, Ohio

Snow rollers in Columbus after the January 2-3, 1999 event.

In this episode of weather history, we’ll look at the January 1999 snowstorm that pummeled the Columbus area. New Year’s Day, 1999 dawned partly cloudy and cold in Ohio, a tranquil early January day in what had been until then a very warm fall and beginning to winter. Both November and December 1998 had been very warm months. December even had highs reaching into the 70’s early in the month, a truly rare occurrence. However, by the end of December, conditions had taken a turn.

On December 21, 1998, a cold front moved through Ohio, bringing copious amounts of rain. Most cities in Ohio received more than 1″ of rainfall, with several getting 2-3″. This front was the beginning of a very active period that would last for the next three weeks into mid-January. This pattern is not uncommon in La Nina winters, where the Midwest and Ohio Valley, in particular, are often much wetter than normal.

In any event, temperatures fell behind the front and remained generally below normal through the rest of the month of December, though no significant snow events came with the colder weather. That was about to change.

National radars on January 1, 1999 showed blossoming snow in the Great Plains, with cold air pushing south and abundant moisture pushing north from the Gulf of Mexico. Forecasts called for a significant winter storm beginning late on the 1st and lasting through the 2nd. The storm arrived a bit later than expected, but arrived in most areas during the overnight hours of the 1st/2nd as heavy snowfall. The snow initially fell at the rate of at least 1″ per hour, and thundersnow was reported from Cincinnati up through Dayton and Columbus.

During the day on the 2nd, warm air began to affect upper layers of the atmosphere, and the snow gradually began to change over to sleet and freezing rain, with an accumulation of ice of up to 1/2″ in some areas on top of the snow. By then, though, the damage was done. 4-6″ of snow fell in the Cincinnati area, with 6-10″ along the I-70 corridor. Up to 12″ fell to the north of there. Gusty winds created blowing and drifting snow at times, particularly in the northern areas that received less of a coating of ice.

Temperatures turned colder as the storm passed, and what precipitation remained changed back to snow showers by the 3rd of January. Temperatures would remain in the low to mid-teens for highs during the next two days before another storm would set eyes on the state.

Snow Totals for January 2-3, 1999
Dayton: 7.5″
Columbus: 6.6″
Cincinnati: 4.2″

The blizzard of 1999 affected areas far outside of Columbus.
Columbus weather history is full of such interesting events.
