Strange Columbus The Wow Signal

Strange Columbus The Wow Signal Columbus, Ohio

No, we’re not talking about being able to get HBO from the modern cable company. This signal had even worse consistency.
On August 15, 1977, the Big Ear telescope– officially known as the Ohio State University Radio Observatory- recorded a surprisingly strong signal of non-terrestrial origin. At the time, the telescope was being utilized to search for signs of extraterrestrial life, a task that many large installations around the world had been occasionally involved in, with very little to show for the effort.

The observatory, located of of US 23 between Columbus and Delaware, had been working with SETI (Search for Extraterrestrial Intelligence) since 1973, after the installation had been deemed “defunct”. Equipment listening for frequencies would print out results on long sheets of paper, and while reviewing the data, the signal was first detected by astronomer Jerry Ehman at around 10:16PM. The readout featured the sequence 6EQEJ5, a combination that indicated frequency and signal intensity. The signal’s intensity was 30 standard deviations above normal background noise, and lasted for the full 72 seconds that the Big Ear was able to listen. Both the length and strength fell in line with expectations of what an alien signal would be like. Ehman was so shocked by it, that he circled the sequence and marked it with a “Wow!”, which is how the signal got its name.

The exact origin of the signal is even today unknown, but it was narrowed down to somewhere in the Sagittarius Constellation. Despite multiple attempts by the team at Big Ear, as well other other Earth-bound observatories to locate the signal again, they were unable to. This lack of repetition has meant that theories to its origin- either natural or otherwise- remain unconfirmed. Ehman himself was later skeptical of it actually coming from space and suggested it was signal from Earth that just happened to bounce off a satellite of some kind, but subsequent studies suggested this was highly unlikely.

For the next few decades, astronomers made multiple attempts to locate the signal again, but it was never heard again. To date, it remains one of the most mysterious space signals ever captured.

In 1997, the Big Ear ended all operations after 40 years of use. The following year, it was demolished to expand a golf course.



The Blizzard of 1996

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.

As the highlighted section shows, the Wilmington office was thinking 1″ or less for the I-70 corridor and points north, including Columbus, with only 2″-4″ in far Southern Ohio.
The first weather advisories for the storm went up at 5:20AM on Saturday, January 6th. For Ohio, this only included a Winter Storm Watch for far Southeast and far South-Central parts of the state, where 4″-6″ were predicted. No advisories were issued for the Columbus area until 4:10PM on the 6th.

SPECIAL WEATHER STATEMENT

410 PM EST SAT JAN 6 1996
…WINTER STORM WARNING FOR TONIGHT AND SUNDAY FOR SOUTHERN OHIO AND NORTHERN KENTUCKY…

SNOW WILL FALL THROUGH SUNDAY MORNING. EXPECT ROAD CONDITIONS TO
DETERIORATE THIS EVENING. DRIVING CONDITIONS ARE EXPECTED TO REMAIN HAZARDOUS OVERNIGHT WHEN HEAVIER SNOW BEGINS. VISIBILITIES WILL BE REDUCED TO NEAR ZERO BECAUSE OF BLOWING AND DRIFTING SNOW.

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.



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.
